CLUTCH ADJUSTMENT
(Figure 42)
If clutch fails to engage or disengage properly
or begins to make abnormal noise, check the
air gap adjustment at the three inspection
slots.
To check:
1. Stop engine, remove key and wait for all
hot parts to cool.
2. Measure the air gap between the
armature and the rotor.
• Minimum: A 0.040 cm (0.016") feeler
gauge should slide between armature
and rotor with slight contact.
• Maximum: A 0.050 cm (0.020") feeler
gauge should slide between armature
and rotor with slight contact.
3. Repeat for each inspection slot.
To adjust:
1. If necessary, loosen gap adjustment
nuts until a 0.040 cm (0.016") feeler
gauge fits between armature and rotor.
2. Slide a 0.050 cm (0.020") feeler gauge
between armature and rotor.
3. Tighten gap adjustment nut until there is
slight contact on feeler gauge.
4. Repeat steps 1 – 3 at each inspection
slot.
NOTICE: Adjust air gap as evenly as
possible.
5. Start unit, engage and disengage PTO.
6. Shut off unit.
7. Recheck air gap and adjust if needed.
