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 gearmotor plate.
3. Remove the gearmotor from the
icemaker.
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 case cover output gear,
bearings, and shaft are one 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.
Note: The gears and bearings are
available only as pressed together
sets.

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, 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.
4. Bench test the gearmotor, check for oil leaks,
noise, and amp draw.
