Hoist Gearbox Oil Change
To change the hoist gearbox oil, rotate the drum so that the
plug is visible through the lower hole in the side plate (See
33, Figure 5-2, view 1). Screw in a piece of 1 inch pipe in the
gearbox oil drain to allow the oil to drain. Remove the
gearbox vent (30, Figure 5-2, view 1), then with a hex
wrench remove the drain plug located inside of the 1 inch
pipe (See Figure 5-2, view 2). Examine the used oil for signs
of significant metal deposits and then dispose of it in a proper
manner. Remove the 1 inch pipe.
Rotate the drum so that the port is visible through the
gearbox oil fill and level hole in the side plate (Figure 5-1).
Install a 1 inch pipe with elbow into the upper hole in the side
plate (See Figure 5-2, view 3). Fill the gearbox with
1.42 liters (1.50 quarts) of oil. Remove the pipe and elbow,
then replace the plug.
For information about changing hoist brake oil, see “Drain /
Add New Hoist Brake Oil” on page 5-8. See “Lubrication
Chart” on page 5-5 for recommended oil type and grade for
