Front Castor Arm Bushing Service

To check the bushings, move castor fork back and forth
and from side to side. If castor spindle is loose inside
the bushings, bushings are worn and must be replaced.

so it cannot fall accidentally.

spindle.

spacer(s) to remain on bottom of spindle.
4. Insert pin punch into top or bottom of mounting tube
and drive bushing out of tube. Also drive other bushing
out of tube. Clean inside of tubes to remove dirt.
5. Apply grease to inside and outside of new bushings.
Using a hammer and flat plate, drive bushings into
mounting tube.
6. Inspect castor spindle for wear and replace it if
damaged.
7. Push castor spindle through bushings and mounting
tube. Slide spacer(s) onto spindle. Install lynch pin on
