I have a Sta Rite Max E Glas 3/4 horsepower pump, model # PE5D-181L, that is a single speed pump used for a waterfall and two fountains and I need a new motor, as the bearings in mine have gone out and it is very loud. The part # for the motor is K48K2PA105C1. Do you have one or one that is compatible?

A  Answered on 3/11/2022 by InyoPools Product Specialist Craig C.

Replacing a STA-RITE MAX E PRO P6E6D-205L (k48k2pa105c1), is this 1-1 replacement? Gokit79? Anything else recommended? Thanks in advance!

 Reply

A  Answered on 1/13/2022 by InyoPools Product Specialist Rich N.

Hi Chris - the QC1072 motor will be a perfect replacement for the k48k2pa105c1 on your Sta-Rite Max-E-Pro Pump, and the GoKit79 Tune-Up Kit will let you replace all of the worn-out o-rings and the motor shaft seal when you change it out.  Be sure to keep the sticker from the capacitor housing so you can remember what the model number of the pump is, but be careful if you remove the housing; the capacitor will hold an electric charge and can be dangerous.

Hi, Can you please help me with the tune up kit for this pump with a badly damaged label?

 Reply

A  Answered on 4/10/2020 by InyoPools Product Specialist Hector F.

You will need to use the GOKIT54 that you can view by clicking here. Please be advised that if you have the copper cone insert in the seal plate it will need to be removed.

I just ordered this new pump do i need new seals
 Reply

A  Answered on 8/13/2019 by InyoPools Product Specialist Jessica C.

Hi, William. We recommend that you replace the shaft seal as well when you replace the motor. To determine the shaft seal you need, I would need the model number of your pump which is located on the plastic pump housing.

I am needing to replace an A.O. Smith #U27-1235 #K48K2PA105C1 motor with SF 1.65, HP .75, FR 48Y specs. It is mated with a P4E6D-186L Max-e-glas lol pool pump. It was installed in 2001. What is the best replacement motor for this and and more energy efficient with less amps used? Is my old motor an ‘up rated’ or ‘full’ rated motor? Thank you.
 Reply

A  Answered on 6/27/2019 by InyoPools Product Specialist Kevin G.

Hello,The 5321-1 is the best model to go with. Also, you will need the GOKIT38 to replace your seals.

Hello, I have a sta-rite pump model # RE5D-181L. The motor started overheating at the end of last season. It looks like the QC1072 motor is the correct replacement, can you advise the pump-seal part #? I have attached a couple of reference pics. Also - Does it make sense to just replace the motor, or should the whole pump be replaced? Thank you, Rob

 Reply

A  Answered on 4/11/2019 by InyoPools Product Specialist Lennox H.

Hi, Rob. This QC1072 motor is the correct replacement. However, I will need a clearer picture of the model number.

I’m trying to replace my K48K2PA101A1 Motor. What is everything I need to purchase?
 Reply

A  Answered on 2/12/2019 by InyoPools Product Specialist Hector F.

This is the correct replacement motor and in order to locate the correct seal kit you will need to know the model name or number of the front pump housing that the motor actually bolts to. If you do not know that information then you can always take a picture of it and email that image to upload@inyopools.com

?     Asked on 9/11/2018by Ron

I want to replace the bearings on my Century QC1072 (K48K2PA101A1); it's very noisy. Can you advise on the correct parts? I recently replaced the shaft seals however I suspect damage to the pump bearings occurred while the seals were leaking. Thank you!
 Reply

A  Answered on 9/12/2018 by InyoPools Product Specialist Lennox H.

Hi, Ron. The replacement bearing for the QC1072 motor will be the 6203RS. You will need two, one for the front and the other for the rear.

