I'm trying to find a cover that goes over the electrical connection and over the capacitor at the back of the motor. Model USN1102. Do you guys happen to sell one separately? Has two screws to hold it down.
Good morning Mark, I apologize we do not have those replacement end caps for this motor available at this time.
I have a sp4030ns 3 hp
Its overkill for my pool. The pool had a 1 hp pump. Any chance I can replace the motor only to a 1 hp? Do I need to change the diffuser?
Hi Francisco, when it comes to sizing a pool pump there are a number of variables to consider. Here is a guide that we put together called "How to Size a Pool Pump for Your In-Ground Pool" that may assist you or you may want to at least consider having a CPC(certified pool contractor) perform a site evaluation to better confirm as well.
Any way to make this motor work with a Hayward SP4010NS pump with (standard) 1.0hp-rated impeller? Would replacing with a 0.75hp impeller make any difference (if this is even possible?!)?
I want to replace my motor: SPX1607-1-MNSC W/ sf 1.4. Which of the two motors should I order: The -mnx, or the - Full Rated BNS? What is the difference?
How can I identify my Howard Pump model. There is a serial number plate, but it's not legible (for ordering the rebuild kit? Thank,
Hi, Art. You should purchase the MNS replacement motor USN1102. The difference between the two is the total horsepower. You have a NorthStar Pump model SP4007X10NS. You can call Hayward with the serial number to find out if the Hayward Northstar 4000 Series Pumps Tune Up Kit (Pre-2003) - GOKIT66 will work for your pump.
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.
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.
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.
Why should I purchase a Tune Up Kit?
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?
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?
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.
(5 out of 5 stars) Excellent Pump Moter Replacement
Reviewed By: PoJo from Clarence, NY ()
Pros: Awesome fit - excellent replacement
Tip to get the impeller off the old pump moter: use a 7/16" open ended wrench - it slides in near the capacitor on the electrical side... rotate the impeller until the wrench slides into place at the end of the shaft and then one person holds the motor and the wrench while a 2nd person loosens the impeller off with bare hands by turning the impeller counter clock-wise.
(5 out of 5 stars) great motor
Reviewed By: Mike from Palm Coast, FL ()
Pros: ease of self repair, customer service, solid motor
Cons: as with anything, a little less expensive would be cool, however saved the difference and more installing it myself
Exact replacement for what I needed. The customer support was phenomenal. This was the first motor I replaced myself and couldn't have done it without the phone support. I recommend Inyo pools to anyone doing any pool repairs or work.
