    Guys -
    My 79 390 Auto project continues. I'm trying to remove the swing arm bolt and am having a heck of a time even budging it. This is what I've done:
    • removed both end nuts
    • applied penetrating oil
    • aggressive use of rubber mallet
    • flame heated engine case with LPG torch
    • hammer on a metal drift
    With all this, not a mm movement in either direction. The bolt seems to be attached to the motor since moving the swingarm doesn't move the bolt ends, but after removing the front engine mounts and lifting the engine the swingarm bolt ends twists with lifting the motor.

    Not sure it there is a trick out there, but if so I'd love to hear it!

    Thanks,
    Scott

    Make sure the bolt isn't grooved... I have seen several swingarm bolts with about a 2x2 mm grove in them. One groove on each side right where it goes through the frame mount/hole. If that is caught in the frame you could beat on it all day and it would never move.

    Get a good light to shine in the general area nd use a pry bar to move the motor around to see if it has a groove that it is catching on.
