Replacing the Caster Wheel
Fork Bushings
The caster wheel forks are mounted in bushings pressed
into the top and bottom of the carrier frame mounting
tubes. To check the bushings, move the caster forks back
and forth and side-to-side. If a caster fork is loose, the
bushings are worn and must be replaced.
1. Raise the cutting unit so the caster wheels are off the
floor, then block up the front of the mower with jack
stands.
2. Remove the locking pin and spacer(s) from the top of
the caster wheel fork (Fig. 66).

3. Pull the caster wheel fork out of the mounting tube,
leaving the spacer(s) on the bottom of the fork.
Remember the location of the spacers on each fork to
ensure correct installation, and to maintain a level
deck.

4. Insert a pin punch into the mounting tube and carefully
drive out the bushings (Fig. 67). Clean the inside of
the mounting tube.
5. Grease the inside and outside of the new bushings. Use
a hammer and flat plate to carefully drive the bushings
into the mounting tube.
6. Inspect the caster wheel fork for wear and replace if
necessary (Fig. 67).
7. Slide the caster wheel fork through the bushings in the
mounting tube. Replace the spacers(s) onto the fork
and secure with the retaining ring (Fig. 66).
Important
The inside diameter of the bushings may
collapse slightly when installed. If the caster wheel fork
does not slide into the new bushings, ream both bushings
to an inside diameter of 1.126 in. (28.6mm).
