Axles, Wheels and Tires
5.3.6 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 rear axle.
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 axle
housing with the holes in the frame.
5. Install the pivot pin and replace the shims on each
end of the axle. Install the pivot pin lockbolt and nut.
6. Move the sway cylinder into position on the axle
cylinder anchor. Insert the pin through the cylinder
and cylinder anchor. Secure the cylinder-mount pin
with the retaining clip.
7. Tighten the axle oil drain plug, loosen and remove
the axle oil fill plug (3). (Refer to Section 2.4, “Fluid
and Lubricant Capacities,” for proper oil and
capacities.
8. Rotate wheel hubs 90 degrees so the drain plug (4)
becomes the fill plug. Refer to Section 2.4, “Fluid
and Lubricant Capacities,” for proper oil and
capacities.
9. Install the wheel and tire assemblies. Refer to
Section 5.6.2, “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.
Note: ALWAYS use new o-rings when servicing the
machine.
13. Install new o-rings into the fittings. Lubricate the
o-rings with clean hydraulic oil.
14. Uncap and connect the brake lines at their axle
fittings.
15. Install the drive motor assembly.
16. Check the hydraulic reservoir oil level.
17. Connect the battery negative (-) cable from the
battery negative (-) terminal and install the deck
cover.
18. Close and secure the engine cover.
19. Start the engine. Operate the frame sway function
several times in both directions and check the
function of the brakes. Check for hydraulic leaks, and
tighten or repair as necessary.
Note: The service brake circuit will need to bled after
axle installation. Refer to Section 8.8.3, “Brake Test.” MX0600
