6. KM PUMP MOTOR ASSEMBLY:
The KM pump assembly has a dual winding PSC motor with
an internal overload. The motor has a cast housing and
sealed stainless steel roller bearings. No lubrication is
required for these roller bearings.
If the pump motor fails, always repalce the pump motor
capacitor. If other failures occur, the front end of the pump
assembly is rebuildable. The mechanical seal is the most
common failure part and can be replaced.
Following, are the assembly breakdown’s for two generic
pump assemblies. Use these drawings as a guide to reas-
semble a pump assembly that you are rebuilding.
