Reply To: Stubborn Flywheel, Gale 40 hp

With the puller as tight as possible, get a heavy pry under two sides of the flywheel (to avoid bending it). Then give the center bolt a whack with no bigger than a 16 oz hammer. You probably need an extra hand to help pry and whack at the same time. You are driving the shaft out of the flywheel. If the shaft is not lifted (by the pry), it has nowhere to go, no matter how big a hammer you are pounding it with.
I don’t approve the sledge hammer route. Others will disagree.
