This is Part II of a two part guide on replacing the bearings in a pool pump motor. The first part, "How To Replace the Bearings in a Pool Pump Motor - Part I" shows you a step by step approach to removing the bearings of your pool pump motor. This second part 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 referenced in step #5. The bearing puller shown here is not needed in this part of the guide.
PRESS ON FRONT BEADING - Stand the shaft and rotor up on the back end of the shaft and line up the bearing over the top of the shaft. Gently tap the middle of the bearing onto the shaft to get it started. Then take a 1/2" pipe and tap the bearing down to the retainer clip. The pipe should only contact the inner race of the bearing. If the pipe is too large in diameter, it may push on the other race of the bearing and damage the bearing.
VIEW BEARING LOCKING CLIP - The front bearing is held into the bearing well of the front end bell by a locking clip. When the locking clip is rotated clockwise, as shown in picture A, the bearing will pass the clip. When it is rotated counter-clockwise, as shown in picture B, the edge of the clip is positioned inside the well edge to lock the bearing into the well. Screw the locking clip loosely and position the clip to clear the well edge, like Picture A.
SECURE V-SWITCH - Reattach the V-switch with the single screw. If your motor is produced before November 2001, this V-switch may have to be adjusted for optimum operation. See our guide on "How To Adjust the V-Switch on a Hayward Super Pump Motor". After Noverber 2001, the A.O Smith motors were produced with a no-adjust switch.
REPLACE MOTOR SHAFT SEAL - When your motor bearings fail, you should replace the shaft seal in your motor. If you didn't replace the shaft seal in Part I, do it here. For more instruction on replacing the shaft seal, go to "How To Replace a Pool Motor Shaft Seal".
REPLACE DIFFUSER GASKET - Pull off the diffuser gasket and replace it with a new one from your GOKIT. Lubricate the gasket slightly,
REPLACE HOUSING GASKET - Replace and lubricate the housing gasket located at the joining end of the pump housing
REPLACE MOTOR BOLTS - Replace the four bolts evenly. If bolts were numbered 1 through 4, replace bolts in this sequence - 1, 3, 2, 4 - to ensure that the motor is set properly inside the housing. Loosely tighten bolts in this sequence, then go back and tighten them down again in this sequence. If pump has 6 bolts, replace bolts in this sequence - 1, 3, 5, 2, 4, 6.
CHECK MOTOR - This completes the re-assembly of the motor and pump. To check that everything went together correctly and that the new bearings are lined up correctly, change the pump power configuration to 115V, attach a power cord and plug the pump in a 115V bench wall socket for a few seconds to hear if the motor is running smoothly. Remember to change the pump's power back to 220V if your pump normally operates at 220V. For additional information on wiring this motor, see our guide on "How To Wire A Pool Pump".
