The last few times I have tried to pull my primary clutch off, I have been having a real hard time. After pounding on the end of the puller with a hammer and using a breaker bar it will usually come off after a while, except for this last time. I was using the breaker bar and the end of the puller snapped off! After hours of drilling, I finally got it with an easy out. But I do not want to go through that again. It is almost like the fixed sheave is rusting on to the crank shaft. Everytime I take it off I clean them really well. Has anybody had this problem? Is there any solutions for this. I wonder if I placing a little never sieze on the crank shaft will help (even though the shop manual say not to)? Anyone have any opinions??
