Clutch hub.... Success!

I posted last week about a stubborn clutch nut and got some feedback from the Yamaha facebook group. I put the bike in 4th gear and used my socket with extension bar and still couldn't get the nut to move. What I really needed was an impact wrench but my compressor was 50 miles away in my other home.

There are electric impact wrenches which have become popular recently , I've seen the ads in my fb page, and I was toying with the idea of getting one. I got off work a bit early on Friday and on the way back I stopped by a hardware shop near my house and they had a promotion for power tools. The promotion was for an unheard of brand called DCA which is from .. China! Well for the limited used that it will see I think it should be fine. At around USD75 its not too expensive.

I got home and hooked up the e-wrench, on the second press of the trigger the nut unscrewed right off! Next was the crankshaft gear nut.. one more press of the trigger and it came off (left-handed nut). Should have gotten one earlier, would have made life easier when doing the brakes on the MB!


Here's a pic of the right side of the engine with both the clutch hub and crankshaft nuts removed.


I tried rocking the clutch shaft, not much where present. That sound is basically the front sprocket moving the drive chain and taking up slack.

And this is the tool I bought. Not bad at USD75.

Next is to get the stuff on the left-hand side of the engine off. Flywheel, contact-point/coil plate, gearshift stuff, front sprocket (another opportunity to use my new tool!) before I drop the engine to get deeper.

Flush with the successful removal of the clutch hub, I decided to move on and open the crankcase and see if I could figure out what that aw...
