I am in search of a replacement motor for my sta rite max e glas pool pump. K48K2PA105C1 3/4HP 48Y frame Will this motor fit my pump? Exact Fit? Thanks! Victor

Hi, Victor. The Century QC1072 motor is the correct replacement motor, not the UQC1072.

i'm looking to replace my magnetek centurion part #168451, will this motor be an acceptable replacement? Also what would be the difference or advantage of this motor vs the usq1072?

A     Answered on 6/17/2016 by Scott W.

All three of those motors have the same total horsepower, the difference is going to be the amount of amps being used. The energy efficient motor is going to use about 25-30% less amps while putting out the same amount of horsepower.

does this work on Hayward super pump?

A     Answered on 8/28/2015 by Matt S.

The UQC1072 is not compatible with the Hayward Super Pump as this motor is a square flange, and the Super Pump uses a round flange motor. The round flange equivalent to the UQC1072 is the UCT1072 A.O. Smith 3/4 HP Energy Efficient Motor

Why should I purchase a Tune Up Kit?

A     Answered on 1/12/2012 by 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.

Why do I need to purchase a new shaft seal?

A     Answered on 1/12/2012 by 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 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)  Perfect Replacement

from Homosassa, FL ()

Pros: Perfect fit for old motor

Cons: Removing old impeller - no way to grasp motor shaft

I paid a little more to get a more efficient motor. Ordered on a Saturday & delivered Tues. After some difficulty in removing the impeller from the shaft of the old motor (there is no good way to grasp the motor shaft and I gingerly used a pipe wrench to dislodge the impeller), installation was a snap following the instructions available on INYO's web site. I recommend purchasing the GO-KIT tune up package as the shaft seal showed wear after 8 years & the gaskets tend to dry out and stretch. The new motor was up and running quietly in about 2 hours start to finish.

from Poway, CA ()

Pros: quiet, saves elelctricity

Cons: concerns about durabiity

I purchased the Energy Efficient 3/4 HP pump motor which installed just fine, and it runs fine, however the motor draws 5.5a. on my pump which is above its 4.8a rating. The motor I replaced was a standard motor and drew 6.9a. which was within the rating. While this motor is saving electricity, I am concerned about the durability of the new motor. I think that it should not have been rated as a replacement for the 3.4 HP StaRite Max-E-Glas II pump.

 (4 out of 5 stars)  Good pump

from Rockledge, FL ()

Pros: Good solid motor.

Cons: Instructions not included, electrical connections are difficult due to small space.

Your standard pump motor. Only had this pump for a short while but seems to be working well. Did not come with instructions; a little tricky to install, especially the electrical connection conduit. And not much room to make the wire connections since the terminals are immediately inside the opening. Also, these motors are heavy; it would be helpful to have a second person for installation. But this is a good pump for everyday swimming pool use. Seems well built.
