1200gs rear axle removal

[birdseye]

wheel caliper and mudguard thingy removed. I want to get at the crown wheel bearing.

do I have to remove the circlip which holds the disc carrier to the rear hub or can I split the rear bub by undoing the bolts which hold it together and without removing the disc?

how are the black plastic covers on the rear axle held in place? Do I just pry them off?

Hi there is loads of info on here, do a search of FD and final drive, you will pull up loads of info and drawings.

had one search before I posted padz and found nothing. had another and got an answer to the circlip thingy but still no answer to those black trim plastics.

hoping someone on here who had already done the job could advise - got to be easier than going through dozens if not hundreds of threads to find the answer.

The whole final drive box has to come off the bike. There is a recent post on the subject. Just scroll down a bit.

I give up! I cant see the answer to my question and I've been through every final drive post in the last 10 pages or so. I'll take the bike to the dealer and he can sort it.

Try this - link. stripping out the final drive's not that easy without the right tools and equipment. There's a couple of people on here who rebuild them. Try looking in the vendors, might be cheaper than a dealers.

the plastic cap will pop out with a small screw driver,i would advise against trying to strip the fd unit unless you have access to a well equipped workshop,you will need a fairly big hydraulic press,air impact wrench,special tools to remove the pinion bearing ,a means to heat the unit to @100 degrees,and a good idea of what you are doing,i have had to salvage quite a few of these fd,s that have been damaged by home mechanics and other bike workshops

I was recently talking to a BMW independent mechanic. He replaces the main wheel bearing but doesn't replace the smaller inner bearing. He also had no idea about the pinion needle bearing being weak or that it changed from 2006 for a larger size.

I won't name names because I didn't really quiz him but It's highly likely that many general mechanics don't do FDs properly. Then we wonder why bearings fail again soon after.

Take it to a specialist.

i agree (but i would really),the processes involved in rebuilding a fd are rarely used in a bike workshop,it is more akin to car transmission rebuilds and general engineering workshops.i have seen fd,s that have been stripped by hammering them apart,distorting the wheel hub etc.not good
