1994 R1100RS final drive pivot bearing replacement

[coltself]

Phone Ted Porter at The Beemer Shop --- get the Emerald Isle Paralever Pivot bearings/bushings. I've installed them in my 1999 R1100S and my 1995 R100GS-PD with very good results. Have tried the Bronze Oillite Bushings, but found them to become galled and useless in less than 10,000 miles. The Ei bearings also have a zerk fitting so the bearing can be re-lubed without removing the Final Drive unit.

Does anyone have any comments/experience with Chris Harris's torque for the OEM inside paralever bearing (10-12 ft lb)??

I don't set mine to a torque, but rather for the absolute minimum detectable CLEARANCE in the bearing. I use my fingertip across the bearing to measure the clearance. I feel it is too easy to get the bearings preloaded excessively as the jam nut is tightened. Tapered roller bearings can't resist much axial preload force - especially when the taper angle is as shallow as these bearings are.

Steve.......do you have an update on the EI Bushing installation you performed earlier this year?

As a matter of technique I apply medium strength (blue) thread locker to the pivot pin threads and allow it to cure for about 30 minutes. Then I tighten the lock nut without thread locker. I paint spot the pin so any rotation can be detected. Using this procedure the pin does not turn when tightening the lock nut.

First I need to remember which bike I put those on

( just looked down page to see it was H's 1150...many miles since and all seems snug and fine)
Just recall effortless install

Good looking stuff. I've gotta '94 R1100RS. Been sitting neglected for some years. I've gotta a lotta work ahead of me to bring it back. Those bearing/bushing upgrades may be a part of upgrade process. Thx guys.

Thanks for the reply Steve
I have a set of these bushings for my 1100 RT and will be installing them this winter as part of my off season maintenance regime. I did have a set of the bushings from Rubber Chicken Racing and they lasted about 50K before they started to show wear so I’m looking forward to trying these

And Paul, that’s a great idea with waiting 30 minutes or so with the blue loctite. I may try that as well
