Century USQ1102 1 HP, 3450 RPM, 1.25 Service Factor, 48Y Frame, Capacitor Start/Capacitor Run, ODP Enclosure, Square Flange Pool Motor

The motor seems to work fine. It was difficult to install and did not come with gaskets. Only time will tell how dependable it is.

It was a great price for a replacement motor. It is exactly as described and easy to install

The pump on my pool failed and so I ordered this replacement before I had closely inspected the whole of the pump. The motor is perfect but when I came to install it I found out that I had to replace not only the motor, but also the seals. Then I found the mounting seal plate was cracked so that needed to be replaced too. Then when I came to fit the seal into the impeller that needed to be replaced as well. In short everything except the diffuser needed to be replaced. I would have done better to buy a "power end" unit which includes all of the parts needed and ready assembled. It would have saved a lot of my time and not cost any more. It would have also been quicker than waiting for all of the parts to arrive only to have to order something else.Having said that there are plenty of good videos on YouTube showing how to replace the motor and other parts so there is no need to spend double on getting a pool company to do it.If you don't already have one, I suggest also buying a motor cover (I didn't previously have one) to reduce the corrosion if your pool pump is outdoors.

Works good my third pool pump motor in twenty years

My original motor had a tapped hole at the end of the drive shaft (the shaft you see in the picture) where an "impeller retaining screw" screws on to secure the impeller to the shaft. This replacement motor did not. I did my best to match pumps specs but I may have missed something. So if you are using this motor in conjunction with a pool pump, Pentair specially, take a look at the impeller to see if you need a drive shaft with a threaded hole at the end. Although I must say the pump/motor is working flawlessly without the screw. The threads on the impeller alone seems to be enough to secure it to the shaft and the retaining screw may have been proven unnecessary. But just thought I'd put it out there.

Seems like a good motot, but was not actually an AO Smith. Everything was an exact fit except bolts which hold the motor to the pump housing. Those had to be replaced with new ones which are a quarter inch longer. Runs quietly and functions just as the old one did, but does seem to run a bit hotter than the one it replaced. Anticipate somewhat shorter service life based on the extra heat. Old one ran daily for 8 years. Minor issue: The motor electrical terminal connections are very close to the cable entry hole, and it took significant effort to get them properly connected.

Motor has only been in service a few days, but it mounted nicely on my Challenger pool pump. However, the shaft on this motor is not threaded to accept the stainless locking bolt used on the factory motor. However, this shouldn't matter, as the impeller - as in all pumps - threads in reverse, so the impeller is tightened as the motor operates. Also, a very minor issue, the motor housing is approx 3/4" smaller in diameter than the factory original. It is best practice to have the motor mounted level, so I compensated the difference with some "field fabricated" high density foam, which is strong enough to resist collapse from the motor's weight. I also like that this came wired at 230V from the factory, didn't have to mess with any wiring changes, easy-peesy. I bought the 4-year warranty, BTW, something I normally never do.

A pool motor should last 8-10 years under typical conditions. This one lasted only three pool seasons due to a now documented fan defect. The cheap plastic cooling fan detaches from works and allows the motor to become super hot. After heating up to a dangerous level the motor will turn itself off until it cools down. It then it restarts the cycle all over again. In my case the motor got so hot so many times that the copper winding started to come apart (see photos). Hate to sound like a hater (I'm not) but when these motors were made in the US they lasted many years longer. So this is a typical example of the false economics of outsourcing manufacturing to China. This part is maybe 10-20% cheaper than it would be if made in the US or Europe, but it only last a third as long as it should. So I have to buy this "cheaper" product 2-3 times as often AND expend time and effort reinstalling it. Plus there is now the added environmental cost of putting the old stuff in a landfill (or recycling center) and manufacturing the product three times. I'm going to look for a different motor this time.
