SERVICE AND REPAIR INSTRUCTION
DISASSEMBLY: Impeller and shaft seal can be inspected and serviced from lower end of pump by removal of 4 cap-
screws securing base plate, strainer screen, and suction cover. Screwdriver slot is provided in end of motor shaft to turn shaft
while holding impeller for removal. This permits removal of impeller without
disassembly of upper motor housing to hold motor shaft. Alternately, there is a shaft extension with two ats on the rear of the
motor for use when the impeller is difcult to remove. The upper motor cover must be removed to expose this shaft extension.
To service motor remove 4 hex nuts and bump top cover free from housing tube. Raise sufciently to disconnect power
cable connections. Slide housing tube up from pump casing and motor will be exposed for service or removal.
When servicing the and replacing the impeller or suction cover follow these instructions:The impeller has been revised to
typically require 1 shim (previously 7). The suction cover has been revised to require 1 gasket.
IMPORTANT: Make certain that wire leads are installed per diagram below.
Install top cover as indicated by arrow and instruction on top of cover. Make sure wires do not contact motor shaft when
installing motor cover.
