    R1100 Final Drive Question

    old info but still current. thanks all. going with the LM47...

    I cracked the FD on my 99 R1100S open and bearings, races and gears are all good but there was some play. does that make sense? or am i missing something that has added up to this play?

    one other question - if there are 2 shims in there - does that mean this was shimmed by previous owner? bearing has 19 balls. fludi pretty clean and no metal aside from norm.

    (sorry if i may have hijacked a thread and the pic is huge...)

    Gear backlash (normal) or bearing looseness (axle or pinion)? Be sure to place the thicker of the two shims towards the face that has a slot in it. Two axle bearing shims are normal.

    May be a good time to arbitrarily replace the crown bearing and check the preload anyway.

    To achieve the proper preload, a combination of shims may have to be used. It is not an indication of someone else in there later.

    Here is the list as per MAX:

    As far as checking the shimming goes there are few ways to do it.
    Google it and you'll find lot's.
    I prefer to use the solder method. It has worked well for me. I have re-shimmed quite a few now with no issues.

    The 19 ball bearing is the latest.

    For reference, the switch from the 19 ball FRA or FAG bearings to the 17 ball SKF bearing was only temporary - it lasted about six months. I believe BMW was investigating the quality of the bearings they were receiving and switched until they were satisfied that failures were not being causesd by bad bearings. They soon switched back after a few months.

    Now that explains a lot! Thanks.

    thanks, all.

    1 - I have a few sale shims on order from MAX and will advise when this is all back together. should be simple, hmmm?

    2 - I have yet to find the solder technique. I tried the dial caliper/heated cover/slide the crown assy/bearing up and down technique but the readings do not add up.

    3- the thicker shim goes on the outside of the assembly next to the cover, right? that is where the machined groove is, I believe.
