My Hayward Pump Motor 7-187582-02 (AO Smith motor) is humming but the impeller is not moving / pulling water in. How do I check the capacitor on this model?

Thanks for the quick answer re: the pump motor. The pump itself is a Hayward SP4015X20 with SER#21110908050927008. Are you able to tell the age from that or do I need to contact Hayward?
Hi, Mike. Your pump was manufactured in August 2009.
I have an A.O. Smith CAT- USN1202 / SERIAL 082093M / PART 7-193687-02 / TYPE CX / FR Y56J / HP 2.0 / SF 1.20 / HZ 60 / RPM 3450 / VOLTS 208-230/115 / AMPS SF 11.0-10.2/20.4 When we had a leak in the housing we were told that this pump had been discontinued. We found a replacement housing a few months back, but it has died today. We need to replace the whole unit and need to know which replacement to get?
Based on the motor model you have a Northstar so you can replace that model pump with the Tristar model SP3215EE.
My current motor is a O.A.Smith SP1615Z1MNSC, SF1.2, & Y56J frame. The serial number is 229093M. Is this AO Smith USN1202 the exact replacement? And what kit would be required? The motor is about 4 years old and the pump is about 15 years old
Mike, The USN1202 is the correct replacement for the SP1615Z1MNSC. In order to recommend the shaft seal, we will need to know the pump model.
my pool pump motor label showed: Part 7-187582-02 serial: CB01-31 the rest looks the same, DO YOU THINK IT'S THE SAME MOTOR?
Hi, Jason. This USN1202 is the correct replacement.
Hi, I currently have this pump motor, but I want to replace the entire pump and motor, will the SP2615X20 work?
Hi Jonas, normally the USN1202 is used on a Hayward Northstar Pump and if that is the pump you have then the Hayward SP2615X20 2 HP Pump would be a good replacement. I also really like the PL2603 PureLine Prime 2 HP Pump as it has 2" plumbing connections vs. the smaller 1.5" ports on the Super Pump. Either way you go you will have some slight re-plumbing as the plumbing ports on the pumps are not in the exact same location.
I need a replacement for my Hayward northstar sp4015x20ns pump, also need a motor shaft seal, gasket diffuser and plastic o ring. I see that the A.O. Smith USN 1202 is a suitable replacement for the motor, but how do I make sure I order the seal, gasket diffuser and plastic o ring correctly, to fit the a o smith?
Hi, Allison. The Century USN1202 Motor is the correct replacement, however, you will need to know when the pump was manufactured in order to locate the correct seals. If you can locate the housing serial number and call Hayward @ (908) 355-7995.
is the AO Smith USN 1202 the same as the Hayward SPX1615Z1MS? I have a Hayward Northstar 2HP pool pump model # SP4015X20NS, and I wanted to replace the motor. I notice you carry both motors but the AO Smith is cheaper. If it's really the same motor and will work just as well than I will order the AO Smith.
Hi Mike, Yes the USN1202 is the same motor and will work just as well. Go with the USN1202.
looking for capacitor requirements for the AO Smith SP1615Z1MNSC motor Does it use the same capacitor size requirements as the usn 1202 listed above part 5270-02
On the capacitor you need there will be a number starting with UF or MFD. Find out what your number is.Type it in in the search bar at inyopools.com.
Hi, This motor comes with a (1) year warranty from date of purchase.
What is the start capacitor part number for this motor?
Hello Fred - The USN1202 only has a run capacitor. The part number is 5270-02.
Would you recommend purchasing the seal tune up kit or just the heavy duty shaft seal (5250-250 (PS-4280)) when replacing this motor for a salt water pool? What is the part number for the seal tune up kit for this model pump?
Hi Red, The Heavy Duty Shaft Seal (PS-4280) would be the recommended choice to use in a salt water pool. There is only a Tune Up Kit for the 200-2007 Hayward North Star model not the 2008-current model. The PS-4280 can only be used on the 2008-current models, you would havr to purchase the seals separately.
Will this replace my Hayward northstar sp1615z1mnsc?
Mike- The A.O. Smith 2 HP Up Rated Northstar Replacement Motor (USN1202) will be a replacement for your Northstar pump, I would also recommend that you get the shaft seal for your pump so that you don't leak and void the motor warranty. The seal you would want is , 5112-216 (SPX3200SA), or you can get the salt water seal, 5250-250 (PS-4280).
I would like to order the 2-speed version of this motor. Thanks
Part number SPX1615Z2MNS is the 2-speed version of this motor.
What is the speed for this motor?
The USN1202 is a single speed motor. The RPM's are 3450.
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.
