A belated log of the Chicken Wagon's life with us.

The snow tires on the SDL are going out, twisted belts or something, so I thought I'd un-retire this car for the remainder of winter driving season as it has snow tires on it. I drove it to the licensing place, where they vectored me to the emissions testing place. They tell me it's its last test! After that it'll be old enough to be exempt. Fortunately the car passed (not difficult for a diesel), but it's still not licensed. I'll have to go back another time.

While driving the car around I found that the RF brake was dragging pretty badly, the parking brake was inoperative, the brake fluid in the rearward reservoir is low, and the tranny was misbehaving rather scarily, at least at first. (Couldn't seem to solidly engage the final gear [4] unless I feathered the throttle.) That got better as the car warmed up. Sigh.

Wednesday, February 21, 2007

I polled the mailing list for suggestions on removing the neutral safety switch. Got a few, some helpful! Jacked up the car preparatory to surgery. Plan to work on the neutral safety switch, the dragging caliper, the parking brakes, the bad half-axle, and a fluid change for the tranny. (And anything else I find while I'm under there.)

Thursday, February 22, 2007

OK, I got the switch off. As predicted (not by me), there is no sign of internal shorting. Oh well, I always wanted to know how to take them off anyway! Back into the trunk I go, I guess.

What a grimy mess. For those who want to know, the tricks are to remove the crossbrace and the speedometer and kickdown couplings. That makes enough room in the area that you can use a wedge of wood to shift over the tranny to make a bit more room on the side. There is a rotating collar holding the connector in, that has to be persuaded to the right position, then the round plug (with funny angled boot) will pull straight out. Then you can remove the shifter linkage, yes the bolt must be entirely removed. (Same as for the speedometer cable.) With enough scrubbing in the area I found the two 10mm bolts that hold it in, one's above the shifter linkage and the other is above the connector. Then the whole thing pops off, and is ready for the solvent tank. (I didn't immerse it, just scrubbed it under the flow.)

While it feels kind of nasty for a switch, there was no sign of electrical problems. At least it's clean now! It's pretty solidly riveted together, in the absence of any overt problems I don't think I'll go in.

While under there I noticed that there are some (two?) missing rubber clamp buffers on the fuel lines. Will add it to the list. There's also some frame surface rust starting where the undercoating and paint is gone, partly due to a brake fluid bath. Must attend to that.

A disassembly of the taillight assemblies revealed no smoking guns. I took them completely apart, down to the individual socket level, and disassembled the wiring harness connector shells as well. Nothing, no signs of abraded insulation, corrosion, broken connector springs...

So, I hooked up a battery charger to the connector for the neutral safety switch (NSS) and ran the lights that way. Flexure and pounding did nothing, the lights just worked. Left with few other suspects, I drilled out the five aluminum rivets that hold the NSS together. (It is possible to have a pinched wire or something in the harness, but good luck finding that!) The inside of the switch looked good. A bit of crud built up in the bottom, if it was conductive it could maybe do some harm as the lamp switch contacts are very close to the aluminum cover there. But not so close as to make me suspicious. Otherwise the insides looked pretty good. I did notice that the 'hot' leaf for the lamps had more sideways flex in it than I'd like, if it got far enough out of plane it could perhaps contact the cover and blow the fuse, but that is really stretching it. To 'cure' this I put a blob of Shoe Goo over its mounting end, there should be no way once that is cured for the thing to flex much towards the cover. But I really don't expect this to have any effect. At this point I think I just need to put it all back together and see what happens, I'm running out of ideas. I am positive that the fuses blew upon shifting into reverse, I don't think it could have been anything else on the same circuit.

I'm going to have to purchase some suitable screws for putting the NSS back together, I don't think I have anything that will work.

A pissy weekend, it's been snowing and thawing. We got about 6" of snow at our house, most gone by mid-day today. Definitely not good working-on-the-car weather. But there was a nice sunny patch mid-afternoon, so I went out and liberated the sticking RF brake caliper. The pads are heavily worn down, the rubber sealing boot was not properly seated on the frozen side, allowing corrosion to set in. As I recall, the PO had said that he'd spent money at a shop having the brakes worked on fairly recently before the sale. Well, we haven't driven it much at all, and from the looks of this caliper he got ripped off.

Anyway, I determined to do the usual disassemble and clean job. Getting both pucks out is what is difficult, my grease gun and water trick can get one out easily, but sealing the hole up to pump out the other one is difficult. I end up putting the cleaned puck back in, but then getting it out becomes the problem. After much fiddling I got it out, slamming it out with compressed air when the other puck was loosely wedged in place. Both ended up loose, and I was home free. I hate doing that air thing...

The corrosion in the outer (non-sealing) parts of the bores was interfering with the installation of the pucks, so I'm trying the electric rust-removal trick on it in a bucket in the sink. I'll do the pucks too, just for grins. One of them looks a bit dinged up, I suppose I really should replace the entire brake assembly. But my spare is an ATE, not Bendix, and I don't want to get two new ones for a jalopy, as symmetry is supposedly important. Maybe I'll keep the need in mind for future trips to the U-Pull.

The pads were fairly well worn, and the pad sensors weren't even there. By combining the best of these pads and the used pads from the SDL I should end up with a passable set, at least for awhile. As was usual, one pad was worn a lot more than the other, the better one usually has quite a few miles left on it. I even have decent used pad sensors that I can install.

Oh, and the bolts I bought for the neutral safety switch are just a bit too short. Guess I'll get some more!

Monday, February 26, 2007

Washed off and blew dry the caliper. Looks good. I welded up a ring anode out of scrap strips of sheet metal and put the first of the pucks into the tank for de-rusting. I'm using the 6V setting on the battery charger since the items, by necessity, will be in the tank for many hours per. There is a lot of rust out in the open end of the puck, and a bit along the sides where it doesn't belong. This will be a stopgap, not a permanent repair. I expect this caliper to start to stick again relatively soon. Not this year, I hope.

...At lunch I bought some more screws for the neutral safety switch. They'll be too long, so I'll have to grind off the excess after assembly.

...This evening I switched pucks, the one in the tank was rust-free, though there is more pitting along the edge than I'd like. As I said, this isn't a long-term repair. I dried it and set it aside. By morning the other one should be well done.

Tuesday, February 27, 2007

Dried off the other puck. Looks good! I reassembled the caliper. Easily said, not easily done. Getting the rubber boots back on, with heat shields, is a real pain. But with the caliper reassembled I hung it on the car for storage. I've still got to properly install it, then move on to the car's other pressing needs.

Wednesday, February 28, 2007

What a fine day to finish the brake, NOT! Blizzard conditions, my brake parts and tools are buried in snow drifts. More than four inches accumulated this morning, and still coming down. Sheesh. Will work on the Frankenheap instead.

Friday, March 2, 2007

Still very cold out, but enough of the snow has left that I could find the parts and tools again. I did have to point my old half-radiant half-convective heater downwards to free them from the ice. The radiant heat was melting ice, the warm air was blowing on me. Nice! I reinstalled the brake caliper, with grease on the backs and edges of the pads. (I assembled the best set of pads from my used pile, and put in used sensors.) Remaining to do (on that corner) is bleeding and putting the wheel back on. I'm not sure I could get the hood open to get at the reservoir, what with the snow pile on it and the doors probably frozen shut too, but I didn't have time anyway.

Saturday, March 3, 2007

It's thawed enough to get into the car, so I topped off the brake fluid reservoir and bled the brake. Not easy to do alone, so I enlisted my 5-year-old son to man the brake pedal. He did a good job, and we got it bled out OK. I did notice one problem while bleeding: often when he pushed the pedal I heard a "splorch" up by the brake booster. Some examination showed that brake fluid was spraying out of a weep hole on the bottom of the master cylinder mounting flange. Great, I think it's leaking into the booster and getting pushed out. Time for a new MC, or at least a rebuild kit. I hope it hasn't ruined the booster yet. This also explains the low brake fluid level, and the streak of missing paint inside the engine compartment. Sigh, more work! I put the wheel back on and put on a bleeder cap, which it didn't have before.

Monday, March 5, 2007

Time to get busy! I greased and reassembled the neutral safety switch, then put it together with the too-long screws. (The 6-32's only came in 1/2" and 3/4" lengths at the hardware store, what I needed were 5/8".) I had to grind most of the head off of one so that it would fit under the locking collar. After it was all put together I ground off the excess thread length to prevent interference when putting it back on the car. Which I then did. That was a pain, for such a 'trivial' job. I didn't need to adjust the switch position after assembly, the reverse lights seemed to work right, as did the starter safety. If I need to, at least I'm familiar with it now.

There may be brake fluid leaking out of the LF caliper, it was hard to tell. I'm not impressed with the 'brake job' that the car had had before I got it!

Tuesday, March 6, 2007

I removed the RR wheel and brake caliper. The pads are paper-thin, but it otherwise seemed OK. I was able to use channelocks to squeeze the pads away from the rotor, so the pistons aren't frozen. It really needs new pads and a hose, and probably a rebuild as well. The drum came off with some pounding with a rubber mallet. There was a lot of rust inside, but the brake assembly looked good, shoes and all, and the drum didn't have much of a lip on it. (Nor did the rotor.) I used a wire brush to get off the rust, then the grinder to shave off the lip. (Before I've mounted them inverted to the car and used the engine to turn them like a lathe, but this time I just set it on a spare steel wheel. It would turn [by hand] in place much like it would in a lathe. With a light touch and some care I was able to shave off the lip with the grinder while rotating the drum so as not to put any divots in it. One hand spinning the drum while the other rests lightly on its surface, holding the grinder cocked at an angle so the wheel crosses the lip. Light touch with the grinder, never letting the grinder against the drum surface when it's not moving. It's harder to describe than to do.)

I had a look and both axles should be replaced as the one that's not split is soft, deeply cracked, and ready to fail. I do have a decent pair of spare axles for it, so that's no problem.

Wednesday, March 7, 2007

I removed the LR wheel and brake caliper, pretty much a repeat of yesterday's performance. The pads are better than the other side, but it may be that one of the two pistons is frozen.

I then found that the fill plug on the differential is completely ruined. No matter, in the worst case I can replace the rear cover with a different one. (I'll try removing it while it's off the car.) I scraped off the worst of the gunk and then removed the differential mount and the rear cover. I was then able to remove the two retaining clips (using small vise-grips) to free the two axles. Out of time, I put the cover back loosely afterwards to keep windblown dirt out of it.

...At lunch I bought some Permatex Anaerobic Flange Sealer, and its spray-on activator. This is probably the same stuff the MB dealer uses, recommends, and even gave me a tiny bit of once. Expensive!

Thursday, March 8, 2007

I removed the old axles. One was a bit rusted into the wheel bearing and needed some 'gentle persuasion', the other came out easily. Both axles had fibrous stuff wrapped around them inside the wheel bearing interface. (That's harmless.) With the differential mount removed, a floor jack can lift the differential body up high enough to make enough slack to free the axle shafts. I didn't have to loosen the shocks. The axle with the ruined boots was very loose and floppy when compared to the other three. The dirt had obviously been doing its, ahem, dirty work!

I cleaned off the 'new' axle ends in the solvent tank, then installed them. As usual, the small pair of vise grips is all that was required to install the retaining clips. (Same as for removal.) One very important point: make sure the differential-end spacing washers from the donor car are removed first, and that you retain the spacing washers from your car. They're likely different thicknesses, and the correct spacing matters. I also reused the former retaining bolts and washers.

The buggered fill plug, however, promises to be difficult. In the worst case I can always swap the back cover (with decent plug) off the old differential from the Albatross. I played with it a bit but I ran out of time, so I again put the cover on with two bolts to keep the dirt out.

Friday, March 9, 2007

I checked the part numbers, and the scrap differential's rear cover was the same as this one's, so I pulled it. I used the wire brush to power off most of the exterior dirt and grime, and a fair bit of its paint. Oh yeah, and it was full of that nasty sticky black sludge (I believe from one of the Albatross's PO's attempts to deal with its noisy differential). I spent quite a bit of time in the solvent tank removing the residue as it was quite tenacious, then I used brake cleaner to sluice off the solvent and put it in the shop oven to dry. A couple of rattle can coats of black paint renewed its baby freshness. (The oven at 200 °F really helps speed this up.) The breather was also clogged with goop, solvent and compressed air helped open it up. Made a bit of a mess, though.

With that done I cleaned the mating flanges with brake cleaner and a putty knife. Then I sprayed the Permatex Surface Prep on both (should only do one says the goop tube—the spray can says to do both but I'm inclined to trust the goop's label on this, too bad I didn't read it first) and let them dry. The Permatex Anaerobic Flange Sealant is not the same as the runny orange stuff I once got from the MB dealer, it is thicker and purple. Oh well, I'm sure it's good stuff, it certainly cost enough. I ran a small bead around the cover and then bolted it down. At this point I was again out of time.

Saturday, March 10, 2007

I used the floor jack to push the differential back into position, then bolted it in place. Next I filled it with fresh oil, which was a tedious squeeze-fest using those pointy oil bottles. I tried not to snug the filler plug too tight, we'll see. Then I put back the brake drums and put on the calipers. (They'd been sitting on top of the brake backing plates, still plumbed.) Next were the wheels, no problems. At this point I went under and tightened the parking brake adjustment as much as was reasonable. One side seems stretched, it may not work well. Its cable was very stiff too. The other side seemed a lot better. Next I removed the two cushion-less hard fuel line clamps, cut some pieces of rubber fuel hose and slit them open, then clipped them around the fuel lines, then reinstalled the clamps. Perhaps not as good as the real deal, but much better than nothing. Finally I installed two more rubber exhaust donuts to replace the missing ones. Then I cleaned up the mess I'd made, and drove the car off the ramps. Time to take it in to be licensed!

...And off we went! Uneventful, except there was a bad shift or two. We got the license and came home, where I parked and left the engine running. I then checked the tranny fluid, and I believe it was very low. (But I am notorious for having difficulty checking the ATF level.) I put in 1/2 quart of ATF I had laying around, we'll see if it affects the shifting positively. While it was running I ran down the driver's window and put some weatherstrip glue on the torn part of the channel at the top. With it still down I let the glue get tacky, then pressed the torn strip back into place. I left the window down a crack so as to keep tension off of the channel until the glue fully sets. I then removed the sun-baked and cracked passenger seat (my wife won't need this right away) and set it aside. Out came the vacuum and I sucked up all the mouse poo from storage. I pulled all the carpets and the rear seat as well. The jury-rigged cupholder came apart, so I glued that back together. (My wife insists on that and a radio, nothing else is supposed to matter.) I then pumped up the spare tire and buttoned things back up. The remaining cosmetic items should be done over the next few days, but as of now this thing is a driver!

...Which my wife promptly used. She was quite pleased, except for the badly-cracked windshield. We also went to dinner in it, and it was quite pleasant. Quiet and comfortable, and no bad tire wobble. She and I noticed no shifting anomalies, so it looks like low fluid was definitely to blame. I'll dial that in over the next few days.

