Replacing Bearings In Your Pool Pump

Pool pumps filter the pool water using a bladed impeller. It is responsible for sucking the pool water in and passes it through a mesh filter or a pump basket. If the filter still has debris in them, over time, the weight will get built up and eventually destroying the filter.

As water continues to flow in the pump, debris will pass through the cracked filter and catches on the bladed impeller. It will end up clogging it and forces the pump motor to work double-time to move the clogged impeller. As a result, pump motor bearings become damaged and need to be replaced when the pump overheats.

Here’s how to replace the bearings of your pool pump:

  1. Make sure that the power of the pool is off at the circuit breaker.

  2. Disconnect your pool pump from the filter. Then turn the discharge hose’s union collars in counterclockwise to loosen them. Once it is loose, you can unscrew the intake and outflow PVC pipes or hoses to remove them.

  3. Next, remove the rear pump housing that covers all the wiring harness of the motor. Depending on the pump, it will show you four bolts that hold the housing to the pump. It can also be a metal band with a bolt that holds the housing and then remove the bolts using a wrench. If they are still not loose, spray a little WD-40 or any kind of machine oil to the threads. Wait for a short period to allow the oil to properly soak and then unscrew the bolts and remove the pump motor housing.

  4. Once the housing is out, remove the bolts that connect the motor housing to the pump. You can find it easily because it is where the pump motor is sitting. Then pull the pump motor out of the housing.

  5. Remove the pump impeller and twist the diffuser off the pump motor. Afterward, remove the bolt that holds the two halves of the pump motor together.

  6. You can see both the back and front ends of the pump that is bell-shaped, then pull it off. If they do not remove easily, you can try to insert a flathead screwdriver into the seam and tap it using a happier to pop it off.

  7. Next is to place the pool pump bearing puller jaws at the back of the wheel-shaped bearing. It will sit on a drive shaft, and the pool pump motor will turn it. On the jacking screw, turn the center nut to pull the bearing off the shaft. Then remove the other motor bearing using the bearing puller in the same method.

  8. Onto the shaft put the new bearing, and drive it with a bearing tamping tool. It is a pipe that fits over the shaft to evenly disperse all the pressure and moves the bearing without damaging it. Then proceed to install the other bearing the same way.

  9. Reinstall the diffuser and the impeller after installing the bearings. Reinstall the front and the bell-shaped back end. Then you can proceed to reattach the pump to the hoses connected to the pool. Finally, turn on the motor to see if it runs smoothly and silently.


Overall, pool owners who upgrade their pool pumps and accessories will surely have to pay some money. But considering the new generation of pool pumps today, they are more energy-efficient and have the advanced state of the art technology.

They are most likely to save you more money in the long run. Reparations are only recommended when the cost of the repair is way below the total cost of acquisition. The integrity and the reliability of these serious reparations are more likely to bring additional costs as expected.
