Servicing the Bushings in
the Caster Arms

The caster arms have bushings pressed into the top
and bottom of the tube, and after many hours of
operation, the bushings wear.

To check the bushings, move the caster fork back
and forth and from side to side. If the caster spindle
is loose inside the bushings, the bushings are worn;
replace them.

1.

Park the machine on a level surface, raise and
support the cutting unit with jack stands, engage
the parking brake, shut off the engine, and
remove the key.

2.

Remove the tensioning cap, spacer(s), and
thrust washer from the top of the caster spindle.

3.

Pull the caster spindle out of the mounting tube.
Allow the thrust washer and spacer(s) to remain
on the bottom of the spindle.

4.

Insert a pin punch into the top or bottom of the
mounting tube and drive the bushing out of the
tube (

Figure 31

). Also, drive the other bushing

out of the tube. Clean the inside of the tubes
to remove dirt.

5.

Apply grease to the inside and outside of the
new bushings. Use a hammer and flat plate to
drive the bushings into the mounting tube.

6.

Inspect the caster spindle for wear and replace
it if damaged.

7.

Push the caster spindle through the bushings
and mounting tube, slide the thrust washer
and spacer(s) onto the spindle, and install the
tensioning cap on the caster spindle.

Servicing the Caster
Wheels and Bearings

1.

Park the machine on a level surface, raise and
support the cutting unit with jack stands, engage
the parking brake, shut off the engine, and
remove the key.

2.

Remove the locknut from the bolt holding the
caster wheel assembly between the caster fork
(

Figure 32

). Grasp the caster wheel and slide

the bolt out of the fork or pivot arm.

3.

Remove the bearing from the wheel hub and
allow the bearing spacer to fall out (

Figure 32

).

Remove the bearing from the opposite side of
the wheel hub.

4.

Check the bearings, spacer, and inside of the
wheel hub for wear. Replace any damaged
parts.

5.

To assemble the caster wheel, push the bearing
into the wheel hub. When installing the bearings,
press on the outer race of the bearing.

Slide the bearing spacer into the wheel hub.
Push the other bearing into the open end of the
wheel hub to captivate the bearing spacer inside
the wheel hub.

7.

Install the caster wheel assembly between the
caster fork and secure it in place with the bolt
and locknut.
