Repair Procedures: The gear reducer
(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 gear
reducer to the ice machine.
3. Remove the gear reducer from the icemaker.
To Inspect the gear reducer.
1. Remove the cap screws holding the gear
reducer 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 then lift the cover (with drive
motor attached) up and away from the gear
reducer case.
Note: The case cover output gear, bearings, and
shaft are one pressed together assembly. Replace
as a unit.
3. 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.
4. After replacing parts as required, (if any)
reassemble the gear case and cover. 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.
5. After the case is together, and the locating pins
are secure in both ends, replace all cap screws.
6. Bench test the gear reducer, check for oil leaks,
noise, and amp draw.