Sunday, March 11, 2007

I removed the chewed driver's-side B-pillar cover and peeled off the ruined windlace, both front and back. I grabbed the decent used pair that I'd stored in the trunk and installed them instead. I painted contact cement down the glue stripe on the frame with a small disposable glue brush, and pressed the 'new' windlace strips into place. I placed the sun-baked ends down, where they don't show quite so much. I removed the bottom seatbelt retaining bolt and slipped the B-pillar cover off. I then reinstalled the replacement pillar cover from the trunk. Looks a lot better! Too bad I only had the two windlace strips, the car needed four. (I wonder if the good bottom halves can be pieced together into something that looks presentable? I'll look into that.) I then cleaned up the smudging with Simple Green, and got it ready for my wife's use just in time.

...Many complaints from my wife about the windshield. Besides the cracking from road rocks it's also pitted from road sand. She also didn't like the level of illumination from the instrument cluster. (On a 123? Imagine that!) And she was annoyed to find that the Becker tape deck wouldn't accept a CD! Sheesh, honey, I don't know what you want. It doesn't wobble on the road and it has both a functioning radio and a cupholder. Were those not the main criteria? At least it's clean and quiet.

The windshield replacement job scares me, I hear it's rather difficult. I have a good used replacement and a new rubber seal. My big plan had been to pull the badly-cracked and chewed dash (for replacement and for repair of the center vent ACC pod) and, while it and all the associated window trim was out, to try tackling the windshield then. But I don't want to attempt any of this while the car is in service.

Monday, March 12, 2007

I removed the B-pillar cover on the passenger side to expose the windlace. While there I noticed some mold in some of the seat belt, so I got a bucket of water and some Simple Green and washed it out. I then pulled down the ratty windlace pieces, front and back, and snipped them off to leave the still good parts in place. Then I took my collection of ruined windlace, cut off some good ends, and pieced together a serviceable, if not beautiful, set of windlace out of it all. I just glued up the pieces much as if it had been a new set. It doesn't look as bad as you might think, but it in no way can be mistaken for a nice new set! Better than it was, though. I then reassembled the B-pillar.

...Tonight while driving I had a serious transmission non-shifting episode. After the panic cleared I remembered that it's done this before, if you drive too much/fast with it held in first gear (as I often do in parking lots) it won't upshift once you take off unless you come to a complete stop for a bit. I'd forgotten, and on the road it would rev and not shift, then slip and not accelerate at all, etc. (Rolling while in neutral does not clear it up.) A total mess. Pulling over and sitting in park for a few seconds restored it to normality. This transmission is not right! But I think we can learn to work with it. My wife, however, will probably not notice this, its worst problem, because she uses the brakes rather than the shifter. (I use it to prevent upshifting when I don't want it to do so, I don't use it to force downshifts.)

Tuesday, March 13, 2007

I went into storage and found the best spare seat. Unfortunately it is about as discolored (from sun) as the existing seat, but at least it is not all cracked. The back might be a little better, but there are some chewed spots in the side of the would-be replacement. I'll just have to be content with replacing only the bottom cushion. I separated the two seats' halves and cleaned the new seat bottom, but I ran out of time to finish the job. It takes a fair bit of time to do seat work. And space! I was spread out in the yard (a soft place) trying to avoid all the nasty bones the dogs have littered all over the place. Unfortunately the seat tracks have to come all apart in order to liberate the frame assembly, and that takes even more time.

Wednesday, March 14, 2007

I tackled the bad brake light I noticed yesterday as my wife drove off. The bulb was good, but the socket area was badly corroded, as was the barrel of the lamp. I got out the Dremel wire brush and went at it. Ditto the parking lamp, though it was still working. I replaced one of the dead rear side marker bulbs, but I only had one spare and both were burnt out.

The glove box door was down because the latch assembly had again gone 'sproing' and wouldn't work anymore. So I teased that back together again. What a steaming pile! I've never seen one of those 123 doors that works very well. The design would probably be good if it were all metal, but the plastic deforms too much and then it jumps track. I've got to tell her (again) to treat it very gently.

With the fraction of time remaining this moning I got the seat tracks moved over to the other seat bottom. But that was it.

Thursday, March 15, 2007

I put the two seat halves back together, and swapped on a better hinge cover from the donor. (The trick to removing these without breaking the snap ears is to spray a little soap on it then slip a tight socket over the end then whack it with a mallet.) I mopped off the worst of the dirt and grime with Simple Green, then installed the seat. Looks good!

I also replaced the remaining rear side marker bulb with one my wife bought yesterday.

Friday, March 16, 2007

I had a look at the spare window regulator I bought, and found it to be probably as bent as the one that's in there! The regulator's wretched pot-metal base plate is a bad design. (Too thin.) So I disassembled it a bit and took it to the anvil. I got it mostly straightened out (which I have done before and found not to last) when I hit it once too many times and cracked it. Crap! I was looking at it trying to figure out how to bolster it with some steel, but I'm not sure that any such measure will work once the thing has cracked. And zinc pot-metal just doesn't weld. Now I'm not sure what to do, will have to think.

Saturday, March 17, 2007

Fluids time. Put in engine oil (needed a fair amount), more transmission fluid, windshield washer fluid, and a bit of water for the radiator. Power steering and brake fluids were fine.

Sunday, March 18, 2007

Started messing around with the ruined window regulator. Did a bit of surfing, and found that zinc castings can be welded or soldered, but not easily. Not at all. One source implied that most such castings should be treated as aluminum for the purposes of soldering. I had some aluminum solder, so I thought I'd try it. First I wire-brushed the area to clean it off some. The feeble propane torch wouldn't even begin to heat things properly, so I got out the acetylene. Oops! That is a bit too hot, the cracked casting slumped and holed before I could even begin to solder to it. But what I did notice was that where it had melted into a big drip there seemed to be no longer any crack. Throwing caution to the winds, I vise-gripped a steel backing plate across the crack, slopped some acid on there for flux (fizz city!), and used an old-style broken door check body for filler. I then proceeded to make a real mess. While things did melt, the zinc tended to want to burn out of the metal, and I never got good puddling. I suspect in part that my filler material wasn't quite right. Eventually I got tired of messing around and had a look at the results. Nasty-looking! But there did seem to have been some strengthening, at least when compared to a zero-strength crack. I then decided that I'd had enough of the melting, and dug out some of my epoxy glues. I mixed up a big wad and potted the whole area in the stuff. I have no idea if it will set up with any strength or not, but at this point I have little to lose. I think it'll grip all right because the melted area is all wrinkly and lumpy, there should be lots of surface area. I set it on the wood stove (which is on low) to cure after it had set up enough to avoid dripping.

Really I think I'm going to have to find a good regulator to install into the car. While I haven't looked yet, the 'chunker' is one I believe that I worked on before, trying to straighten out the nasty pot-metal casting. It's either bent again, or has cracked where I straightened it out. Either way I doubt it's salvageable any more than this one I've been killing.

Of interest is that both the 450 SEL currently in the junkyard and this 300D, according to the EPC, use 116 730 21/22 46 (L/R) window regulators. Maybe I'll stop by the yard today and see if the regulator is still there and any good. Doubtful, but worth a shot.

...So I dropped by the yard after church. There was a swarm of guys stripping the 450, one of them had just bought a grey-market '80 380 SEL for $50. They'd had to yank it out of a swamp where it had sat for two years, the PO was going to enter it into a demolition derby. The new owner fiddled with it a couple of hours and got it started then drove it home. He didn't know too much about such cars, and appreciated knowing a few things about it. (Unfortunately his fuel pump packed it in as it sucked on the dregs of the tank, and the one from the 450 was long gone.) I tried to tell him that the steering column he was liberating from a 116 was likely no good in his 126, but oh well... In spite of the buzz of activity I was able to nab the appropriate window regulator from the car. Seriously warped, but still intact. We'll see how it goes.

Monday, March 19, 2007

I ground off some excess epoxy so the sector gear could clear the repaired area. Flexing it by hand it seemed strong, it didn't immediately crack off or anything. Thus having not one, but two potential replacement candidates I opened up the door to have a look at the 'bad' one. Yes, bent. But not broken. In fact, overall it's less bent than the one I bought yesterday, though it's bent more right at the motor hence the 'chunking'. Since the door really isn't that hard to open up I decided to gamble on the welded/epoxied one since it was the straightest of the bunch. I kept the original motor because the connections had been cut off the spare's. It seemed to run OK on the battery charger I was using to run it, so I buttoned it back up. All went smoothly, we'll see how it holds up. I have the other two in reserve if I need to try again later.

As of today the short list is more-or-less done. Time to do something else for awhile. I promised my wife I'd build a shelf in the closet.

...My wife called me at work and during the course of the conversation I reminded her that the sunroof worked on this car. She was excited, as the weather was very good, and it turns out my son was really excited to have it open. However, when it came time to close it again, nothing. I came home a bit early to take care of it and found the switch not making good contact. I took it apart and burnished it so it worked again. I decided that this was also a good time to address the center tube lubrication issue that I missed the first time I had it apart. I didn't have to take everything apart, just the headliner panel, and the six screws/bolts and retaining clip that hold in the black drive bar. With that all out I could swab out the center tube of the drive bar, and I could also mop off the outside of the cable sheath where the drive bar's tube slides over it. (This being the lubrication point I didn't address the first time.) I then put some Lubriplate inside the drive tube and reassembled everything. It worked fine again.

Harbor Freight was having a sale. (Got a fuel-pressure test kit that has Bosch CIS fittings in it. $70. The diesel compression tester is again on sale at $17.) But what was particularly interesting was a 1# box of Alumiweld rods. These are some kind of zinc alloy meant for brazing aluminum and pot metal. $12, usually it's more like $20 there, or $30 elsewhere. The printed instructions were fragmentary and the importance of a clean dedicated stainless steel (no substitutions!) cleaning brush was not made sufficiently clear. I think I may go back and get a brush, and maybe another 1# box of rods. This is the stuff that would probably have been very good for fixing the window regulator.

Thursday, March 22, 2007

Went back to Harbor Freight, bought more Alumiweld. They didn't actually have a stainless-steel brush, so I bought one at the hardware store that's adjacent to my work. (And a couple of 6" Phillips screwdrivers that I needed for another project.)

Saturday, March 31, 2007

I decided to surprise my wife by putting the portable CD player (Sony Discman) in her car. (I bought her some books on disc she might like.) When I put the cassette adapter into the Becker it blew its fuse. Not the car's, but the one in the clip-on holder behind the radio. When I pulled it out enough to temporarily bypass the (undersized?) 2 A Euro fuse, I found it wouldn't retain the cassette adapter. The tape safety was kicking in. I opened up the Becker and had my memory refreshed by the sight of belt pieces floating around. Oh yeah, the cassette in this was defunct! I'm mulling over ways to bypass the tape adapter right now...

So, the Becker 599 Europa Cassette has a rear-panel DIN connector for external sourcing, but it's mono, not stereo. So that's out. Internally the cassette transport mechanism is a hinged subassembly. It unplugs and pivots out, then you pry the snap-ear hinges open a bit and remove the whole thing. Easy. Removed, you lose the four tape buttons and the dial/band-selector light. There is a four-pin connector (with only three used) and a three-pin connector on the main board for the transport. The three-pin is for the head: the center is common ground, the pin towards the volume control (black) is R, the remaining one (red) is L. It seems to be 'hot' at all times, even with the radio playing on the bench touching one of the signal pins results in superimposed hum. On the four-pin connector the big red wire towards the tuning knob is +12 V, the next one is a no-connect, the next (yellow) is switched by the transport to +12 V to disable the radio, and the last (black, towards the volume control) is grounded by the FF/REW buttons on the transport to attenuate the signal. Ground is through the metal chassis. It should be relatively easy to fabricate a plate of some sort to cover the tape button hole, and to rig some jacks into which to plug the CD player or her iPod. (The iPod is the real reason I'm going to this much trouble, an auto CD player is not expensive. Ones new enough to already have an iPod jack are expensive, and have 'steal me' written all over them. Unlike old Beckers. And if I'm going to operate it makes sense to do it on an old Becker of little value. And let us not forget that this is the Chicken Wagon, after all.)

I suppose that I need to plan out what I want to do. OK, in a perfect world the cover plate will have a mini phone jack for the iPod/Discman, a mini power jack for the Discman, a USB jack to power the iPod, and an incandescent lamp or bank of LED's to light up the tuning dial and band indicator and to indicate (by omission) that the auxiliary input is active. The USB jack requires 5 V, the Discman requires 4.5 V. As the Discman uses a 3 V non-rechargeable battery pack I suspect that the 4.5 V is not too critical, and that the Discman and USB power plugs can thus share 5 V. That means only a single 5 V regulator is required. USB calls for 500 mA, the Discman's adapter is rated about the same. If I make the cover plate out of metal it should be a nice heat sink for a 7805 regulator. Perfect. Now I need to scrape up some parts, it's probably time for a trip to Radio Shack.

...Did some research at Radio Shack, and did some surfing on the Internet for the iPod dock connector. Radio Shack has changed a bit since I was last there, not much in the way of parts anymore. Nothing compelling there today, though they did have a bunch of iPod accessories. Did better with the Internet, I found an inexpensive source for the docking connector, and found some specifications on wiring it. I think I'm going to have to mail-order any parts I need. More research is required.

Anybody ever noticed that there's a lovely iPod-sized blank spot in the 123's upper switch bank? You could put an angled docking socket there and the iPod would be perfectly placed for use. I doubt I'll do it, but it is an intriguing thought.

Started working out the fabrication of the cover plate for the hole in the Becker. I'm not exactly sure which jacks will end up in it, but "Have drill, will travel!" I'm thinking that the mini-DIN serial connector/cables from an old Macintosh will work well for the radio end of the iPod link, I have some parts boards I bought just for this kind of thing, if I can find them! Pretty sure I ought to put regular power and phone jacks in too, though, for the Discman etc. (The only problem with the Discman unit itself is that it refuses to play recordable media. I know that Sony did this on purpose, and it bodes ill for the Discman's long-term suitability for any car of my wife's. She's a musician, and symphony-issued compilation CD's for rehearsal purposes are a big part of her automotive listening experience. I am assuming that there are other, less limited, units out there on the trailing [cheap] edge. It's probably easier than getting her to burn them to the iPod on the computer and then just using that. In her own way she can be just as reactionary as myself. But I'm angling for the iPod connection, which is why I don't just replace the head unit with a suitable CD player.) While I was in there I realigned the band selector letter indicator (U/M) with its window. It's adjustable, and has always been a bit off.

Monday, April 2, 2007

Started compiling my parts order. More involved than I thought!

Tuesday, April 3, 2007

More parts compilation. Kid in a candy store time! Parts finally ordered.

Tuesday, April 10, 2007

Some parts have come, but not all. I started fabricating a steel plate, to replace the cassette transport's face, which will carry the jacks.

Wednesday, April 11, 2007

More fabrication. It's not easy making a 'stamped steel' faceplate filler piece!

Thursday, April 12, 2007

Out shopping I bought two different non-Sony portable CD players, $1 each at the thrift shop. (It is said that Sony, owner of Columbia Records/Video, deliberately made their player incompatible with recordable CD's, and recordable rehearsal CD's are a part of my wife's musical career.) The older player has line out, but wants 6 V power. We'll see if it works well on 5 V. The slightly newer one wants 4.5 V, and has only a headphone output. I'm hoping one of these will work well for this application, naturally I'd prefer the one with line out.

