Paralever Re-Build.

[andy white]

Hello Everyone,

I am in the middle of re-building my bike after excessive longitudinal play was found in the back wheel. I have had a good look on here and ADVRider on how to do this.

I had previously adjusted the paralever bearings to remove any play. This proved successful for around 1000 miles when the play returned. I decided to pull the rear gaiter between the bevel box and paralever back to have a look inside.

Water had been entering into the shaft housing through the front gaiter, which had fecked the bearings

I decided to replace the paralever, bevel box to swing arm and final drive bearings, looked them up on the net and ordered them.

I fitted the new paralever bearings this morning and the re-build began;

I have now got to the stage where i need to tighten the Left hand floating stud to 7NM (right hand fixed stud is torqued to 150NM).

But I can wind the Left hand floating stud all the way in by hand until there is no thread left on the outer casing for the locknut and there is a lot of play in the swingarm even if i torque the Left hand floating stud to 7NM.

My Question is;

Is there something i am missing?

Is there something that i should check?

Im going to remove the swingarm again and check i havent damaged something.

Any info will be greatly apprieciated

:

Yes. Very simple = It's a taper bearing and you've put it in the wrong way around.

What is that exhaust can under the swing arm?

Looks like one from a car.

Hi Everyone,

I have sorted the bearings out now, I had fitted them both the wrong way round

All re-built and play free

Thanks for the info everyone, it would of been a nightmare with out.

Hi Andy

I found some play on the rear end, paralever, thought that I would try adjusting up, but on looking the bearings feel buggered. The question is how do I remove the bearings?

Cheers

Find a socket the right size to use as a drift (must seat on the outer race), sit the socket on the bearing from the inside of the swingarm, insert a 6" socket extension through the other bearing into the socket you've just positioned, hit with hammer (supporting the swingarm on a bock of wood just next to the bearing you're drifting out).

Thanks for that Mat, just wanted to make sure, never done these before and didn't want to use the usual heavy hand approach and regret it later

Thinking about it, I've only ever done this with the swingarm removed (drifting the bearings out and in). It's quite possible to change the bearings with the swingarm in position but it's probably better to try and fabricate a puller from whatever you have available (sockets, washers, threaded rod etc). Perfectly possible to drift them but you'll probably need help to support the other side of the swingarm with a heavy dolly to absorb the shock.

I found it Easyer to remove the swingarm, if you do a search on ADVrider.com there is a writeup on the whole procedure. To fit the new bearings I put them in the freezer first whilst I cleaned and greased the housings on the swingarm. Just make sure you fit the bearings the right way round, or you will have to do it twice like me
