I striped it! I lightened the flywheel, and for some dumb reason I decided to put it on with an impact wrench. I threaded it all the way up to the washer, and then used the impact. I was under the impression that this was under alot of torque!!? The flywheel came off with so much force, so I thought that the nut would have to push it on with alot of torque. The nut just kept turning, and I have a cheap impact wrench... After I took the nut back off, the flywheel pulled off by hand. I used antiseeze on the shaft and the treads.

What is the torque spec for the nut?

 

on my 2000 scrambler it is 58-72 foot pounds