?     Asked on 6/28/2018by Bill LICHTENSTEIN

this seems to be the exact motor i need to replace my VERY noisy existing one, that feeds my pools solar system. I am in the construction biz & fairly handy, i this something I could easily tackle replacing? Is the electrical complicated ? Do I need to purchase any additional parts other than pump - like gaskets etc? Also I have NO room due to my existing pump being right up to a brick wall- will this slide out after bolts are removed ? Thanks for your help Bill
 Reply

A  Answered on 6/28/2018 by InyoPools Product Specialist Hector F.

Yes, it is recommended to replace the seals and gaskets so you will need to know the model name or number of the front pump housing that the motor bolts to. If you are unable to locate that then you can email us pictures to upload@inyopools.com so we can advise. Also being that the pump is close to the wall it is tough to confirm whether you will have enough room but the motors do slide away from the housing.

can I use this motor as an energy efficient direct replacement for Part # 5231X By A. O. Smith ? this is connected to a purex triton ultraflow pump, model 38448300. also is there any maintenance kit for this pump I should install when replacing the motor?
 Reply

A  Answered on 4/16/2018 by InyoPools Product Specialist Hector F.

The correct motor would be the part number 5231X and the seal kit for that pump is the part number GOKIT20.

I want to update the motor on sta-rite max-e-pro pentair water pool model: P6E6D-205L, from .75 hp to 1.5 hp. what side of motor should I get 48Y or 56Y??
 Reply

A  Answered on 9/8/2017 by InyoPools Product Specialist Lennox H.

Hi, Tan. Either motor frame can be used. First, you will need to find out if your system can handle a 1.5 hp pump. Then replace the motor, impeller, diffuser, and seals.

Yes, that will fit your Max-E-Glas but I can ensure it is the correct replacement if you have your part number from your motor.

?     Asked on 4/11/2017by Peter Snow

Hi The motor that you suggested to replace my A.O Smith 1 HP K48K2PA105C, is a (B2853) and is rated at 3/4 HP, the max load reads 12.6/6.3 and my K48K2PA105C is rated at 13.8/6.9. Losing 1/4 HP seems like it might have a hard time. I do have solar panels and I am concerned this might work this motor to much.
 Reply

A  Answered on 4/11/2017 by InyoPools Product Specialist Scott W.

With that particular energy efficient motor you will not be saving a whole lot, but the two motor are basically the same. Both have a total horsepower of 1.25 so putting out the same horsepower.

What shaft seal do I need? I'm replacing an A.O. Smith motor (QC1072) that is coupled to a WhisperFlo Model WFE-3. Thanks
 Reply

A  Answered on 6/30/2016 by InyoPools Product Specialist Alan M.

The correct shaft seal you would need is the PENTAIR SHAFT SEAL ASSEMBLY OEM (071734S) or the Generic Seal, Pump 1000 (psr 1000). The first is the manufacturer's version, the latter is the generic.

Hello Stan. The A.O. Smith 3/4 HP E.E. Square Flange Full Rate Motor is an exact replacement fit for the Sta-Rite Max-E-Pro 3/4 HP Full Rate Energy Efficient, Model P6E6D-205L. When replacing the motor, we strongly recommend replacing the Shaft Seal. If you would like to replace all your pump seals, we have the Tune Up Kit Sta-Rite Max-E-Pro available as well.

Why should I purchase a Tune Up Kit?
 Reply

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 1/12/2012by Guest

Why do I need to purchase a new shaft seal?
 Reply

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?
 Reply

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.

Old motor hummed on start up this spring

Written on 7/23/2020 by Guest

Hit the old motor capacitor with a hammer a couple times, then ordered an identical replacement motor.

Received in a good amount of time. Unhooked the old, connected the new, and checked my wiring, hit the power switch and, drat, it hummed and smoked. Power off, Contacted INYO support, they suggested a few things. But seriously, it turned fine via a screwdriver at the end of the motor... Well, took it all apart and put it back together again. I swear, same as before, but this time it powered on it started right up and purred nice and quiet. That was over 2 months ago. Still running nice and quiet. Thanks!

New motor was a exact fit so new install was very easy. Move pump housing and impeller to new motor, install new wiring and loom and make connections.
