Pinion Shims

Removed the pinion bearings from 2 different pinions (one a '65, other '66). There were no shims under the bearing of either pinion. Wondering how often people see no shims at all.

It's not common. I have seen first hand what happens when the pinion gear gets loose on the pinion shaft. It will walk the pinion bearing enough that the shim spins and comes apart.Check to make sure the gear isn't loose.

When the bearing spin there is usually a tiny ring in what was the radius of the inner race. I have seen that a few times so I always use some green Loctite on that bearing.

The only time I didn't find ring and pinion shaft shim were on two PG pinion shafts.

BTW - you do know the 65 ring and pinion shaft is too long to use in a 66-69 differential.
