Will a 3/4" clutch fit?

[qtband]

Ok, now that we have been told it is a 20mm shaft and NOT a 3/4" crank, how about the other questions raised -- what is the keyway size? what is the drilled and tapped hole at the end of the crank and most important is it a 12 volt electric start or is it 110 with a long extension cord? We are waiting with baited breath.

The keyway fits my 3/4" clutch. I didn't have to mess with it.

My 3/16" keyway fit fine. 12volt

Be aware.... If you use a torque converter, the crankshaft length will need to be addressed. I decided to use a TC instead of the centrifugal clutch so I had to extend the shaft. Easy, if you've done it before.

This, I'd like to see.

Nothing. Not looking to get banned.

I was gonna suggest rolling it like play dough.

I wasn't joking ...but those other guys are quite incorrigible. Show us how you extended your crankshaft, por favor.

Im finished with the kart and it's out the door, but I can tell you how I did it.
I took a piece of 3/4" jackshaft and cut it down to 1.5". Used a lathe to put a center hole through it. Chamfered the crank and the extension . Used a bolt to hold it on along with a long key to line that up. Welded it with the mig, careful to keep heat off the seal. Finally, cleaned up the weld. It was true as can be!
