    Howdy all. I'm replacing a bad well pump motor and have run into a little
    snag in disassembling the old one. The spindle of the old one is attached to
    the "flywheel" (sorry... not sure about exact terminology here!) and I am
    stumped on how to proceed in removing it. It looks like it is basically
    screwed on, but the spindle rotates freely and I have no means of locking it
    down. I think there's some sort of thin lock-nut at the tip of the spindle,
    but I see no way of getting that off. Sorry to be vague here... I can
    provide photos if need be to help further clarify what I'm talking about.

    This is turtle.

    Now I can't see it from here but here goes at a guess.

    The Treads your looking at is the pull adjustment to the v shape pulley belt
    slot. To Take it a loose there wll be 1 or 2 allen screws holding the pulley
    head on the shaft. Look for allen screw heads to take it loose from the shaft.

    TURTLE.

    Thanks for the tip. Unfortunately there are no screws (allen or otherwise)
    left in the way. I think I'll just find a shop I can take it to tomorrow
    since I wouldn't get an adequate picture of this to give anyone a better
    look. Thanks for the suggestion though.

    I rebuilt a spa pump recently. I believe I had to partially remove the
    starter switch on the other end of the motor to find a flat spot on the
    shaft for a wrench to hold the shaft.

    It is threaded on in the same direction that the motor runs. If you
    turn the impeller in the normal direction it will unscrew. Take the
    bell cap off the opposite end and there will be a screwdriver slot or
    flats a wrench can grab to hold the shaft. Wear leather palm gloves
    to grab the impeller.
