    Yeah…. I am not a supporter of using a hammer on the flywheel nut & crankshaft to pop the flywheel loose.
    I am aware that there are some service manuals that mention this method, but the risk of damaging the threads
    on both the nut & crankshaft is high in my opinion. Even if it is sucessful once or twice it does stress & fatigue the threads.
    Working on motors regularly I feel having the right tool is key. Flywheel pullers come in all shapes and sizes or you
    could always make a puller to fill your needs if one is not avalible as I have needed to for my Rowboat motors.
    It’s unfortunate purchasing a motor to restore and finding you have to address a damaged crankshaft due to
    a hammer mechanic.

    Just another view point.
