Removal (Fig. 15)
1. Engage the parking brakes, lower the cuttingunits to
the ground, turn the engine OFF and remove the key
from the ignition switch.
2. Drain rear axle lubricant (see Changing Rear Axle
Lubricant in this section of this manual).
3. Thoroughly clean the steering cylinder and rear axle
drive motor hydraulic hoseconnections. Disconnect the
hydraulic hoses and put caps or plugs on all the fittings
and hoses to prevent contamination.
Note: To ease reassembly, tag each of the hoses to
show their correct position.
4. Remove the retaining rings securing therod end and
the barrel end of the steering cylinder and remove the
steering cylinder.
5. Removethe cotterpins and slotted hex nuts from the
tierod balljoints. Use aball jointfork andremove theball
joints from the axle case supports.
6. Loosen the rear wheel lug nuts.
7. Remove the locknut and thrust washer securing the
end of the axle pivot pin to the chassis.
8. Block the front wheels and jack up the frame (just
ahead of the rear wheels) until the rear tire is about 1 in.
(25 mm) above the floor. Support the machine with jack
stands to prevent it from falling.
9. Remove rear wheels.
10.Support the rear axle from underneath and remove
the axle pivot pin. This will release the rear axle and
washer(s) from the frame, allowing the axle to be low-
ered and removed.
Note: Several washers may have been installed be-
tween the axle pivot tube and frame during manufac-
ture. Make sure the same number of washers are
installed in the same location during reassembly.
11.Wipe the rear axle pivot pin and pivot bushings with
a rag to remove dirt and grease. Inspect the pin and
bushings for wear or damage. Replace components as
necessary.
Installation (Fig. 15)
1. Apply a thin coat of grease to the inside of the rear
axle pivot bushings and move the rear axle assembly
into position under machine frame.
2. Install washer(s) and axle pivot pin. Secure the axle
pivot pin in place with the thrust washer and locknut.
3. Installthe tie rod ball joints and check rear wheel toe-
in (see Rear Wheel Toe-in Adjustment in this section of
this manual). Tighten ball joint hex nuts and install new
cotter pins.
4. Install steering cylinder and cylinder retaining rings.
5. Install rear wheels and lug nuts.
6. Removethejackstandsandlowerthemachineto the
floor.
7. Tighten rear wheel lug nuts to 85 to 100 ft-lbs. (115
to 136 Nm).
8. Lubricate the rear axle pivot bushings through the
grease fitting on the pivot pin.
9. Fill rear axle with lubricant (see Changing Rear Axle
Lubricant in this section of this manual).
10.Install the hydraulic hoses to the steering cylinder
and rear axle drive motor.
11.Check steering cylinder and rear axle hydraulic con-
nections for leaks.
12.Check steering stop bolt adjustment on both side of
rear axle. When the steering cylinder is fully extended
(either direction), a gap of 1/16” (1.6 mm) should exist
between bevel gear case casting and stop bolt on axle
case. Figure 16 shows stop bolt location.