Friday, April 13, 2007

The fabrication is not going well, I don't have dies in which to form the piece I thought I needed. It came out too big in one dimension and was interfering with the radio dial cord. So I cut it in half which relieved some of that overdimension, then I tack-welded it back together. (I think that for such things welding up multiple pieces of simple 90° bends made with the vise would ultimately work better.)

However, as I worked with it and the faceplate it seemed clear to me now that my original plan to replace the tape button array with a socket panel will not work, there isn't quite enough room for the sockets I intend to use. (I sort of forgot about the plastic faceplate, it covers part of the hole.) So I moved on to Plan B. I traced and cut out a piece of sheet metal that exactly fills the hole in the faceplate that is the combined area of the tape hole and the button area, in effect making the bottom part of the faceplate a solid area. With some grinding and filing this will fit well, though I have to relieve some areas on the back side to result in a flush fit. (More hacksaw and file work.) I will then attach this panel (somehow) to the subpanel I have made that fits behind the radio dial and bolts to the old transport retaining points. (This subpanel will still be important in restoring the dial lamp, and as a heat sink for the 5 V regulator, and for providing electrical ground.) The jacks will come through the panel where the (larger) tape hole was. I was hoping to recess them a bit, but that cannot be with Plan B!

The parts came! That 2.5mm power socket looks awfully large though. May have to rethink that one.

Saturday, April 14, 2007

The USB jack, though large, still fits through the tape slot. The power jack is a big issue, I'm not sure what to do. It doesn't fit the cable I bought for it, and it's borderline too large to fit through the tape slot. Will need to do some more shopping, I think. I checked, and the older of the two $1 portable CD players (with line outputs) works on 5 V and plays Jill's CD-R rehearsal CD's. It's a GPX, whatever that is. So it's in. (The other, Lenoxx Sound, turns out to have a broken hinge and otherwise doesn't seem to have any better features.) I just need to figure out the cabling. One end of the power cable I bought fits the CD player, poorly, but the other does not fit the chassis jack.

I filed and ground the filler plate so that it fits well, including necessary relief chamfers on the back to tuck into place. I then welded and cut the rear plate so that it no longer covers up the tape slot. I next need to figure out how to attach them together. (Then on to cutting the holes in the filler plate for the connectors. Scary.)

...I stopped at Radio Shack to check out their connector bin, and found a pair of power plugs that fit the CD player and their mate for the front panel. So I'll probably just cut up that cable I bought and put new ends on it, then use the RS jack in the face. Not quite as pretty, but at least it's a size I can use. And I really can't put this off any longer.

Sunday, April 15, 2007

Not much time today, but I did make up the power cord. (Cut off the old ends and soldered on the new ones. I had to drill the plastic caps a bit to let the large cord fit through. Looks decent.) Drilled the mounting holes for the rear plate. A drop of oil really helps it drill, and I used the Variac to slow down the Dremel to a more suitable rate for drilling metal.

I ran the GPX portable CD player using the new power cord, and I finally thought to check its shock resistance. Not great, we'll have to see if it works well enough in the car. It also doesn't have a resume function, it starts over each time it's powered back up, or even stopped. There are other players out there, if this one turns out to be unsuitable. (The Sony has excellent shock resistance and a resume option, too bad it's no good for my wife's purposes.)

The power jack has a separate 'inserted' contact, I think I can use that to gate off the radio. (Need to invert it.)

Monday, April 16, 2007

The inversion of the power jack 'signal' should be easy. I have a tiny 12 V incandescent bulb for lighting the dial, if I just hook it between the switched ground pin of the jack and +12 V I can tap the bulb's ground side directly for the radio shutoff signal. It doesn't get any easier than that.

I got the front panel mounted in place, I drilled through both panels and ran long screws through. Once everything was aligned I stacked nuts on the back side of the front plate to make standoffs. Without these spacers the panel bows when the nuts are tightened. I may or may not weld the bolts in place and grind off the heads on the front. We'll see how it looks once all the connectors are mounted, it may be that two more screw heads will be nothing to worry about. The front plate seems very solid, this is good. I then began marking it for the connectors. I've got to get this right, I don't want to ruin the panel, it's too hard to make another one! Current plans are to put in the USB power plug, the coaxial power jack, and the 1/8" phone jack, and to forgo the mini-DIN. That will require two cables to plug in for both the CD and the iPod rather than the single cable I had in mind for the iPod, but that's how it works out. I don't think there's room (on the inside of the tape slot) for another large-ish connector, and I want the USB connector for charging purposes.

The profile of the two sheet metal pieces is:

|
|o  <------- New dial lamp
-----
    |__|  <- Bolt intertie
    |  |
       |  <- Face plate covers all tape holes
       |
       |

Tuesday, April 17, 2007

The holes are now cut in the faceplate. (I tried to leave enough free space for the mini-DIN if I should ever want to add that.) Cutting the rectangular USB hole was the worst, since you have to drill, hog out between the holes with the Dremel and a burr, and then file to final shape. (Using a ratty rusty old file that was the only one I had small enough to fit in the hole.) Time-consuming. The two round jacks were a snap by comparison. The face metal is thick enough to take a semblance of threads for the two round jacks, so they can be screwed in flush and locked from the rear. I really like the smooth appearance that this gives it, so I think I'm going to weld all four through bolts in place (two to mount the plate, and two for the USB jack) and grind them flush with the face, converting them to studs. More scary stuff!

In the evening I tried out one of the new surplus USB workspace lights. Pretty feeble, nasty, cheap things. May be good for a gag gift, but not going to be much of a car map light! In a dark room it does throw a tiny amount of light on the center of the keyboard, that's about it. Oh well, the radio's USB jack is really for charging toys, not lighting.

Wednesday, April 18, 2007

That was fun! The welder is a bit rude and crude for such small work. (No surprise, that.) I had quite a bit of trouble with the larger bolts that hold in the USB plug, and almost none with the longer thin ones (with nut stacks on them) that hold the faceplate on. I had to do a lot of grinding and filing to put things back more-or-less right. There was some dimensional shrinkage, but I don't think it'll look too bad in the end. I also ruined one of the new USB studs, but I think I can put a dab of glue on it to hold things in place. Not my favorite idea, but it should be fine. After all the metal work I took the plate to the belt sander and smoothed off the face, then rattle-canned it with primer and black paint. I used the shop oven to hasten the drying between coats. The plate is hanging on a wire to dry now. With luck, tomorrow I can begin installation and wiring. (I still have to mount the dial lamp and the voltage regulator to the interior plate, and paint the lamp chamber white.)

...After work I fiddled with it a bit more. I installed the connectors, and ended up having to glue the one nut on its chewed stud. The glue accelerator messed up the face paint a bit, so I had to respray that too. It's still not perfect, but I really need to be getting this done, so it'll stand as-is for now.

Thursday, April 19, 2007

The rubber mounting ears for the USB plug protruded a bit on one side, I used the Dremel burr to shave it so the plate will fit easier into position. The white center plastic piece of the USB connector was a bit 'bright' against the black face, so I used a Sharpie to touch it up.

Time to finish up the rear plate. I drilled holes for the new dial lamp and the mounting screw for the voltage regulator, then primed and painted (white) the interior lamp chamber. I mounted the 7805 regulator, put wires on all the connectors, and installed the plates. The 7805 is a metal-tab TO-220 version, this is important here because this is the main ground point for all the new accessories. I took care to ensure a solid connection. Continuity to ground on the regulator (which is through the metal and mounting screws) measured good. The stereo jack is a very tight fit given its nature and location, I hope I don't have trouble with it contacting ground.

The faceplate doesn't look quite as good as I had envisioned, but it doesn't look as bad as it might have, either. It's going to be good enough. By decree.

...After work I started wiring it up. I put in a basic 3-terminal 5 V regulator circuit, with all three protection diodes, an input electrolytic capacitor, and an output mylar capacitor. The 14 V grain-of-wheat dial lamp is hooked between the regulator input and the switched ground of the power jack. (I had to sheath the bare lamp wires using insulation stripped from some telephone wire, I used a dab of cyanoacrylate glue to hold the insulation in place at the lamp.) The switched ground is also run to the Becker's radio disable connector pin, the lamp acts as a pull-up resistor when the jack's in use. The USB jack's power pins are wired in parallel with the main power jack and to the regulator. Using the USB jack does not disable the lamp or the radio. I stuck a little notebook computer work light in it and it worked. I used loose DB-25 connector pins (sockets, really) to attach to the Becker's transport power connector pins. A dab of Shoe Goo holds the two wires (power and radio disable) in relative position, I'll do some more gluing to fake having a connector shell. (I have a close-enough mate to the three-pin audio feed connector, no need to screw around there.) The wiring is very haywire point-to-point rat's nest, but it should serve. No one will see it in operation.

With the circuit checked out and powered up the dial lamp worked correctly. You can also hear radio background noise cut out with the dial lamp. (No antenna, so no signal.) I plugged in the CD player and it worked! The line-out feed from the player is much too 'hot', I'm going to have to attenuate it. I used a 200kΩ potentiometer from the junkbox to turn it down and it worked much better. I'm also a bit concerned that the head feed from the Becker transport might be equalized in some fashion that is incompatible with line-in usage. More research is required, in the worst case I just have to trace out some more circuitry to find a better input location. I need to get out a decent speaker and my Sheffield test CD to do some more research. I've been using an ancient transistor radio speaker and a Carmina Burana CD that is much too quiet most of the time.

I checked the dial illumination in the dark and it looks good. I will need to tape off the former 1 & 2 track LED holes. The illumination is probably not quite as even as the original had with its plastic light spreader bar, but the bulb looks to be about the same and the illumination level is good.

Friday, April 20, 2007

A small piece of black electrical tape took care of covering the tape track lamp holes.

I found my Sheffield test disc and a spare Radio Shack Minimus 7 bookshelf speaker. (They had a decent reputation for their size and cost back in the day.) Once I got everything wired up again it became clear that head equalization is definitely an issue. Pressure Cooker's Dish Rag sounded, well, limp. Muddy, in a word. I think I remember now that tape EQ is a big feature of the tape recording process. I dug out a 0.0047 µF capacitor and jumpered it across the attenuator, and there was serious difference. Probably too 'hot' now. More research is called for, but I think I can come up with a passable un-EQ attenuator circuit.

Surfing yields the fact that tape EQ is 6 dB/octave, due to the basic physics of magnetic recording. And that a simple RC network (one each) provides 6 dB/octave. So I was on the right track, and merely trying out a few capacitor values from the junkbox will probably be sufficient.

I found that the attenuation potentiometer was set at about 200Ω, out of 200kΩ! The junkbox had a plethora of 150Ω resistors, and several 0.010 µF dipped capacitors. I found that two such capacitors in series (resulting in about 0.005 µF) feeding the 150Ω resistor in a classic high-pass configuration seemed to work well. The audio sample tracks sounded decent, and the overall volume approximately matches the radio's. (I hate getting blasted when switching from one to the other.) I also checked the left/right channel assignment using the test disc, and made sure it was correct. I then wired it all up, more rat's-nest. It sounds good!

Now I just have to physically secure the circuitry a bit, especially the stereo jack and the internal transport power connector, then install it back in the car!

Saturday, April 21, 2007

Finishing day! I made a schematic for future reference, in Illustrator, PostScript, PDF, and GIF formats. I took some pictures (inside, outside) and slipped a piece of cardboard in above the stereo jack's connections, then buttoned it up. After a quick check of functionality I ran it out to the car and installed it. (I had to dig up a new 5 A Euro fuse.) It seemed to work fine, so I hooked up the GPX player and slipped in a CD. I presented it to my wife, and told her that if that CD player didn't work out we could try others. She seemed happy to get the radio back. Sorry it took so long, babe!

Sunday, April 22, 2007

Now I'm starting to remember that this particular Becker had serious volume control problems, and that I worked on it a lot years ago in order to get it sort of functioning again. (I may have transplanted the volume control from an older model, I know I did that to something.) But it has left the right channel 'weak', and the left channel with a non-functioning tone control. I poked around at it for awhile on the bench, but nothing was accomplished. I may try to find another, better, radio to move the mods to. No rush, though.

Tuesday, April 24, 2007

A fellow lister has another Becker I can purchase. $20 w/shipping. Will see if it's any better when it gets here. (Or at least I'll scope out the internal wiring.)

Thursday, April 26, 2007

I glued the hinge pin back onto the Lenoxx Sound CD player. That'll give my wife another choice. I used cyanoacrylate glue to tack it in place, then potted it in Shoe Goo. I also bolstered the hogged-out center hole of the Becker's tuning knob with a bit of cyanoacrylate glue. It feels somewhat better now, the slop is gone.

Friday, April 27, 2007

With the glue dry the cover snapped back onto the Lenoxx CD player, no problem. Good as new! (Except for the missing battery hatch cover.) I'll throw it in my wife's car, she can try it out too to see which of the two suits her better. (No line-out on this one, so she'll have to watch that volume control.)

Sunday, April 29, 2007

Jill reports that the Lenoxx CD player is not working properly.

Monday, April 30, 2007

A trip to the thrift shop netted me a Panasonic SL-SX290. It's supposedly skip-proof. But it doesn't have a line-out, and its power plug is smaller than the others'.

Tuesday, May 1, 2007

A trip to Circuit City for a brand-new-for-real portable CD player was a waste of time. They're all the way in back, obviously no longer mainstream. No way to find out which blister-packed units might have Resume Play, and the PFY had never used such a thing, nor could he find out any information. When he wasn't looking I slit open the pack of a likely-looking suspect (Memorex) and slid out the instructions to read, but they were pretty unhelpful. I put them back and left, disgusted.

Wednesday, May 2, 2007

I went to Wal-Mart and had somewhat better luck. Still had to do the slit-and-slide trick, but the $25 Philips AX2411/17 I settled on looked like it had what I wanted: 4.5 V power jack, CD-R compatible, Resume Play, line-output, big buttons on the face. No MP3, but we don't need that. At home it seems to work fine, and Resume Play does function (though with a reset of the volume control output to a low level), but I could only test on batteries. I didn't have the right-sized adapter plug to see how it fared when running on external power. I think it'll be fine. Let's hope that the default reset volume level is appropriate for line-out (the single connector is marked both headhphones and line-out).

Thursday, May 3, 2007

I tested the Philips in the car. No, the default volume level is much too low, it has to be turned all the way up. Beep-beep-beep... Steaming piles of crap that these things all are. I'm not happy. Other than that it seemed to work all right.

Trying to find a player that meets all my criteria feels like Highlander, "There can be only one." Unless there isn't even that.

...After work I stopped by Radio Shack and bought a power plug.

Friday, May 4, 2007

Now that I have external power I tested the Philips on the bench. It worked. I made up another power cord, which was more difficult than expected. I had to do some filing on the one end's plastic 'bump', and then sleeve it with a piece of .22 shell casing! If only I'd known it wasn't really the right end I'd probably have cut it off and put on a better one. I thought it just had the extra plastic ridge as a retention device, but it turns out it didn't make good contact on the outside either, it was a bit loose. (Hence the sleeve.)

