Hour Service Checks
Replace Axle Differential and Planetaries
Oil
NOTE:
Oil in both front and rear axles must be replaced after
first 500 hours of operation to comply with new
machine break-in requirements. After that, axle oil
check must be done every 500 hours of operation
and replacement must 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. Position wheels on
axle being drained so that axle end level plugs (1,
Figure 98) are in the lowest position. Apply parking
brake. Block wheels.
2. Clean areas around drain plugs on both ends of axle.
Remove plugs.
NOTE:
See “Fluid Capacities” on page 4-16 for
capacity and “Table of Recommended
Lubricants” on page 4-14 of this manual for
recommended oil for the operating conditions.
NOTE:
Dispose of drained fluids according to local
regulations.
3. Clean area around level plug (1, Figure 99) and drain
plug (2) on center differential. Remove level plug and
drain plug. Allow oil to drain into a suitable container.
4. Install drain plug Figure 99into center differential, and
tighten.
5. Pump oil into level plug hole on center differential. Add
oil until oil level is even with bottom of plug hole.
