I am having problems aligning my 401 balancer keyway with the crankshaft key. I have a rebuilt OEM vodka nicer from damperdoctor. The key does not extend to the end of the crankshaft and due to the tight fit of the damper on the crank shaft it is very difficult to try and align the damper keyway to the crank key. I thought I had it aligned but I did not and dig into the side of the damper keyway ruining my hub. I am sending my damper out for repair.

Idealy, I would like for the balancer to fit loosely on the end of the crank so I can rotate the balancer relative to the crank to align the keyway and key. Is there some trick to this? I have read about people heating the damper to 200F before sliding it on the crank. Would heating allow me to push the damper by hand onto the crank far enough to align and engage the key in the keyway before requiring force to completely install the damper?