Anyway, with all the fooling around I ended up wrecking the power jack's switch, again, so I had to open up the radio and fix that. A lot of fiddly bending and prying. (I didn't have another jack.) When the smoke cleared everything was working again, but...

The Philips, while it does remember where it was, reverts to an unusable volume level every time you power-cycle it. POS. Also, there is an extreme amount of an intermittent farty noise coupled in from the motor, much more than any of the other four players I've tried so far. I'm thinking about returning this one, it's really not working out very well for our uses. I don't like the purely circular design, because it's never obvious where the buttons are on it. No 'front'.

I did notice that the Panasonic will remember which track it's on, but not where within that track. Better than nothing? It uses the same power plug as the Philips. However, it also has that wretched forget-the-loudness feature (pushbutton volume control rather than potentiometer), and as it's also missing a line-out jack it's not going to be any more satisfactory than the Philips. The cheap price of the thrift specials is a lot more palatable than the brand-new price of the Philips, given that none of them turn out to be what I want! (Even though they're non-returnable.)

I'm thinking I might just keep buying thrift shop specials until I get lucky. I can get a dozen or so for the price of that one Philips.

Tuesday, May 8, 2007

Ordered brake parts.

Returned the Philips to Wal-Mart. It cost too much for it to be anything other than completely satisfactory.

Wednesday, May 9, 2007

Trouble! My wife called me and said the car wouldn't start. (She'd just filled it up, too, it turns out. Four miles ago. Bad fuel?) After much fooling around I ended up with the key and over at the neighbor's where it sat. (Better that it acted up there than just about anyplace other than our own driveway.) Apparently it would crank OK, but not run. I pumped the (new-style) primer, which felt a bit 'airy' at first, and it started right up. As we prepared to caravan it home it started running rough and died. Weird. I pulled the primary fuel filter and it was very free. So was the secondary, we dumped it out and saw no sign of water or dirt. The contents looked, felt, and smelled like diesel. The aluminum washer and its seat look somewhat galled, though. Heavy-handed Hans may have had a whack at it at some point in time. I blew backwards into the fuel feed hose and that seemed to be OK. I pulled off the vacuum shutoff, no difference: it would start fine, but not run well after a bit. Sure seems like a cracked fuel line. As re-starting it was so repeatable I gambled and drove it home, I figured that if it died I could just prime it and get going again, limping home that way. It ran great in S, the only trouble it had was again at low RPM's at the house. I parked it and went inside, disgusted.

It could be, in no particular order:

I've got a new primer pump on the way that I ordered for the Frankenheap. I might try it in this car if it gets here soon enough. One of the fuel return lines is weeping, I'll replace that. I never thought the return system could cause this symptom, but it's certainly easy to try a fix.

...When my wife got home she sheepishly admitted that upon reflection, she'd put 15.5 gallons, $50, of gasoline into the car, not diesel! She was in a hurry and was worried about running out of fuel, so she'd gone to a different station than usual. She was positive she'd done this, remembers "87" on the pump (octane), and noticed that it didn't foam up like it usually did.

Yeah, that'll do it. That also explains the new-found 'stickiness' of the primer pump, and the extra 'fuminess' I experienced when blowing through the main fuel filter. The large reserve capacity in the tank explains why I didn't think there was anything particularly wrong with the fuel: the dilution wasn't quite so bad as to make it obviously gasoline, nor to keep it from running. It explains everything. Fortunately the fuel system in this class of car is extremely robust, it is unlikely that there has been any lasting damage done.

She admits that she didn't really want to tell me what she'd done, but I'm awfully glad she did. I don't know how much time and money I could have wasted trying to find what was wrong.

Tomorrow I need to siphon out enough of the tank so that the three gallons of diesel I have in cans here can push the gasoline dilution down to no more than Mercedes' old-time recommended limit of 25%. That should get me to the gas station where I can fill it up with diesel, pushing the dilution down to something tolerable. Over time I can then use up this contaminated fuel a little at a time, that should keep the dilution from being harmful while not wasting the $50.

Anybody need 20 gallons of custom 'injector cleaner'?

Thursday, May 10, 2007

One whiff of the fuel filler neck with a fresh nose and the smell of gasoline was obvious. Must remember to do this first in the future, before my sense of smell is dulled by getting fuel all over the place whilst messing with the fuel filters. I got out the siphon and all the spare gas cans. I managed to siphon out about 20 gallons then put in all the diesel I had on hand: about 3.5 gallons. We'll see. I also replaced the weeping piece of fuel return line, and the end plug which was also weeping a bit. (The gasoline seems to have exacerbated the leaks.) Both ends of the string got replaced, the inter-injector links are still OK which is good, as I'd just used up all the new hose I had left. (In the miscellaneous department I also put in 2 quarts of oil, I think it's burning some. I pumped up the tires, etc. Also put the recycling into the trunk, might as well do that while I'm out and about. Just the usual morning car routine.)

The car started fine but was a bit cranky at first and died once in the driveway, just as before, but by the time I got to the bottom of the hill it was back to normal. The 3.5 gallons was not enough to turn out the low fuel light. Fueling, including replacing the contents of the little cans, took 20.7 gallons, $60. That makes the contaminated fuel better than 3/4 gasoline. Maybe it'll run fine in the lawn mowers? We'll find some way to use it, that's for sure. The car is running perfectly well again. Looks like no harm, no foul.

I bought another two CD players at the thrift shop that's next to the fruit stand where I bought lunch. (They had about eight to choose from.) One has a dead drive motor, but the other one works fine. No anti-skip buffer, and it doesn't resume play. Oh well, I'll persevere!

Friday, May 11, 2007

When we got home from dinner out the sunroof wouldn't close. Stupid switch, I pulled it apart while parked in the driveway and managed to lose a piece (switch contact) down in the seat rail. Fortunately I had another switch in the garage. It, at least, worked properly. Also, the front passenger door check strap chose that moment to lock up again, it's been making some noise lately. I'll need to address that again. Not a good impression the car's been making lately.

The box of parts from Rusty came today, brake time!

Saturday, May 12, 2007

I dug the missing switch contact out from under the seat, cleaned things up, and reassembled the switch. It worked fine on the bench. Of course. It worked fine in the car too. We'll see if it hold up this time.

Unfortunately, after jacking up the car I found that the rear calipers were ATE, not Bendix. Oops! Wrong rebuild kits. (The fronts were Bendix, and I thought I remembered that the rears were as well. I guess I should have looked.) I put a set of the pads on the scraping side and put it back down. Will have to order the correct parts.

I opened the wonky passenger door and it wouldn't close again, no matter the coaxing. So I opened up the door panel and removed the door check. It looked OK, but wouldn't move properly. Messing around with it blew out the side of the slider. It's dead, Jim. I dug out the spare check strap, it's one of the old pot metal ones, but intact. Put it all back together. Works fine again.

Friday, May 18, 2007

Happy volcano day! I ordered the correct rear brake rebuild kits, and some more fuel return hose to replenish my stock.

Tuesday, May 22, 2007

Filled up today, I put in 2.5 gallons of 'Jill's Custom Injector Cleaner'. The car ran fine, you can't tell that there's 2 gallons of gasoline mixed in the tank. We'll be able to burn this stuff up this summer.

The tiller was empty, so I put some of the crud in it, too. It ran OK, but seemed a bit weak (though usable) and needed the choke on halfway to run smoothly. If we can use it up this way too we should be able to get rid of this stuff fairly quickly.

Thursday, May 24, 2007

I got out the replacement Becker 599. It worked fine, both channels, both bands. I removed the modified Becker from the car and compared the wiring of the volume control boards. No, it's OK. So I pulled the modifications out of it and transferred them to the replacement. That went fairly easily, I'm glad I made it to come back out again. While I was in there I put in an additional power supply filter to the external power jack. I dug a 2.25 mH torroidal choke and a 1 µF capacitor out of the junkbox and ran the power lead to the jack through them. I think it has helped some in cutting down on the motor noise from the CD player. I modified the schematic to match. Oh, and the replacement Becker came with the missing tone control knob and matching filler plate for putting behind the tuning knob. Between the two of them I now have a full set of the cosmetics. (And an extra knob.) Beauteous!

Another thrift-shop special, a Sony Discman of some sort, induced hideous amounts of chirping, shrieking motor noise into the audio chain. The worst yet, even with the new power filtering. We keep looking...

Friday, May 25, 2007

Just wanted to note that the sunroof switch is still working properly. Usually it didn't hold up this long. Perhaps it's finally fixed for awhile? It is also time to note that the intermittent reverse-lamp fuse-blowing behavior seems to be entirely gone, so I guess it was the neutral safety switch after all. We shall call the surgery successful.

Tuesday, May 29, 2007

The remaining brake parts came. I also want to note that the replacement Becker seems to sound especially 'tinny'. Not sure what's up with that, if anything. Other than that it's working well enough. The sunroof switch is starting to get cranky again. Sigh.

Wednesday, May 30, 2007

It's starting to warm up. When will I find time to recharge the AC? Has to be warm out to do it right, so mornings (my usual car time) are not a good choice.

Thursday, May 31, 2007

Brake day! I used the brake pedal to force out the frozen puck. As always, removing the second puck from the caliper is the hard part. I finally fabricated a seal/clamp out of a big washer with a circle of inner tube rubber glued to it, and two 7×2×3/8" strips of heavy metal plate to clamp it in place. I had to notch one of the plates to fit around the grease gun's pipe. With two C-clamps I could then clamp the seal into place yet still leave enough room for the other puck to come out. It just walked right out using water pressure from the grease gun. I have thought about fabricating this clamp every time I've had to do this miserable job, I finally got around to doing it! (I need to get a big bolt so that I only need one C-clamp for this operation in future.)

With the sticky caliper all apart I got all the rust sanded out of the bores (outside the seal) so the pucks would slide easily again. (600 grit wet-and-dry under running water in the sink.) They now fit nicely into their bores and will slip out under their own weight. The rubber parts were actually in fairly good shape. I'll still replace them with the kits', but I will keep the old rubber for jalopy use. I blew everything dry to prevent rust and set it aside for tomorrow. A little WD-40 went into the clamps' Acme screws and the grease gun's guts. (Water displacement [WD: trial formula 40] is what it's actually for!)

I may want to paint the parts of the caliper where the rubber boots clip on. Perhaps they will seal better keeping it drier inside and helping to prevent further rust?

Tool fabrication took a lot of time so I was unable to finish the job; I had to take the truck (with camper) to work. Perhaps tomorrow. I did squirt PB Blaster on the hose fittings to let it work overnight.

Friday, June 1, 2007

More brakes. I spray-painted the caliper black, taking some care not to get paint inside the bores, and put it in the shop oven to dry. I then removed the other caliper and rebuilt it as well. I used a Dremel wire brush to clean out the grooves in the pucks, as well as the seats for the boots. Experience and having the right tools really makes it go quicker. I also gave it a blast of paint and put it in the oven.

The master cylinder came off easily, and once it was off I stuck a plastic tube (from my topside oil sucker) down in the booster to the bottom and sucked on the other end. A lot of nasty-looking fluid came out! It was definitely time to replace the master cylinder. I washed off the booster and blew it dry, then rattle-canned it black. There was a lot of paint gone because of the brake fluid leak. I then installed the new master cylinder and transferred the reservoir to it.

The calipers went back together easily. The big secret is to put the boots on the pucks before they go into the bores, otherwise it's a lot harder. Brake fluid is used as an assembly lubricant. I don't know if the orientation of the asymmetrical face of each puck is significant. I could find no information about this, so I didn't try to line them up with anything in particular. The calipers went back on the car, and the hoses were replaced. The PB had presumably done its job, the old ones came off easily.

Finally I enlisted my wife's help to bleed the brakes, which went smoothly. I then cleaned up the mess.

...Driving to work the brakes worked very well. No more squeaking and scratching noises, and braking power was even and good. Nice. At lunch I stopped at Schuck's and NAPA, but neither had the little rubber covers for brake bleeder screws. I'll liberate some more next time I go to the U-Pull, I'm missing three. It was hot out today, time to work on the AC! (It needs a charge.)

Saturday, June 2, 2007

I jacked up the front of the car. I then wire brushed off the brake-fluid-damaged paint areas and rattle-canned black paint on there. I even had some medium blue that I used to hit the bodywork below the brake booster. I found a can of spray-on undercoating, so once the paint had dried I put that on the bottom surfaces. I did a bit of chipping at the undercoating on the rocker panel, and it was good. One small loose spot I removed and treated as above. No sign of rust in the rocker panels, or anywhere else underneath. The body brace behind the driver's brake strut was loose so I tightened that. I vacuumed out the crevices in the hood hinge areas.

I then checked steering linkages. All seemed tight, yet I could still wobble the wheels a bit more than I liked. I backed out the adjusting nut on the steering box 3/4 turn, about half of what I could back it out using only my fingers. (Which was definitely too far.) It's not really much tighter, but we'll see how it behaves. I don't think I went too far, but we'll see. If there's a 'notch' in the steering around center I'll know I definitely went too far and will have to put it back some. The steering box may be worn out, or I (working alone) may have missed something loose beneath.

I next drained the tranny fluid. I enlisted my 5-year-old son's aid to lie under the car on the creeper and tell me when the torque converter drain plug showed up in the access window while I rolled the car over via the power steering nut. Slick. I dropped the pan and found it pretty clean inside. The fluid in the pan was a bit murky, but not bad. Stinky, too, like mothballs. Fresh fluid smells more fishy to me. I removed the filter and put the new one on. (There's no way you can do this job without getting oil all over the place, no matter how careful you are.) I washed off the pan, and scraped off the grime on the outside. I mopped it dry and wiped it out with my hands to remove all lint and grit, and set it in the sun to finish drying. I put on a new gasket, wiped off the pan gasket surface on the bottom of the tranny, and reinstalled the pan. I then poured in three quarts of fresh fluid, started the car, and poured in another three and a half. No leaks appeared during this.

I took the car for a quick test drive and it drove normally. The transmission shifted as before. Sadly, there was no miracle cure. The steering seemed a bit tighter, and I don't think I've taken it too far. We then broke for a late breakfast. (My boy was still hanging about.)

In the heat of the day (80's) it was time again to charge the AC for the year. I put on the gauges (why, oh why, is that stupid high-side fitting on the bottom of the car?) and found there was still some residual charge, so there was no need to vacuum the system. I put in a can of Isopro, AC on, and then followed it up with a slow propane leak until the gauges looked right. Some time during this the auxiliary fan started up with a roar. Looks good. I put a mister on the condensor and got in and revved the engine to 2000 RPM . The vent temp gradually dropped to 45 °F, which is about as good as you can get in this car. I buttoned things up, and tightened the Schrader valves a bit before putting on the caps. The high side valve seemed a bit loose, perhaps that's where the last charge went. On a short test drive the vent temps got down to 47 °F which is OK. Not as good as the 38 °F that I'd gotten once, but tolerable. The AC seems to cycle on and off yet the vent temps aren't at their lowest. Probably the pressure (charge volume), or perhaps the gas ratio, is off a bit. If it's overcharged that should self-correct through the season.

