    Maybe this has already been said, but saying it again.

    1. Use the shoulder bolts or thread Grade-8 bolts in 7/16"
    2. Tighten the puller as much as you dare without snapping the bolts.
    3. If it hasn’t popped off yet, RAISE the flywheel with a pry such as a large screwdriver (I didn’t say a 4′ crowbar)
    4. Strike the puller center bolt with a hammer. In necessary repeat 2, 3, and 4.

    Bashing the snot out of it with a sledgehammer is not the way to strike it. It is the sharp whack that does it, not the mortal bash. And if you don’t hold the flywheel up (#3) the crankshaft has nowhere to go, so your hammer strike does no good.
