    Never pulled one off the hub, but I have had to go up to a 3/8 Heli Coil insert once, to get one off. That baby was on there! This was a 57 Big twin, that was purely original. I ended up putting an electric start flywheel on anyway.
    You DO NOT want to use an outside type puller that grabs the rim of the flywheel. It will bend or break the flywheel, right around the hub.
