Re: [MBZ] It's always something...
The fallout from the dead 560SL battery in Missoula has so far been a cleaning and gluing together of the battery box and lid, which were well shattered by ham-handed past battery work. But yesterday I finally got to pull the alternator, and one brush was notably short, and arcing had chewed its slip ring a bit. When spinning the alternator by hand it sounds 'dry', I'd say that it really could use a new bearing or two. Checking my records I find I've done this before, three years ago on the 190D, and the place to take the alternator is _Spokane Auto Electric & Repair_. They carry everything, and can turn slip rings too. I just need to take it apart and re-assemble it. Not an issue. Step one: use a Sharpie to mark the phasing of the two housings. As before, I then put two screwdrivers into the fan and set them against bolts through the alternator mounting holes. A 22mm box-end wrench went over the nut, and then a hammer striking the wrench removed the nut easily. (Inertia, not so much force on the fan, was the counterforce.) The pulley, fan, and all the spacers just drop off the front then. I strung them on a piece of wire to keep them in order. A hammer and a screwdriver removed the shaft key. Removal of the fan exposed the four screws that held the body together, those came out easily enough. (Don't slip and bugger the screw slots, or you'll really have a problem!) A brass hammer tapped around the rear housing caused it to drop away from the front housing and rotor, the rear bearing stayed with the rotor. The rear bearing was _very_ dry, it's close to failure. Most of the grease appears to have worked out of both bearings. I removed the four little screws that released the front bearing clamping plate, and with the nut on the shaft the brass hammer drove the front bearing out of the front housing. Checking the tool box I found a recently-acquired New Britain puller (50 cents at a garage sale) that is a _perfect_ fit to the rear bearing. It clipped over it and with a twist and a little pop it came right off the shaft, the flat end of the puller's bolt slipped perfectly through the bearing. (It was _sweet_, I love using good tools!) The front bearing is the hard one, but I have found that I can use a clamp-together flat plate bearing puller in conjunction with a 2-jaw puller to pull them off their shafts. I kept the front nut half-on the shaft in order to constrain the point of the 2-jaw puller. It took quite a bit of force, but the bearing pulled off pretty easily, and the procedure didn't seem to deform the bearing clamping plate too much.

Re: [MBZ] It's always something...
I slipped the old front bearing back on part way, wrapped a strip of pop can metal around the back shaft, and chucked the rotor into the drill press as a vertical lathe, with the front bearing resting on the table and the shaft protruding through its central hole. I then got out a flat stick and some emery paper and had at it. That worked, but it exposed the fact that the one worn slip ring had a noticeable divot in it, presumably from arcing. I got more aggressive with a file and flattened it, mostly, then re-applied the paper and stick. (Taking the hairline groove completely out would have removed more material than I was comfortable with doing.) I now have a nice shiny smooth, and mostly flat, pair of slip rings. We'll see later if I made a mistake or not! I didn't have time to do much more. The original front bearing is marked FAG 6303.R.10.18, and also A.Q and ITALY; one dust cover is marked 6303 S 457, the other 6303 S 478. The replacement is also FAG, labeled on the box 6303.2RSR.C3 but marked on itself 6303.C3 and E275-0331 HB; one dust cover has 6303RSR and W263 on it, the other has 6303RSR and W243 on it. The original rear bearing is marked SKF 6201-2RS1/C3HT228VU035 (a bit sketchily, as it's on the outside of the race and has some scuffing that somewhat obscures the legend), and also B (or 8) and ITALY, the dust covers appear to be unmarked. The replacement is Koyo, labeled on the box 62012RDC3 but marked on itself only C3; the dust covers have 6201RD, KOYO, and JAPAN on them, once side also has 555 and the other has 519. -- Jim ___ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com

I forgot to mention that I picked up the new bearings yesterday at the local bearing supply house, $15 for the pair.

