REMOVAL AND REPLACEMENT: Gearmotor

To Remove and Repair the Gearmotor
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 4 cap screws holding the
gearmotor to the base of the machine.
3. Remove the gearmotor from the
icemaker.
Bench test the gearmotor, check for
oil leaks, noise, and amp draw.
To Inspect the gearmotor.
A) Remove the cap screws holding
the gearmotor case halves together
and pry the two cases apart.
B) To lift off the cover, lift up until you
can feel internal contact, then pull the
cover towards the output gear end,
and then lift the cover (with drive
motor attached) up and away from the
gear motor case.
Note: The gearcase cover, output
gear, bearings and output shaft are
a pressed together assembly.
Replace as a unit.
C) Inspect the oil, gears, and
bearings. If the oil level and condition
is acceptable, quickly check the gears
and bearings. They are likely to be
fine if the oil is.
If there is evidence of water in the oil
(rusty bearings and gears; the oil
having a creamy white appearance;
oil level too high) carefully inspect the
bearings and gears. If in doubt about the condition
of a part, replace it. The oil quantity is 14 fluid
ounces, do not overfill.
Electrical Shock Hazard.
Electrical shock can
cause personal injury.
Disconnect electrical
power before beginning.

D) After replacing parts as required,
(if any) reassemble the gearcase.
The two smaller gears and the oil
should be in the lower case, the
output gear will be with the cover. As
you lower the cover onto the lower
case, the cover will have to be
moved closer to the second gear
after the output gear has cleared the
second gear top bearing.
E) After the case is together, and the
locating pins are secure in both ends,
replace all cap screws.
