Does anyone have a link to any discussions on final drive shimming? I've found lots of final drive threads, but none that pertain to shimming, measurement techiniques and the potential for incorrect shimming from the factory.
I pulled apart my spare 1996 R1100RSL final drive yesterday. It is relatively low mileage at just over 20k, but it was stifff to turn relative to the one in my 1995 R1100RS. It also had a slight leak at the output seal, but turned smoothly and the bearings seem to run fine with the cover removed. My first stab at measuring the preload came out to 0.20 - 0.25mm of preload which is a bit much in comparison to 0.05 - .010mm called out in the manual. I intend to repeat the measurement using a different technique that I found linked from ADVRider.
There was also discussion of using soldering wire to compress in place of the shim(s) to get an accurate measurement of the gap between the bearing and the housing from the deformed solder wire.
The links took me to a video from CharlieVT on the bmwlt forums:
I was hoping to find some comments here letting me know whether or not I was headed down the right path, but my search results didn't get me anywhere. Any thoughts or links?
