How to remove impeller from motor?

Answered on 02/16/2015 by Product Specialist Robert M.

Our "How to Replace a Pool Pump Impeller" guide will explain how to remove the impeller.

Asked on 01/30/2015 by

I have a Haywood pool pump (SP2807X10) that seems to be overheating and is causing it to turn off automatically. Is the UST1102 motor the correct replacement motor? Thanks, SJ

Answered on 01/30/2015 by Product Specialist Robert M.

The UST1102 is the correct replacement motor for the Hayward Max-Flo SP2807X10.

Asked on 01/18/2015 by mike

What are the dimensions of the UST1102?

Answered on 01/19/2015 by Product Specialist Robert M.

Hello Mike - You can view all of the dimensions on our product dimensions image.

Asked on 01/18/2015 by Jeff

I'm replacing my Hayward Max Flo motor with your UST1102 and GOKIT1. Everything seems good, but in the on-line tutorial, it shows an impeller ring. I don't find an impeller ring. And I can't find a replacement on your site for my pump. Can I assume I don't need one??? Thanks!

Answered on 01/19/2015 by Product Specialist Alex V.

Jeff, The Hayward MaxFlo pump does not have an impeller ring. You will simply need the motor and the tune up kit.

Asked on 01/07/2015 by Jeff

I have a Hayward Max Flo 1HP pump. Is the UST1102 the correct replacement motor for this model? And which tune up kit do I need for this? Thanks!

Answered on 01/07/2015 by Product Specialist Brian M.

Yes, the UST1102 is the correct replacement for a 1HP Hayward Max Flo Pump.  The proper tune-up kit is GOKIT1 for the Max Flo.

Hello, I have a Hayward self priming pump model C48K2N143B1. Will the UST1102 motor serve as a replacement?

I have a Hayward max-flo pump self priming M # C48K2N143B3 1hp looking to replace this motor is the UST1102 the motor for replacement. Ed.

Answered on 10/27/2014 by Product Specialist Brian M.

Hello Eddie - That is the correct replacement motor. Make sure to get a new shaft seal as we. That is part number 5110-11 for the Hayward Max-flo. If you have a salt system, it would be seal number 5250-235. 

Asked on 10/24/2014 by Shane

I need to replace my Hayward 2 A.O. Smith pump motor. The model number is K48L2N104. This is a 1hp motor. Which replacement motor do you recommend? Are there a few I can choose from?

Answered on 10/25/2014 by Product Specialist Patrick P.

Hi Shane - Here is the Direct Replacement Motor for the K48L2N104 you would also have the option to upgraded to a Dual Speed Motor which typically saves you 50% on our operational costs over your current single speed motor. Here is the Dual Speed version of the K48L2N104.

I have a old Jacuzzi 94027110 and I want to know if this motor will replace the one I have? If so is there any special wiring or anything else that will need to be done or can I just take the old motor off and put this one into the housing and wire it? I would rather not buy a whole new pump unless it is absolutely necessary.

Answered on 07/10/2014 by Product Specialist Patrick P.

Yes the UST1102 would be the replacement motor for your 1 HP Jacuzzi Magnum pump and there would be no different wiring required, we would suggest a Jacuzzi Magnum tune up kit when replacing your motor which includes a shaft seal, o-rings, gaskets and lubricant. Typically if you use your old shaft seal it will not mate up properly which will cause leaking.

Asked on 07/10/2014 by Guest

I need to replace the motor on a Hayward Super Pump 3/4 hp. Can I go up to a 1 hp and what difference does that make? If so, does anything else need to be changed out? This is for an inground 16' x 32' pool.

Answered on 07/10/2014 by Product Specialist Patrick P.

You could go up to a 1 HP motor which would give you a higher gallon per minute rating (GPM). On a typical pool a 3/4 HP Super pump will have an output of 50 GPM's where a 1 HP will have an output of 65 GPM's. You would want to make sure that your filter could handle this increased flow rating from the 1 HP motor your filter should have a label on it which says max flow rating, this would let you know how many GPM's the filter can handle. If you increased your motor to 1 HP you would need to also replace your impeller to a 1 HP impeller, we would also suggest a Super Pump tune kit.

Will the AO Smith UCT1102 cost less to run than the UST1102?

Answered on 05/02/2013 by Product Specialist Patrick P.

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.

Asked on 02/28/2013 by Guest

Are all pool motors wired the same?

Answered on 02/28/2013 by Product Specialist Patrick P.

No. The motor should be wired following the wiring diagram on the motor itself.

Asked on 01/24/2013 by Guest

My pool pump motor makes a humming noise when I try to start it. Will replacing the motor fix my problem?

Answered on 01/24/2013 by Product Specialist Patrick P.

Replacing the motor should solve your issues. Aside from the motor, you will need a GOKIT to replace the seals on your pump.

Asked on 01/18/2012 by Guest

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.

Answered on 01/18/2012 by Product Specialist Patrick P.

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?

Answered on 01/12/2012 by Product Specialist Patrick P.

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.

Asked on 01/12/2012 by Guest

Why do I need to purchase a new shaft seal?

Answered on 01/12/2012 by Product Specialist Patrick P.

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.

Asked on 01/11/2012 by Guest

What is Service Factor?

Answered on 01/11/2012 by Product Specialist Patrick P.

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: 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.

   (3 out of 5 Stars) Product Received from Century Motor not AO Smith

Reviewed By: from CT ()

Pros: Price, delivery, fit

Cons: durability?

It is clearly labeled and sold as AO Smith. I received a box and motor from Century Motor made in China. It is not AO Smith but a generic brand. I attempted to buy a product with "AO Smith" Brand name on it. My original motor was made by AO Smith not by Century and was labeled as such. While this fits and is working, only time will tell if this product will last ten years like the real AO Smith motor did. I will know by 2024 if I still own this home or if the motor fails before then! I had a great experience with the real AO Smith product and now have to "HOPE" for the same with this Chinese product. Feels like a "bait and switch" to me.
