Caster Arm Bushing Service (Fig. 12)
The caster arms have bushings pressed into the top and
bottom portion of the tube and after many hours of
operation, the bushings will wear. To check the bush-
ings, move caster fork back and forth and from side-to-
side. If caster spindle is loose inside the bushings,
bushings are worn and must be replaced.
1. Raise cutting unit and block it so it cannot fall acci-
dentally.
2. Remove lynch pin and spacers from top of caster
spindle.
3. Pull caster spindle out of mounting tube. Allow
spacer(s) and thrust washer to remain on bottom of
Figure 12
spindle to assure same height of cut when caster spin-
dle is reinstalled.
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 caster spindle for wear and replace it if
damaged.
7. Push caster spindle through bushings and mounting
tube. Slide spacers onto spindle. Install lynch pin
through caster spindle to retain all parts in place.
