Rear Wheel Spindle Bushings
The rear wheel spindles must fit snugly in the rear axle.
Excessive movement of the spindle in the axle indicates
that the bushings are probably worn and must be re-
placed.
1. Disconnect the hydraulic hoses from the steering
cylinder. Put caps or plugs on 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 jamnut and thrust washer securing the
end of the axle pivot pin to the chassis (Fig. 14).
3. Jack up the frame (just ahead of the rear wheels) un-
til pressure is taken off the axle pivot pin. Support the
machine with jackstands to prevent it from falling.
4. Pull the axle pivot pin out. This will release the rear
axle and washer(s) from the frame. Carefully pull the en-
tire axle and wheel assembly out from under the ma-
chine.
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. Remove one (1) jamnut to disconnect the tie rod end
from the spindle arm.
6. Remove the capscrew, spindle cap, retaining ring,
and washers that secure the wheel spindle into the axle
tube. Slide the spindle, washer, and wheel assembly out
of the axle tube to expose the bushings.
7. Use a punch and hammer to drive both bushings out
of the axle tube. Clean the inside of the axle tube to re-
move any dirt and foreign material.
8. 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 axle tube. The bushings must
be flush with the axle tube.
9. Wipe the spindle shaft with a rag to remove any dirt
and grease. Inspect the spindles for wear and replace
as necessary.
10.Install a washer onto the spindle shaft and push the
shaft through the axle tube. Hold the wheel and spindle
shaft assembly in place and install the thrust washer flat
washer and retaining ring onto the end of the spindle
shaft. Install the spindle cap and capscrew.
11. Connect the tie rod end to the spindle bracket with
two (2) jamnuts. Tighten the first nut to a torque of 25
to33 ft-lbs. (34 to 45 Nm). Install the second jamnut and
tighten against the other nut to secure tie rod end.
12.Mount the axle to the frame with the axle pin. Install
washer(s) and axle pivot pin. Secure the axle pivot pin
in place with the thrust washer and jamnut.
13.Remove the jackstands and lower the machine to the
floor.
14.Lubricate the steering spindles through the grease
fittings on the rear axle.
15.Install the hydraulic hoses to the steering cylinder.
16.Check steering cylinder hydraulic connections for
leaks.
