Pool Pump Motor BearingsDescription: Is your pump sounding unhealthy? Probably a bearing. Within your pump's motor, there exists a front bearing and a rear bearing. Bearings are sealed to guarantee ideal operation, so they cannot be re packed or re lubricated and must be replaced. They are swapped out when they start to produce a sound like a scream or screech. Bearings may sustain damage if the pump operates without lubrication, overheats, or experiences high pressure loads.
