Servicing the Castor Arm
Bushings
The castor arms have bushings pressed into the
top and bottom of the tube and after many hours
of operation, the bushings will wear. To check the
bushings, move the castor fork back and forth and
from side to side. If the castor spindle is loose inside
the bushings, the bushings are worn and must be
replaced.
1.
Raise the cutting unit so that the wheels are
off of the floor. Block the cutting unit so that it
cannot accidentally fall.
2.
Remove the tensioning cap, spacer(s), and
thrust washer from the top of the castor spindle.
3.
Pull the castor 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
107). Also drive the other bushing
out of the tube. Clean the inside of the tubes
to remove dirt.

Apply grease to the inside and outside of the
new bushings. Using a hammer and flat plate,
drive the bushings into the mounting tube.
6.
Inspect the castor spindle for wear and replace
it if it is damaged.
7.
Push the castor spindle through the bushings
and mounting tube. Slide the thrust washer and
spacer(s) onto the spindle. Install the tensioning
cap on the castor spindle to retain all parts in
place.
