When your neighbors start complaining about your screeching pump, it's a good sign that the bearings in your pool pump motor have failed and it's time to either replace the motor or replace the bearings in the motor. With the right tools, you can replace these bearings yourself. This guide is broken up into two parts. Part I shows you a step by step approach to removing the bearings of your pool pump motor. Part II shows you how to replace the bearings and reassemble the motor. Although this guide is specific to the Hayward Super Pump Motor, many steps are applicable to other brands of motors.
REVIEW TOOLS REQUIRED - This is a picture of most of the tools and parts you will need to replace the bearings of your pool pump's motor. From the left, they include: a socket wrench, a set of new motor bearings, the bearing puller, a short pipe, a set of shaft seal parts, and a hammer. You will also need a set of external ring pliers shown in step #29.
REVIEW PUMP - In this guide we will be removing the bearings of a Hayward Super Pump as shown here. The motor will have to be removed from the pump's housing before we start. See the first part of our guide on "How To Replace the Motor on Your Pool Pump" for instructions on removing this motor.
REPLACE MOTOR SHAFT SEAL - When your motor bearings fail, you should replace the shaft seal in your motor. As shown in this picture, the shaft seal is divided into two parts; one half goes on the impeller's shaft and one goes into the well of the seal plate. For more instruction on replacing the shaft seal, go to "How To Replace a Pool Motor Shaft Seal".
REMOVE V-SWITCH - On a Hayward Super Pump the motor's governor is attached to the end of the motor shaft and must be removed before the shaft and rotor can be removed from the motor shell. To access the governor, first remove the V-switch as shown. It is secured with a single screw. Push it aside. It does not have to be disconnected from its wires.
SET UP BEARING PULLER - Set up the bearing puller on the rear bearing as shown. The three teeth of the puller should be position of the outside race of the bearing to clear the clip ring on the backside of the bearing. The center post of the bearing puller should be positioned on the center of the motor shaft.
MOTOR DISASSEMBLY COMPLETE - This concludes the steps required to disassemble the motor and remove the motor bearing. For instructions on replacing the bearings and reassembling the motor see our guide on 'How To Replace the Bearings in a Pool Pump Motor - Part II.
