Rear Axle Spindle Bushings (Fig. 5)
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) are probably worn and
must be replaced.
1. Remove rear axle from machine (see Rear Axle Re-
moval in this section).
2. Remove two (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 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. Take care not to damage the inside of
the axle tube. Clean the inside of the axle tube to remove
any dirt or foreign material.
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 axle tube. The bushings must
be flush with the axle tube.
6. Thoroughly clean the spindle shaft. Inspect the
spindle for wear and replace if worn or damaged.

7. Install two thrust washers (items 10 and 5) onto the
spindle 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), thrust
washer (item 5) and retaining ring (item 4) onto the end
of the spindle shaft.
8. End play of spindle should be .030" to .090" (.8 to 2.3
mm) after assembly. If necessary, adjust end play by
adding or removing flat washers (items 6 and 7).
9. Install the spindle cap and cap screw.
10.Connect the tie rod end to the spindle bracket with
flat washer and two (2) jam nuts. Tighten the first jam nut
and then tighten the second jam nut against the first to
secure tie rod end to spindle.
11. Install rear axle to machine (see Rear Axle Installa-
tion in this section).
12.Lubricate the steering spindles through the grease
fittings on the rear axle (see Traction Unit Operator's
Manual).
13.Check rear wheel toe−in (see Traction Unit Opera-
tor's Manual).
14.After all adjustments have been made, make sure
that no contact is made between any steering compo-
nents as the wheels are moved from lock to lock. Re-
adjust if necessary.
