Final Drive OH

[NW Trails]

Long time biker, First time BMWer owner (Love the ride!), First time poster.
2006, 25K miles. Modest leak on the final drive. Mechanically inclined. (OH'd a few engines that still ran afterwards.) Decided to replace the seals myself. I'm guessing that because this was "never supposed to happen" the Hayne's manual doesn't cover the job.
Anyone here ever done it? Suggestions? URLs? Traps? Anything else I should do while I'm in there.
TIA for any help. Love the forum.

A lot of info in the last couple of years.

Start here with Mr. Google: youtube BMW R1200 GS Final Drive Repair

Welcome to the forum.

Edit...http://www.maxbmwmotorcycles.com/fic...0&rnd=03252011
This is off the parts Fiche from the Home page on this forum.
Click on 33- Rear axle and suspension.

2nd edit....If your to the grinding and terrible noise condition guys usually will replace the "07 Grooved Ball Bearing". The current part number is a
little mystical so I have to defer to someone who has been there done that, which is above my pay grade.

That video is for the older version of the final drive. The version on our GS have little in common other than basic function. Some of the differences include:

* needle style roller bearing vs tapered roller bearing
* Big bearing in the gear oil vs big bearing not in the gear oil

The issue of setting the appropriate pre-load for the tapered roller bearing, for example, doesn't exist on the big hole FDs as there is no tapered roller bearing.
