Need a little advise on getting the primary off. I put on the puller and used the impact and hit with a 2 pound mall. Would not break free. Impact would not advance the puller any further. I do not have a holder but could hold with impact. I am afraid to hit the puller to hard and damage the crank. Does any one have any suggestions? How hard was yours to get off. I am going up this weekend and would like to put on my clutch kit.
