Removal And Replacement: Gear Motor - Ice-O-Matic GEM1856 Service And Installation Manual

GEM Models A/W
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 ohmmeter 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 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.
