What is Service Factor?
 Reply

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.

Why do I need to purchase a new shaft seal?
 Reply

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.

Why should I purchase a Tune Up Kit?
 Reply

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.

I'm trying to find a replacement motor for my pool pump but my model number doesn't match what you have listed as the model number. My model number begins with a C48 and yours begins with an SP. Please help.
 Reply

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

What we have listed on our chart pages is the pump model number. The model number you have will just identify the motor. If you look on the plastic housing on the pump there should be a sticker which will have the pump model number. You can usually find this by the discharge port on the pump. Once you locate it you can choose the correct replacement motor. Be certain to change the shaft seal and gaskets as needed. You can use our >How to guide if you need help.

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?

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.

Hi, The replacement for my current motor is listed as UST1072. It seems the only difference from the ST1072 is the service factor. Can I use an ST1072 instead of a UST1072 or is the service factor a game breaker?
 Reply

A  Answered on 4/22/2016 by InyoPools Product Specialist Hector F.

The ST1072 is a stronger motor so you may need to change the impeller if it was originally set up for the UST1072. Also the filter may not be able to handle the extra water pressure.

Does this motor have a starter capacitor under the motor housing? If "yes" what is the replacement part.

Yes this motor does have a start capacitor which is located underneath the motor cover on the back of the motor. The capacitor # for this motor is a 610807-002 Start Capacitor We also have a Video on How to Replace a Pool Motor Start Capacitor which you may find helpful.

I'm looking for the proper replacement booster pump for a Hayward Model 5060 series 8d07. The current motor has a SF of 1.85 and a HP of 3/4, totalling 1.3875 HP. According to your own info replacement motor HP should be equal to or greater then the original. But the motor you list as the replacement In another Q/A for the 5060, is the SPX2707Z1M with a square Flange. Also you list the ST1072 which has a round flange. Neither meet the HP requirment as my current motor. So which is it?
 Reply

A  Answered on 4/25/2017 by InyoPools Product Specialist Scott W.

Hayward has part number SPX2707Z1M for the replacement motor for that booster pump, but you could also use part number SQ1072 for that booster pump. Also, that booster pump requires a square flange motor not a round flange motor. The shaft seal you will need for your motor install is part number 3260-105.

I have a leak on my Hayward booster 5060.. when I turn on the booster the leak appears to be a pressured stream coming from the seam of the volute. Will this leak compromise the pumping or suction action on my piping system even when not activated? (It does not leak when not in use)
 Reply

A  Answered on 2/21/2018 by InyoPools Product Specialist Lennox H.

Hi. If the leak is not resolved it will get worst causing a major issue with the pump, and or the performance of your cleaner. It may not be an issue when the pump is not running but it just depends on the severity of the leak.

whats the difference between a st1072 and a ust1072
 Reply

A  Answered on 6/9/2018 by InyoPools Product Specialist Alex V.

Hugh, The ST1072 if a full rated motor (high service factor) and the UST1072 is an up-rated motor (low service factor). You need to match the horse power and service factors among other specs to make sure you are buying the correct motor.

Hello Ruben, yes if you match the specs on the motor they should be the same. The serial numbers would be different like a VIN number on a car. Based on the photo you would need the Tune Up Kit Hayward Super II - GOKIT2.
