2. Lift the spring anchor up and off of the cap screw
(Fig. 32).
3. Install the appropriate hole in the spring anchor onto
the cap screw to increase the idler pulley spring
pressure on the deck idler pulley (Fig. 32).
Note: The ideal deck idler pulley tension is between 30
and 40 pounds of force.
4. Install and tighten the nut onto the cap screw (Fig. 32).

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 linchpin and thrust washer(s) from the top
of the castor wheel fork (Fig. 33).
3. Pull the castor wheel fork out of the mounting tube,
leaving the thrust washer(s) on the bottom of the fork.
Remember the location of the thrust washers on each
fork to ensure correct installation, and to maintain a
level deck.

4. Grease the inside and outside of the new bushings. Use
a hammer and flat plate to carefully drive the bushings
into the mounting tube.
5. Inspect the castor wheel fork for wear and replace if
necessary (Fig. 33).
6. Slide the castor wheel fork through the bushings in the
mounting tube. Replace the thrust washer(s) onto the
fork and secure with the linchpin (Fig 33).
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).
