I am just replacing the pinion bearing in my Chummy axle and the new bearing for the rear of the pinion (ie just forward of the gear) differ from the original in as much as it has no method of confidently retaining it in place.
The outer race of the old one had a smaller bore at the forward end and hence would not pass the rollers and drift into the diff. The new one doesn't and whilst it was a good interference fit in the torque tube, and Loctite bearing adhesive used abundantly, I cant decide if I should take it apart again and perhaps fit an oil thrower between the bearing and the pinion gear. the thrower being of sufficient diameter to impede an errant outer race attempting to a approach the crown wheel.
I wondered if anyone else has a tackled this before ?
Any advice welcomed.
