Axle Assembly Removal and Installation
1. Put machine on a level surface, lower cutting units,
stop the engine and remove key from ignition switch.
Block rear wheels to prevent machine from moving.
2. Remove the cutting units (See the Repairs section of
Chapter 8 - Cutting Units).
3. If unit is equipped with 4WD, remove rear axle drive
shaft (see Chapter 9 - 4WD Rear Axle). Remove nut,
pinion spacer and pinion coupler.
4. Remove hydrostatic transmission. (See Repairs
section of Chapter 4 - Hydraulic System.) Keep trans-
mission support attached to frame and gear pump at-
tached to transmission support.
5. Slightly loosen all front wheel lug nuts. Jack both
front wheels off the ground and install jackstands or
blocks under traction unit frame (not axle tubes) to pre-
vent machine from falling. Remove both front wheels.
6. Remove the cotter pin and clevis pin to disconnect
the brake cable from brake actuating lever on each
brake. Loosen jam nut to remove brake cable from each
end of axle bracket. Disconnect speedometer sensor

7. Put a jack or block under differential to hold it in
place. Remove cap screws and lock nuts securing axle
mounting pads to frame. Carefully lower differential axle
and pull it out from under traction unit.
8. To install axle, reverse steps 1 - 9. Apply silicone
sealant between axle housing and transmission sup-
port. Leave axle mounting pad nuts loose. Install shims
(P/N 42-6080) between axle mounting pads and frame
to align differential with transmission support, then tight-
en axle mounting nuts.
9. Before installing pinion coupler, apply Permatex
No. 2 to external splines of pinion and internal splines of
pinion coupler. Tighten nut securing pinion coupler to 75
to 90 ft-lbs (100 to 122 Nm).
