SERVICING BUSHINGS IN THE CASTOR
ARMS
The castor arms have bushings pressed into the top and bottom por-
tion of the tube which, after many hours of operation, will wear. To
check the bushings, move the castor fork back and forth and from
side to-side. If the castor shaft is loose inside the bushings, bushings
are worn and must be replaced.
1. Raise the cutting unit so its wheels are off the floor and block
it so the cannot accidentally fall.
2. Remove the lynch pin and thrust washers from the top of the
castor spindle.
3. Pull the castor spindle out of the mounting tube. Allow the
thrust washers to remain on the bottom of the spindle.
4. Insert the pin punch into the top or bottom of the mounting
tube and drive the bushing out of the tube (Fig. 9). Also drive
the other bushing out of the tube. Clean the inside of the
mounting tube to remove any dirt.
5. Apply grease to the inside and outside of new bushings. Using
a hammer and flat plate, drive the bushings into the mounting
tube.
6. Inspect the castor shaft for wear and replace if damaged.
7. Push the castor shaft through the bushings and the mounting
tube. Slide the spacers onto the shaft and secure them with a
lynch pin.
