The impeller is just screwed on the shaft. COUNTERCLOCKWISE to remove. Some have a screw in the center attaching it to shaft. This is removed by by turning CLOCKWISE.(reverse threads) Remove back cover and secure shaft with a wrench. There are flats on the shaft to hold it. You might need a large pipe wrench to loosen impeller. Wrap with rag so you don't damage impeller.

Can my shaft spin and not my impellor. how can i check


the impeller is usually screw onto the shaft or the shaft has a D (flatspot on one side to lock impeller) so no, the shaft cannot spin without the impeller moving unless the shaft is snapped or impeller is totally stripped (ive never seen either)
if the pump is running but not pushing water, take the wet end off and make sure there is no debris (leaves, worms etc) caught in the impeller fins. you will be amazed at how much that will reduce the performance of a pump

Marathon wiring


Are you sure? Single phase pool motors are not reversible (unless something weird happened that I can't explain). Three phase motors are reversible, but very rare in residential wiring.

Looking directly at the end of the motor shaft (where the impeller goes) it should spin counter- clockwise. Both of the power wires can be attached to either terminal; there is no "polarity".

Reverse direction of electric motor


If your motor runs backwards, you wired the motor backwards. Change your wires around and it will run the correct way.

Where I can buy the A.O Smith 3/4 HP pool pump impeller?


You'll need information from the pump that the AOSmith electric motor is attached to in order to get an impeller or any other pump parts. If there is no nameplate for the pump are there numbers on the impeller you need?

Remove the back of the motor ... you will find there are flats on the shaft. Put your 7/16 or 1/2 open end wrench there and with your other hand, spin off the broken impeller.

How do you detach the impeller from the motor shaft


Lock the end of the shaft opposire the impeller and turn the impeller counter-clockwise as you look at the impeller. Some of them require a little 'convincing' in order to get them to spin.
