B858, B2858 Pool Pump Motor 56Y Frame 1.5 HP Square Flange 115/230V - Full Rate

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.

IMPORTANT NOTE: Pumps and replacement motors that are single speed and one (1) HP or greater cannot be sold, offered for sale, or installed in a residential pool for filtration use in California, Title 20 CCR sections 1601-1609. We recommend either a dual speed or variable speed pump for California residents.
