Tom Endy: Transmission Bearings (Hyatt style)

[Greg Jones]

I rebuilt my transmission about a year ago or so using the hyatt roller bearings from the vendors. After a couple hundred miles the tranny has a grinding noise while idling in neutral. Having read Tom Endy's warning about inferior bearings that were on the market, I suspect that is what I installed.

So how can you tell a good bearing from an inferior one? I believe Tom mentioned that the roller should be riding on an "axle' or shaft of its own and the ends not riding in a crimped depression, or something like that. I have attached a picture of a new bearing obtained probably a couple years ago from Brattons, and pictures of bearings taken out of an original transmission. Notice the repro on the ends is markedly different.

Tom Endy, please help edify me as to the best bearing source and whether the repro I am showing is "good" or "bad." I want to redo this transmission only once.
