5. Use a drift punch and hammer to drive both the steering pivot bushings
out of the steering pivot. Clean the inside of the steering pivot to remove
any dirt or unwanted material. Also, clean the mounting pin at the bottom
of the rear axle.
6. Apply grease to the inner and outer surfaces of new bushings. Use an arbor
press to install the bushings into the top and bottom of the steering pivot.
The bushings must be flush with the pivot plate.
7. Slide the steering pivot onto the axle mounting pin. Secure the pivot in place
with the thrust washer and retaining ring.
8. Connect each tie rod end to the pivot with the 2 jam nuts. For each tie rod,
tighten the first jam nut and then tighten the second jam nut against the
first to secure the tie rod end.
9. Install the thrust washer, bolt, and locknut to secure the steering cylinder rod
end to the steering pivot plate
203 N·m (130 to 150 ft-lb).
10. Lubricate the bushings through the grease fitting on the steering pivot plate.
The rear wheel spindles must fit snugly in the rear axle. Excessive movement of
the spindle in the axle indicates that the spindle bushings (item 8 in
are probably worn and must be replaced.
1. Remove the rear axle from the machine; refer to
(page 7–11).
2. Remove the 2 jam nuts and flat washer that secure the tie rod end to the
spindle arm. Disconnect the tie rod end from the spindle arm.
3. Remove the flange-head screw, spindle cap, retaining ring, and washers that
secure the wheel spindle into the axle tube. Slide the spindle, washers, and
wheel assembly out of the axle tube to expose the spindle bushings.
4. Use a punch and hammer to drive both bushings out of the axle tube. Ensure
that you do not damage the inner surface of the axle tube. Clean the inner
surface of the axle tube to remove any dirt or unwanted material.
5. Apply grease to the inner and outer surfaces of new bushings. Use an arbor
press to install the bushings into the top and bottom of the axle tube. The
bushings must be flush with the axle tube.
6. Clean the spindle shaft. Inspect the spindle for wear and replace if worn
or damaged.
7. Install the 2 thrust washers (items 10 and 5 in
shaft and slide the shaft up through the axle tube. Hold the wheel and spindle
shaft assembly in place and install the flat washer(s) (items 7 and 6 in
182), thrust washer, and retaining ring onto the end of the spindle shaft.
8. End-play of spindle should be 0.8 to 2.3 mm (0.030 to 0.090 inch) after
assembly. If necessary, add or remove the flat washers (items 6 and 7 in
Figure 182) to adjust end-play.
9. Install the spindle cap and secure with the flange-head screw.
10. Connect the tie rod end to the spindle bracket with the flat washer and 2 jam
nuts. Tighten the first jam nut and then tighten the second jam nut against
the first to secure the tie rod end to the spindle.
11. Install the rear axle to the machine; refer to
7–12).
