You are trying to remove the pump so you can replace the impeller correct?
To remove the impeller you do not need to remove the whole pump. Turn off the electric first. Then just remove the several bolts and separate the back half from the front. Then disconnect the electrical from the motor and your can pull the motor with the seal plate, and impeller all the way out and work on it. To remove the impeller you need to lock the motor and unscrew impeller. Depending on the motor, you remove a cap in the middle of the tailpiece and hold with a wrench, or remove a cap that covers the whole end and grab the shaft with a wrench (usually 7/16") by sliding it under one of the components (not sure exact part off top of my head have to look at it) and then turning impeller. If the impeller has a bolt or screw in the middle remove that first. It should be reverse thread so make sure you don't turn the wrong way and break or strip. If there is no screw, or after you've removed it, just spin the impeller off (it should be counter clockwise standard thread). If you can't do it by hand and assuming you don't have an impeller wrench, be very careful and use a large pliers, pipe wrench, or strap wrench to loosen it. After that you unbolt the motor from the seal plate, pull the seal plate away from motor (this removes half the seal), and then pop the other half of the seal from the seal plate. Make sure replace the shaft seal, and use a tiny bit of pool lube on the rubber parts when installing, but keep the white and black ceramic surfaces 100% free of any dirt, grease, etc while working with them

Brand new motor replaced old pb4. After installation it just hums and does not pump. Before installation it works fine without water going through? Any body know what is wrong?


Double check the wiring installation. One wire wrong will stop it. Don't let it hum! Compare old motor to new, are they the same voltage? Can you rotate the motor by hand? It should be free.

Just bought a new polaris booster pump (PB4-60) and installed it...the polaris ran for a few seconds and shut off.


Have you checked for voltage at the pump motor? Did you wire it correctly? Is the motor 110V or 220V. Did you match the motor to your existing voltage?

My polaris booster pump will not come on. when i turn it on the motor makes a humming noise but wont start


Does it have a century motor? If so, remove the shaft cover plate at the rear and try rotating the shaft with a very thick slotted screwdriver or substitute until it turns fairly easily. Often some mild oxide develops around components that just needs to be disturbed.
