I have a 2 year-old UST1252 motor. I believe the start capacitor is failing - perhaps the run capacitor as well. The pump generally does not start (hums and then shuts down and/or breaker trips) the first time after sitting for a while. Flow seems good once it runs and the impeller seems to move freely (I have only reached in through strainer side, have not removed the pump (yet). All that said, can you tell me the size/ratings for the capacitors? Thanks! Ken
I am looking to replace a pool motor UST 1252. Found in on your webpage along with tune-up kit. I was having pump leak problems at the seam between pump and main housing. Thinking of replacing at same time. Do you have a complete kit or only parts ?
Hi Mike, we may have a kit but we would need to know the make and model of your pump. This should be something like Hayward Super Pump, Hayward Super II, Jacuzzi Magnum, etc.. Could you please email back with your pump details.
I have a UST 1252 motor connected to a Hayward Super II Pump. This motor is about 2 years old. It has begun to leak around the top of the seal between the motor and pump. I did replace the seal using your GO kit, but it made no difference. Cleaned the surfaces real well and the bolts are tight. It is a fair amount of leakage and definitely from top area, not the bottom. Suggestions/causes? Thanks: Ken
The Super 2 series has been known to get leaks at the bolts where the housing meets the motor. The bolt ports are known to separate from the housings. If that is the case then you can use the pump housing repair tap set part number 5110-22.
Hi, again: Related to the question about the leakage below. The inserts appear to be fully seated, and the leakage appears come from mostly the very top center area - between two bolts. Any other possibilities? The pump itself is about 11 years old, but not sure what would have caused it to start leaking suddenly. Thank you; Ken
If the seals have been replaced and lubed then the only other possibilities will be those bolt inserts or the housing has been warped to the point that they do not seal flush with one another.
hi, i have a in ground pool about 38000 gallons i am using a haywood pump 1 hp the water flow is horrible. I can not turn on all jets (7) 2 floor-3 on the wall-2 at the steps-not enough pressure to push things to the skimmers. I want to upgrade to a 2.5 hp thinking it would be better but i noticed the rpms are the same what are your thoughts.
John, Any single speed pump will have the same rpms (3450). If you want to increase the horse power, you need to make sure that your filter and plumbing can handle the increased flow.

(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 at the Best Price
Reviewed By: peejmeister from Lucas, TX ()
Pros: Great price, quiet motor.
Although there was an initial glitch in getting this shipped, the Support team expedited it and got it out shortly thereafter. The motor installed easily (following the great how-tos on this site) and runs like a champ, and is extra quiet. I would recommend this motor for any application it fits. I've been very satisfied with its performance.
(4 out of 5 stars) Great swimming pool filter pump motor
Reviewed By: Janice T. from Franlkin Lakes, NJ ()
Pros: Reasonably quiet, long life.
Cons: Impeller removal is difficult and dangerous
The motor is great. I had to replace it for my filter pump only after 14 years of hard use. The motor could use an improvement where you have to hold the motor in place to remove the impeller. The back assembly needs to be removed and the starting conductor as well. I feel it could be easy to damage some of the parts in order to hold the motor in place while unscrewing the impeller. They could provide a small slot where a wrench can be inserted away from the conductor and wires.
