Rebulding FD in the Midwest

Post by duegi »

Looking for a good shop in the Midwest, either BMW dealer or shop that works on BMWs, who is capable of working on the R1150R FD assembly?

Frankly I don't trust my local BMW dealer to get the pre-load on the big bearing correct. I'm not crazy about spending the money to have the FD rebuilt then have the big bearing self destruct in 10K miles due to the wrong pre-load...

What was the diagnosis on rear wheel play again, loose at 3 & 9:00 says what VS loose at 12 & 6:00 means something else???

Laxity at 3 and 9 indicates Paralever pivot bearings. If your fd bearing is going south, you ought to have discolored gear oil evident when you drain the housing. Do some investigative work. My pivot bearings were bad at 14k. I cannot explain why this happened and can only assume they were not properly seated and torqued at the factory.

The large seal, towards the wheel, has been misting fluid onto the hub of the wheel for a while. I've been changing the FD fluid every 1k or less to track what's happening. I'm running Royal Purple in the FD and Bel-Ray red in the transmission to make sure I don't have something else going on..

Problem is the leak is so slow that the oil color is difficult to detect so I'm assuming it's the FD.

I've got another FD that I can change over to. Perhaps at this point I should just change the seal on the problematic FD. Hence the initial question regarding a good shop to work on the FD that can do the pre-load correct the 1st time around if I have the big bearing replaced.