With all this done the scheduled operations for this car (this year, anyway) are done. Now we'll just drive it, and I'll try to work on something else. Until something breaks!

Monday, June 4, 2007

That didn't take long. We drove to band in this car and the AC kept cutting out, especially on bumps. I'd suspect the blower brushes, except that I could hear a definite click behind the control panel each time it cut in or out, and cycling the switches would bring it back. I think it needs some more resoldering and/or contact cleaning. I suppose it could be fuse related as well, I'll check that too. (OK, I think it has had this problem for awhile, but it was less noticeable in the heating season.)

Other than that, and its current cosmetic challenges, the car is sweet. Purrs down the road like a kitten. It is shifting better than it was, at least a bit, and the steering feels better. The brakes are now unremarkable. That is, you no longer notice anything, it just stops like it should.

Tuesday, June 5, 2007

Another thrift-shop CD player. Had a Resume switch on the side, so it might be what we need...

No, it doesn't really work, and takes a long time to sync up to a track. Bad laser?

Wednesday, June 6, 2007

I removed the ACC panel. After I opened it up I could see that some of the joints on the switches were crystallized, a few didn't look like I'd ever worked on them. I recall now that the joints to the side boards had been broken when I got the car and that is what I spent the most time on. They still look good. I dug out the hot iron and attacked the troublesome joints on the main PCB. It takes a lot of heat to do some of the relay pins, and I've had trouble using my regular iron for this before. That's why I have an extra-hot iron, for the hard cases. Anyway, it went well enough, after which I shot contact cleaner into the switches and worked them. I then put the panel back in the car. We'll see how it works.

...On the way to and from work today the heater worked perfectly. (We're having a cold snap, no AC this week!) It's a little early to tell if the problem is fixed, but it's certainly a good sign. I know that the heater occasionally needed a jump-start by turning on and off the AC, yet the cold engine lockout switch tested good. It didn't need any such help today.

Friday, June 8, 2007

Just wanted to note that the ACC seems to be behaving itself. Haven't needed the AC lately, however, just heat.

Friday, June 28, 2007

Locked the car in the morning as we were going on vacation. (It hadn't run since yesterday.) All the locks operated, naturally.

Monday, July 9, 2007

Unlocked the car to go to work after the vacation was over. All the locks operated, the vacuum system is thus good for more than a week. Good. I should also note that the tranny is shifting better than ever, even the 3–4 flare is improved. We may have staved off the bad tranny wolf for a bit. Also good.

Sunday, July 22, 2007

The odometer has finally stopped, this is a common malady with these cars. Supposedly a drop of cyanoacrylate glue on the shaft will fix it, naturally getting to the right place is the hard part of the job.

Monday, July 23, 2007

I removed the failing odometer from the car. I looked at putting cyanoacrylate glue on the shaft, and even tried a bit, but it didn't want to wick into where it needed to be and tried to sieze the shaft where it goes through the frame. Things are just too tight there for the 'quick fix', I don't know how anybody does it without ruining the odometer. Time for Plan B. I removed the face of the speedometer, first lifting the needle over the zero stop and ensuring that it rested on the little mark on the edge of the dial that marks its zero tension position. I then used the two-spoons trick to pop off the needle. Next I removed the odometer drive shaft entirely, liberating all the plastic dials. The pot-metal drive gear (in the non-visible tenths position) was really quite loose, but sometimes would bind a bit. Looking inside the bore of this gear it appears that there might be a bit of spring wire coiled in there that is supposed to 'bite' on the shaft. Anyway, I knurled the shaft where the metal drive gear seats using a pair of pliers. One must be very careful not to mar the shaft where the plastic dial gears are as they must spin freely. While it was apart I used alcohol and a swab to clean all the dial faces, the trip odometer was particularly filthy. I then reassembled the shaft and dials, which was not easy. It took a few tries before I got everything aligned so that it would function and the dials lined up through the holes in the face. I added some miles to its reading to partially compensate for the (short) time that it was broken. I had to tap the shaft into its final position with a hammer as the knurling made for a tight fit. After it was all together it worked freely when driven by my thumb. I then reinstalled the speedometer face, put the needle on the shaft so that it pointed at the resting mark, then lifted it back over the zero stop. I then greased the drive gears and put some M1 5W20 on the sleeve bearing. With this all done I reassembled the instrument cluster and installed it back in the car. I also squirted a bunch of oil down the drive cable. We'll see how it goes!

Regarding the apocryphal warning against resetting the trip odometer while moving, having just become intimately familiar with the guts of the offending unit I can in no way see how resetting the trip odometer, moving or not, can place any significantly greater torque on the drive gear. If it does, the amount is nearly trivial and the drive gear is already about to fail. It takes considerable torque to roll over a bunch of dials at once, that drive gear is supposed to be tight.

...and it works. Good.

I found an interesting link involving slipping shifts for these transmissions: Here

Saturday, September 22, 2007

Road trip! To Yakima and back, its home before ours. Car worked well, but the cruise control didn't want to resume. That's because the switch hits the back of the steering wheel! I wonder why that is?

There was a weird little intermittent screechy scraping from the left rear of the car while returning home on the freeway. I will have to keep an eye on this just in case it wasn't a small rock trapped in there.

Monday, December 3, 2007

The passenger door check is 'grunching', so I took it apart to grease it. Oops! Wasn't the (old-style) check at all, in fact it was the side trim of the door rubbing on the fender. Old-style checks aren't prone to seizing, anyway. I greased the thing since I had it apart, and the hinges as well. Grease on the offending molding stopped the noise.

Friday, December 7, 2007

After many complaints from my wife, and some goading from successful examples on the mailing list, I removed the instrument cluster, pried off the light pipe covers, and lined the pipes and the lamp compartment with aluminum foil. Dabs of Shoe Goo hold the pipe covers back on. I put the cluster back into the car, but didn't push it back into the hole yet. No way I want to there to be any chance at all of gluing the cluster into the car!

Sunday, December 9, 2007

Jill's been complaining about the car driving 'wonky', and the last time I drove it I thought there might be something wrong with the front left tire, so I'd jacked it up and give it a spun, but noticed nothing wrong.

Well, today I followed her home, and OMFG, the left rear definitely has a problem. Even Daniel could see it, and he's no car expert! When we got home I took it off, and there's something like a 1/2" bend in the tire, the tread's now in a serpentine course. Shot to hell. These tires are the original Michelin Arctic Alpins that came on it five years ago (and they weren't new then), but they're pretty much worn out anyway. They're 195/70R14's, but we got a set of studded 205/70R14 Hankook tires (no wheels) with the 380 SL that should serve. Relatively few miles on them, the tread looks very good. I removed the bad wheel and put on a spare that I had on a bundt rim to get her through today, I'll send the load of Hankooks with her in the trunk to have put on at the next opportunity.

This evening she reports that the wonkiness (tire wobble) is all gone, and that the dash lights are almost tolerable in brightness.

Monday, December 10, 2007

Hankookified!

Tuesday, December 11, 2007

Jill asked me today if the car wasn't supposed to have a piece of molding on the driver's door. "Why yes, it should." Apparently the thing fell off somewhere in the last day or two. All but one of the round retaining clips are gone from the door, the one left is near the back. Probably there were two left, and when the (front) one fell out or broke the whole thing stripped away.

Crap.

Thursday, December 13, 2007

Jill found the missing trim in the driveway today. Looks to me like it got run over once, but is probably still usable. Oddly, it didn't have the stock red plastic retainers, it had some weird metal clips. That's why it fell off, no doubt.

She also reports that the car only got something like half the normal mileage this last tank. I've been smelling a bit of diesel around her car lately, I guess there's a leak. I popped the hood when we made the son exchange today, and I could see that the line from the fuel pump up to the filter was wet. This could be just the line, or perhaps the (new-style) primer pump could be leaking. A couple of the return lines are also wet.

Friday, December 14, 2007

I replaced two pieces of large fuel line, and three sections of the skinny return line. The large was generic McParts, but the skinny stuff was official. With any luck...

I also filled the washer tank with some mixed-up 20/20 and a shot of isopropyl alcohol, and topped up the engine oil.

Tuesday, December 18, 2007

I finally got a chance myself to drive the car at night, and the instrument lights are indeed brighter. One can actually read the odometers at night now.

Thursday, December 20, 2007

I finally had some time to take a look at the mashed trim strip. The old nasty incorrect metal retaining clips pulled easily off the trim's bumps, all the bumps looked good. I dug in my junk box to find six of the correct red plastic retainers (used), and snapped them into the car's door. The trim then just snapped into place. Looks a little wonky, but better than it did without trim at all. I'll have to keep an eye open for a better used strip at the junkyard.

Saturday, December 22, 2007

On a trip back to Yakima Jill was driving (and thus had control of the heat), and I was baking. When we swapped it turns out that there is a small cold draft in the footwell of the driver's side, which is missing the underdash panel. (I'd taken it off for access years ago.) I'll have to do something about that. The steering is a bit loose and darty too, which is not normal for this car.

Sunday, December 23, 2007

On the trip back from Yakima I found that the engine was squealing a bit as we got home. I checked the belts, and found the alternator was very loose. I hand-tightened it which restored the belts to a more normal tension, but it squealed even worse on a short trip after that. I need to tackle it more properly tomorrow.

Monday, December 24, 2007

I tightened the alternator belt some more and the squeal seems to have gone away. We'll see. Since I was there, and it was sunny out, I dug out the missing under-dash panel, which took some finding. (It turns out I had stored it in the trunk of the 250C.) The staples holding the two halves together had failed, so I pried them out and glued the two pieces back together, clamped them, and set them aside to dry. I also jacked up the front end of the car to have a look, and it appears that the idler arm might be a bit loose. The steering damper is also not what it should be, so I'll need to order those two (wear) parts. The ball joints and tie rods all seemed fine. The steering box may need replacement, I think it may have too much play in it. I already adjusted it once in June.

...This evening the driver's lock felt weird when I locked it at church. (And isn't that necessity an indictment of modern times!) When I got back out I couldn't turn the key. At least I'd repaired (long ago) the passenger door keylock, and could get in that side. I don't think it's just frozen, but we'll see tomorrow.

Tuesday, December 25, 2007

I installed the under-dash panel. (It was surprisingly difficult to get that thing back into place, which I think I recall from working with it before.) That should (I hope) stop the draft. Merry Christmas, honey.

The door lock works again. I think it was just frozen. I also think it could use some lubrication.

Thursday, December 27, 2007

I wrapped a bit of duct tape around the torn speedometer cable boot. Could that have been the original source of the draft?

Friday, December 28, 2007

Jill finally drove the car again. She didn't have too much to say about the draft thing (it's early days, after all), but did comment on its quieter nature.

I also ordered the steering damper and idler arm kit.

Tuesday, January 1, 2008

The car hadn't been driven for a few days, and again it started rough then died, and required much cranking to get going again. It may be that we have an air leak in the fuel system causing loss of prime.

Monday, January 7, 2008

The steering parts came today. Jill managed to get to the box on the porch before the dog did.

She also took the time to point out to me that she hates the iPod-ified radio, always has, and wants a plain in-dash CD player. Oh well.

Tuesday, January 8, 2008

No time for installation, but I did put the steering parts in the trunk. Whee.

Friday, January 11, 2008

I installed the new steering damper and the idler arm kit. Jill reports that she has noticed nothing, it may be that there is no material improvement. After installation I didn't think the new idler arm kit made any difference in 'slop', so I saved the old parts for jalopy use. I probably need to replace the steering box if I want to actually tighten things up any more.

Sunday, January 13, 2008

Driving the car I can definitely detect that the steering is more damped than before. Not tighter, but not sloppy-loose. Still a huge contrast with the very tight steering of the Frankenheap. (Which may indeed only have 50kmi on it as its odometer indicates. Its steering is tight, and its engine starts readily in the winter. On the other hand, it's not power steering so that is probably inherently tighter.) Still thinking about that spare steering box in Smelly (the 300D parts car in the woods). Don't know what kind of shape it's in, however.

Sunday, January 20, 2008

Seattle road trip. A few thoughts come to mind. One is that the car might need a new thermostat, it was quite cold out and the engine temperature was a little bit low, and cabin heat was approaching marginal at times. There is still a draft in the driver's footwell, now it's leaking out from behind the panel at the parking brake. Not as bad as before, but not optimal. Weather in the teens is bringing out the problems, naturally. The steering is too loose. I need to pursue a replacement steering box. Perhaps they just don't make it to 300kmi? Mileage was sub-par, about 23 but verging on 25 on one short easy leg. No obvious fuel leaks or dragging brakes to blame it on. The RR door check is starting to bind, I need to take care of that pronto. Other than that, and the ratty windshield and poor wiper blades, the car behaved pretty well.

Hmm, I guess this doesn't add up all that well after all. Most of it is fairly straightforward to address, but there's a few stinkers in there.

Saturday, February 16, 2008

I opened up the RR door. The replacement (used) check strap still looked OK, but the grease had dried out in the track and there was some corrosion starting up. I put it in the solvent tank while I had breakfast.

I then took it apart and cleaned off all the grease and dirt, and found that one of the two large BB's was getting rough and corroded. I put it in the angle of one of the welding magnets and brought it to the wire wheel, and with some brushing and spinning I got it much smoother. I then sanded off the tracks in the solvent tank, dried everything off, and greased it all up. Getting it back together was (as always) a real joy. It didn't go too badly, I used a woodworking bar clamp to compress the BB's into the slider with it nearly in starting position on the track, and then used a heavy iron bar and the BFH to drive it into the track.

I put it into the door and tried it out. Not as smooth as new but tolerable. I then reassembled the door, everything works fine now.

Sunday, February 17, 2008

My wife's taking a road trip today. So I prepped the car. Changed the oil, first time in (OMFG) 17kmi! Last record I have is sometime in '02, though the ATF and filter has been changed twice in that time. Somehow this one got away from me, imagine that. It came out kind of sludgy, even though warmed by a long idle. Delo may be good oil, but it's not that good!

I didn't even get to change the filter, turns out I don't have one. Boxes of 60x filters, no 61x filters at all. I think I bought one, and that's what I used in '02. Next time. I'll do a short service for this batch, call it a sludge-removal stage, then change both oil and filter. Stupid.

Oh, and Jill pointed out a cut in the driver's seat belt, it probably got slammed in the door latch. I'll get a replacement next time I find a 123 in the junkyard.

Wednesday, March 12, 2008

Jill reports that the car's transmission slips sometimes when cold. Theorizing that the small ATF leak is to blame, I poured in half a quart that I had in the trunk. We'll see.

Tuesday, March 18, 2008

I put the car down below, now that Jill's driving the 190D. It's time to stop driving with studded snow tires, anyway.

Friday, November 28, 2008

Snow car day. I put the battery charger on the car after I got the Frankenheap going, and it drew a heavy charge. (It needs a battery cutoff switch too.) After it had charged a while I tried to start it, but nothing doing. It would cough a little bit, but not run. I tried priming the fuel system, and nothing. I tried several times, but I don't think I was waiting long enough. I even stole the boat's battery (which I'd been meaning to bring inside anyway) and used jumper cables to tie it to the car's battery, but nothing doing. With the extra battery's help I did get it to run once, but it died after a few seconds. I cracked the fuel bolt and primed, a lot of air kept coming out. I wonder if I've got an air leak in the fuel system? I decided to let it charge overnight before trying again. It's a drag because I threw all the Christmas decorations in the car to haul it up top, and now it'll have to wait as I don't want to unload it all and bring it up by hand in the slippery snow.

