Rear Axle Bushing Service
The rear axle must be held in place snugly by the axle
pin. Excessive movement of the axle, which is charac­
terized by erratic steering, usually indicates worn bush­
ings. To correct the problem, replace the bushings.
1. Disconnect the hydraulic hoses from the steering
cylinder. 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 on the steering cylinder.
2. Remove the cap screw securing the end of the axle
pin to the chassis (Fig. 16).
3. Jack up the frame (just ahead of the rear wheels) until
pressure is taken off the axle pin. Support the machine
with jack stands to prevent it from falling.
4. Pull the axle pin out. This will release the rear axle
and washer(s) from the frame. Carefully pull the entire
axle and wheel assembly out from under the machine.
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 during reassembly.
5. Use a drift punch and hammer to drive both bushings
out of the axle. Clean the inside of the axle pivot tube to
remove dirt and foreign material.
6. Apply grease to the inside and outside of the new
bushing. Use an arbor press to install the bushings into
the top and bottom of the axle pivot tube. Bushings must
be flush with the axle tube.
7. Wipe the rear axle pin with a rag to remove dirt and
grease. Inspect the pin for wear or damage and replace
as necessary.
8. Mount the axle to the frame with the axle pin. The
washer(s) must be positioned between the rear end of
the pivot tube and the frame (see the NOTE after
step 3). Secure the axle pin in place with the cap screw.
9. Remove the jackstands and lower the machine to the
floor.
10. Install the hydraulic hoses to the steering cylinder.
11. Lubricate the rear axle bushings through the grease
fitting on the rear axle.
Steering Pivot Bushing Service
The steering pivot must fit snugly onto the mounting pin.
Excessive movement of the steering pivot may indicate
worn bushings or tie rod ball joints.
1. Remove the lock nut and cap screw securing the
steering cylinder rod end to the steering pivot (Fig. 16).
2. Remove two (2) nuts to disconnect the tie rod end
from the spindle arm. Inspect all tie rod end ball joints
for wear or damage and replace as necessary.
3. Remove the retaining ring and thrust washer. Slide
the steering pivot off of the mounting pin on the bottom
of the axle.
4. Use a drift punch and hammer to drive both bushings
out of the steering pivot. Clean the inside of the steering
pivot to remove dirt and foreign material. Also clean the
mounting pin on the bottom of the rear axle.
5. Apply grease to the inside and outside of the new
bushings. Use an arbor press to install the bushings into
the top and bottom of the steering pivot tube. Bushings
must be flush with the end of the tube.
6. Slide the steering pivot onto the mounting pin. Secure
the plate in place with the thrust washer and retain­
ing ring.
