Service and Lubrication
The horizontal part of the oil gauge and drain line must be level or
slightly lower at the sight glass than it is at the Geareducer. The oil
capacity of Series 32 Geareducers is 9 gallons. The oil capacity of
the optional oil filter is one additional gallon. Connecting oil gauge
and drain lines require approximately one gallon of oil. Refer to
Table I
for suggested lubricants.
Fill the Geareducer and gauge and drain line system with oil, using
one of the following procedures:
Recommended procedure:
1. Pour oil through fill hole in Geareducer inspection cover until
it reaches height of “full” mark in the Geareducer case and at
the slight glass. See
Figures 2
and
4
. Reinstall pipe plug in
the fill hole.
2. Start fan drive. Run for one minute.
3. Stop the Geareducer. Allow ten minutes for oil level to stabilize
and recheck oil level at Geareducer.
4. If necessary, repeat steps 2 and 3 until stabilized oil level is at
the proper height.
5. Check placard location. “Full” mark on placard must be at same
elevation as “full” mark on Geareducer.
Alternate procedure:
If the cooling tower has an external oil gauge and drain line
equipped with three-way valve below sight glass the following
alternate procedure may be used:
1. Remove pipe plug. Turn valve control stem clockwise to open
drain. Collect used oil in an appropriate container.
2. With Geareducer drained, the three-way valve turned clockwise,
and the pipe plug removed, connect fill source, either a street
ell and stand pipe of sufficient length to extend above top of
the sight glass or a hose to a pump, to the three-way valve.
Pour oil through a funnel and stand pipe, or pump oil through
the hose. Check oil level occasionally by turning the valve control
stem counterclockwise and allowing the oil level in the sight
glass to stabilize. Continue filling until full level mark is reached.
3. With the oil level at the full mark turn the valve control stem
counterclockwise to close the drain and open the valve to the
sight glass. Remove the oil filling line and reinstall pipe plug in
the three-way valve.
Regardless of the procedure used, the Geareducer must be
filled to the full mark on the Geareducer.
Maintenance of the Geareducer should be scheduled as follows:
MONTHLY: Check oil level at least once a week using the fol-
lowing procedure:
Stop the Geareducer. Allow ten minutes for oil level to stabilize
and check oil level at sight glass. If needed, add oil to Geareducer.
If oil is added, repeat steps 2 and 3 of recommended procedure
until stabilized oil level is at the proper height.
SEMI-ANNUALLY: Change oil at least every 6 month or 3,000
hours of operation. Refer to recommended oil fill procedure. The
oil filter cartridge should be replaced at every oil change.
