    Pentair motor replacement

    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.

    [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!

    Re: Pentair motor replacement

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

    They have basic timer, intermatic t101p201

    Re: Pentair motor replacement

    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

    Re: Pentair motor replacement

    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.
