Hey TFP, I just moved into a house with a pool and having issues with my pool pump (PFII-P1-3/4). When I turn the pump on, the motor (USQ1072) hums for a few seconds and shuts off. It's been doing this on & off since moving in a month ago, and finally it stopped working completely. I took apart the Wet End to check for debris and everything looks good. With the motor detached from the Wet End I tried turning it and it wont budge. I ordered a new motor from Amazon, everything on the specs match except for the SF original 1.27, new one says 1.30. From what I understand the Service Factor shouldn't make a big difference? I also ordered O-ring rebuild kit with the Shaft seal. Unfortunately I didn't check how the Shaft seal was oriented and don't want to make a mistake reassembling it. Does anyone know the correcting seating? Also any advice, tips? This is my first pool & very excited to get it going, below links to the parts I ordered & pictures of current parts. Thank you for your help!
