So I just want to give an update on how the repair went.
Problems: When removing the six bolts holding the inner tub to the spinner hub, five of the six broke, which I believe is the new record. Since most broke by just having the heads break off, the tub was still wedged to the shaft hub and would not separate from it at all. At this point I flipped the whole thing over and used a 1.75 inch socket on an large impact driver and took off the nut holding on the outer tub. Then I had to put a block of wood on the end of the shaft and give it a few smacks with a hammer to get the outer tub off. I tried to do it the right way and use a bearing puller to pull out the outer tub bearings, but neither one would budge. I ended up taking a two foot length of iron pipe and pounding out first the inner one with the tub upside down and then turned the tub over onto a couple of block of wood under the bearing area and pounding out the outer bearing from the inside. The wood was necessary to elevate the plastic parts of the tub from the floor, in effect keeping the impact just on the metal parts. Both bearings came out rather easily, just went slowly and evenly around the bearing, making sure not to let them get too crooked. Back to the inner tub, I use a very thin pry bar and slowly separated the hub from the tub, with no breakage. At this point I will give a bearing update, the two outer tub bearings were not that bad, both had a lot of rust on them, but both still spun rather smoothly. The tub seal was in horrible shape, but that was expected. But the real disaster was the two bearings in the spiiner shaft. When I turned that it sounded like gravel, so I had to replace them both also. I put a block of wood on the top of the shaft and pounded out the bottom one which came out stuck around the shaft. I then used a bearing puller on the upper bearing and it came right out. I then pounded off the bearing stuck to the shaft with a length of one inch diameter iron pipe, and it came right off.
On the the spinner shaft hub. I could not get the broken bolts out no matter what I tried. I used various broken bolt extractors with no success. So I decided I would have to drill them out. Well that did not go too well. I was using a drill press, but even with that the bit would not stay on the bolt, it would keep slipping off to the side, so no luck there. I then decided I would drill them out from the back side and just put the whole thing back together with bolts with nuts. Well that did not work either, once the drill bit hit the bolt it would slip off to the side. For being such tough bolts, they sure broke easily enough. At this point I was a little ticked off, so I decided to go barbaric on this thing and took a 1/8 inch drill bit and drill many little holes around the bolts, gave them a little smack with a hammer and they were finally gone. The holes were a little bigger, but that was nothing a few washers would not fix. I am not recommending this method by any means, but I have no machine shops around here to take it to, I had to do this myself, and I was on a clock (family needed a washer, four daughters). So, to be clear the part the the bolts screwed into was now gone, and I would have to use nuts on bolts to join the parts back together. I ground the back surface, where the nuts would go, smooth with some grinding wheels.
Clean up: I scrubbed out the tubs, the spinners, the transmission until they were all clean inside and out. I wire brushed the spinner shaft and inside all areas where the bearing were to go. I pried off the metal part of the tub seal that stayed on the hub, which incidentally was hard to see. All the corrosion in that area made everything blend together. I only found it by taking apart the new seal so that I could see what I was looking for. Then I wire brushed the whole spinner hub until it was clean, especially where the trans seal went and the tub seal. The part that rode inside the outer tub bearings was very clean and required no clean up at all.
Reassembly: The first comment I want to make is about bearings. My machine used the thick one way bearing on the bottom of the outer tub, however it also had the recesses for the white plate with the one way bearing in it that comes with a new clutch pulley assembly. If your tub has two big notches on either side to the large 1.75 inch nut on the bottom of the tub, you can also use the white plate. So I lubed up the bearing and installed the inner tub bearing of the outer tub first with a bearing installer, in retrospect, this was the hardest one to install due to the fact that it cannot be seen while installing it. Be very careful to keep it straight and level. I then flipped the tub over and put in the spacer sleeve(also well lubed) and installed the outer bearing (well lubed). I installed both of the spinner shaft bearings(more lube) into either end of the spinner hub by starting them with a bearing installer and finishing up with some impact sockets of the exact diameter to seat them into place with some gentle tapping. I then lubed up the spinner shaft and inserted it into the bearings. Now to install my modified hub back onto the inner tub. Just for fun I ran a bead of black silicone gasket sealer around the edge of the hub, and set it into place. I then used 5/16 inch bolts, a flat washer, a rubber washer, through the tub and hub and another flat washer and then a lock nut, all stainless steel. Bolted it all up tight and even, we will see how it holds up. Time to put the outer tub onto the inner tub. First I lubed up all the bearings and bearing surfaces with synthetic water proof lube, installed the tub seal and tried to put it together, but it would not go. I finally had to separate the tub seal sleeve from the tub seal, push it down around the spinner hub, and then install the outer tub. That worked great, it went right together. I had to use a large spacer washer (m36 zinc oxide) on top of the outer tub bearing to make up for the size difference between the original unobtainable bearing and the replacement bearing. I then threaded the large nut back on the shaft, but could not tighten it, everything kept spinning, so I gave it a few turns with the impact driver to snug it up good and tight. I then put on the white disk with the one way bearing, the shaft that goes between the two bearings and the clutch pulley and bolted it on. I then put the tub assembly back into the washer. The rest of the assembly was by the book. Install the trans o-ring, well lubed of course, the trans, the spinners, etc.
Test: Started it up, ran through the diagnostic quick wash and spinner test, and could barely hear the thing spin it was so quiet, Wow!. No water leakage of any kind. Ran a few small loads through it to check it out, since that is what it would not wash was small loads, and it worked fine.
Parts:
1 Tub Seal 25001090

1 Lower shell shaft bearing SCE-910
1 Clutch Pulley 25001169
1 M36 Zinc Oxide washer
Synthetic water proof lube
Retrospect: If you are going to do this job, plan on doing all the bearings, if one is bad they are likely all bad, and once you are into the machine this far, you might as well go all the way. Second, I am not sure why the inner tub has to be taken off of the spinner hub. The bolts are going to break, and ruin your day, and I believe everything can be replaced with those two parts left intact together. Just take out the whole inner/outer tub assembly as a unit, with help of course, flip it over and remove the large nut on the bottom and separate the two tubs. Everything can then be replaced at that point. The work inside the inner tub will be a little tight, but I think it would be better than the aggravation of breaking off all the bolts. I believe it is only recommended to take it apart by removing those bolts in the service manual because it states to replace the whole outer tub instead of the bearings, and probably the service technician is not able to lift out the whole assembly be himself.
Follow-up: I have washed more than twenty loads with no problems at all, very quiet, no leaks, no stains left on clothes. So far my modified hub has caused no problems. All is well, good luck with your repair.
