SOURCE: just replaced a Hayward 2hp pool motor with a OA

Hello
No there is no switch in the motor.Correct voltage is done by hooking up incoming power to a combination of internal wires or contacts.

There should be a wiring diagram on the cover where the hookup is.Or on the outside case of the motor.
The high and low speed doesnt make sence to me.Check the rpm of the motor it should be one rpm continueous.
Unless this is a Hvac motor and not a pool pump motor.Possible you may have been sold the wrong motor.
Usually a pool pump is 115 volts 1 speed and 1 rpm continuos duty.Unless you specify 230 volts.

How do I break down pool motor aol 1-1/2 hp


It depends which pump you have, on hayward super II you shut off the breaker, remove the rear motor cover, disconnect the electrical wires, then remove the 4 (9/16")bolts holding the motor to the "wet end" which is where the basket is. Now, pop off the diffuser, sometimes it stays in the wet end when you remove the motor. At the rear of the motor, use a 12mm wrench to hold the shaft, then unscrew the impeller (counter-clockwise) after removing the impeller, theres another plastic plate that lifts off, remove the plate, now there are 4 (9/16")bolts to remove in order to separate the motor from the seal plate. You have now broken down the pump. If you replace the motor, make sure to get a new seal as well (ps201)

I have a hayward pump model SP2610X15 that will only hum when turned on. I replaced the capacitor, it did not help. What else could be the problem?


DIRTY START switch or the motor is locked up, breaker off ! remove motor from tank body and see if the motor will turn over if it does could be the switch or the motor is shorted witch there is no fix but a new or rebuilt motor. search your area for your local pool pump motor repair guy with free testing..

All I want to do is find a replacement switch for my 1.5 hp pump motor. It is a hayward power-flo matrix, sp1515-z-1-esc


Please post the model and serial number from the motor. The number you have is the part number Hayward assigned to the AOSmith motor on your pump. I'll need AOSmith's info to get you pricing on the correct switch. Do you need the stationary only or the stationary and govenor?

I NEED TO LOCATE AND REPLACE A O. SMITH IMPELLER ON A 155 HP POOL MOTOR


A.O. Smith is just the motor. If your pump is a Hayward any pool store can help. Take your old one in and they can match it. Be sure to get a new seal while your at it, It should be a #201 seal. If you pull the whole motor and pump face the pool shop can probally do the work for you and gennerally don't charge except for the parts. Good luck