Saturday, November 29, 2008

The first crank-fest didn't work, so I primed it again. This time I could feel and hear it 'take', and when I tried starting it again it started, no problem. I was able to run it up the hill in spite of the snow, I left it idling to warm and dry out the interior while I unloaded the car and put the lights and decorations on the garage.

Saturday, January 31, 2009

I readjusted the headlights, they were a bit wonky. I tried the fogs, and it blew the fuse immediately on the passenger side, taking the low beam with it. Great, more work!

Sunday, February 1, 2009

The problem was that the fuse had corroded and stopped making good contact, but it didn't blow. I replaced it with another, and the lights worked again. I also burnished the contacts in the fuse box.

Monday, February 16, 2009

I stopped by the U-Pull today, and got a driver's seat belt from an older 123. I hope it fits, I've been looking for a year. I also got a pair of tire chains, Jill will feel more comfortable with them in the trunk of her winter car.

Tuesday, February 17, 2009

I checked the seat belt, and it fits. I used vise grips to keep the belt extended from its roller. I then washed the belt out in the sink and hung it to dry in front of the fire while I removed the old belt. (They roll a lot easier when they're clean and supple, rather than all dirty and stiff.) Installation was fairly uneventful, I left the belt out and buckled to the other seat to facilitate drying.

I also noticed that the center belt in the rear has a nick in it, and the passenger-side rear belt's plastic handle is broken. Today?

...At the U-Pull today I picked up the two seat belts. I had to get the driver's-side rear belt, but it should swap OK if I just turn over the buckle on the belt. I also got the driver's-side door molding to replace the one that got driven over last December.

...In the evening I washed out the two new belts and hung them in front of the fire to dry overnight. They were filthy! While the one belt was all nice and wet and slippery I turned it over in the buckle, so it should fit into place tomorrow on the opposite side of the car.

Wednesday, February 18, 2009

I removed the rear seats of the car, opened up the C-pillar cover and removed the one seat belt with the broken plastic on the buckle. (I found a mouse nest inside the rear seat back, how nice!) The new belt went into place fairly easily, though it doesn't have the anti-twist plastic guide behind the shoulder mount point that the newer ones have. The new center belt turned out to be sufficiently different that I couldn't use it, the original shared a mount point with the receiver for the side belt, the proposed replacement did not and was an individual piece. So I left the nicked center belt in place. The side plastic C-pillar cover is all buggered up, which is no surprise as that whole rear area is a mess. Somebody who worked on it previously was a hack.

Monday, March 9, 2009

I jacked up the LF end of the car and checked the suspension and brake, Jill has mentioned a 'clunking' when braking (which I haven't noticed when I've driven the car). Nothing wrong that I could see/feel.

I then added some ATF, because I have noticed some slipping at times. The dipstick (cold) showed low again, so I felt fairly safe here. I also refilled the washer tank and topped off the radiator with a little water, it was a bit low. I wonder when I last serviced the cooling system on this car? 'tis a pity I didn't start keeping good records earlier.

Saturday, March 14, 2009

Preparing for yet another trip in the Yakamobile I found that the AC belt was broken and chewed up. The compressor hub doesn't seem to be seized, so I'm not too sure why this happened. I'll look into this sometime later.

Saturday, March 28, 2009

I removed the rock-pipped and wet driver's-side fog light and cleaned it out. (This necessitated removing the light's rear lamp fitting, which is tricky to remove from the glass and metal shell—you have to bend back three bent ears that hold it on.) I then used clear 5-minute epoxy to fill the crater. (The original glass bits were too shattered to restore.) In five minutes (?) it was dry enough to reassemble and put back. Now this one matches the other side, which also had a big rock pip in it. Though the epoxy yellows with age, on these yellow fog lights that's not a problem at all.

Wednesday, April 1, 2009

Today at the U-Pull I was shopping for parts for the 560 SEL and found that the 123 they had in still had one of the little plastic screw covers for the knee bolster, this will fill the one remaining hole in our dash. Yay! I also got another rear center seat belt, this one is a double-header like the bad one. I got a 190E's dome light, which looks a lot like the 123's except with an auxiliary reading lamp. Maybe it can be adapted, the switch on this car's light is getting really flakey. I also found about $2.25 under the rear seat, including the first-ever bill I've ever found in such a place, so that paid my way in. I noticed that the steering box on the donor is tight, I should come back Saturday and get it, the one on this car sucks.

Saturday, April 4, 2009

I went to the U-Pull and got the steering box. This went fairly well, though it's a surprisingly expensive part ($22), and they charge extra for the Pittman arm ($13). (Like you can actually remove one of those with any ease.) I also picked up the glow plug relay, engine-side wiring harness for same, and the three pencil-style glow plugs left on the engine. A veritable bargain: $3 for all that—the price of a relay. I was there less than two hours, and that included browsing around the other cars.

At home I got the car jacked up before we had to go off for dinner. I'd hoped to get further along, but no...

Sunday, April 5, 2009

I started removing the steering box. I cracked loose every bolt before beginning to remove everything. It was all pretty uneventful, practicing yesterday certainly helped. (The puller I'd made for these joints works excellently. Some pressure and a few hammer taps and POP! Off it comes.) The tie rod ball joint had a torn boot, though it hadn't worn loose yet due to dirt getting in, so I pulled off the boot and cleaned it off and out with brake cleaner. I used cyanoacrylate glue to tack the boot's tear together, then potted it in Shoe Goo for strength and set it in front of the fireplace to dry while I proceeded. I got the steering box out, that went easily enough. When removed I could see some frame rust underneath it, so I brushed it off and hit it with some black paint. Trying to put back the new steering box was difficult. It was too heavy for me to push up from below, not from the angle I could reach, and even if I could I couldn't see to attach it to the steering shaft. Instead I tied a string around its shaft and ran it through a hook in the ceiling, and lifted it up to almost the right height and tied it off. Then I could use both hands from above to try to finesse the thing into position. Once I spread the retaining collar with a screwdriver and a hammer the thing then went on, and reassembly was uneventful. I cleaned out the one dirty ball joint and pushed grease into it, then slipped on the repaired boot. That should help keep it good for a few more years.

I then filled up the reservoir and took it on the road. It was much better, but still not as good as our other cars. So I began tightening the adjustment screw (CCW!) fractionally and then driving again. You do not want to go too far! I think I ended up about 1/4–1/3 turn by the time I decided I'd gone far enough, over about six tries. The car drives infinitely better than it did before, so I'll call the whole thing a success. I did have an oil leak on the low-pressure line, so I tightened that some more. We'll see if I got it, I may need to take it off and clean up something if it keeps oozing. I have a spare hose that came with the new steering box if I should end up needing it. (I kept the hoses on the donor box to keep dirt out of the guts at the junkyard.)

I'd say that's $35 well-spent.

Tuesday, April 7, 2009

Today I drove the 380 SL, and it said 75 °F on the bank sign. Hard to believe that we had maybe 4" of snowfall not even a week ago. I think I can now swap Jill to another car safely. I put the car down below and disconnected the battery for the summer.

Sunday, November 21, 2010

Got the car out for the Winter. (Long past time to switch cars! The 560 SEL is not yet ready to go.) It was sub-freezing today, and snowing, but starting was not an issue. With the battery reconnected, the tires pumped up, and a battery charger connected for a bit the car started immediately. No problems. I ran it up top and plugged in a space heater to fully dry it out.

Wednesday, November 24, 2010

0 °F this morning, and the car wouldn't start for Jill when she went to leave at about 10AM. (It hadn't been plugged in.) The battery wasn't up to trying more than once. It got it plugged in before we left, and when I got home from work I put on the battery charger, and after 15 minutes I started it without any difficulty. I left the charger on overnight, too.

Thursday, December 16, 2010

The rear dome light wasn't coming on, and it wasn't the fuse. When I pulled the fixture the bulb was good, but it had corroded a bit and wasn't making good contact anymore. Easily rectified.

Friday, December 17, 2010

Again with the rear dome light. I scraped it better this time, we'll see if it holds. I found a front dome light assembly, with auxiliary map light, in the glove box that I'd obviously procured at some time. I disassembled it and cleaned the contacts, and used a little light lithium grease on the thumbwheel pivot and detents. It works nicely, and worked well when installed.

Saturday, January 1, 2011

The car has acquitted itself well the last week we've been on vacation. It rolled over 300kmi early in the trip, runs like a top. This morning we were back on the East side, in Yakima which was actually a bit warmer than what I later found here at home, and temps were colder than we'd been experiencing up 'til then. It was in the teens this morning when I went to start. Two full glow cycles and it still didn't go. Another two and the battery was getting weak, but I kept on the starter and it finally started firing. After a bit it was running, died once, and I laid on it again until it was running. Then it was fine, I left it idling to thaw out and recharge the battery. It really wants to be plugged in under such conditions! I'd say we put on about 1000 miles this trip. We got 23–25 MPG.

Monday, January 17, 2011

Ordered a new ($12!) windshield washer splitter/check valve, MB P/N 000 860 08 62, the old one has blown apart and is leaking badly. The tie wrap holding it together isn't really doing the job.

Thursday, January 20, 2011

Today at the junkyard I got a replacement washer splitter. It's more fitting to put used parts on this car than new, where practical.

Saturday, January 22, 2011

I installed the used washer splitter. The new one that came yesterday can stay in the parts reserve. [Since used in the 190D.]

Sunday, March 13, 2011

Jill called from the gas station and said she couldn't get the key out of the ignition. I went and found that the lock cylinder appeared to be 'caught', and with a lot of jiggling I freed it. It wouldn't cycle to 'unlock', and the ignition lockout prevented it from starting again. I think it's time to order a new ignition cylinder with key. (The one that was in there when I got the car was cut up, probably due to a sticking incident, and I transferred its brass locking wafers to a different cylinder from a parts car. At the time I didn't want to invest in an unknown car, but the car has been reliable enough that it's worth a bit of investment now. Also, a spare key would be nice to have.)

Tuesday, March 22, 2011

New license plates, 'required'. The State has found a new revenue source...

Last night on our trip to a concert the sunroof was dripping on my tuxedo. At least I was the passenger and could fend it off. This morning it wasn't raining so I opened the sunroof and checked the front corner drains. (It was cold and the roof was sluggish, but operated correctly nonetheless.) I slipped a windshield wiper blade spine down into the front drain channels, and when I blew compressed air into them I could hear it coming out by the wheel wells. There was a piece of rubber seal about 4" long that was loose underneath the windbreak support rail on the dripping side. No sign of where it should have come from, nor one on the other side, so I removed it on the theory that it could have been impeding water flow and causing it to spill up over the rail when braking. I blew air backwards to the rear drains, but couldn't hear anything. We'll see if this little operation has helped any, the rains are due to continue for awhile.

Saturday, April 2, 2011

The rear dome light still wasn't coming on, that was really puzzling. I'd had it apart for cleaning several times, and it's a different bulb too. I took it out of the car and checked the power plug with a test light, there was power. But the bulb showed no continuity on the bench, yet looked fine. I fiddled with it and one of the end caps came off in my hand! The end wire had corroded in half, and since I didn't have another bulb readily available I scraped the nub and soldered another wire to it and soldered that into the end cap's hole. It worked again, and next time I'll know just what to do. (Replace the damned bulb!)

Windshield glass replacement is imminent, I scoured the garages for the windshield seal I'd bought years ago and couldn't find it. Very distressing! (Though not all that surprising...)

Wednesday, April 6, 2011

Windshield day! The guy showed up and we moved the car into the garage and out of the wind/rain. He brought new Pilkington glass and a Precision (brand) gasket. The new gasket looked good: heavy dense material, formed corners, etc. The new glass looked good: no waves that I could detect. The old gasket was cut out and the trim and glass were removed. No rust was seen under the gasket, it looked quite good to me. He stretched out the gasket and fit it to the frame first, then he pulled it off and put it on the glass. Glass cleaner was used as lubricant, as required. Then he wrapped a 1/4" cotton (?) cord around the outer channel, 1 wrap. Then he put on the glass and roped it in. He took his time, and there was a lot of fiddling, pushing/pulling with the aid of a big rubber suction cup, slapping of hands on glass, kneading of the gasket, work with various picks and plastic wedges. A gigantic PITA, and we're leaving out all of the false starts. Voila, after about two hours the glass was in, but the locking trim was not. I had to go. Apparently shortly thereafter he did too, but came back in late afternoon to finish. While trying to put in the trim he broke the windshield, three cracks from top to bottom, nearly in the center! He left in disgust, no charge. Trim still not on the car. Not sure what the next step is, or should be. He put in maybe four hours, a new gasket, and new glass. We put in nothing but the heat and light in the garage. So far. (We do have a new gasket and no pitting, but it's still broken and the trim is out.)

I think I'm glad I didn't try this myself. (If I had I'd have done what worked for the Chevy: trim in the rubber before it goes into the car. OTOH I broke that glass too, but at least the trim was on.)

Friday, April 15, 2011

Jill started off on a road-trip halfway across the state today, and called because the car was shrieking at her. Very displeased she headed back home whereupon I tightened the alternator belt, which had (somehow) gotten just about as loose as it could be. Odd.

Monday, April 18, 2011

Jill's back, and said that for the last few miles it was starting to chirp again. I checked, and the belts were completely loose again. Whatever's supposed to hold the belt adjustment in place is not doing so, I'll have to look into that. I tightened it up again, it'll hold for a bit anyway.

...And a bit was only one morning. It was shrieking again at lunch time, and was completely loose. I tightened it, went to the auto parts store, and procured some blue Locktite to douse it with. We'll see if that holds.

Tuesday, April 19, 2011

From the mailing list: "There are 3 bolts that have to be loosened." I looked closer, and he's right. The top bolt had a 17mm nut that has disappeared. I replaced it with one from the junk box, with lock washer, and tightened it. That should help immensely. I see in this log that there was an earlier episode of belt squealing, I think the nut has been missing for at least this long, perhaps since we got the car. The state of the exposed end of the bolt would support that, it looked 'old'.

Friday, May 6, 2011

The Sony Discman (car-ready) CD player shrieks and burbles weirdly, and today I finally noticed that the noise is coming by way of the power plug! When I powered the Discman with batteries, yet left the power plug in the radio (which is what causes the audio input cutover) it still made noise. The other power cable (for a different portable CD player) doesn't do this. Very weird. I'll make a new power cable for the Sony, that should cure it.

Saturday, May 7, 2011

The LF tire is wearing excessively on the outside. I rotated the tires on that side to mitigate the problem, at least until/unless it gets addressed properly.

Friday, May 20, 2011

Long past time to put this car away for the season, but no chance to work on it 'til today. I wire-brushed the rusty spot under the bumper, it's where the RF fender joins the front piece of metal. It holed, but it's not really in a visible place so I contented myself with cleaning it off, priming it, and shooting some random rattle-can silver paint at it. The color blends in far better than I'd thought it might.

