re. Century USQ1252 K48N2PA105C5 I am trying to replace the bearings and can't seem to find the correct part numbers. The front bearing is a different size from the rear bearing. Can you help me out with the part numbers? Do you carry them or should I purchase them locally or on line from a bearing supplier. What is the cost? Thanks.

what is the seal kit part number for this motor
Reply
To determine the proper seal kit we will need to know your pump make and model information, common pump names would be Pentair Whisperflo, Pentair Challenger, Jandy Stealth, etc.. To supply this information click the reply link below, also if you could send a few photos those are always helpful as well. If you send photos then take a close up shot of the motor label as well as a wide shot of the complete pump to include the pipes going in and out of the pump. To supply photos simply click the reply link below and upload your photos. Once we get any of this information we can make the proper recommendation.

Hello, I have a Pentek AE100GLL motor for my sprinkler pump and I think the ball bearings are stuck. Will this motor be a good replacement for my current.

This looks like the motor I need for my Cal Spa Dyna Max Pump. But the one I need to replace is two Speed. Does it come in two speed also ?

I Have a Starite Max E Pro P6E6G-208L. Motor Model number K48N2PA105 2.0 SF 1.3. I think the USQ1202 dimensions will work better( so it doesn't change installed hight to pump housing) but that motor may be slightly under powered at 2.0 SF 1.1 Are both of these Energy efficient rated?

Good morning Steve, You need a A.O. Smith 2 H.P Square Flange Full Rate Motor - SQ1202 It is not EE but at 230v it is only running 11amps. The only EE that will work is a 56Y frame which means the motor will be thicker. But it's running 10.2 -11amps so there is not much of a difference energy wise. that would be a 2 HP Motor EE - Full Rate (B843, B2843)

I need a new motor for a 5 year old Hayward Tristar SP3220X25 2-1/2hp pump. Would this pump fit and is there a salt water tune up kit for it also. TY
Reply
Hi, Takopoke. Yes, this motor (USQ1252) will fit the Hayward TriStar SP3220X25 pump. There is not a tune up kit for this pump, the seals will have to be purchased separately. You can locate all the parts on the Hayward TriStar Pump Parts page.

Thanks for the quick response about which motor is appropriate for the Jandy FHPM2.5. You mentioned that either the 56Y or 48Y will work, with the difference being the barrel motor size being 1" different. Is there any benefit of one over the other? Also, which Shaft Seal or Tune-Up kit would be used for either (or both) of the motors (USQ1252 and B840)? Thanks again.

Hi Robert, There is not benefit of one over the other, their is not a tune up kit available for this pump. You can find the replacement shaft seal and o-rings needed for your pump via the Jandy Flo Pro Pump FHPM Parts.

I've got a Jandy Flopro 2.5 HP pump which is about 5 years old. The motor was replaced about 2 years ago with a USQ1252, which is a 48Y Frame Square Flange model. Now the motor has gone bad again. When I looked at the user's manual, however, it says that an appropriate replacement motor is a B840 56Y model. Now I'm really confused - do I need a USQ1252 or a B840?
Thanks for your advice!

Hello Robert, You can use either motor. The USQ1252 A.O. Smith 2 1/2 H.P Square Flange Up Rate Motor (USQ1252, C1284, B884) and the B840 A.O. Smith 2.5 HP, 56Y Frame, Up-Rate Motor (B840, B2840) will both fit. The only difference is the USQ1252 is a 48y and the barrel of the motor is 1" in diameter smaller than the 56y. But both will bolt up the same and work the same.

Hi I'm trying to repair a USQ1252 motor, the problem is that the capacitor has gone bad but I can't identify the range of microfarads of the capacitor, can someone tell me what capacity should the capacitor be for this motor????

Hello Adrian - The run capacitor is 370v and 30 MFD. The start capacitor is 250v and 36-43 MFD.

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.

Why should I purchase a Tune Up Kit?
Reply
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?
Reply
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?
Reply
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
Cons: none
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 Replacement
Reviewed By: Takopoke from Green Valley,Nevada ()
Pros: Perfect fit
Cons: none
This was a perfect replacement for my 5 year old Hayward Tristar pump,model SR32202. Had to order all seals,gaskets and o-rings separately because there were no go-kits for this model pump. The total price of everything including the lube kit was less than buying a whole new pump!!! Great instructions on INYO'S website made it pretty easy too! TYTY

Pros: Fast replacement of damaged goods
The pump arrived damaged. It had apparently been dropped by the delivery service. I contacted INYO Pool Products and was impressed by their ability to get me a replacement the very next day. This alone means that I will recommend them.

Reviewed By: Doninfla from Sebring, FL ()
Pros: Price is right, shipping is outstanding.
Cons: Made in China.
Great customer service people, outstanding prices, and immediate shipping. Nothing to complain about. The motor was an EXACT fit, and I had no trouble replacing the dead motor. It seems to be running about the same temperature as the old (American Made) motor.
