5.4 AXLE REPLACEMENT
5.4.1 Axle Removal
The front and rear axle assemblies differ in that the front
axle assembly is equipped with a parking brake
mechanism and a limited slip feature; the rear axle has
neither. The following steps outline a typical axle removal
procedure, suitable for either the front or the rear axle
assembly.
Cleanliness is extremely important. Before attempting to
remove the axle, thoroughly clean the machine. Avoid
spraying water or cleaning solution on electrical
components. If using a steam cleaner, seal all openings
before steam cleaning.
Note: Clear the work area of all debris, unnecessary
personnel, etc. Allow sufficient space to raise the
machine and to remove the axle.
1. Park the machine on a firm, level surface, level the
machine, fully retract the boom, lower the boom,
place the travel select lever in the (N) NEUTRAL
position, engage the parking brake, straighten all
wheels and shut the engine OFF.
2. Place a Do Not Operate Tag on both the ignition key
switch and steering wheel.
3. Open the engine cover. Allow the system fluids to
cool.
4. Properly disconnect the battery.
5. Remove the bolts securing the fender assembly to
the axle.
WARNING
DO NOT service the machine without following all
safety precautions as outlined in the “Safety Practices”
section of this manual.
WARNING
An improperly supported machine can fall. Safely
raise and adequately support the machine so that it
will remain stable and in place before attempting to
remove an axle.
