How to Replace Pool Pump Bearings

Save

Your pool pump is almost like the heart of your swimming pool. It pumps water throughout the system, circulating the water through the filters to prevent dirt and debris from building up, as well as to keep algae from forming on the sides of the pool's walls. Inside the pump is a set of bearings that help the components of the motor run smoothly. When they become clogged with dirt and debris or wear down, your pool pump may get very noisy or stop working altogether.

Things You'll Need

  • Wrench
  • Ratchet set
  • Ball bearing puller
  • Turn off power to your pool pump by unplugging it from the power source or by turning off the circuit breaker.

  • Remove the plumbing from the pump. Take off the unions on the suction and discharge side using a wrench. Loosen the pool pump from the fitting holding it to the ground and move it to a comfortable area to work in.

  • Remove the housing from the pool pump and separate it from the motor. Look at the owner's manual for your pump to see the specifics on how to remove the pool pump housing, since each model is different. Usually you will need to loosen a bolt with a socket wrench and loosen the metal band that holds it in place.

  • Remove the four bolts that hold the pump together. These are located on the hand bell of the frame. Remove the motor end bells.

  • Pull out the motor armature to expose the ball bearings. Insert your ball bearing puller to pull out the old ball bearings. Inspect them for damage. Replace the old ball bearings with new ones after greasing them with bearing grease, and reassemble the pump.
