IMPELLER STACK REPLACEMENT
RISK OF ELECTRIC SHOCK. Can shock, burn or kill.
Capacitor voltage may be hazardous. To discharge capacitor,
hold insulated handle screwdriver by the handle and short
capacitor terminals together. Do not touch metal screwdriver
blade or capacitor terminals.
1.
Remove pump from service and mount vertically in vise (if
available), motor side down. See Figure 8. Clamp motor at

4.
Unscrew overload and set it aside. Do not disconnect
wires. Slide 7/16" open end wrench in behind spring loaded
centrifugal switch as shown. Place on motor shaft flats to
hold shaft stationary.
5.
With one 7/16" wrench in place on motor shaft, place second
wrench on shaft hex at pump end and unscrew impeller
stack by turning counter-clockwise.
Once loose from motor shaft, hold shaft by snap ring using a
pliers or similar tool, and pull stack from shell. You may have
to apply a back and forth motion to break stack loose from
shell.
To assemble with replacement impeller stack, keep pump in the
vertical position, motor down, and reverse Steps 1 through 5.
Assembly hints:
A.
Apply a soapy water solution to suction and discharge
O-rings to ease seating of shell.
B.
Make sure mechanical shaft seal spring is in proper
position on motor shaft.
