tighten. Check that the
impeller turns freely.
10. Replace oil in the motor
housing using only Hydromatic
submersible transformer oil.
The level should be 3/4" below
the top of the motor housing.
Check with dipstick to assure
that the pump is properly filled.
11.Plug pump into grounded
receptacle to test operation.
Pump must run quiet and free
of vibration.
Power Cord Replacement:
1. Loosen the 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 1"
wrench until snug, but do not
overtighten.

2. Loosen and remove the three
cap screws retaining the motor
housing. Lift the motor housing
off the pump assembly.
3. Remove the O-ring from the
remaining pump assembly.
Clean surface area and place

(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.
