A.O. Smith Threaded Shaft Motor, One Speed
These quality A.O. Smith Threaded Shaft Motors are found on many brands of pool pump. Some of these pool pump brands are Hayward, Jacuzzi, and others.
These motors directly replace the "original" motor that came with your pool pump. No pump manufacturer manufactures their own motors. We sell A.O. Smith motors because we have found them to be long lasting and reliable. A.O. Smith manufactured motors are the only brand of replacement motor we use in our local repair work.
In our chart below, we match "uprated" motors to their "full rated" equivalents. An uprated motor and a full rated motor are often the same motor with two different labels. We have attempted to simplify this with the chart below.
