I need to replace my pulley tensioner bearing but i do not have a maintenance manual yet for my 2002 M2. I have taken the cover for the pulley off and have taken the tension out of the belt by loosening the tension adjustment nuts on the rear axle assembly. I have also taken the hex bolts out of the pulley itself.

I'm not sure where to go from here to actually take the pulley off? I'm not motorcycle mechanic but general engineering principals say there are only a few ways to attach a pulley to a shaft. Is there some sort of keyway that holds it on? Is there a set screw that holds the pulley on? I don't want to just start prying on it and damage something.

Any help would be greatly appreciated.

What do you mean by pulley tensioner bearing?
The M2,like every tuber, has no pulley tensioner and because of that no pulley tensioner bearing!
The XBs do have a belt tensioner.

P.S.Beside a good nut and a reliable long armed torque wrench (near to 300Nm),heat is the secret to remove the sprocket nut.

I have removed the pulley and am now looking at what will probably lead me to taking in the bike to the dealer. I think my terminology was wrong with "pulley tensioner bearing". The bearing that i need to replace is the bearing that is on the drive shaft directly behind the pulley. I realize that the tension in the belt is taken up by adjusting the nuts on the rear axle therefore not needing a tensioning pulley.

But now i'm looking at a bearing that appears to be pressed onto the drive shaft and i don't think i have the right tools to do the job.

This info is for an S1, but the basics are still the same.
