Re: key way

Sam, Those are standard woodruff keys. Anyone that will fit will work. The flywheel nut must be tightened properly or they will shear everytime. I believe teh correct torque is 95 ft lbs, but you should verify

Re: key way

They are a special size and the flywheel and crank tapers must be clean and dry and the nut torqued to 100-105 ft/lbs, using a torque wrench.

Failing to do that will shear the key and often destroy the tapers and keyways. When that happens, it is all over.
