Hi

Well I just about finished installing a new sator and rotor.

Put in the plate for the clutch adjuster and was cleanin out the rebate for the circlip when I noticed what looked like a crack.

I rubbed a little grease into the rebate then wiped it out, a pair of close up glasses and a torch revealed a crack almost half way round, a little bit of pressure from a small screwdriver opened it up easy, then broke off.  The diferent colours on the broken face indicated that it had been cracked for a while.

This area is flimsy to say the least concidering the froces exerted by the clutch pushrod, I thought HD made things stronger than needed, fuck the effort needed to get that bloody comp nut off would indicate the they do.

I'm glad I spotted it now instead of it self distructing at speed out on the road.

Any one heard of this before?

Now I'll need to make another tool to compress the spring, only the ones I've seen use the clutch adjuster hole to screw into.  Only thats gone now. So I was thinkin of attaching to the outer starter sprocket.    Any Thoughts?

Thanks Dug

Take the clutch hub off and compress it the clutch pack than remove the cir clip than seperate the clutch hub/pack parts you need a press or make the tool with a hole to go through center of hub with thread rod to compress the pack 

I've got a crack in one of my bikes hubs has been there for about 6 years that I know of the worst that would happen is no clutch and the adjuster plate would fall into the bottom of primary

Hi Perthhog
Is the crack on your's in the same place?
The worst? I think maybe the "worst" might be bouncing up into the chain getting caught in the sprocket teeth, locking the back wheel while cranked over in a corner, reaching for the clutch then realizing there ain't one with a 100 metre drop on the edge of the road..... yehaaa ride em cowboy

Yes mate same spot only about 1/2 of what your is though My peace is still attached though

Hi

I've been giving the subject some thought.

The generaly accepted spring compressor uses the hole in the clutch adjuster to attach to.

If this was tightened down too much, I think this may be the sourse of the problem, it isn't a robust part, they have a thick bit of steel then a circlip pushing against a few mills of alloy, just doesnt look adequate.

I supose there is a better part out there, but I"ve got the new part on the way.

What do you think of this?  It would mean I dont have to pull every thing out again.

Your over thinking it it not that hard to to remove it all 2min work seeing you all ready have the outer cover off And as for being a week part I put the crack in mine
With a socket as clipped the edge when I was undoing the hub nut the socket cocked sideways slightly and rattle gun power one in my case.

Hi
Wow, two minute's, you're fast.
Yeah I do tend to over think things.
I don't want to pull it apart all over again, I found adjusting the chain tension fiddley and I'll need a tool anyways.
Thanks for your reply's
Doug
