Hi, Lee. Yes, the SQ1102 standard motor or QC1102 EE motor can be used with the P4E6E-187L pump. You will need the Impeller C105-238PB, and the Shaft Seal Pre-1997 (U109-372SS) or Shaft Seal After-1997 (37400-0027S) (without Seal Insert).

I have an A O SMITH motor Model C48k2 ra104a3, (AS FAR AS I CAN READ), USG1102, 1HP this motor works but not pulling water to the irrigation pump, took it apart and impella assembly needs replacing. Do you have these parts or give me info. Thank you

A     Answered on 11/8/2016 by InyoPools Product Specialist Scott W.

To identify the correct replacement impeller I will need the pump model, not the motor model#. If you do not know what that is, if you attach a picture of the pump I can try to identify it for you. We do not really deal too much with irrigation pumps, but I will see what I can do by looking at the picture.

I have an 20+ year old Sears Centrifugal pump Model 390.262501. It has an A.O. Smith motor 1.5HP C48L2EC11 which shows as a cross ref. for this motor. The wet end of the pump is relatively new and I believe the original pump was STA-Rite mfg. Is there anyway you can tell if the SQ 11O2 is a good replacement to fit the wet end?

A     Answered on 10/5/2015 by InyoPools Product Specialist Lennox H.

Hi Paul, The A.O. Smith 1 HP Square Flange Full Rate Motor (SQ1102) will replace the current motor that you have with the mod # C48L2EC11. It will also fit onto the wet end of the pump that you have.

?     Asked on 9/16/2015 by Michael

I see the "tune-up" kit contains the motor shaft seal which is essential to be replaced with the motor, but also contains a housing gasket, diffuser gasket, and pump lid o-ring. Do all of these need to be replaced with the motor? If think the housing gasket is for the impeller housing (not the motor), the pump lid o-ring goes on the clear plastic lid which screws on the basket in front of the impeller (also not related to the motor) and I'm not sure what the diffuser gasket is for.

A     Answered on 9/17/2015 by InyoPools Product Specialist Andy O.

Michael, The kit contains o-ring associated with the pump. Since the motor is more or less generic (it fits onto multiple pumps), the seals would all be based off and related to the pump. There is usually a shaft seal that goes behind the impeller and in the seal plate (part of the pump that bolts to the front of the motor), the diffuser o-ring is for the cone like part that goes over the impeller, the housing gasket which is for the body where the two halves of the motor match up. It is highly recommended that you change the shaft seal every time you take off the impeller. As for all the other seals, they are recommended but optional, it just gives you a change to do a complete overhaul on all the gaskets on that pump.

I have an AR205-L Anthony pump, it's a one horse A.O. Smith. Will the AR206-L replace it? Thanks.

Hi, The A.O. Smith 1 HP Square Flange Full Rate Motor (SQ1102) will be the correct replacement motor for the 1 HP Anthony AR205-L Pump. You will also need to replace the Shaft Seal (U109-93SS-50).

?     Asked on 5/4/2015 by tony

I now have a square flg.motor. will any square flg. motor fit my pump

A     Answered on 5/4/2015 by InyoPools Product Specialist Patrick P.

Hi Tony, To determine which motor you would require we would need to know the model of the pump itself, this should be on the side of the pump near the basket. We would need the manufacture name and model # of the pump. Examples of the Manufacture would be Hayward, Pentair, Purex, Sta Rite, Jacuzzi, etc... Examples of model names would be Super Pump, Super II, Whisperfo, Magnum, Dura Glas etc.. Please provide this information along with any of the following information Horse Power, Volts, SF, RPM & Amps and we will be able to determine which motor you would need.

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?

A     Answered on 1/12/2012 by InyoPools 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 1/12/2012 by Guest

Why do I need to purchase a new shaft seal?

A     Answered on 1/12/2012 by InyoPools 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.

What is Service Factor?

A     Answered on 1/11/2012 by InyoPools 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.
