I currently have a Century ST 1202 Model Num. K48N2N106C1 motor that runs an irrigation pump. I had one that lasted 10 years then the next one lasted 2 years. the one I have now burned the winding's in 3 weeks. Is there a more heavy duty motor I can upgrade to?
Marty, Based on the specs of the ST1202, the comparable motors will not be as "heavy duty" as what you have now. I would recommend staying with the ST1202.
I have a K48N2N104. I am looking at your site: http://www.inyopools.com/Products/00200017001213.htm?Keywords=k48n2n104 I would like to buy a motor with a bit more power 2.5hp. Do you recommend this? Which model would recommend?
Hi, Hoss. The K48N2N104 motor has a total hp of 2.6 hp so if you're looking to step up the motor you'll need the ST1302 motor.
Hi, I have a Century Centurion 2 hp, 230v motor, The pump is an American Products Co. Model #38298. The motor still runs good but the impeller that is bolted to the motor is making a very loud noise. I would like to get a new motor and impeller/pump. What can I replace that with? Thanks, Doug
Hi, Doug. They are different 2 HP motors available and I was not able to locate an American Products pump using that model number. Please send us pictures of the motor label and of the pump housing so that we can try to identify the replacement motor and pump.
I have a motor that went out and I'm trying to find the correct replacement. Your help would be appreciated. My pool has a Jandy pump model# JHP2.0, Serial # 0834. Can you point me to the correct motor? Your assistance is greatly appreciated.
Hello Jennifer- The correct replacement motor for your JHP2.0 is the Motor 56j Thrd Full 2 Hp - B836.
My old AO Smith pool motor burned out model # K48M2N110 at 1.5 HP, can I replace upgrade to the ST1202, 2HP unit? And if so, is this the correct impeller to upgrade to? Sp3021-c
If your current pump is a Hayward Super 2 then yes, that is the correct impeller to upgrade with the ST1202. That is fine to do that as long as your filter is able to handle the increased flow rate.
I have two ST1202 pumps, both are models K48N2N, HP, 56J, 1.33, etc, except one is 11.2 Amp, and the other is 12.6-11.4 amp. Question 1: my 11.2A pump is leaking very small of water at the hump on top of the pump, and it shuts off itself every hour or so. Do I need to replace the motor or just a seal somewhere? Question 2: if I need to replace, would the 12.6-11.4 amp model work? Thanks
Hi Josh, Yes, I would recommend that you replace the motor and the seal within the pump and the ST1202 Motor with the Max Load Amps of 12.6-11.4 will work.
Hi My pump give a load noise, I cleaned it but still has same noise, sometime very load. I am listing here the model number and looking for the correct motor replacement , to help me lower this nose.

Hi Mohamed, The UST1202 is the correct replacement for model # K48M2N111.
I have a super II Hayward 2 hp pool pump. Motor Model # C48M2N111A3 "smith motor". Sounds like the bearing are going out, can you tell me the replacement motor I would need? This is the 3rd time I have replaced it in 8 years of owning the pool. Thank you
I have a motor that went out and I'm trying to find the correct replacement. Your help would be appreciated. My pool has a Jandy pump model# SHPM2.5 Serial # n08FB3380 HP 2.5. The motor is HP2.5xS.F1.04= Total2.6 Can you point me to the correct motor? Thanks!
Hello Jennifer, The replacement motor you are looking for is A.O. Smith 2.5 HP, 56Y Frame, Up-Rate Motor (B840, B2840) B840.
I am ordering a ST1202 pump, and would like to order a new impeller as well. What is the model number for the appropriate impeller? Is there any way to get them shipped assembled?
Al- The ST1202 motor will fit on several different pumps, in order to find the correct impeller for your pump we would need the model of the pump. And unfortunately, they will not come assembled.
Is there any advantage to upgrading from a ST 1202 to a ST 1252? And if so, do you have to change the impeller?
The ST1202 and UST1252 have the same total hp so you would not need to replace the impeller. There is no real advantage in changing the model.
is the rotation on this motor CWLE?
Hi, The A.O. Smith Round Flange 2 HP Full Rate Motor (ST1202) rotates CCWPE.
I purchased and received the motor above to replace a very loud motor with the description as follows:. A.O. Smith, type :cx , Frame: Y56J, HP:1.5, SF 1.0, Volts: 230/115, Code: E, model: 0-184982-23 Is not installed. Will it fit and work ok?
Hello Larry - The motor would fit. However, you would need to upgrade the impeller and possibly the diffuser. These parts would depend on the make and model of your pump.
What is the difference between ST1202 and UST1202 other than the price.
The ST1202 is a full rated motor with a total HP of 2.6 and the UST1202 is an up-rated motor with a total HP of 2.2.
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.
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 pump
Reviewed By: Jason B. ()
Pros: Price, quality, shipping, customer service
inyopools.com is awesome. Best price on the internet and pump is excellent quality. Just make sure you get the correct unit. The model numbers seem to change over time and can have different HP ratings.
(5 out of 5 stars) Excellent replacement motor
Reviewed By: Thomas Z. from Southern California ()
Drop in replacement for my existing Hayward pump. All of the literature and drawings posted on inyopools were very helpful. Do note that the mounting threads on this motor may be different from your current motor so check out the posted drawing and get 4 bolts before the motor arrives. My old motor was 1/2"-16 while this one is 3/8"-16.

Pros: Perfect swap, good price
Cons: have to add capacitor from old pump (may only be for my application)
Second time we ordered this particular unit, as we have three. These are great replacements and price is fantastic. Ordering 3rd unit today, now they will all work!
(5 out of 5 stars) Replacement Pump Motor
Reviewed By: David R. from Corozal, Belize - Central America ()
Pros: Well built, straightforward motor
Cons: Comes with no instructions or power cord to hook it up.
The AO Smith Round Flange 2HP Full Rate Motor is a hard-working piece of gear. Without the benefit of having taken my old pump motor off of the pump and having partially disassembled the old motor, I would have been hard pressed to install the replacement as it came with no instructions. It also didn't come with a power cord or a grommet where it exits the motor housing. There are instructions that can be downloaded from a couple of forums on the Internet however. If you have limited experience with electrical stuff, don't attempt it on your own. Oh, the last thing. Packaging was totally inadequate for international shipping. Thankfully, it's one tough motor.
