Maintenance
7. Place a cardboard washer over the seal face to
protect it and use a tube to push the stationary seal
half into the seal plate until it seats (Figure 4C). Be
sure you don't scratch or mar the polished face of
the seal. Also, keep your hands away from the seal
face to keep dirt and grease off of it.
8. Use the cardboard washer and tube to push the
rotating half of the seal into the new impeller,
polished face out (Figure 4D). Be sure you don't
scratch or mar the polished face of the seal. Also,
keep your hands away from the seal face to keep dirt
and grease off of it.
9. CAREFULLY slide the seal plate back onto the motor
shaft, making sure that you don't chip or scratch the
seal face in the process.
10. Thread the new impeller onto the motor shaft,
making sure that you don't chip or scratch the seal
face in the process.
11. Reinstall the motor shaft in the motor.
12. Install the new square-cut O-ring on the seal plate.
13. Bring the impeller/motor assembly up to the pump
body and insert the impeller and seal plate into the
pump body.
14. Install the 4 body screws (be sure to reinstall
the handle on the upper screws) and tighten
them securely.
15. Replace the motor brushes (see Brush
Changing Procedure).
Cord Replacement
Risk of electric shock . Can shock, burn
or kill. Unplug pump before working on or servicing
pump. Don't attempt to modify the cord or plug; these
instructions are ONLY for replacement of cord.
1. Unplug the pump.
2. Unscrew the two screws holding the cord plate to
the back of the motor. Pull the cord gently out of the
motor cavity.
3. Cut the existing wires on the motor side of the
crimps, as close to the connectors as possible (in
other words, leave yourself as much wire in the
motor as possible).
4. Strip all the wires back about 5/8" from the
wire ends.
NOTICE Make connections with wire nuts designed
for connecting 2 #16 AWG wires (see the wire
nut package).
5. Connect the green (ground) wire from the cord to
the green (ground) wire from the motor. Connect
the black (hot) wire from the cord to either black
wire from the motor. Connect the white (neutral)
wire from the cord to the remaining black wire from
the motor.
6. After you have made the connections, check all
connections carefully to be sure that no bare copper
shows. If you see any bare wire, disconnect the wire
nut and remake that connection.
7. Once you are sure that there is no exposed wire,
carefully stuff the wire and wire nuts back into the
cavity in the motor.
8. Hold the cord plate up against the motor and
reinstall the screws. Tighten thoroughly but do
not overtighten!
9. Once assembly is complete, SET THE PUMP DOWN
(that is, don't touch it) and plug it in (very briefly,
to avoid damaging the shaft seal) to make sure
that everything is correctly connected and nothing
is shorted.
10. The pump is ready for operation.

Motor Brush Replacement

2. See Brush Changing Procedure and unscrew brush
caps to remove brushes.

careful not to stretch springs. If reusing same
brushes, mark brush and brush cap for replacement
