Could this be a California Compliant replacement for a USQ1202?

Will this work on a hayward SP2310X152

A  Answered on 6/25/2021 by InyoPools Product Specialist Craig C.

Hello Eric.  The Century Motors 1.5 HP Dual Speed motor model SQS1152R has a Total Horsepower (THP) of 2.21.  The Hayward MaxFlo XL pump model SP2310X152 was originally manufactured with a 1.65THP motor.  Technically the SQS1152R is a compatible replacement.  The Century Motors Dual Speed motor model SQS1102R has a THP of 1.65.  The SQS1102R is less expensive than the SQS1152R.  Century 1.0 HP Square Flange 48Y Dual Speed Full Rate Motor - SQS1102R  It is recommended that the motor shaft seal be replaced at the same time.  Please see attached.  Pump Shaft Seal 5/8" - - SPX2700SA PSR-200

Can I replace a 2HP Sta-rite dyna-glas square flange 48Y single speed with this 1.5HP CA compliant model

A  Answered on 5/18/2021 by InyoPools Product Specialist Patrick P.

Could you send us a few photos of your pump and motor? Please take a close up shot of the motor label as well as a wide shot of the complete pump to include the pipes going in and out of the pump. To supply photos simply click the reply link below and upload your photos. Once we get those photos we can make the proper recommendation.

ordered SQS1152R & GO kit 54 your recommendation, to replace my old P2R5F-126L motor (SQ1152) Problem is shaft seal does not seem to compress enough to allow seal plate to sit flush with motor mounting surface where 4 bolts attach. there is 1/4 to 3/8 inch gap between the two surfaces when fully compressed. Are there miss- matched parts or some other problem?


A  Answered on 1/29/2021 by InyoPools Product Specialist Hector F.

Hello Paul, unfortunately, there are no orders with us attached to your account for a motor and seal kit besides one that was cancelled due to not being California 20 compliant however that order had a GOKIT6 on it for a Sta-Rite Dura Glass/ Max E Glas pump. The shaft seal in the GOKIT54 will be compatible however if you have a copper cone insert in the seal plate that will need to be removed.

Installed this motor and it appears the impeller needs a counter clockwise motor rotation. Can the motor direction be changed.


A  Answered on 11/13/2020 by InyoPools Product Specialist Hector F.

Hi Eugene, these pool motors are designed to only spin in one direction and cannot be changed.

Will this replace a Sta-rite Max E Pro 2 - 1/4 hp pool pump motor? Pump model number P6RA6YG-207L

A  Answered on 12/17/2020 by InyoPools Product Specialist Hector F.

Hi Alan, yes, this is the correct dual speed replacement motor for the motor on the P6RA6YG-207L . You will also need a Sta-Rite Max-E-Pro tune-up kit when you replace your motor. We put together this Video on How to Replace a Pool Pump Motor which you may find helpful when you tackle this project. Reply

I'm trying to replace the motor on my pool pump but all these numbers and abbreviations on the motor label are really confusing me. What do they mean?

A  Answered on 1/19/2012 by InyoPools Product Specialist Patrick P.

Replacing a pool pump motor is not as difficult as it seems. You can try looking here. If you need help figuring out what the information on your label means. If you are still having difficulty figuring it out you can call us at our toll free number or you can send us a photo of your motor label here.

Can you direct me to the proper hi low switch for this motor?

A  Answered on 1/18/2012 by InyoPools Product Specialist Patrick P.

Unfortunately the manufacturer does not offer the switch for the 2 speed 220v motors any longer. If you already have a 220 volt timer (on/off) you would need an Intermatic T106R to switch from high to low speed. If you do not have a timer currently you would need the T10604R which is a 220v on/off timer and a high/low timer.

Why should I purchase a Tune Up Kit?

A  Answered on 1/12/2012 by InyoPools Product Specialist Patrick P.

A Tune Up Kit includes all of the essential replacement seals and gaskets for the pump. The seals and gaskets should be replaced when installing a new motor on your pump. New seals will prevent the pump from leaking water or losing the prime. A Tune Up Kit will protect your motor and ensure that the pump is working efficiently.

Why do I need to purchase a new shaft seal?

A  Answered on 1/12/2012 by InyoPools Product Specialist Patrick P.

We strongly recommend replacing the shaft seal. The purpose of a shaft seal is to prevent water from running down the shaft of the motor and into the motor housing. Water will damage the bearings and cause the motor to fail. A new shaft seal should be installed whenever a motor is replaced. The motor manufacturer can deny the warranty if the motor fails to due to water damage from a faulty shaft seal. To find your shaft seal you will need to visit our Pool Pump Parts Page or the Spa Pump Parts Page and select your make and model.

What is Service Factor?

A  Answered on 1/11/2012 by InyoPools Product Specialist Patrick P.

Service Factor(SF) is a multiplier that when multiplied by the horsepower of the motor indicates the total permissible horsepower loading that may be carried when the motor is operating at rated voltage and frequency. The most important thing to remember when replacing a motor is that the replacement motor's horsepower times its service factor must be equal to or greater than the original motor's horsepower times its service factor. The Service Factor rating can be found on the motor label. See Step 4 of our How to Read a Pool Motor Label guide.

Can you replace single speed pump motor with dual speed pump motor?

A  Answered on 5/16/2007 by InyoPools Product Specialist Patrick P.

Yes but you can't go with a higher HP than the single speed motor. For example if you have a 1 HP single speed you cannot go with a 1.5 HP dual speed motor; you would be able to use a 1 HP dual speed motor. Customer would need to purchase a toggle switch or timer to switch from high speed to low speed.

Pump Motor Burned Out.

Written on 12/6/2018 by Guest

The repair is fairly straightforward: I followed the repair guideline video on InyoPools.com and purchased the additional parts between the pump motor and pump, and in 30 minutes the job was done.