...After work I cleaned out the car and ran it down to storage for the season. I disconnected the battery this time.

Sunday, November 6, 2011

Time to dust off the car for its winter tour of duty. I charged the battery and started it, first having to do a little work on the positive battery clamp to get it to connect tightly, and it started easily. Then it died after idling a little while and refused to start after that. I primed the fuel system and charged the battery, but no go. It tried, but wouldn't fully catch. I finally grabbed one of the batteries from the genset and some jumper cables, which did the trick. A huge black cloud poured out of the exhaust, the engine had gotten loaded up with fuel. I ran it at high RPM for awhile to stabilize, and after that no problem. I drove it up top and put in power steering fluid and aired all five tires, then put it back on charge to replenish it after its episode. The battery is thirsty. Will need to clean it out, washing glass and etc., but for now it looks nearly ready.

Thursday, November 10, 2011

Another dust-up about the audio system in this car, so to solve (?) the problem we stopped by Car Toys and bought a new Alpine CDE-100 CD player. On sale, $99 with installation, not that I'd let the clock-racing butchers near one of my cars, not even a Chicken Wagon! (Without installation: also $99. Sigh.) It will do MP3 (also WMA/AAC) CD's, and has both an auxiliary jack and a USB port on the front, and doesn't have a freakin' light show to distract you from the road. The lighting also seems somewhat subdued, which is important to me, although the main buttons are blue, which I hate. (Alpine used to use a nice gentle green, which I really liked. Everybody seems to want blue now but I hate it, because due to the biomechanics of the eye it is generally fuzzy and out of focus, especially since they're usually using ultra-bright monochromatic light... just because they can I suppose.) We'll reserve judgement until I can see it at night, lower-end units like this do not dim when the dash lights are on.

Friday, November 11, 2011

I stopped by the junkyard to try to get some special Becker sockets to make a cut-free adapter cable for the Alpine, but I was skunked. They only had a 116 in, and apparently it uses different connectors. I thought I already had some in the junkbox, but I haven't been able to locate them.

Saturday, November 12, 2011

Acting on a hunch I went down to the parts cars. Smelly (300D, 123), as it turns out, had the same connectors as the junkyard 116. The '87 300TD, on the other hand, had just what I wanted! I grabbed the two Becker sockets for the dashboard speakers and took 'em to the bench, and soldered them, two spade lugs, a ring, and a bullet connector to the CDE-100's harness. Everything will hook right up to what was there for the Becker, except that new radios have embedded clocks and electronic station memories and thus require continuous +12 V, which isn't provided for the old Becker. Fortunately I found that there was an unused factory 2-pin connector taped to the cable that feeds the cigarette lighter and radio, and it had battery power on it. Score! (That's what the bullet connector was for, I ransacked the junkbox and found one that was a little larger than the norm and which fit snugly into the bore of the connector.) With this done the Alpine installation is completely reversible, and/or can be transferred quickly and painlessly to another similar car.

I tried it out and the clock was easy to figure out how to set, even without the manual. The antenna goes up and down, and (nice!) goes down when it's on CD or Aux. The radio works and I set a couple of stations. I tried out a home-recorded CD and it worked just fine. The clock and station memory held with the key off. Yay, Alpine.

Hopefully this will eliminate the nasty noise that was coming from the general vicinity of the other seat. RIP, iPod-ified Becker, I wish I had never wasted my time on you.

Monday, November 14, 2011

I cleaned the insides of the windows with my usual 1/2 ammonia, 1/2 alcohol mixture, in a spray bottle, and paper towels. Smelly, but effective.

It shifted oddly a couple of times yesterday, so I added 1/2 quart of ATF. (The dipstick [cold] showed low again.) I was out of time to do more, but I did notice that the oil was low and it was long past time to change the oil again. Jill really can rack up the miles when you're not looking...

I bought an oil filter at NAPA. $12.

Tuesday, November 15, 2011

After work I changed the oil and filter. Another 11kmi, not good! The oil was sludgy enough that it didn't want to suck out the top. Eventually it did and I got things put back together. When I started it there was the usual delay until the oil pressure came up. When I got out to check for leaks... OH, YEAH!!!!

I botched the filter install somehow, the cap isn't sealing. (The NAPA cheapie's O-ring was loose-fitting, and wouldn't really stay in place while installing the cap. I hate working in the cold and dark, it's hard to work and hard to see, even with a bright work lamp.) Black oil everywhere. In disgust I shut it down and went inside for dinner and to warm up.

Wednesday, November 16, 2011

20 °F this morning, not too fun to be working on the car! I got the filter sealed right, but it was wedged down due to the pinched O-ring, and during my attempts to get it loose I broke the pressure line to the ALDA. Duct tape, for a temporary fix, I was out of time.

...When I got home I shoveled dirt over the big black puddle on the concrete. It started snowing while I did this.

Thursday, November 17, 2011

The brake pad light has been coming on, so this morning I jacked up the car and had a look. Bendix calipers on both sides, but the LF side didn't have any pad sensors. The RF side did, and both where being sliced into. I got out my junkbox brake pads and found two that were better, and put those in instead. The car could use a full brake job, methinks.

...The car drove well and the brake light business was gone. At noon I swapped cars with Jill, this'll be hers for the winter.

Thursday, December 8, 2011

I got home from work and it was about 25 °F outside and I knew Jill was going to rehearsal within minutes, and yet I found the car not plugged in! I'd told her, repeatedly, that it needed 30 minutes to an hour of preheat in this kind of weather in order to start reliably, and yet...somehow it would be my fault. Yeah. So I plugged it in.

Sure enough, within 5 minutes she was ready to go but the car wasn't. We fought it awhile and really gave the battery a workout, I even went so far as to point a space heater down its throat but no good. It half-caught at times and really filled the air with a stinking cloud of vaporized diesel, but there was no running that night. I noticed that the glow plug light was no longer coming on, which was not a good sign. We finally gave up and she drove off, late, in a huff in the Frankenheap (not her favorite car, though it was all warmed up and has the happy Christmas lights); I put the battery on charge.

Friday, December 9, 2011

This morning I went out in the 25 °F cold, rigged some lights, and tested the glow plugs. Two of the five, #'s 3–4, were open circuits. Yeah, no way that'd start in this weather! (We may finally be seeing some fallout from the car's poor-man's violet-wire afterglow system.) I went to the parts pile to see what, if anything, I had on-hand in that line, and found five pencil-type that weren't obviously labeled for the OM60x engines. Two Bosch 0 250 201 039, two Autolite 1103, and one Beru 0 100 221 138. The Bosch, at least, cross-reference to this car. I was able to replace #3 easily enough with a used Bosch plug, but I ran out of time on #4, it's hard to get a 12mm wrench on it securely enough to not round it off. I did get the wire off of it, at least.

...After work I came home a bit early to get enough time to finish the job before Jill had to go to orchestra. I was able to get an open-end wrench on the bad plug and break it loose. It was a pain walking it out half a flat at a time, but I eventually prevailed. The new (used Bosch) plug went in easily and I got it all connected back up. (The block heater'd been on all day, the engine was pleasantly warm to work on though it was still about 25 °F outside.) I tested the plugs with the ohmmeter and all were good, then I used the Fluke current clamp and a bit of 10-gauge wire to feed power to them serially through the connector plug from the big fuse screw. All drew 20–25 A at first, dropping down to about 14 A over a period of some seconds. I then buttoned up the car and started it. No problems and less than half a second of cranking was required. It didn't really want to shut off, however, and I didn't see any problems in the vacuum connections from working on it. It's just really cold, and whatever leak it has is most unhappy in the cold. That will need addressing soon, methinks.

The car started for her just fine and off she drove... When she got back (late) she reported that all was well.

Wednesday, December 14, 2011

Jill says the car intermittently doesn't start, just cranks, so I checked the glow plugs again this morning. All test fine with the ohmmeter, and the fuse looks good. Strange. I used the repaired trouble light to see what I was doing out in the cold and dark. (On the end of an extension cord, its troublesome reel cord doesn't reach to where the car is normally parked.) Worked great.

I also got out a piece of rubber vacuum coupler and patched the pressure line to the ALDA that I broke before. The duct tape had come loose, imagine that!

Saturday, December 17, 2011

Many moons too late, but I finally was able to park this car inside (since I moved the SEL out of the way) as an anniversary present of sorts for Jill.

Friday, December 23, 2011

Jill's been having persistent starting troubles, but all the GP's are (now) good. It cranks just fine, but won't start. Intermittently, according to her. To me it sounds like the GP's just aren't doing their job well. Today I had a chance to dig into it a little bit. I started by cleaning the relay connections and putting Caig Deoxit on them. I pulled the big fuse and it was good, but I still cleaned it off with a little wire brush and put it back together with Deoxit. I pulled the relay and took it to the bench, but it seemed to behave well there. (Interestingly, if the big fuse is not there the relay will buzz loudly after it times out, I wonder if that is deliberate? I'll look into that further later, it may be one of the system's self-diagnostic traits.) Back on the car I checked the GP current, it started out at a peak of 130 A and dropped down to about 50 A steady-state. The GP's, however, were only getting at most 10 V on them, they're rated at 11 V. I measured 0.2 V drop on ground side of battery to the engine block, which was good. Between the battery positive post to the relay power post I measured a 2 V drop while the GP's were on, that's terrible! She had to go so I didn't get to dig into it further, but I imagine that either the feed end of the power wire to the relay is corroded or loose, or else the wire itself has been damaged somehow. I checked the ETM and found that C105 is where this wire supposedly originates, and that this is the three-terminal power block right next to the battery. I'd already loosened and tightened its three screws, and sprayed Deoxit on them, as part of what I'd first done, but nothing more. Next time.

The car started beautifully, of course, but I'd had the block heater on while I was working on it, and of course the glow plugs had gotten run a fair bit while sleuthing. (The battery charger was on it all the time, to replenish the losses.) And it was parked inside. I expected no trouble this time.

Sunday, January 8, 2012

Jill's still having starting troubles so I went and did a bit more testing. There's still a 2 V drop on the positive lead during glow. I opened up the terminal block near the battery and it seems to be all OK, it's looking like the wire itself is degraded. I may need to route another one. That's a bit scary, since it's unfused, gotta do a real good job so that there's no chance whatsoever of pinching or abrasion over time shorting it out.

I also think that the glow timer light is being overly optimistic, I suggested to Jill that she use the seat belt light instead as it runs longer.

I queried the mailing list, and three other 123-model cars had drops of 1.0 V, 1.3 V, and 1.7 V. Sounds like there's a bit of a spread there, but I wouldn't be proud of any of those figures. Perhaps MB skimped a bit on the wiring here?

Wednesday, January 11, 2012

The coolant level was low, very low. I'd noticed a leak weeks earlier and had tightened the drain cock, which seems to have cured the problem, but I didn't notice at the time that the coolant was particularly low (it probably was), it's hard to read the level in the reservoir in poor light. I ended up putting in about 3/4 gallon of G-05 mix, which is a lot. I also filled up the washer reservoir, the nasty crap they spray on the freeways around here is really tenacious goo.

Jill said that yesterday the radio acted weird and cut off when the glove box was opened. I checked this morning, and it was indeed repeatable. Weird. I pulled the radio out and checked the wiring, and the +12 V switched feed dropped to about +6 V when the glove box was opened; the light itself didn't come on. The glove box light, radio, and cigarette lighter all draw from the same fuse. It turned out that that fuse was intermittent, though looked fine, so I reversed it in its socket and used Deoxit on it, and its neighbors; that cured the problem. It probably happened because she's using a new, cheap seat heater pad I gave her for Christmas and the fuses are old and have divots in the contact ends from vibration and age. I put the radio back, we'll see if it holds up.

While I had it out I used the Deoxit on the dome light switch, and refreshed the paint on the white stripe on its knob. I've wanted to do that for awhile.

Jill also had said that the windshield washer nozzles were clogged. I pulled the hoses off of them, poked them out with a dental pick, and blew backwards through them with compressed air. I also flushed the lines to remove any dirt that might have been in there. Unfortunately one of the 90° fittings broke when I pulled it apart so I cleaned it off with brake cleaner and tacked it back together with cyanoacrylate glue. (I should have warmed it with the heat gun before pulling on it.) I then mixed up some 5-minute epoxy and potted the break, and held it over a warm light bulb and rolled it around until the glue started to set (both to keep the glue coating even and to keep it from dripping), then I clipped it in place over the lamp to finish curing while I got ready for work. When ready I put it back together and re-aimed the nozzles with the pick. (Yes, I need a new fitting but I didn't have a new fitting on me, doing this got it back on the road today.)

I thought it was cold, at 16 °F yesterday, but today it's 13 °F! Good thing I'm able to work in the (one) heated garage again since I moved out the SEL.

Jill's new iPhone charger plug doesn't fit in the cigarette lighter socket, nor did the USB port on the radio seem able to charge it. I took a look, and she'd bought a 'mini' charger, which didn't have a round plug but rather an oval, and it didn't fit securely into an actual cigarette lighter at all. (I'm sure it's fine in a power-only socket.) I checked, and the radio was unable to charge the iPhone, it either doesn't have enough current available or it needs some kind of configuration on the USB plug that it's not seeing. The radio did power a USB memory stick, so it's not defective. I had a wall-wart power-only socket in the junk box, so I sacrificed it (sob!) and a spare cigarette power plug and spliced them together to make a short extension cord. (I used heat-shrink tubing to re-insulate it and make it neat.) With this in place the iPhone would charge without problem.

I then removed the Bosch 0 333 402 507 (MB 002 545 06 32) 12 V/5-Cyl glow plug relay from the car and opened it up. Besides the big relay it had the usual counter-wound 4:1 plug windings around a reed switch (tres elegant!) and some circuitry: five transistors, two thermistors, nine diodes, a bunch of resistors, two precision capacitors, an LM2903 op-amp, and two electrolytic capacitors (one 220 µF, one 100 µF) on a coated PCB. I pulled the electrolytics and tested them, but they seemed OK. I replaced them anyway, but I doubt it'll make any difference. I used hot glue to attach the new capacitors to the board for vibration resistance, the originals had also been glued in place. I filed the one pitted contact (of twins) on the relay on general principles, and put it back together as I was out of time. In the ~50 °F garage the GP light was on for about 5 seconds, and the plugs timed out after about 24 seconds. (The relay was probably still at room temperature inside where the thermistors are.)

The manual has relevant jobs:

The first one is actually the most interesting. The manual implies that at freezing the required preglow is about 7 seconds, which seems short to me. For now I've told Jill to wait at least until the seat belt light has extinguished, or for a slow count of 20.

Here is an approximation of the glow time/temperature chart from 15-705, for quick reference:

Disaster! This morning was very icy on the hill, and as I'd had a fair bit of trouble descending I resolved to call Jill from work and suggest that she not go anywhere until it'd warmed up, or cooled off, or whatever. Too late! By the time I got to work she was calling me, telling me that she'd spun out on the hill and slid off the road, knocking over the stop sign at the bottom of the hill and bashing in the driver's door.

Crap.

