6.3 GREASING
CHECKING THE GEARBOX OIL LEVEL
Check the gearbox oil level daily (Figure 46). Check more
frequently if leaks exist around any of the plugs or shaft
seals.
The oil level in the gearbox should be no higher than the
bottom of the driveshaft.
CHANGING THE GEARBOX OIL
Each gearbox is equipped with a drain plug and a check/
fi
ll plug. Every 500 operating hours or annually, whichever
comes
fi
rst, the oil should be replaced. When changing the
oil, follow this procedure:
1. Place a container under the gearbox.
2. Remove the drain plug. Allow 10 minutes to drain.
Always clean the vent plug if any leaks are noticed
around shaft seals.
