I always use an impact wrench on the puller bolt. When doing this use a 3/8" wrench and on low or medium, never on high. The light blows will pop it right off without much effort. You won't need to hold the clutch when doing this.
When installing, clean up the shaft and the bore with Emory paper or scotch bright and use a good anti-seize compound. Don't worry about the clutch spinning in the bore with anti-seize, the taper won't allow the clutch to spin. So next time it won't be such a pain in the a$$ to pull.
