    So I seem to have a problem, I bought a 1995 360 from the original owners and tried to pull the mag, using a proper puller, it's the 2 piece type that uses an inner bolt
    so got it on there and put enough torque to start twisting the inner bolt, nothing
    used a MAP torch on the flywheel, nothing :mad:
    so anyone have a special trick for a mag that has not been off for about 22 years :confused:

    I was working on an old 390 engine, and had to have somebody build me a puller for it. Then I couldn't get the thing to budge. I tried an impact, a hammer, heat....phooey! Finally, I walked away from the engine for a second, and while my back was turned, the puller and flywheel just went pop and came off!:eek:

    I've seen the flywheel actually spot weld itself to the crankshaft, probably because of harmonics or maybe the nut wasn't completely tight. I broke a snap-on puller and the force mushroomed the end of the crank. Not very often but sometimes you have to destroy the crank to get the engine apart, eventually you run out of options.

    Remove the puller, put cover back on and list it on Craigslist as a going concern. ....

    But seriously remove puller put some pb down the gap, re install the puller put tension on and heat leave to cool apply more pressure apply heat and give a tap on the pullers bolt whilest it's warm.
    It's In the hands of the dirt gods now.
    Just keep repeating the process it should come. In the end.

    If it's between letting her go and never knowing of the pain she came too and destroying her by my own fair hand I would choose selling her, too many times I have inflicted more punishment thanks is needed.

    pssshh, over a flywheel?? itll come off. if anything it just needs some heat.

    ive seen some old timers keep a toilet bowl wax ring around the shop...use it with the heat to melt and penetrate. ive seen it work on some stubborn stuff
    of course, with the puller installed real tight and a bit of heat applied you can wack the end of the puller a bit...straight in..

    so good news, put on the puller, used a heat gun and walked away, it came free over time
    thanks for all the great responses
