Will the Energy Efficient 1 HP UCT1102 motor be a direct replacement for my 1 HP A. O. Smith ST1102 (1081 Design) motor and does it come with a shaft seal or must I order that separately? I already have a 3-piece Hayward pump seal kit. Thanks, Dale
Hi Dale, This UCT1102 is not a replacement for your ST1102 Motor. Please click this link for the UCT1152 Energy Efficient Replacement Motor that you will require. Your ST1102 motor is a 1 HP full rate motor which is equivalent in power to the UCT1152 motor which is a 1.5 Up Rated Motor. The motor does not come with a shaft seal. I'm not sure which Hayward Pump you have so I can't make a suggestion on a seal, the most popular Hayward Pump is the Hayward Super Pump, if you have a Hayward Super Pump then you will need this Hayward Super Pump Shaft Seal.
1) What other parts will I need to buy when replacing the motor - New impeller, seals? 2) Will this motor work as a replacement to: SP-1605-Z1-M Model: C48J2N122 SER C77 Volts 115/230 RPM 3450 Amps 10.6/5.3HP 3/4 FR 56J
Hi, Matthew. I would recommend getting the pump seal and the o-rings but I will need the model number of the pump housing. The correct replacement motor for the C48J2N122 motor is p/n UST1072.
Can I use this energy-efficient motor on my existing 115V/15 Amp GFCI circuit?
Hi, Georef. You can if this motor is the only equipment being used on that circuit.
The SF of this motor is 1.0 where the SF of UST 1102 is 1.10 I thought that the SF of the replacement motor must equal or exceed the previous motor...
Nate you are correct however since the SF difference is so minimal we have not seen any issues using the UCT1102 as a replacement for the UST1102. The manufacture Century also promotes the UCT1102 as an energy efficient replacement to the UST1102 and you would have the full 1 year warranty if using this motor as a replacement to the UST1102.
is this the same as c48k2n143 ?
This is an energy efficient version of that motor.
Can I use this motor to replace an AO Smith C48K2N117A9
Kim, Thank you for your question. Can you please attach a photo of the existing motor label? There are some specs we will need to confirm.
Replacing my C48L2n134c2, is this the correct replacement motor? Also, can you confirm the seal kit? Thanks
Hello - the correct direct replacement motor is the A.O. Smith 1 HP Full Rate Round Flange Motor - ST1102. If you want the Energy Efficient alternative, you can use the A.O. Smith 1 HP Energy Efficient Round Flange Up Rate Motor - UCT1102. The seal kit is based on the make and model of the PUMP you have (not the motor). You will need to identify the pump information in order to determine the correct seal kit you need.
will this be an exact fit to replace a Hayward model number C48K2N143B1 1 HP KW .75 115/230 volts SP1607Z1-M
Hi Joey, Yes, the UCT1102 is the energy efficient replacement to the C48K2N143B1 motor.
I want to replace my dead motor Model # C48K2N143B1 with a more efficient one. I was wondering if I should get the UCT1102 or the UCT1152? Thank you, for your time and help in advance.
Hi Angie, The energy efficient version of your C48K2N143B1 motor would be this UCT1102 motor and this would be the correct replacement for you.
The run capacitor hump housing on my UCT1102 is completely rusted out. Is there anyway of finding a replacement part?
Hello, Please provide the specs and dimensions of your existing capacitor.
Additional info......capacitor is 161-193MFD.
Hi, If you're needing the replacement capacitor the BC-161 will be the correct capacitor.
do you sell bearing repair kits. Model # K63CXEPY-4766. it is made by U.S. Motor
Hi, We do not have the bearing info for the U.S. Motors, I would recommend contacting U.S. Motors at 888-637-7333 for assistance.
What other parts such as a new seal should also be installed when putting in a new pump
This will be dependant on the condition of the other parts. You may need to replace some of the other seals and gaskets as well. Usually we recommend to purchase the entire seal kit just in case they are needed. The kit type would be dependant on the model of the front pump housing. It would also be wise to inspect the impeller as well for any damage or cracks.
Is this motor now made by Century???
