    1994 R1100RS final drive pivot bearing replacement

    Is there another source for the final drive pivot bearing besides BMW? Also any hints on replacing them?

    Sadly no, FAG has an exclusive supply agreement with BMW.

    Just replaced another a set yesterday, $115cad each from BMW dealer.

    Robbery pure and simple for a poor design.

    Make sure you preload correctly for maximum life (7nm) with a known accurate torque wrench.

    Just a heads up.... the Nylatron aftermarket bushings don't even last as long as the bearing. I have an associate that has gone thru 2 sets and gave up.

    Those bearings are a bad design in my opinion.

    I would try the "Nushings" rather than going with the originals: http://advrider.com/index.php?thread...150gsa.1116193 I have a set in my emergency FD kit ready to go but haven't installed them yet. The design has gone through a few changes based on user feedback and seem to be the best solution.

    You can also go with the Rubber Chicken bushings. http://rubberchickenracinggarage.com/bushings.html They are Oilite bronze. Rubberchicken recommends lubing with Honda Moly but I think that is a bad idea - just leave them alone - that's the whole point of Oilite.

    See my comments on the "Nushings"

    From my experience the stock bearings are still the best of the 3 and that is not great. The slightly larger ones on the transmission side never have issues. BMW should have used those although the casting would have needed to be a bit chunkier.

    If you very carefully pack them full of silicone grease, not silicone dielectric grease, silicone lube grease, no air anywhere they seem to last a lot better. If you can reach in after install before setting boot and pack the gap around them full of more grease then better.

    Never ever use moly on oilite bushings. It plugs the pores.

    Soak in motor oil if you want. I think a few days in Mobil 1 5W30 is good.

    There was a thread in ADV a while back on those.
    They were pretty new then. No feed back IIRC.

    I have the bronze oilite bushings in my R1150R and Voni's R1100 RS. They work fine when properly installed and lubricated. There was an early issue with the interference fit but that has been corrected.
