Replacement Motor (Square Flange)
The internal ball bearings have reached a state of mechanical failure characterized by spalling or galling of the races. Once the bearings become audible, the friction has generated enough heat to likely compromise the motor's internal windings. Replacing the motor assembly is the standard resolution for restoring the structural integrity of the drive system.

Mechanical Shaft Seal
This is the primary root cause component. The failure of the carbon/ceramic seal faces allowed chlorinated water to migrate into the motor housing, causing the bearing corrosion that produced the noise. A new motor installed without a new shaft seal will likely experience bearing failure within months due to continued fluid ingress.

Seal Plate O-Ring / Gasket Kit (Go-Kit 32)
This kit provides the necessary elastomeric seals to ensure a vacuum-tight environment within the pump volute. Replacing these during a motor/bearing service prevents air leaks (cavitation) which can cause uneven shaft loading and premature bearing wear.
