DRUM GEARBOX OIL CHANGE
Drum gearbox maintenance consists of periodically checking
the level and changing the oil in the gearboxes for drums 1,
2, 3, 4, 5, and 6.
Gear Oil Specifications
For gear oil specifications and gearbox capacities, see the
Lubrication Guide supplied with the crane.
Oil Analysis
An oil analysis program is the best way to determine the
optimum oil change interval and the condition of the drum
gearboxes.
Periodic Maintenance
See Figure 5-15 for the following procedure.
Initial Operation
Drain and refill the gearboxes after the first 200 hours of
operation.
Monthly or 200 Hours
Check the oil level in the drum gearboxes every 200 hours of
operation or monthly, whichever occurs first.
Fill each drum gearbox through the fill port (3) to the middle
of the sight gauge (5).
Every 6 Months or 1,000 Hours
Drain and refill the drum gearboxes every 1,000 hours of
operation or every 6 months, whichever occurs first, unless
an alternate interval has been established through an oil
analysis program.
Quick-Drain Valve
Each drum gearbox is equipped with a quick-drain valve that
requires use of the quick-drain drainer assembly (see
Figure 5-14
). The quick-drain drainer assembly is stored in
the parts box supplied with the crane.
