Axles, Drive Shafts, Wheels and Tires

14. 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.

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 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 axle

housings with the holes in the frame.

5. Install the four axle bolts and nuts. Tighten and

torque to 340-365 lb-ft (460-495 Nm) on the G6-42A.

Torque bolts to 530-560 lb-ft (718-759 Nm) on the

G9-43A and G10-43A.

6. 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 a new locknut.

7. Apply multi-purpose grease through the self-tapping

lube fitting to lubricate the self-align bearing and the

cylinder-mount pin.

8. Install the drive shaft assemblies. (Refer to Section

5.4.5, “Drive Shaft Installation.”)

9. 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.

10. Tighten the axle oil drain plugs (1), loosen and

remove the axle oil fill plug (3) and sight plugs (4).

(Refer to Section 2.4, “Fluid and Lubricant

Capacities,” for proper oil and capacities.

11. Rotate wheel hubs 90 degrees so the drain plug

becomes the fill plug (2). Refer to Section 2.4, “Fluid

and Lubricant Capacities,” for proper oil and

capacities.

12. Install the wheel and tire assemblies. Refer to

Section 5.5.2, “Installing Wheel and Tire Assembly

onto Machine.”

13. Carefully remove the jack, hoist or overhead crane

and sling supporting the axle.

14. Carefully raise the machine using a suitable jack or

hoist. Remove the supports from beneath the frame

and lower the machine to the ground.

15. 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.

16. Install new o-rings into the fittings. Lubricate the

o-rings with clean hydraulic oil.

17. Uncap and connect the steering and brake lines at

their axle fittings.

18. Check the hydraulic reservoir oil level.

19. Properly connect the battery.
