Replacing the Castor Wheel
Fork Bushings
The castor wheel forks are mounted in bushings
pressed into the top and bottom of the carrier frame
mounting tubes. To check the bushings, move the
castor forks back and forth and side-to-side. If a
castor fork is loose, the bushings are worn and must
be replaced.

1. Raise the cutting unit so the castor 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 castor wheel fork (Fig. 59).
3. Pull the castor 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. 60). 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 castor wheel fork for wear and replace if
necessary (Fig. 59).
7. Slide the castor wheel fork through the bushings in the
mounting tube. Replace the spacer(s) onto the fork and
secure with the retaining ring (Fig 59).
Important
The inside diameter of the bushings may
collapse slightly when installed. If the castor wheel fork
does not slide into the new bushings, ream both bushings
to an inside diameter of 1.126 in. (28.6mm).