I drove back home to look at it, and it appears that if she had managed to miss the sign there would have been no damage at all. As it is, the door is pretty much destroyed. It completely took out the handle, so she has to get in on the passenger side. As befits a Mercedes, once inside she can get out normally, and slam the door shut. There's a small crease in the rocker under the door, but it's minor and can be disregarded, I see no other body damage. The key cylinder of the wrecked handle looks intact, so I should be able to swap it into a junkyard handle to keep the key the same.

Looks like I'm going to have to come up with a new door. I have Smelly in the woods, but it has no handles nor any other hardware. There's a 123 at the U-Pull, I'll swing by and see what it's got. The car's going to look bad (worse?) after repair, it's unlikely that the replacement will be the right color.

Jill also apparently needs ice driving lessons, she was holding the car in low gear to keep the speed down (good), but did not put the car in neutral once it broke loose (bad). (She should have hit neutral and recovered via steering, before pumping the brakes to slow down as best she could.)

Tuesday, January 24, 2012

I went to the U-Pull, and found the 123 was still there and had a decent door. It was a 1980 Euro 280E, so it had a cloth interior and crank windows, though it did have power locks. The bottom trim piece had come off, but was still with the car, the mirror glass was gone, and the door check was shot. There is some rust setting up in the bottom, at the seal channel, so there'll be some work to do there. Anyway, I removed the door, it came off pretty easy, just the four bolts and the door check strap pin. I cut the vacuum lines where they came through the hinge. About $25, though I did find $1.06 in change in the car to offset the expenses. (This included a $1 coin, which looks a lot like a souvenir rather than money once the shine is off it! They seem to be corrosion-prone.)

The same car also had a pair of Bosch Euro headlamps. The glass was broken out of one and the reflectors were pretty degraded, and both had broken-off mounting ears, but I grabbed them, and their vacuum hoses, anyway.

There was a 1960 180 there, which is a homely little cuss, a 201, a 124 300D and a 140 S320. (All airbags were deployed.) Odd that there was nothing from the 70's. The S320 looked interesting, this is the first time I'd seen the double-pane window glass up close.

Wednesday, January 25, 2012

I went back to the U-Pull, and tackled the 1987 300D (W124), and liberated its glow plug relay and the high-current wire from the battery to the relay. That was a pain and a half. I'd like to try bolstering the existing GP wiring with it, we'll see.

Saturday, January 28, 2012

I started taking apart the replacement door, and the farther along I went the less happy I got. It was in worse shape than I'd thought, the whole bottom channel for the weatherstripping was rusted away, and there was a lot of rust in the door bottom too. Looks like it started under the weatherstrip itself, and worked its way in from there. (Rather than plugged drain holes causing rust to start on the inside and work out.) The window tracks were messed up, which made it bind on the way up, which caused PO to use too much torque on the handle which flexed the door's inner metal panel and cracked it over time. So I'm looking at a serious amount of rust repair and some welding, all for a door that's the wrong color anyway. Ick.

OTOH I could just wait for a better door to come along, if I could get the bent door working better. (I'd planned on this possibility all along, the door itself was cheap enough that if all I got out of it was a handle and the piece of belt trim I'd still be happy.) Figuring I had very little to lose I opened up the damaged door and removed the remains of the ruined door handle, and started hammering the metal back out. I used a chunk of maple firewood that tapered down to about ½"×1½" or so, yet had a mallet-sized big end which I could hit. The thin tapered end reached through the holes in the door's inner panel, allowing me to direct the force better than a big chunk would. Being wood it's softer than metal and less likely to poke dimples into the panel. I had my son hold the door while I whacked away. I also used a big crowbar to pry and pound at the crease lines in the metalwork (the ones that belong there). I used various small crowbars of my acquaintance to hook through the door handle holes and pull out, trying to restore the correct profile in the area without doing too much further damage. That actually went fairly well. I removed the bottom trim strip and found that most of the damage at the bottom was to the strip itself, which is metal with plastic molded around it. (The strip comes off with one 8mm nut at the trailing edge, behind a snap-in plastic cap, and a hook at the front. I had to break it loose from the plastic retaining clips along the middle and then pull backwards to release the front hook.) I think I'll be able to restore the strip to usability on the anvil. (The replacement door's strip was pried off, breaking off both the hook and the retaining screw.) At this point the door opened and closed well again, you could use a finger to grab the latch release eye and pull the door open. The inner lock mechanism worked fine. It no longer scraped at the front as it opened. Pretty good for a first cut at the problem, I thought.

With this it was time to address the door handle itself. The replacement, naturally, had no key and its weather door was long-gone. But it was all there. The original was shattered into pieces, but its key cylinder was untouched. (The actuating rod was bent, however.) I found a bent siding trim nail in the metal recycling bin that looked to be about the same diameter as the roll pin that holds the actuating rod mechanism to the lock cylinder. I straightened that and had my son hold the handle against a makeshift anvil while I drove the roll pin out. (I had to straighten the nail a few times along the way.) Once the pin was out the lock cylinder pulled straight out of the handle. (Make sure the key is in the cylinder while you do this, and don't lose the lock's torsion spring as it comes loose! If you remove the key you could lose all the spring-loaded lock wafers, or at least mix them all up and no longer be able to operate the lock.) I then cleaned the lock guts with brake cleaner, removing the dirt and grime. I then re-lubricated the lock wafers with spray graphite lock lube. We then took apart the replacement handle the same way. Its lock was full of dirt and grunge, the missing weather door had obviously been necessary.

I tried to straighten the bent operating rod, but it was pot metal and broke, no surprise. The replacement had a differently-shaped end where it engaged the latch, but seemed to work OK nonetheless. I put the good handle back together with the original lock cylinder and the replacement's operating rod, we reversed the anvil/roll pin operation. Once it was together the key operated as it should, and I slipped the handle into position. It worked! I then tightened the three screws.

At this point the door was fully operational, but still could use some more cosmetic shaping of the metal, and the trim pieces repaired and replaced.

Sunday, January 29, 2012

I got out my as-yet-unused Harbor Freight body kit (hammers and dollies) and tried to do some more straightening. I think there was at most moderate success, but it was worth trying. The main problem is access. I did remove the handle and straighten things out around there a bit.

I was going to touch up the paint, I'd found an old blue rattle can. I was going to spray in the cap and dab it on to the bare spots, but the can seemed flat. I stupidly decided the propellant was gone and punched a hole in the side to stick a brush into, and the can promptly liberated most of its contents onto us, and the car—the bulk of it on the door. Oops! We spent a fun time with turpentine removing it from the glass, the trim, and ourselves. I left it on the paint, it did mostly cover the door after all. I was able to find a little left in the can to use the brush on, for the inside and the weatherseal channel. I had to use a green can to do the scrapes on the inside of the door where I had worked on it. That can, too, had trouble—once it started spraying it wouldn't stop.

Both cans ended up in the garbage. I then straightened the bottom trim piece out with a couple of hammers. At least it was more or less straight, though the attachment channel was wrecked in one spot. I figured out how it went back on on the car, you slide the hook into the front hole, hook it over the tops of the plastic buttons and snap it down over them while working the bolt into the rear hole. It didn't mate perfectly, due to the remaining damage and the inability to clip over the button in the bent area of the channel, but it's not bad. Between the two doors' trim strips I found enough red snap-in trim buttons to get the replacement belt trim back in place. That masked the damage a lot, it being there and reasonable looking. (While I was in the area I re-attached the fender belt trim too, it had started coming loose. I tried pushing its depressed area out a bit from the wheel well, I'm hoping that'll help.)

I started to put the door back together, but the window didn't work. Stuck at the top of the track. Seems like the track might have gotten a tiny pinch in it, because once you can get the window down an inch or so it works fine. We were tired and hungry, though, so we stopped for the day.

Monday, January 30, 2012

I worked on the window, and I didn't have much luck. The window also binds against the side-impact bar, and doesn't want to fit into the weatherseal at the top. Things are all out of whack, but I needed to get it back together so Jill could drive it. The window is marginally more movable now, at least, and should hold for awhile. I really need to find a good replacement door. I then put the door back together, that was uneventful, and cleaned up the area. I suppose the car does look better than it did, and it certainly works better, but it doesn't look all that good to me.

Sunday, February 5, 2012

The driver's door had a bit of a wind leak and the upper corner of the window frame didn't look like it was fully flush, so I opened the door and rolled down the window and whanged away on the window frame with a rubber mallet. This bent the frame inwards some, which cured the problem. (This is quite nerve-wracking to see done, but it's the approved way!) Slapping down a stop sign no doubt shifted things a bit.

Tuesday, February 7, 2012

The muffler fell off on a speed bump today. It'd been cracked at the pipe, probably from when it went into the ditch, and finally let loose today. I put it into the trunk. At least the turbocharger is itself a nearly-adequate muffler and there's a center resonator, the car doesn't sound too bad this way.

Wednesday, February 8, 2012

I checked the fluids, and it needed power steering fluid, a pint (at least) of ATF, and a quart (at least) of engine oil. Thirsty girl! I looked at the muffler and it looked like it broke off at the joint where I'd (gas) welded it on in the first place. That weld was very poor, and didn't penetrate properly. I thought it'd go back on just fine after cleaning it up, and this time I'll use the wire-feed.

Saturday, February 11, 2012

Welding day! I backed the car outside and up onto ramps, wire-brushed and ground the muffler end clean(er), and dropped the pipe from the car. I started brushing the pipe clean and found that there were some erosion holes along the top outside bend near the broken joint, so I had to clean that up more, find a scrap piece of muffler pipe, cut a patch for this area, and weld it on. (The rest of the pipe looked great.) That took a fair bit of time, so once I had it welded on I broke for breakfast.

I hung the muffler and pipe back in place, first using the handheld bandsaw to align the joint better, and tack welded the joint along the bottom, then I dropped it all back down from the car to weld over the top, then hung it back up permanently and finished the job. I used my $50 Hobart gasless wire-feed welder, it's portable. The job was not made more pleasant by the light drizzle that was falling the whole time.

Jill drove off later, and said that it was back to normal.

Friday, February 17, 2012

Jill reported that the right low headlight was out. Turned out to be a corroded fuse. She also said that the right washer nozzle wasn't working, and I found that was because the fitting had cracked and popped off. I put a collar of heat-shrink tubing around it and used the butane torch to shrink it, which holds it in place. Onwards to Enumclaw! (Skiing trip.)

...Turns out the monovalve insert appears to be malfunctioning, we had plenty of heat until we got well on the freeway. (At speed, once it starts modulating the heater core temperature, the heat began fading. If you stopped the heat came back. Classic.) It would wait until we're on a road trip to exhibit these problems!

Tuesday, February 21, 2012

I removed the monovalve insert before our return trip, and it is indeed torn. There are considerable signs of water leakage inside the monovalve housing. I shook out the water in the plunger and put it back together, hoping that removing the waterlogging would help get us home.

...It did, sort of. But it is definitely in need of replacement! We left the heat on MAX, on low fan, and modulated the cabin temperature via a window. (If you let the monovalve cycle it tended to get stuck 'off'.)

Friday, March 16, 2012

Coupla little things, Jill stopped by work today and I cycled the window switches until the LR window would go back up. I also re-set the spring in the glovebox latch so that it would close again. Just some of those little chores.

In the evening I changed the oil. (Finally! Another 7kmi change, nothing to be too proud of.)

Saturday, March 17, 2012

On our skiing trip (local, up Mt. Spokane) the RR door check finally decided to lock up. I tried to finesse it closed, but it wasn't having any. I finally just forced the door shut, destroying the door check and rendering the door unusable. Crap.

Thursday, March 29, 2012

The Chicken Wagon is sick. Jill said it had not been wanting to go forwards yesterday, and she'd already put in a half quart of ATF, so I checked the level again and was very low. I put in another half quart and it would move, so I brought another quart with me. I was able to check the level once I got to work and it seemed quite low, so I put in another quart. Even with plenty of fluid it doesn't want to go into first gear, though reverse is just fine. It also stutters sometimes going into other gears. Methinks it's perhaps on its last legs, this is fairly sudden. It won't downshift into third, and sometimes it goes neutral-y on steep downhills. There's obviously a leak somewhere, but is it possible that whatever is leaking is causing this problem? Or did Jill try to drive it too much with not enough fluid (due to the leak) and ruin the clutches? It didn't behave well on my way home from work, and I checked the fluid level formally when I got home. A tetch high, even, so it's not slipping due to a lack. We're down to our last working cars, something has got to change.

I did a quick survey, and it is possible that this could be the infamous B2 piston failure, though the symptoms don't line up 100%. (Worse would be a B2 band failure.) The inability to get moving at first, especially on a hill, but normal freeway driving does match up though.

Wednesday, February 6, 2013

I put the battery on charge, it was pretty thirsty.

Saturday, April 20, 2013

I put the battery on charge, again.

Friday, May 5, 2017

The battery turned up dead this year. Jill states that she wants this car running as a backup, so today I bought another one. $119 at Home Depot, of all places.

Wednesday, August 15, 2018

We've decided to just take the car in to get the B2 piston (transmission) fixed, I clearly don't have time to do the job. Fernando has retired, but Silver Star Automotive knows the car model and the job. This morning I put the new battery in the car, after killing all the wasps living in it, and it started right up. It goes into reverse, but not forward, so that's a fairly definite sign of the B2 problem.

Wednesday, August 22, 2018

Daniel and I took the car to the shop. We got it started early this morning, when traffic is next to nonexistent, and towed it out to the road. We unhooked, and I started coasting down the hill. Once I was up to speed the transmission would engage, confirming that it was a B2 piston problem. I drove it all the way to the shop, running every stop sign and timing the lights so that I didn't have to stop. Not 100% legal, but I was being very careful, following Rule #1, and we were always ready to revert to using the tow rope if a stop was necessary. It helped that most of the trip was freeway, under very light early morning traffic conditions; Daniel followed me in. I rolled to a stop across the street from the shop, after which it would not move again, and went inside to take care of business. That done, I dropped Daniel off at school and went about my day. Fairly smooth operation, I thought.

Wednesday, August 29, 2018

Picked up the car, $818.92, and it was indeed the B2 piston. The car drove home normally, whereupon it got parked again. I disconnected the battery.

Tuesday, September 5, 2023

There's been an interest in this car, which I think I could let go of for the right price. Ten years in storage is long enough.

I connected the battery, which I'd charged sporadically over the years, and the car started right up, even though the battery was weak and could barely turn the engine over. I brought it up into the yard and washed it, leaving it to idle during. Once clean (enough) I moved it over to the parking pad and put it on charge while I vacuumed and got it ready for (potential) sale.

Oddly, the gas cap is missing. It must have been stolen, perhaps when it was on the street at the shop.

Friday, September 8, 2023

I stopped by the U-Pull, and picked up a gas cap from a W126 380SE. We'll call it $5.68, counting the $2 entry fee.

Saturday, September 9, 2023

Showed the car to a potential buyer. He wasn't scared off by my $3,200 ask, at least. (These particular cars have appreciated a lot in the last couple of years.)

Sunday, October 29, 2023

Put it in storage, and put a Battery MINDer on it. The car needs brake service, and it had real battery trouble getting started.
