Hi everyone,

I'm doing a spline lube (all driveshaft splines appear perfect - bike has done 36,000 Miles) and have eventually removed the RH pivot pin (just decided to use a blowtorch for 10 minutes protecting the final drive with a fibreglass heatshield with a hole in it mounted on the pivot pin). Crikey that Loctite is designed to be permanent or what!!

I now find I need to replace the pivot pin tapered roller bearings on the final drive (not the swing arm). I suspect the RH pivot pin was torqued slightly too high and there are marks/indents on the inner race which I can feel with my finger nail.

I have looked at http://www.k11og.org/forum/viewtopic.php?t=1097 but just wondered if anyone had done this job recently and had similar experiences i.e. no need to use any special tools other than some heat and a socket/extension bar to drive out the inner races

Thanks in advance

Tony

Tony,

I just replaced the Paralever pivot bearings this winter. Not a difficult job. I recommend reading Paul Glaves article in the October 2007 issue of the BMW MOA Owners News. He provides good instruction for perfoming the removal and installation of the bearings. I chose to replace the needle bearings with the JL Enterprizes bushing kit. The engineering made sense to me. Take your time, be methodical and you'll have no troubles. Good luck.

The MOA appears to focus on riders in the US (no surprise there !)

Is this article available online anywhere - the MOA site does not have a search function (maybe this is only available to members ?)

Correct, the search function is disabled unless you login. Here is one of the threads mentioned....

Thanks guys - the bearings came out easily with a socket and extension bar and a few taps - following reasonably gentle heat from a heat gun.

From other forums looks like these should be standard FAG bearings - but they are BMW specials - and priced to match!
