Servicing the Caster Wheel
and Bearings
The caster wheels rotate on a roller bearing supported by
a spanner bushing. If the bearing is kept well lubricated,
wear will be minimal. Failure to keep the bearing well
lubricated will cause rapid wear. A wobbly caster wheel
usually indicates a worn bearing.
1. Remove the locknut and wheel bolt holding the
caster wheel to the caster fork (Figure 60).

2. Remove one bushing, then pull the spanner bushing
and roller bearing out of the wheel hub (Figure 60).
3. Remove the other bushing from the wheel hub
and clean any grease and dirt from the wheel hub
(Figure 60).
4. Inspect the roller bearing, bushings, spanner bushing
and inside of the wheel hub for wear. Replace any
defective or worn parts (Figure 60).
5. To assemble, place one bushing into the wheel hub.
Grease the roller bearing and spanner bushing and
slide them into the wheel hub. Place the second
bushing into the wheel hub (Figure 60).
6. Install the caster wheel into the caster fork and
secure with the wheel bolt and locknut. Tighten the
locknut until the spanner bushing bottoms against
the inside of the caster forks (Figure 60).
7. Grease the fitting on the caster wheel.
Servicing the Clutch
Checking the Clutch
Service Interval: Every 200 hours—Check the clutch.
If the clutch takes too much time to start the mower deck
or stop the mower deck, the clutch needs adjustment.
To check the clutch, perform steps C, E and F under the
procedure of Removing the Clutch Shim.
