I have completed the batch of 38 diff. side covers. The pot joint and yoke type both take the same bushing. They are all used so they were dirty and most had gasket stuck to them as well as dry seals and worn bushings. I removed the seals and pressed the bushings out. Scraped gaskets off followed by cleaning in tank with stiff brush. Once blown dry I removed all paint with stripper. Some of the pot joint type had been abused in the seal area. Had a couple welded and dress those and others in the lathe. Glass beaded all of them, followed by a good cleaning with SOS pads in hot water. A light wire brushing followed by spraying with brake clean before pressing new bushings in place. Using a very clean racing gear case I snug the diff housing bolts pop a pair of side covers in place then torque the three bolts either side to secure covers to diff. housing. Then remove the bolts holding diff. housing to case and hone the bushings using a king pin hone in a Sunnen honing cabinet. There is roughly .006 to come out of bushings to reach zero clearance and I finish at .0011 to .0015. I don't have 38 seals so I won't put new seals in yet. Changing covers and dressing stones I was able to hone four sets an hour. I have kept up with my time spent on this project and will figure what it cost per set. Only needing two sets now I should have a long term supply. I'm not sure everyone does side covers with a tranny rebuild. I have and will continue to as it's another leak area addressed. Steve (CTR)

I have done a few side covers in a batch and before that I did a pair one at a time. Weather you do them in a mill or a lathe there is a a lot of indexing. I have taken to doing them in pairs. I bolt the sides to a diff. housing and hone them together using a king pin hone in a Sunnen rod machine. The dial bore gauge is marked in tenths of a thou. Careful stroking and flipping end for end keeps the stones true. 

It turns out I only have 38 prepped and read to hone. Eighteen are early yoke type and the balance pot joint type. Getting them really clean is a lot more work than you'd think. Steve (CTR)

Steve,
    This for a A+. I've replaced both the bushes on the differential case & crownwheel and then bored on the lathe to size (Slip fit) .001-.002. I am contemplating making bushes for the planetary gears as the ID to the new shaft is pretty bad. I did put it all together and when all snugged it up it is actually pretty good. Thoughts? I also have bushes for the Diff side covers for pot joints, but just have not gotten to that point yet. Any guidance ya wanna send my way?

You mention 4 synchro but not pre or A+. I have measured a bunch of the larger ones and they seem to all mike the same. I can understand one and done. I'm going to spend the day prepping A and A+ diff side covers for yoke and pot joint. I have degreased, stripped paint, pressed out bushings and glass beaded maybe 40 total. I will scrub each with Brillo pads and press bushings into as many as I can today. The ones with slight damage in the seal area will either get dressed in lathe or welded and dressed. Then all will be matched in sets and aligned honed to size. Steve (CTR)

Steve....Yes I do. I might be able to get by with a .130-.132 on the small end to get into spec. Just curious how much the large end has worn & if I should replace it too.... Gearbox is all broken down, only wanna do it once. Thanks.....

You do realize it is the smaller one that comes in different sizes? They range from .123/.124 to .130/.131. Don't know if this helps or not. Steve (CTR)

Working on the laygear installation......Setting endgap to .002-.006" I'm at .013", checking my large thrust washer is at .1245" . What does a brand new one measure to? Anyone happen to have this information?
