Got a new rear bearing and got back on the transmission a little yesterday. After polishing the shaft mating area I had about .002 interference fit with the new bearing. I honed the inner part of the bearing down until it was around .001 interference, set my heat gun on the inner race awhile until it got up to 200 F and then started it on. Still pretty snug but an least when I tapped on it with a brash punch and small hammer it was now moving so after what seemed like about 60 to 70 punch strikes all around the inner hub it was on. The rest of it went pretty easily. The sticky green transmission assembly lube really holds those rollers in place so no issues after all this time with the countershaft.

I did note that if I screwed the 1-2 screw that holds the detent and spring down tight under the top plate - it was locking the fork/shaft up from sliding. So I had to back it off about 1 to 1-1/2 turns before it shifted freely. The 3-4 and reverse all seemed fine. Good idea to check that everything shifts good and spins fine before buttoning up.

Just have the gasketed parts to assemble and it should be ready to go.
