Caster Wheel and Bearings
Service
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 (Fig. 67).
2. Remove one bushing, then pull the spanner bushing
and roller bearing out of the wheel hub (Fig. 67).
3. Remove the other bushing from the wheel hub and
clean any grease and dirt from the wheel hub (Fig. 67).
4. Inspect the roller bearing, bushings, spanner bushing
and inside of the wheel hub for wear. Replace any
defective or worn parts (Fig. 67).

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 (Fig. 67).
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 (Fig. 67).
7. Grease the fitting on the caster wheel.
Replacing the Grass Deflector
An uncovered discharge opening could allow the
lawn mower to throw objects in the operator’s or
bystander’s direction and result in serious injury.
Also, contact with the blade could occur.
Never operate the lawn mower unless you install a
cover plate, a mulch plate, or a grass chute and
catcher.
Warning
1. Remove the locknut, bolt, spring and spacer holding
the deflector to the pivot brackets (Fig. 68). Remove
damaged or worn grass deflector.
2. Place spacer and spring onto grass deflector. Place the
L end of spring behind deck edge.
Note: Make sure the L end of spring is installed behind
deck edge before installing the bolt as shown in figure 68.
3. Install bolt and nut. Place the J hook end of spring
around grass deflector (Fig. 68).
Important
The grass deflector must be able to lower
down into position. Lift the deflector up to test that it
lowers into the full down position.
