- Help With Small Motor - 3 Updates
| Klay Anderson <mailserver.cctv@gmail.com>: Dec 15 03:05PM -0800 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. |

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. Peter Wieck Melrose Park, PA |