Re: [MBZ] It's always something...
Reassembly time! I cleaned the shafts of the rotor and put it in the freezer, and put the bearings and housings in the shop oven at 200 degrees F. They just slid together after that, with only a little tapping with a hammer and some deep sockets to seat the bearings fully in place on the rotor. You definitely want to make sure to remember to put the captive retention plate on the front shaft _before_ you put on the bearing! The body reassembled easily then, the worst part was getting the little half-round key into the shaft's notch. It is interesting that the belt pulley is two separate sheaves, I didn't notice that before. The alternator spins smoothly and quietly now, it's nice. I then put it back in the car, nothing special about that procedure. I checked the fit of the battery in the box, and I found that with the red plastic spacer board in place the lid didn't even come close to fitting down over the sealing lip of the box, which explains how it had gotten so broken up: they'd tried to buckle down the lid but it wouldn't go, and they tried forcing it. I imagine that what had happened is that at some point someone had put in an incorrect battery, a small cheap one rather than the correct (and rather large) Group 49, and that the cables didn't reach the posts so they'd put a board in to lift the battery up a bit to reach the cables. Later, when the correct battery was installed, the board was not removed. With that all figured out I then wiped the battery compartment clean with a damp rag and reinstalled the newly-repaired battery box, then the battery. As I've found before, the hardest part was getting the positive grommet back in the box. I touched up the paint on the buckles, etc., and reinstalled the hatch cover and the buckles. To maintain the clocks, etc. the car's been on the battery charger this whole time, but set at 6 V to keep the voltage peaks down since the battery wasn't there to serve as a filter. Seems to have worked, anyhow. I was going to put the used front bearing into the junk alternator that's been underfoot for quite some time, only to find that it's not the front bearing that's loose. The bearing socket in the front housing is what is loose, the bearing probably got tight and spun in the housing at some time and chewed it out. It's possible that some shimming would restore it, but it's not like I really need it at this point. I then fired up the car and checked the running voltage, it was 14.3 V which is right in the pocket. Done! I tested the keyless entry fob and it was working fine, once I tried it a few times. (The keyless system sits loose in the battery compartment.) -- Jim ___ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
Re: [MBZ] It's always something...
Jill called me at lunch from the library parking lot, and said that the 560SL battery (that went through Hell with the alternator incident) made a big 'pop' noise when she went to start the car, and fluid started dripping out of the back. (It also wouldn't start, and had been getting difficult to start recently, and could sometimes barely turn over though the voltage and charge state always seemed OK.) Sheesh! I got there and opened it up, and the newly-repaired battery box had contained all the acid from the 8-year-old NAPA battery's case blowing open! It had cracks and fractures all over the place, and had leaked thoroughly. We got a pan of water and sluiced it off before lifting it out onto the ground, and diluted the acid stream that was running away from the car. I put the battery on one of the rubber winter floor mats in the trunk of my car, and we went off to Les Schwab where we bought another Group 49 battery for $108. (I washed off the floor mat with their hose.) It installed easily enough into the car, but the cables didn't reach well and I didn't have time to fuss with it. (It's possible that the new battery is a bit shorter than the old one.) It got her home, anyway, but the car wouldn't start again because the positive cable had popped off sometime along the way.

Re: [MBZ] It's always something...
I had a battery on a piece of equipment blow up in my face many moons ago. We had jumped the battery, and when we disconnected the jumpers, the spark ignited the hydrogen gas from the battery, which was now charging. Ever since then, I am very careful to hook up the last connection as a ground far away from the dead battery, and it is the first one to be disconnected.

Break in an internal bus bar in the battery? Hit the starter and turn the battery into an arc welder. Had to be that, it's consistent with the earlier behavior. The battery had suddenly been acting 'weak', it could barely turn over the car, yet the voltage was just fine and it took a charge 'normally'. But if one of the cells was running at half capacity, or less, and then made contact across the break with a fully-charged set of plates in the cell, in an atmosphere of H2/O2 freed by excessive discharge (or charge) caused by the normal currents being forced into a small area by the break and the other five (strong) cells... -- Jim ___ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com

Re: [MBZ] It's always something...
When I did generator work we used to see battery explosions with some regularity. Here's why: When the electrolyte gets low in the battery (from being constantly charged, as stationary duty batteries are) the tops of the plates get exposed. When a large load is applied to the battery, as in when the engine cranks, there can be a spark or arc across the exposed plates. Since there is most likely some hydrogen present in the cells, this ignites, causing a pretty spectacular explosion that usually rips the top of the battery off. A good reason to be checking the electrolyte levels on a regular basis. I haven't found this to be as much of an issue in automotive applications, probably because the batteries in such an application aren't on a charger 100% of the time like a stationary engine battery is.

Re: [MBZ] It's always something
My neighbor gave me a fairly nice 10 year old john Deere made Scott mower that is a fairly heavy duty model with 54" deck, took care of my need to buy a new mower. It was using about a quart of oil an hour. It has a Kohler command engine and quick search turns up it had bad head gasket or 2. I ordered the head gasket set a while back and tore it down today. The right side was leaking/burning for sure. Left side was not. Everything was going nice and smooth until I was using torque wrench on last head nut on the 2nd head and snap, damn head stud snapped. I don't know if I had the torque wrench set wrong, or what. I did pull the head back off and there is these metal collars on the base of the studs in that side of the head that sort of hold the gasket in a certain position. They were somewhat bent so I'm not sure if it was tightened too much bent them, or if the head was not down over them all the way or what. I think bottom line I must not have had the torque set right. I ordered a stud extractor and new stud but it will be next week before it shows up. Always something.
