Servicing Front 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
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.
1. Raise cutting unit so wheels are off floor and block it
so it cannot fall accidentally
.
2. Remove tensioning cap, spacer(s) and thrust wash-
er from top of castor spindle.
3. Pull castor spindle out of mounting tube. Allow
thrust washer and 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 dam-
aged.
7. Push castor spindle through bushings and mount-
ing tube. Slide thrust washer and spacer(s) onto spindle.
Install tensioning cap on castor spindle to retain all parts
in place.
