Product details

The Century B129 is a 1.5 HP threaded shaft pool pump motor, single phase, wired for 115V or 230V on a 56J frame. Our source also catalogs the same motor under the A.O. Smith and Magnetek names.

Ratings

Label horsepower is 1.5 with a 1.3 service factor, which works out to an effective 1.95 horsepower. Amp draw is 18.4 at 115V and 9.2 at 230V. Physically it is 11" long and 6-1/2" in diameter, with a 2-1/2" shaft and four mounting holes.

What it goes on

This is the threaded shaft version, which is the style the Hayward® Super Pump family uses. It is listed for the SP1600, SP1600X, SP2600 and SP2600X. Before ordering, confirm your existing motor has a threaded shaft rather than a keyed one, and check the frame is 56J.

Cross references

The motor appears under several numbers, including ST1152, 35B1189 and 16430400. Our source writes the catalog number both as 7-164304-24 and as 8-164304-24, so read the number off the plate on the motor you are replacing and match on that.

Questions and answers

What people ask about this product, answered by our pool techs.

Which pumps does this motor fit?
It is listed for the Hayward® Super Pump SP1600, SP1600X, SP2600 and SP2600X. It is a threaded shaft 56J frame motor, so the wet end has to be the threaded shaft style.
Is it 115V or 230V?
Both. It is a dual voltage single phase motor, drawing 18.4 amps at 115V and 9.2 amps at 230V. Wire it for the supply you have.
What does the 1.3 service factor mean?
It means the motor is built with headroom above its 1.5 HP label rating, giving an effective 1.95 horsepower. Two motors with the same label horsepower can move different amounts of water because of it.
What other part numbers is this motor sold under?
Our source cross references it to ST1152, 35B1189 and 16430400, and gives the catalog number two ways, 7-164304-24 and 8-164304-24. Match the number on your old motor plate where you can.
