8. Label, disconnect and cap the outrigger hydraulic
hoses (6). Cap all fittings to keep dirt and debris from
entering the hydraulic system.
9. Support the outrigger assembly using a suitable
jack, hoist or overhead crane.
10. Remove the capscrews, hex nuts, flat washers and
mount plates (7).
Note: Record the number and thickness of shims to
ensure correct installation.
11. Remove the outrigger assembly using a suitable
jack, hoist or overhead crane. Remove the shims (8)
from the pivot pin.
12. Move the outrigger assembly away from the machine
and carefully lower it to the ground. Block up or
support the assembly so that it does not move or fall.
13. Inspect the pivot bearing (9). Replace the bearing if
worn or damaged.
b. Outrigger Installation
1. Using a suitable jack, hoist or overhead crane and
sling, remove the outrigger assembly from its
supports. Balance the assembly and prevent it from
tipping, turning or falling while positioning it on the
machine. DO NOT raise or otherwise disturb the
machine while installing the outrigger assembly.
Keep the assembly supported and balanced during
the installation procedure.
2. Place the same number and thickness of shims (8)
on the pivot pin, as recorded during removal.
3. Position the outrigger assembly onto the machine,
aligning the hole in the assembly on the axle pivot
pin and the mounting plate under the axle flanges.
4. Install the two mount plates (7) onto the top of the
axle and secure with the previously used hardware.
Note: ALWAYS use new o-rings when servicing the
machine.
5. Install new o-rings into the fittings. Lubricate the o-
rings with clean hydraulic oil.
6. Uncap and connect the previously labeled hydraulic
hoses (6) to their appropriate locations.
7. Tie the strings left in the outrigger housing during
removal to each pressure switch wiring connector,
and pull the harness through the outrigger housing.
8. Connect the wiring connectors to the outrigger
cylinder pressure switches. Secure the harnesses to
the cylinders with wire ties.
9. Check the hydraulic reservoir oil level.
10. Properly connect the battery.
11. Remove the Do Not Operate Tags from both the
ignition key switch and the steering wheel.
12. Start the engine. Turn the steering wheel several
times lock to lock, operate the frame tilt function
several times in both directions and check the
function of the brakes. Check for hydraulic leaks,
and tighten or repair as necessary.
c. 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 the stabilizer
solenoids and other 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.
