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.

Help! Just opened my pool and the pump/motor (which is only 2 years old) is very noisy. Sounds like it could be the bearings. Do call someone to the house, disconnect and take to a repair shop, ord

Disassemble the pump to the point where you can see the whole impeller. Then turn the power back on to verify that it is the bearings, and not trapped debris causing the noise. If it is the bearings the short answer is to replace the motor.

Bearing failure is usually related to a leak at the pump seal. This results from either a faulty seal installation, or the pump running excessively hot (from running w/o water).

When replacing the motor carefully examine the seal plate (where the seal is set) front and back for any cracks or deformity. If the new seal doesn't set exactly, it will leak.

If AO Smith 1.5 HP pool pump mootor is turning the wrong direction could that be the reason for not priming. If so how do you change the direction of spin?

these motor have been known to do this, you could have the capacitor checked or replaced, it might be a bad motor.. i would look to see that the shaft seal is good (new) and no suction leaks and that the pump has been primed.. if not its time 4 a new shaft seal.. it only takes a short time to burn up the shaft seal
