Axle Pivot Bushings
The rear axle must be held in place snugly by the axle pivot pin. Excessive
movement of the axle, which is characterized by erratic steering, can indicate
worn axle pivot bushings. To correct the problem, replace the axle pivot bushings
(item 24 in
Figure 182 ).
1. Remove the rear axle from the machine; refer to Removing the Rear Axle
(page 7–11) .
2. Use a drift punch and hammer to drive both axle pivot bushings out of the
axle pivot tube. Clean the inside of the tube to remove any dirt or unwanted
material.
3. Apply grease to the inner and outer surfaces of new bushings. Use an arbor
press to install the bushings into the front and back of the axle pivot tube.
The bushings must be flush with the axle tube.
4. Install the rear axle to the machine; refer to Installing the Rear Axle (page
7–12) .
5. Lubricate the bushings through the grease fitting on the axle pivot tube.
Steering Pivot Bushings
The steering pivot must fit snugly onto the mounting pin. Excessive movement of
the steering pivot may indicate worn steering pivot bushings (item 21 in
Figure
182 ) or tie rod ball joints (item 15 and 16 in Figure 182 ).
1. Park the machine on a level surface, lower cutting deck (or implement), shut
off the engine, set the parking brake, and remove the key from the key switch.

2. Remove the locknut, bolt, and thrust washer that secure the steering cylinder
rod end to the steering pivot plate ( Figure 183 ).
3. Remove the 4 jam nuts to allow both tie rod ends to be disconnected from
the pivot plate. Inspect all the tie rod end ball joints for wear or damage
and replace as necessary.
4. Remove the retaining ring and thrust washer that secure the steering pivot
plate (item 22 in Figure 182 ) to the rear axle. Slide the steering pivot off of
the mounting pin at the bottom of the axle.
