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 ohnmeter wires attached to 1 and 2 move
centrifugal switch actuator up and down to simulate motor rotation. If the ohnmeter 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 Case Assembly:
1. The oil charge is 14 ounces. Do not
overfill.
2. There are no serviceable parts
in the
gearcase assembly. If the gears or
bearings are damaged the entire
gearcase assembly will require
replacement.
