CLUTCH ADJUSTMENT
If clutch fails to engage or disengage properly

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 .016" feeler gauge should
slide between armature and rotor with
slight contact.
Maximum: A .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 .016" feeler gauge fits between
armature and rotor.
2. Slide a .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.
