CLUTCH ADJUSTMENT

If clutch fails to engage or disengage properly
or begins to make abnormal noise, check the
air gap adjustment at the three inspection
slots. See Figure 33.
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 0.041 mm (0.016") feeler
gauge should slide between armature
and rotor with slight contact.
• Maximum: A 0.051 mm (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 0.041 mm (0.016") feeler gauge fits
between armature and rotor.
2. Slide a 0.051 mm (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.

NOTICE: NOTICE: Gravely recommends
using a quality fuel stabilizer in all fuel.
Gasoline left in the fuel system without a
stabilizer, even for short periods of time,
deteriorates and leaves gummy deposits in
the system that may damage the carburetor
and fuel hoses, filter and tank. For the best
effectiveness, add stabilizer to all fuel
containers whenever purchasing fuel. Add
the stabilizer to the container before adding