Technically, yes. A.O. Smith and Century Motors merged into a larger manufacturing company called Regal Beloit. The sticker on the motor may say, A.O. Smith or Century.
Hello! Does the UCT1102 motor have a built in timer? Thank you!
Hello Kent - The UCT1102 does not have a built in timer.
I am looking to replace an ST1102 1HP motor on a Hayward Superflow pump. I think I would like to upgrade to variable speed for more energy effeciency. I see the STS1102 and UCT1102 and was wondering what the difference is? Also, it appears that I would need some additional parts, like a timer or special switch, is that correct? I also have to ensure that the replacement motor is the exact same length as the installer left me barely enough room to extract the motor. Thanks for your help!!!
Hi Wayne, The STS1102 is a dual speed replacement motor and the UCT1102 would be an energy-efficient single speed motor, neither of these would be a variable speed motor. Here is the link to the Variable Speed Motor for the Hayward Super Pump, the variable speed replacement motor does have a controller so no additional timer would be needed. We have Detailed Dimensions of the Hayward Super Pump Variable Speed Replacement Motor here, I would take a look at these dimensions to determine if this motor will work for you. We would also highly recommend a Hayward Super Pump Tune Up Kit when replacing your motor.
Will the AO Smith UCT1102 cost less to run than the UST1102?
Yes, the UCT1102 will cost less to operate compared to the standard UST1102. Depending on how the motor is cared for, it should last several years. When replacing the motor, I would recommend buying a tune up kit based on your pump model and age.
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) Perfect replacement motor

Pros: Great company to work with.
Great customer service, price and delivery. If you live in FL, use ground shipping and you will still recieve product by next day (if in stock). This is the high efficiency version of the motor I originally had. Works just as well as the original and uses less electricity to run.
(5 out of 5 stars) Great Motor
Reviewed By: Steve B. ()
Pros: quiet energy efficient
So far have had it installed for about a week. Replaced an A.O. Smith UST1102 motor that had bearings go on it. This new motor is VERY quiet, I also ordered a new impeller and the gasket kit to redo everything up to the pump. This was my first time doing it myself and it went great. The youtube vids from Inyo were a great help.
(4 out of 5 stars) quiet running motor
Reviewed By: tank from Kenton, TN ()
Pros: good fit, helpful videos
Cons: poor packing, inspect motor first
WATCH the video on replacing the pump motor before starting! They are very helpful. Motor was easy to install, direct fit with the enclosed 1/2 inch spacer block for older Hayward Super Pump. Get the tune up seal kit and replace when doing motor, not worth the hassle of having to go back into it. (Videos for this too) My only reason for not giving a 5 star rating is the 1st motor I received was locked up and would not run, bench test before installing. The replacement I received was fine, don't know when I've heard my pump this quiet!
(5 out of 5 stars) Easy install/fast shipping
Reviewed By: Kirsten I. from Elk Grove, CA ()
Pros: quiet, great price
We ordered this pump as a replacement for our Hayward Super Pump II, 1 HP, which finally died after 8 years. It was an easy replacement and is super quiet. I upgraded the shipping to 2 day and called customer service right after I placed my online order. The rep I spoke with was very friendly and got it taken care of right away. My pump arrived on the day they said it would and it was quickly installed.
(5 out of 5 stars) RUN QUIET
Reviewed By: pool boy from Lakeville MN ()
Pros: uses far less power
I replaced my standard motor with this high efficiency motor. It uses almost half as much current as the standard motor. I was surprised how quiet it ran. when I purchased this motor I also purchased the shaft seal. I was glad that I ordered the shaft seal, since mine was shot when i took my pump apart to replace the motor. The reason my motor quit was because of the leaking shaft seal. So i recommend buying a new shaft seal when replacing the motor. So far I am very happy with this purchase.

INYOPOOLS was great in helping me locate the proper motor for my pool. Not only did they ship immediately, (I received it the next day) but they also sent me all the instructions for assembly of the impeller, seal kit, etc. to assist me in its installation. When I discovered that I also needed a new diffuser the following day, they sent it right away and I received it the next day. I am so pleased with my first experience with INYOPOOLS that I have recommended them to my friends. Great Job!! Thanks
