slide between armature and rotor with
slight contact.

slide between armature and rotor with
slight contact.

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.
