Changing Geareducer Oil

Drain the Geareducer oil by removing the drain plug. See

Figure 2

for location. If equipped with an external dipstick/oil

level gauge, remove the drain plug at that location, and drain the
entire system.
When using synthetic oil with extended service intervals remove a
sample for lab analysis and look for evidence of foreign material,
such as water, metal shavings or sludge. If you find unacceptable
condensation or sludge, flush the Geareducer with mineral oil
before refilling.
The horizontal part of the oil line must be level or slightly lower at
the oil level gauge than at the Geareducer. The oil capacity of the

32.2 Series Geareducer: 9 gallons (

34 liters)

The oil level gauge line requires approximately one additional
gallon of oil. Refer to back cover for suggested lubricants. If the
Geareducer is equipped with an external dipstick/oil level gauge
an additional 3 to 4 quarts of oil will be required. Be certain that
the vent on the Geareducer (and external dipstick/oil level gauge,
if present) is not plugged. Verify that the gauge/drain line is full
and that there aren’t any leaks at the connections.

operation and service

Fill the Geareducer and oil line system with oil, using one of the
following procedures:
Recommended procedure:
1. Install oil at the opening at the Geareducer inspection cover.

Full is the center of the sight glass. If oil is

not

visable in the

sight glass then oil needs to be added . See

Figures 3

and

Install plug.

2. Start the fan drive and run for one minute.
3. Stop the fan drive. Allow ten minutes for oil level to stabilize

and recheck oil level at the Geareducer.

4. If necessary, repeat steps 2 and 3 until stabilized oil level is at

the proper level.

5. Check gauge placard location. Full mark on the placard must

be at the same elevation as the Full mark at the Geareducer.

Alternate procedure:
The cooling tower has an external oil gauge and drain line equipped
with a three-way valve below the oil level gauge. See

Figure 3

1. Remove pipe plug. Turn valve control stem clockwise to open

drain.

2. With Geareducer drained, the three-way valve turned clockwise,

and the pipe plug removed, connect fill source (usually a hose
to a pump, to the three-way valve).

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.
