    use your favorite penetrant in the cylinders.
    drain the cooling system.
    fill coolant system with boiling water.
    rock the tractor back and forth till loose.
    repeat if needed.
    this has worked for me, use a propane cooker for deep frying turkeys!
    It heats up about 3 gallons of water.
    TEAMWORK is essential, it allows you to blame someone else!

    fill the cylinder up with transfluid or marvel and then put an air chuck ( the type for holding valves for seal changes) and give it a shot of air ( loosen up the adjustment on the rockers to close the valves . the air will force the oil into the rings and help loosen it up and might posibly pop the motor over .

    Thanks for the tips guys
    It has a mix of diesel and crankcase oil in the cylinders
    it's been soaking for a while and I'm going to let it sit for a month or so

    our local welder has his eye on it
    we will see what kind of trade he comes up with

    I like the air pressure idea
    thanx

    Water pressure is safer. When something moves a bit under air pressure, it'll go flying . Water pressure moves stuff slowly, no projectiles.

    Just to add my two-pennyworth, Tow'd,
    the guys who pressure-form sheet-metal for small-scale production strongly advise you use liquid pressure, normally water, for the reasons R Pope has stated. Water does not compress under pressure, so movement is incremental, whereas air does, and can store massive amounts of energy, then when something gives - it can release it in one go; think of an air-rifle.
    These guys use liquid to hand-form 'bike fuel tanks, two-stroke exhausts, etc.; it's more controllable.
    ps, I've had success in the past with diesel and kerosene mix. You sure ain't spoiled for choice

    Make a grease zerk adapter for your spark plug/injector hole and grab your handy grease gun, 3000psi is easy with a hand grease gun, most air powered ones will hit 5000psi, this has worked for me all three times I've done it.

    wow thanks for all the methods to free up the old tractor motor
    lets see we have
    WD-40 and penetrating oils
    block of wood and a BFH
    brake fluid
    Marvel Mystery oil
    ATF
    Iodine
    water pressure with a pressure washer
    Boiling water
    air pressure and
    grease

    lots of methods to free that motor
    maybe we will try all of them at once
    something will give

    you guys are great
    thanks
    hank
