  • Turn the electricity back on and check that the pump is working.
  • Remove The Rear Bearing First

    Setup the bearing puller on the rear bearing. The “teeth” of the puller should be positioned on the outside ring of the bearing to clear the retainer clip on the back. It goes without saying that the center post of the bearing puller should be aligned with the motor shaft. Turn the nut on the bearing puller to work the bearing off of the shaft. Once the bearing is off, check the id/model number stamped into the back side of the bearing. make sure that this matches the new bearing that you have bought.

    Pool pumps should be run with enough water on the suction side. While some models are self-priming, there are others are primed manually.

The motor should be shut-off immediately to stop it from getting damaged further.

    The Flow Rate Of The Pool Pump Is Low

    How to Replace a Pool Pump Motor

    If the flow rate of the pump has dropped, you will want to make sure there is nothing blocking the flow of the pump or filter. Check your filter gauge first. If you are above 10psi over the clean reading specified by the manufacturer, youll want to clean the filter to reduce the pressure and reset the flow back to the pool pump.

    Next, check your pump basket and impeller for debris that would be blocking water flow. To remove the impeller, turn the power off to the pump and remove the screws in the middle of the pump body. Once the screws have been removed, pull the assembly out of the housing and remove the gasket away from the impeller, remove any debris and re-assemble.

    Certain factors can speed up your motors decline. If it is not properly ventilated, the motor may be more prone to overheating, which can damage the motor and the pump. Harsh weather, like hurricanes and floods, can damage your motor, in the event of a natural disaster, store your motor inside on a flat surface.

    Depending on its quality, pool pumps often last between 8 to 15 years. If the motor has been running for about ten years or more, it may be time to replace it.

    • Use a screwdriver to unscrew the cover of the back end of the motor. For safety, use insulated tools for wiring.
    • Feed the three wires through a conduit fitting and into the back of the motor.
    • Connect the power wires to the power terminal and connect the ground wire according to manufacturers instructions.
    • Replace the motor cover with a screwdriver and restore power at circuit breaker.

    Strange Soundscoming From The Motor

    Ifeverything looks like itâs in good shape with the overall pump, itâs time tomove onto the motor. Motors are fairly straightforward. Theyâre either runningor theyâre not. The best way to make sure your motor is in good shape is to useyour ears. Keep the pump housing open, so you can listen closely to whatâshappening with the motor. You might want to wait until some of the other soundsin your neighborhood settle down for the evening. When itâs quiet, listen forthe following sounds:

    Grinding

    Ifyou hear a loud grinding sound, itâs usually a sign that the bearings aregetting worn down. The bearings are the part of the machine that keep the motorrunning. Your pump could be leaking water, or the bearings might need to bereplaced instead of the entire motor.

    Screeching

    Screechingis also a sign that your motor bearings need to be replaced. These loud, oftenpainful sounds could also be a sign of rust or oxidation, making it moredifficult for the bearings to do their job.

    Humming

    Whenyour motor is accompanied by a strange humming sound, it usually means thecapacitor has failed. This component provides a charge so the motor will runconsistently. The most likely reason your capacitor has failed is a surchargeof electricity that causes the capacitor to overheat. You can replace thecapacitor instead of replacing the entire motor.

    Pops and Clicks

    No Sound at All

    Ifyour motor is completely silent, it probably means the motor is dead and itneeds to be replaced.

    Flow Rate Of The Pool Pump Is Low

    If the flow rate of the pump has dropped, you might want to make sure there is nothing blocking the flow of the pump or filter. This can be done by checking your filter gauge first. If you are above 10 psi over the clean reading specified by the manufacturer, you should clean the filter to reduce the pressure and reset the flow back to the pool pump.Next, check your pump basket and impeller for debris that would be blocking water flow. To remove the impeller, turn the power off to the pump and remove the screws in the middle of the pump body. Once the screws have been removed, pull the assembly out of the housing and remove the gasket away from the impeller, remove any debris and re-assemble.

    The Pool Pump Is Making A Humming Noise And Will Not Start

    If your pool pump will not start and you hear a humming noise, check you impeller for any debris. If debris starts to build, it can block the impeller and disable the pool pump.

Once the screws have been removed, pull the assembly out of the housing and remove the gasket away from the impeller, remove any debris and re-assemble.

    How To Replace The Bearings In A Pool Pump

    1.5HP InGround Swimming Pool Pump Motor w/ Strainer ...

    Pool pumps filter water with the use of a bladed impeller, which sucks the pool water in and passes it through a mesh filter or pump basket before sending it back into the pool. If the filter isn’t emptied regularly, over time the weight from built up debris cracks the filter. As water continues to flow through the pump, debris passes through the cracked filter and catches on the impeller blades, which clogs it. This forces the pump motor to work harder in an effort to move the clogged impeller, which in turn causes the pump motor to overheat. Pump motor bearings become damaged and need to be replaced when the pump overheats.

    1

    Turn off the power to the pool pump at the circuit breaker.

    2

    Disconnect the pump from the filter. Turn the discharge hose’s union collars counterclockwise to loosen them. Unscrew the intake and outflow PVC pipes or hoses to remove them.

    3

    Remove the rear pump housing that covers the wiring harness of the pump motor. Your pump may have four bolts holding the housing to the pump, or a metal band with a bolt that holds on the housing. Remove the bolts with a wrench. If they will not move easily, spray a little WD-40 or machine oil onto the threads. Wait five minutes to allow the oil to soak into the threaded part of the bolt, then unscrew the bolts and remove the pump motor housing.

    4

    5

    Remove the pump impeller. Twist the diffuser off of the pump motor.

    Does It Make Sense To Repair My Pool Pump Motor

    When it comes to a failed pool pump motor, the pool owner is faced with that eternal question, repair or replace?

    The first thing to check is if its still under warranty. For a pump that still has the original motor, you would contact the manufacturer of the entire pump. If you have already replaced the motor before, you would contact the manufacturer of the motor. As most pump and motor warranties are only 1 year, you might be out of luck but its worth double checking the purchase date.

    Assuming you are out of warranty, you have a decision to make. A replacement motor is generally going to cost you in the neighborhood of $150 $300 depending on the horsepower. Add another $15 $30 for the absolutely necessary, non-negotiable new shaft seal. Can you repair it instead for less? Probably. Is it worth it? Maybe.

    Heres the deal with repairing pool motors. You have to figure out the actual problem first. Is it the capacitor, the bearings, an electrical short? If youre mechanical and handy and know your way around a pool pump, then it could be fairly easy for you to diagnose the issue and even repair it yourself.

    If you are in the throes of the repair / replace debate and want one of our techs to chime in, please feel free to call us at 877-372-6038.
