Just rebuilt my 1936 Pickup tranny, which was a 1939 Mercury car tranny.

Replaced all of the bearings and synchro parts, along with the front and rear second gear thrust washers, etc, etc.

After installing the bearing retainers and checking the main shaft end play, I have about .062 of end play.

Anyone know what this should be? I have searched endlessly for a spec on this through all my ford books, motors, and the web, but can find nothing on the end play. .062 seems a bit large, and as these transmissions have a tendency to pop out of gear, I'd just as soon fix this while still on the bench.

It looks like a lot of the end play is the rear bearing sliding back and forth in the rear retainer. The snap ring is .067 as opposed to the original .065. The front thrust washer was pounded to death when I pulled it all apart. Likely this was why.

Anyone got any ideas? Can a shim be put into the rainer to hold the bearing in place?
