AXLE DIFFERENTIAL AND PLANETARIES OIL REPLACEMENT
NOTE: Oil in both front and rear axles must be replaced after first 250 hours of operation to
comply with new machine break-in requirements. After that, axle oil check should be done
every 250 hours of operation and replacement should be done every 1,500 hours.
Each axle contains a center differential, and a planetary on each end. The same oil lubricates the center
differential and planetaries. These sections of the axle are connected, but the oil flows very slowly between
them. When checked, oil must be checked and refilled at the level/fill plug on the differential housing.
To drain and replace oil in an axle, perform the
following steps:
1. Drive machine onto a level surface. Apply
parking brake. Block wheels.
2. Clean areas around drain plugs on both
ends of axle. Remove plugs and allow oil
to drain into a suitable container.
NOTE: See “Fluid Capacities” on
page 4-5 for capacity and
“Table of Recommended
Lubricants” on page 4-3.
NOTE: Dispose of drained fluids
according to local regulations.
