Gear Oil Specifications

Oil Analysis
An oil analysis program is the best way to determine the
optimum oil change interval and the condition of the crawler
gearboxes.
Periodic Maintenance
Initial Operation
Drain and refill both crawler gearboxes after the first 200
hours of operation.
Monthly or Every 200 Hours
Check the oil level in both crawler gearboxes every 200
hours of operation or monthly, whichever occurs first, by
performing the following.
1. Travel the crawlers until the plugs are positioned as
shown.
2. Lockout-tagout the crane.
3. Thoroughly clean the area around the plugs to prevent
dirt from entering the gearboxes.
4. Remove the fill plug (1) and the level plug (2) from the
gearbox.
5. The oil must be up to the bottom of the level plug
opening.
6. If necessary, add the specified oil to the gearbox with a
funnel through the fill plug opening.
7. Install the fill and level plugs.
8. Repeat the procedure for the other crawler gearbox.
Every 6 Months or 1,000 Hours
Drain and refill both crawler gearboxes every 1,000 hours of
operation or every 6 months, whichever occurs first, unless
