Title: Torque specs?
Post by: cnrcpla on April 15, 2012, 09:15:45 PM
I just cleaned all my clutch plates and let them soak. I was looking under the clutch basket and found a C clip resting right in my gear box. I got it, and looked it up online, and it appears as though it came from this gear (the one right under the kick starter shaft): http://www.southbayriders.com/forums/showthread.php?t=110584 This gear is behind the clutch basket, and I need to take the basket off. So, I NEED to know, is it 53ft lbs? This is what the manual I have says, but it is in three languages and has been proven to be unreliable... So does 53 foot pounds sound good for this bolt?

I'm going with the 53, but how in the world so I keep the inner hub from spinning while I am trying to torque it down?  :-[ Any way of keeping it still enough for me to torque it down  ;D

You need to buy a clutch holding tool.
Or you can modify a pair of vise grips to do the same.

The vise grips is a good idea... I wont bend it or warp it though, would I? I have some tools to buy...  :-X

The clutch holding tool is a modified vise grip.
What I was meaning is if you have an old pair laying around you can weld some plate to it to match.
Borrow someones clutch tool and copy it.

I see how one works... Unfortunately I don't have access to the shop (or a welder) for a week  :(  I think I can screw around with a strap wrench and maybe make it work...

Just for future reference; if the engine is still in the bike you can knock it into it's top gear, hold the brake, and you'll be able to remove or torque the clutch hub nut easily.

I actually took a whole different approach. I put all the plates back in (after a couple of days soaked in oil) pressed them together and tightened the nut with a power drill. Then I took the plates out and used a strap wrench to torque the nut down to specs. Thanks for the ideas guys  ;D
