AXLE DIFFERENTIAL AND PLANETARIES OIL REPLACEMENT
NOTE:
Oil in both front and rear axle 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 1500 hours.
Each axle contains a center differential, and a planetary in each end. The same oil lubricates center
differential and planetaries in axle ends, but oil flows very slowly between these points. When checked, oil
must be checked and refilled at all three places at the same time. 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 are in the lowest
position. Apply parking brake. Block
wheels.
2.
Clean area around level plugs on both
ends of axle. Remove plugs.
NOTE:
See “Fluid Capacities” on
page 4-5 for capacity.
CAUTION!
Never remove air cleaner element while engine is running. This will allow dirt to be sucked into
engine and cause serious engine damage. Always turn engine "OFF" before servicing air
cleaner.
