R1100S Paralever /swingarm play

["conrad long" <conradlong@xxxxxxxxxxx>]

Jack,

     Bob is correct; they are tapered roller bearings, both at the swingarm 
and at the final drive, at least on my '94 RS. Any side to side movement is 
bad; sometimes the bike moving on the centerstand can mask real results of a 
check. IIRC, they are preloaded to 7Nm with the large allen bolts. I've 
found a couple that were "notchy" at 40k miles , but never loose. Did the 
bike feel "loose" when you rode it? You also hinted at a noise: ?

     I've never taken the preload adjustment to be routine maintenance, 
simply the procedure to use when re-installing the swingarm/final drive. 
Sorry, can't find anything on the IBMWR site for oilheads, but I agree with 
Bob, the Haynes manual is good. Best of luck.

There are two pivot points on the rear paralever/swingarm: one very
close to the final drive, i.e., just before the boot and the other at
the frame attachment point.  I thought that the needle bearings were in
the pivot point closest to the final drive.  Is that correct?

It now appears to me that the entire paralever/swingarm is moving as a
unit when "check" it.  The free play seems to be at the
paralever/swingarm to frame pivot point.  I have tried unsuccessfully
to find a procedure for checking or adjusting the swingarm bearings or
their preload on an R bike but have been unsuccessful.  Does anyone
have one they could post?

The Haynes manual details this procedure.  You should have zero play in
the bearing systems in the rear drive area.  There will be lash in the
gear set, but that is a different thing.

At the front of the swing arm, the bearings are placed by the large
allen sockets and locked in with the large nut.  These are located
right by the foot  pegs.  I believe the bearings were tapered roller
type.  The allen sockets are put in with lock tite that you have to
heat to break loose.  Not using heat coud cause thread damage so don't
skip that step.  I think this is also on the ibmwr site as part of the
spline lube article. Snip>
