• Help With Small Motor

    From Klay Anderson@21:1/5 to All on Thu Dec 15 15:05:43 2022
    The album <https://imgur.com/a/6wgKqmj> shows a small motor and impeller from a water pump. I cannot figure out how to get the impeller off as the other end of the shaft is enclosed. I am trying to replace the bearing. Google is not helpful. Thank you.

    It looks like it is designed for you to hold the impeller and turn the
    shaft with a flat blade screwdriver. The blade slot is a little chewed
    up, so make sure you have a really well fitting screwdriver to match the
    slot.

    I would recommend starting by trying to get any tiny motion turning
    either way, then work it carefully a tiny bit at a time, turning back
    and forth, going a little looser, lightly tighter over and over again to
    work the threads free without mutilating the screwdriver slot.

    All good as is what follows. However, I would go with standing the motor rotor-up and putting some Kroil, Penetrating Oil or some similar material onto the shaft end and let it sit for 24 hours before attempting to remove the impeller. Further, if you
    can clamp the pump in some way as to render it rigid, it would make the process easier. As these things go, typically, impeller removal is not overly difficult if the shaft has not corroded such that it has swollen into the impeller. And when you put it
    back together, a we touch of anti-seize would not go amiss.

    ** Looks like a special driver is needed, one with a centre pin and two flats.
    Also watch out for the thread to be reverse to normal.

    The threads will be set to tighten the impeller in the normal spin direction. So, to remove it, turn it in the running direction.
