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
(Fig. 30). 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. 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.
