One of the weak links in the paralever drive train is the final drive pivot bearings. These bearings are composed of four components:

1) Outer race that installs in the final drive housing

2) 20ish needle bearings

3) A plastic race that holds the needle bearings in place - this is the part that usually fails and is the weak link

4) Inner race that holds 2 & 3 in place

The BMW part number is 33172311091 (about $118 USD each new from a dealer.)

I had a spare good plastic needle bearing retainer ring and some needle bearings on hand so I assembled the following, using Mobil 1 synthetic bearing grease to hold the needle bearings in place:

Then I pressed it (by hand) into the outer bearing race and then inserted an inner bearings race. Voila! The finished product:
