Question about AO Smith Pool Pump Motor 1HP Square Flange Swimming Pool Pump Energy Efficient motor
I have removed bolts, impeller etc. I am replacing the existing motor with same model but cannot get the seal plate off the old one. HELP!
It sounds like the seal has a death grip on the motor shaft. Pick up the seal plate so the motor is hanging beneath it. (watch your toes) Holding it about waist high let it drop and then snatch it back up again. Kinda like getting a pillow in its case. The motor should drop out.

Testimonial: "it is a death grip, 'cause it refuses to come off. I bought another seal plate, the original manufacturer does not make them anymore, but after replacing literally everything it still is leaking. I replaced motor, shaft seal. I had to make the drill out part of the new shaft plate so maybe that is the new leaky prob. I would just like to use the original one, but cannot get it off the flange."

One or more of a couple issues is at play here. First would be the seal replacement. Even if you used the correct seal if you touched the surfaces or failed to install it properly it can and will leak. Second, inspect the housing around the seal fit and the stem of the impeller for cracks. A hairline crack is enough when placed under pump operating pressure to allow a leak. Somewhere in there is your solution.

Testimonial: "John: Hi! Thanks...maybe it could be the surface was touched....and maybe the spare motor had a worn seal. The fact that both were leaking in exactly the same place is a mystery. I took the motor I worked on to the pool vendor for an exam. Thanks for your feedback...it was helpful. ndmc"
If you have removed the impeller this is what you need.
Part number for your shaft seal is : 37400-0028s
Here is a link to the manual on how to install / remove this seal on this pump:
Refer to page 9.
This seal can be purchased anywhere on the internet. Just do a google search with only the part number. Many suppliers will come up. If you have trouble, I have a few and can make an E-bay sale for one.

SOURCE: Hi, I have a QC 1072
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.

voltage set right? motors come set from factory 240 v .. or you might have moved the start switch, it's at 6 0clock on the motor make sure its centered (back of the motor) shaped like a v.. looks like this.click on this
also might be a bad start or run capacitor..or a dud motor
hope this helps

Yes. The one that doesn't have the capacitor on top has it inside.
