" nuts from the motor studs and pulling the
pump end off the motor.
2. Remove the two motor lead plug screws from the top of the motor and pull the
motor lead plug from the motor by rocking the plug side to side while pulling.
Installing the New Motor Lead
1. Make sure the motor lead socket in the motor is clean and free of debris and
moisture.
2. Remove the baggie from the new motor lead plug and firmly slide it into
position in the motor lead socket.
3. Tighten the motor lead plug screws evenly from side to side until firmly
bottomed with the motor lead plug, flush with the top of the motor as shown
below. A 0mm to 1mm gap between the center of the motor lead plug and
the top of the motor is acceptable as shown.

Reattaching Pump End to Motor
1. Fit the pump end to the motor making sure the motor lead aligns with the recess
in the pump inlet and the motor studs align with the holes in the bottom of the
pump inlet.
2. The pump should drop right into place flush with the top of the motor. If it does
not, lift the pump end back up and slightly rotate the motor shaft, as the shaft is
most likely not aligned with the pump end shaft coupling and stopping the pump
from dropping into position. In addition gently rocking the pump back and forth
may aid in getting it to drop into position also.
3. Put the four 1

pressure. The nuts should be torqued to 13 ft. lbs.
4. Reattach the cable guard to the pump end.
The pump is now ready for operation.
