Re: Out of Tricks, very stuck flywheel
I just put another two hours into it. This time I built a wood stand that holds the engine up, by the bottom of the fw. So the motor is 1" off the ground, the fw is being supported, and the weight of the block is pulling down on the flywheel. I heated the entire fw to about 120 degrees, with a heat gun. Took my impact gun tightened the puller till it stopped turning, pryed up on the fw, then whacked it with the hammer. I kept repeating the process, including grinding the center bolt back into shape after I hit it for a while. After an hour, I just cranked on the puller with the impact gun, and broke another bolt. Can I make the three holes larger and re thread them for larger bolts? Any possible problems?
