Servicing the Bushings in the
Castor Arms
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 29). Also drive the other bushing out of the
tube. Clean the inside of the tubes to remove dirt.
