Pentair motor replacement

PHXAZ · Jul 28, 2012

My neighbors' pump motor was making a grinding noise and when I turned it on it started smoking.

Since I have turned out to the neighborhood pool guy, I'll be replacing it for then.

Details -

Pentair
Part 7 - 177475-20
FR - Y56Y
Type - CX

Please suggest a replacement motor, where I can buy it and any tips/tricks for installation.

Thxs

[rul=http://www.troublefreepool.com/pentair-whisperflow-seal-replacement-how-to-w-photos-t10763.html]This topic[/url] covers the disassembly/reassembly process quite well. You won't need to replace all of the seals they did, but you will need to do the shaft seal and impeller removal/reattaching.

I believe that is the full rated 1 HP correct? The E-Plus Centurion B2982 is a new high efficiency two speed motor that should work pretty well plus it gives the pool owner the option of low speed to save energy.

Thanks for the quick reply

I have watched youtube vidoes of the shaft seal and impeller remove/replacement. That link is very helpful as well.

I like the suggestion on the pump, but would you have a single speed that you recommend? They are looking to spend as little as possible.

Hence me being the repairman!

If they go with the duel speed, is there anything else i need to do with the setup?

They have basic timer, intermatic t101p201

A two speed timer would be useful although you could wire a manual switch. The T104 + T106 is the most common but you can also add just the two speed timer portion (T106):

thxs, sounds like the single speed will be easier for me to install

Have you taken the pump off to see how the motor runs by itself. Maybe the bearing is just seized up not allowing the motor to turn. I would take it apart and take it to a local electric motor shop and ask them to look at it. That's what I did with my last one and sure enough it was burnt up but there has been other times when a simple repair can be made. For how much new motors cost I would at least look into it.
