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