R&R-Gear Motor

To Check the Gear Motor:

1.Remove wires from terminals 1 and 2

2.Use an ohmeter to check for continuity. If there is none, replace only the motor. If there is continuity but the motor will not start, check the motor’s start switch.

3.Remove motor end bell or motor stator. With ohmeter wires attached to 1 and 2 move centrifugal switch actuator up and down to simulate motor rotation. If the ohmeter does not show any change, replace the switch or motor. If the ohmeter showns an open circuit, replace the switch or motor.

To Remove and Repair the Gear Motor Assembly:

(Assuming that the procedures through removal of the water seal have been performed)

1.Remove the electrical wires from the gear drive motor.

2.Unscrew the four (4) cap screws holding the gear motor to the base of the machine.

remove the gear motor from the machine.

Note: Bench test the gear motor, check for oil leaks, noise and amp draw.

To Inspect the Gear Motor:

1.Remove the cap screws holding the gear motor case halves together and pry the two cases apart.

2.To lift off the cover, lift up until you can feel internal contact, then pull the cover towards the output gear end, and lift up the cover (with drive motor attached) up and away from the gear motor case. Note: The gearcase cover, output bearings and output shaft are a pressed together assembly.

3.Inspect the oil gears and bearings. If there is evidence of water in the oil (rusty metal, too much oil, white oil) replace the oil and damaged parts.

4.The oil charge is 14 ounces. Do not overfill.

5.Reassemble and bench test the gear motor, check for oil leaks, noise and amp draw.
