I did replace the swingarm bearings. Now puttings things back together. The cardan shaft goes onto the gearbox spline. Is it just loose on it, or is there a lock spring? In that spline that is coming out of the gearbox, there is a place where a lock spring could be. I can't find it in the partslist. Should there be one? What size?

Something like these snap rings:

Paul, it's an internal circlip n the splines of the front yoke. You push the yoke on until it stops and then give it a whack to get it to slip over the end of the output shaft and engage in its groove.

I'll try and get some pics. There is no separate part # for the internal circlip.

Thanks pete.

I tried it, it slides on, you push it again and it moves 8mm more on it. so the thing must be there. And then it lock when you try to slide it off.  But in the grease I could's see it.

Swingarm bearing 50.000km. I suppose when serviced much earlier it could have been saved.

And to get it out with home tools. I went out to see if a better puller was available, but there is very little to choose from. Else then the +1000$ tools. But got it out nice. It's not a high tech job but takes a lot of time with taking all things off.

There are reliefs for the puller jaws at 3 & 9 O'Clock from memory but because there is nothing to *Push* on you're a bit stuck! Your solution is ingenious but the puller jaws should of been in the reliefs.

Me? I cut the buggerance out of the race with a dremel tool and whacked the remains out from the other side with a bent marlinspike! Laughing best solution though is to grease the buggers properly early on. Do that and they should last forever!

The jaws are in the reliefs, that's the only way to get grip.

I've shrunk bearing cups in a wheel hub with a bead of weld, but I would be too
chicken to try it in that situation , that's a great tool invention Paul .
