Servicing the Caster-Arm
Bushings
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.
Remove the tensioning cap and caster fork ( Figure
138 ).
Note:
Record the position of the washers and
spacers before you remove them so that you do not
need to adjust the deck pitch.

the cutting unit caster-wheel
assemblies.
1. Remove the locknut from the bolt holding the
caster-wheel assembly between the caster fork
or the caster-pivot arm (
Figure 139 ).

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

5. Check the bearings, spacer, and inside of the
wheel hub for wear.
Note:
Replace any damaged parts.
6. To assemble the caster wheel, push the bearing
into the wheel hub.
Note:
When installing the bearings, press on
the outer race of the bearing.
7. Slide the bearing spacer into the wheel hub and
push the other bearing into the open end of the
wheel hub to captivate the bearing spacer inside
the wheel hub.

caster fork and secure it in place with the bolt
