I have a model #SP4007X10. Is this the correct replacement motor? What is the tune up kit for this also?
For the SP4007X10 Northstar you will require the USN1102 1 HP Up Rate Replacement Motor To be able to suggest the proper seal kit we would need to approximately what year your pump was manufactured.
Would your pool motor hum if the start capacitor or start switch is bad? If so how do you test the capacitor or switch?
Hello Jerry, we have a lot of videos on replacing the capacitor, but none of testing capacitors. Humming from the motor is because the capacitor has gone bad. If you would like to see How To: Replace Your Pool Pump's Capacitor or Poolside Chat Episode 42: Pool Pump Motor Capacitors.
To remove the impeller,does it come off clockwise or counterclockwise
Hi, John. To remove the impeller from the motor shaft you will need to rotate it counter clockwise.
Hi, I have a Hayward Northstar Pump Assembly for my inground pool. Is the SN1102 the correct replacement motor for this unit. The original AO Smith Century motor says SP1610Z1BNSC on the data plate. Thanks.
That would be the correct replacement, but you could also go with part number 5112-052.
I replaced the capacitor and rebuilt the pump just 2 months ago and was working better than ever but the motor just started screaming yesterday. I can only guess the it had overheated when I had the initial issues and now the bearings are shot. My plan is to go ahead and replace the motor. Well I need a new tune-up kit or well the one I just installed be fine? Thanks
Hi Kirk, You will not need another tune up kit if it's only 2 months old but I would recommend getting another shaft seal just to be safe.
What is the warranty on motor. SN1102
Hi Brandon, This comes with a 1 year manufacture warranty.
My pump is a Hayward Northstar SP4007X10NS. Is this the correct motor replacement? Also, which go-kit do I need for this pump?
Bary- The replacement motor for your model pump is the USN1102 A.O. Smith 1 HP Up Rated North Star Replacement Motor. As for the go-kit we would need to know what year the pump was installed.
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) Perfect Match!!

Pros: website, delivery, product selection
This motor is the perfect fit for my Hayward Northstar 1HP Pump. I had to get the Impeller kit with the pump seals as my old impeller would not come off. I had to use a metal grinder on a rotozip to cut the impeller off so I could reuse the motor mount and the seal plate from my old motor. INYO delivered the motor, Next Day, for me so I could get the motor installed and my pool back in shape. Great Service!!

Pros: Does what it needs to do.
This motor was exactly what I needed for my pool, and much cheaper than what I could purchase locally. The first one I ordered broke down after a few months, so I am hoping this one is more reliable. So far so good. Also, INYO sent me this new motor at no additional charge.

Great delivery. Ordered Labor Day (Monday) and it was delivered Wednesday. Installed easily. Good website. I had problems on other sites trying to determine what motor and parts I needed. Inyo site was clear and easy.
