Re: R1100S Paralever/swingarm play @ 30,500 miles

[Bob Hadden <kbhadden@xxxxxxxxxxx>]

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.

If you have gearing play at the back wheel (as opposed to the swing arm 
pivot), you need to replace bearings, I believe.  I think the only 
needle bearings are at the drive input to the rear gear set.

Get the Haynes.  It has the best pictures and test on this.
