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 gear motor, check for oil leaks,
noise, and amp draw.
use the access valves at the front of the unit for
weighing in the charge. All liquid refrigerant must
be weighed into the receiver through the "front
seated" king valve".
