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. NOTE: 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. 4 4 3 1. Armature 2. Rotor 21 3. Inspection Slot 4.
