Figure 5 Oil Level Gauge Assembly
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
until it reaches the level of the Full mark on the Geareducer
case and at the oil level gauge. See Figures 4 and 5. 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 4.
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.
