3. Remove the other bushing from the wheel hub
and clean any grease and dirt from the wheel hub
(Figure 57).
4. Inspect the roller bearing, bushings, spanner bushing
and inside of the wheel hub for wear. Replace any
defective or worn parts (Figure 57).
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 57).
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 57).
7. Grease the fitting on the caster wheel.
Adjusting the Electric Clutch
Service Interval:
Every 100 hours—Check the electric
clutch.
The clutch is adjustable to ensure proper engagement
and proper braking.
1. Insert a 0.015–0.021 inch (0.381–0.533 mm) feeler
gauge through one inspection slot in the side of the
assembly. Make sure it is between the armature and
the rotor friction surfaces.
2. Tighten the lock nuts until there is slight binding on
the feeler gauge but it can be moved easily within the
air gap (Figure 58).
3. Repeat this for the remaining slots.
4. Check each slot again and make slight adjustments
until the feeler gauge between the rotor and armature
with very slight contact between them.

Cleaning the Air Intake Screen
Service Interval:
Before each use or daily
Before each use remove any build-up of grass, dirt
or other debris from the cylinder and cylinder head
cooling fins, air intake screen on flywheel end, and
carburetor-governor levers and linkage. This will help
insure adequate cooling and correct engine speed and
will reduce the possibility of overheating and mechanical
damage to the engine.
Cleaning the Cooling System
Service Interval:
Every 100 hours—Check and clean
engine cooling fins and shrouds.
1. Disengage the PTO and set the parking brake.
2. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
3. Remove the air intake screen and fan housing
(Figure 59).
4. Clean the debris and grass from the engine parts.
5. Install air intake screen, recoil starter and fan housing
(Figure 59).
