Hoist Gearbox Oil
Hoist Gearbox Oil Change
Gearbox oil is drained by first removing the drain plug (33,
Figure 11-2) by rotating the drum so that the plug is visible
through the lower hole in the side plate (See view 1). Screw
in a piece of 1 in pipe to allow the oil to drain, and then with a
hex wrench remove the drain plug located inside of the 1 in
pipe (See view 2). Examine the used oil for signs of
significant metal deposits and then dispose of it in a proper
manner. Remove the 1 in pipe.
Rotate the drum so that the port is visible through the upper
hole in the side plate. Install a 1 in pipe with elbow into the
upper hole in the side plate (See view 3). Fill the gearbox
with 1.42 liters (1.50 quarts) of EP-90 oil. Remove the pipe
and elbow, then replace the plug (33).
