POWER CORD REPLACEMENT
(1) Loosen the plastic compression nut that retains the
power cord. Slide nut out of the motor housing.
(2) Pull the power cord from the motor housing by hand.
The cord may need to be wiggled back and forth several
times to loosen from the housing. Pull the power cord
out until the connecting wires are fully exposed.
Disconnect the motor power and ground leads with a
pair of pliers.
(3) Reconnect the motor power leads and ground to the
new power cord. The ground terminal on the power
cord has a male connector, and the power terminals on
the new power cord are female.
(4) Carefully push the connected wires into the motor
housing until the molded body of the power cord seats.
Make sure that the wires stay away from the rotor and
shaft. Slide the nut into place and hand tighten.
Tighten the nut with 13/16” wrench until snug, but do not
over tighten.
(5) Plug pump into grounded receptacle to test operation.
Pump must run quiet, free of vibration, without tripping
out breaker.
MOTOR REPLACEMENT
(1) Disconnect the power cord and drain the oil as noted in
the previous sections. If the oil shows signs of water or
other contamination, it may be necessary to replace the
seal assembly as noted in a previous section.
(2) Loosen and remove the three cap screws retaining the
motor housing. Lift the motor housing off of the pump
assembly.
(3) Remove the O-ring from the remaining pump assembly.
Clean surface area and place new o-ring into position.
Be careful not to cut o-ring when installing.
(4) Position new motor housing (with new stator), onto the
pump assembly. Align the screw bosses, and insert the
three cap screws. Evenly tighten the cap screws.
(5) Reinstall the power cord as noted in the previous
section.
(6) Replace oil in the motor housing using only Myers
submersible transformer oil. The level should be 3/4”
below the top of the motor housing. Check with dip stick
to assure that the pump is properly filled.
(7) Plug pump into grounded receptacle to test operation.
Pump must run quiet, free of vibration, without tripping
out breaker.
