Back in the shop and the clutch rattle that seems to be getting louder was my focus of attention today. I wanted to check the torque on the clutch hub nut and I figured it's a good time to check out the condition of the clutch (at 6k miles) since some of you crazy peeps have been wearing them out, and to dispel some of the myth of the quick shifter as well.
They are really good!
I believe 46.3mm is minimum for the clutch stack

Steels aren't blue at all

The nut was plenty tight, and had it's red loctite on it. Not bad for #24 built haha.

But of course you can't take it off without stopping the inner clutch hub from rotating, and that takes a clutch tool. I have one, now where did i put it? Hmmm...
Oh ya! I sent it to a forum member (maybe not even this forum...) a long time ago and I guess I never got it back. I have since cleaned out my PM's so theres really no recourse. That sucks and all, but now the bike is apart and it's too early for beer.
I'm undecided whether I should be proud or ashamed...

Lets go with proud, because it worked flawlessly!lQNxgP%FTn6m%f0Gm6TMiw by Cooter!, on Flickr
If you decide to be as dangerous as I am with a welder, I'll expect my royalty check in the mail promptly!
An important note: If you decide to do this, remember you are NOT clamping the fragile aluminum hub AT ALL with the vice grips. Close them just barely hard enough to stay shut. You are simply stopping it from rotating, so the tabs need to be straight and fit in the slots well.
I even used the slots near the extra casting to be sure i wouldn't warp it. Stuff gets expensive in here real quick...
So now that I have successfully re-torqued the Clutch hub nut to 150ft/lbs instead of the factory recommended 125 (whatever, man), and happy with the condition of the clutch time for an easy re-assembly.
EBR has conveniently labeled all the stuff for the slipper clutch (ya I know it's not the Suter) with "out" on the correct side, so re-assembly is easy. Except.
The Diaphragm has "tuo" on the wrong side.

I wasn't too stumped, (and it only really fits one way anyway. But I thought I'd mention it.
So on to easy re-assembly!
Pa-TING! Crap...

Is it time for that beer yet? Grrrr... Seriously just running the long bolt down and blam! There the spring, now wheres the stepped washer? It sure ain't a hardware store item...
5 mins, 10 mins, 15 mins, oh there it is..

This town does not have an auto parts store. Seriously. Pathetic.
What they do have is an awesome True Value that's been here forever and has a totally legit fastener room.
M6/1.0-45mm in case you were wondering.

I'm not taking a chance with the rest of the OEM hardware.
A little punch

I'm not much for kissing guys, but if it was a man that invented Left-hand drill bits, come on over and get ready for a smooch. You too "red cup" guy....

A little chasey chase chase. I didn't use a tap, I'm not trying to make new threads, just see if theres a burr or something.

Done! Just in time to take my hot alien out to dinner. You DON'T want to make her angry!

Did you overtorque it? I would order the replacement screw on McMaster with the maximal yield strength I can find there.

I really don't think so? I was just loosely turning it down. I hadn't even got out the inch/lb wrench yet!
It broke super, super easy, I think I avoided an expensive problem. If the head would have snapped inside, I doubt I'd have known until it and the spring, and the heavy stepped washer rattled around or even punctured the coverLots of spinny stuff in there.
The new ones are grade 8.8, just like the OEM, except zinc coated as you can see. I'd hesitate to just get a harder (10.9) bolt because they are more brittle. The amount of vibration and fatigue down there must be massive so I'll be confident in the engineers solution and not try to out think those very smart people.
