7. Label, disconnect and cap the steering and brake
lines at the axle. Cap all fittings to prevent dirt and
debris from entering the hydraulic system. Wipe up
any spilled oil.
8. Block the front and rear of both tires on the axle that
is not being removed. Ensure that the machine will
remain in place during axle removal before
proceeding.
9. Raise the machine using a suitable jack or hoist.
Place suitable supports under both sides of the
frame and lower the machine onto the supports.
Ensure that the machine will remain in place during
axle removal.
10. Support the axle that is being removed with a suitable
jack, hoist or overhead crane and sling. DO NOT
raise the axle or the machine.
11. Remove both wheel and tire assemblies from the
axle that is being removed. (Refer to Section 5.7.1,
“Removing Wheel and Tire Assembly from
Machine.”)
Note: The wheel and tire assemblies must be re-installed
later with the directional tread pattern “arrows” facing in
the direction of forward travel.
12. Remove the drive shaft assembly. Refer to Section
5.6.3, “Drive Shaft Removal.”
13. Remove the capscrew and locknut securing the
lower position cylinder-mount pin to the cylinder. Tap
the cylinder mount pin out, and move the cylinder to
prevent it from interfering with axle removal.
14. Remove the capscrews securing the axle supports
to the machine frame.
15. Remove the axles from the machine using the jack,
hoist or overhead crane and sling supporting the
axle. DO NOT raise or otherwise disturb the
machine while removing the axle. Balance the axle
and prevent it from tipping, turning or falling while
removing it from beneath the machine. Place the
axle on a suitable support or holding stand.
b. 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. Install the capscrews securing the axle to the frame.
Torque to 600-680 lb-ft (813-922 Nm).
Note: If new frame sway (front) or stabilizer (rear)
cylinder bearings (3) 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.
5. Move the cylinder into position on the axle cylinder
anchor. Insert a cylinder-mount pin through the
cylinder and cylinder anchor. Secure the cylinder-
mount pin with one capscrew and new locknut.
6. Apply multi-purpose grease through the self-tapping
lube fitting to lubricate the self-align bearing and the
cylinder-mount pin.
7. Install the drive shaft assemblies. Refer to Section
5.6.5, “Drive Shaft Installation.”
8. 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.
9. Install the wheel and tire assemblies. Refer to
Section 5.7.2, “Installing Wheel and Tire Assembly
onto Machine.”
10. Carefully remove the jack, hoist or overhead crane
and sling supporting the axle.
11. Carefully raise the machine using a suitable jack or
hoist. Remove the supports from beneath the frame
and lower the machine to the ground.
12. Remove the blocks from the front and rear of both
tires on the other axle.
