Quick Overview

The AO Smith BN36 2-Speed Pool Pump Motor is a thru-bolt style motor with a 48Y Frame with a high speed of 3/4 HP and a low speed of 1/8 HP. The BN36 Motor has a 1/2 inch diameter shaft with 3/8 inch threads on the end. Thru-Bolt style motors are most commonly used on Hayward Power-Flo pumps (all power-flo styles), Pentair Dynamo and OptiFlo pumps, AquaFlo Flo-Master, FMHP, FMCP, Tub-Master and several other pool and hot tub pumps.


It is important to know that pool pump motors are not manufactured by the pump manufacturer, the motor will usually be manufactured by AO Smith, Magnetek or Centurion. Your pump's motor should have a label or faceplate on it which includes the information you need to replace your pump motor. The most important categories to note will be the horsepower (hp), motor frame (fr), voltage and service factor (sf). Some labels will provide you with a model number and it will usually be listed as CR or CAT.

When replacing your pool pump motor you should always replace the shaft seal as well. The shaft seal is a 2 part piece made of rubber, metal and ceramic and keeps water from entering the pump motor. It is located near the impeller at the end of the motor shaft. Shaft seals vary between pumps so be sure to order the appropriate shaft seal for your pump.
