Repair Procedures: The Gear Reducer

Note: The high speed non-metallic fiber gear is the
only internal part that is a service part and can be
replaced individually. If any other parts of the gear
reducer are damaged or it is discovered that water
has infiltrated the gear reducer, the entire assembly
will need to be replaced.
1. Remove the electrical wires from the gear drive
motor.
2. Unscrew the 4 1/2" hex head cap screws holding
the evaporator adapter to the gear reducer.
3. Remove the gear reducer from the ice machine. It
is recommended to support the evaporator assembly
to ensure no damage to refrigerant lines.
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.
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.
4. After inspecting gear reducer and replacing high
speed non-metallic fiber gear if required, reassemble
the gear case and cover.

5. After the gear case is together, replace all cap
screws.
6. Check oil level. Remove red vented plug from
gearbox. Using a flathead screwdriver, check the oil
level using the vent hole between the motor and the
freezer. About 3/8" of oil should be on the tip of the
screwdriver blade. Any more and there may be water
in the gear case, any less and it may be low. The
correct oil charge is 14 ounces.
7. Bench test the gear reducer, check for oil leaks,
noise, and amp draw.
