removing it from beneath the machine. Place the
axle on a suitable support or holding stand.
d. Axle Installation
1. Before proceeding, ensure that the machine will
remain in place during axle installation. Block the
front and rear of both tires on the axle that is already
installed on the machine.
2. If applicable, raise the machine using a suitable jack
or hoist. Place suitable supports beneath the frame
and lower the machine onto the supports, allowing
enough room for axle installation. Ensure that the
machine will remain in place during axle installation.
3. Using a suitable jack, hoist or overhead crane and
sling, remove the axle from its support or holding
stand. Balance the axle and prevent it from tipping,
turning or falling while positioning it beneath the
machine. DO NOT raise or otherwise disturb the
machine while installing the axle. Keep the axle
supported and balanced on the jack, hoist or
overhead crane and sling throughout the installation
procedure.
4. Position the axle under the frame, and align the pivot
pin bearings with the holes in the frame.
5. Coat the axle pivot pin (3) with a light film of clean
engine or hydraulic oil; DO NOT use an anti-seize
compound.
6. Install the axle pivot pin and shims (4). Add or
remove shims until a maximum gap of 0.6 in
(1.5 mm) is obtained. Balance the number and
thickness of shims equally of both sides. Secure the
pivot pin with one capscrew and a new locknut.
Note: If new frame sway (front) or stabilizer (rear)
cylinder bearings (5) have been installed in the axles or
machine frame, the fracture in the bearing race must be
positioned at the 9 o’clock position as shown below.
7. Move the cylinder into position on the axle cylinder
anchor. Insert a cylinder-mount pin (2) through the
cylinder and cylinder anchor. Secure the cylinder-
mount pin with one capscrew and new locknut.
8. Apply multi-purpose grease through the self-tapping
lube fitting to lubricate the self-align bearing and the
cylinder-mount pin.
9. Install the drive shaft assemblies. Refer to Section
5.6.5, “Drive Shaft Installation.”
10. If reinstalling an axle previously removed from the
machine, position the driveshaft yoke on the axle
according to the alignment marks made earlier. If
installing a new axle, note the position of the
driveshaft yoke at the transmission. Align the
driveshaft yoke on the axle in the same plane as the
yoke on the transmission.
11. Install the wheel and tire assemblies. Refer to
Section 5.7.2, “Installing Wheel and Tire Assembly
onto Machine.”
12. Carefully remove the jack, hoist or overhead crane
and sling supporting the axle.
13. Carefully raise the machine using a suitable jack or
hoist. Remove the supports from beneath the frame
and lower the machine to the ground.
14. Remove the blocks from the front and rear of both
tires on the other axle.
Note: ALWAYS use new o-rings when servicing the
machine.
15. Install new o-rings into the fittings. Lubricate the
o-rings with clean hydraulic oil.
16. Uncap and connect the steering and brake lines at
their axle fittings.
17. Models 10042 and 10054, Front Axle Only: Install
outrigger assembly. Refer to Section 5.4.6, b.
“Outrigger Installation.”
18. Check the hydraulic reservoir oil level.
19. Properly connect the battery.
20. Remove the Do Not Operate Tags from both the
ignition key switch and the steering wheel.
21. 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.
22. Install the fender assembly (if equipped).
23. Close and secure the rear door.
Note: The service brake circuit will need to be bled after
axle installation. Refer to Section 8.7.4, “Brake Test.”
