Note: AO Smith purchased Magnetek Electric Motors. This means these motors will become AO Smith Motors, possibly with dual part numbers. You may see an equivalent AO Smith motor replace the Magnetek Motor. Either way these motors are exact replacements. Century Electric Motors are also part of AO Smith Electric.

48 Frame pool pump motor
These motors are unique to Doughboy and Lomart above ground pumps.
These electric motors are probably the most common swimming pool motor. The pump is attached to the round “C-face” of the motor via the 4
threaded bolt holes. 56J frame motors have a 5/8" diameter threaded shaft.
frame pool motors have a “keyed” shaft, which are very common to well
pump motors. 56J motors are common to most Hayward in-ground pool pumps (Super
Pump, MaxFlo and Super Pump II.)
Phase and Three Phase motors.
56J motors are common to most Hayward in-ground pool pumps (Super Pump, MaxFlo and Super Pump II.)
Single Phase and Three Phase motors.
48Y (56Y) Frame Square Flange pool motor Single Phase and Three Phase
These swimming pool motors have a “square” face that the pump attaches to, it also has 4 non-threaded bolt holes to attach the pump. The motor has a threaded shaft. Square Flange pump motors are common to most Sta-Rite, PacFab, Purex/Trition and WhisperFlo, Challenger inground pool pumps. Single phase and three phase motors.
These electric motors are just like the 56J motor, except they have a 5/8" diameter keyed shaft. The impeller is mounted with set screws.
TIP: To remove the threaded impeller from the motor. The impeller is "screwed" onto the motor shaft, with standard threads (righty tighty, lefty loosey). Remove the end cover (wire end) of the motor (some motors have a "bearing cover". Some motors have a slot on the end of the shaft, some have flats (7/16" flat wrench). Hold that end of the shaft with either a screwdriver or flat wrench, then unscrew the impeller. Be careful not to break the impeller (cost $15 to $55).
If your not sure which swimming pool motor you need for your pool pump call us or e-mail us. We will be glad to assist you in your selection.
All single-phase pool motors are CCW (counter clockwise) Facing the Shaft - Non-Reversible.
All dual voltage (115/230) electric motors are shipped from the factory wired for 230 volts.
