The F-D I got from Motorworks is basically in good condition. Splines, pinion and crown wheel are excellent. Among the stuff I got from the Police when I bought the bike were the crown wheel input roller bearing and the big crown wheel output bearing (OEM), as well as an output seal. 

Since the big roller bearing has developed slight roughness and a tiny amount of a play, I decided to use the opportunity to change both bearings and the output seal, as well as paint the housing and tidy everything up.

When I pulled off the roller bearing I damaged the adjusting shim behind it. There should be no need to re-shim the drive if I use the OEM bearings I have got, the big original adjusting shim (nr. 2 in diagram) and the same thickness shim (nr. 4 in diagram) in place of the one I damaged.

When I measure the damaged shim with an accurate Calliper,  I measure it 2,360 where it is thinnest and 2,400 where it is thickest. From this I drew the conclusion that it originally must have been 2,400.

Sounds entirely feasible, though the bmw workshop manual section 33 pages 14 and 15 will help clear the possibility that there is variance between the old and new bearing, allowing you to check backlash.

The Clever are adept at extricating themselves from situations that the wise would have avoided from the outset - QUOTE from david Hillel in Out of the Earth.

I have the BMW Manual, but only in German. Unfortunately I don´t understand a word in German. So if anyone has these pages scanned in his/hers computers I would really be appreciate if the same person would come forward.

I have a "new" drive with excellent splines and a mint shaft. Both will last "forever" with proper maintenance. It would be a shame to mess it up.
