The clutch is adjustable to ensure proper engagement and
proper braking.
1. Insert a 0.015–0.021 inch (0.381–0.533 mm) feeler
gauge through one inspection slot in the side of the
assembly. Make sure it is between the armature and
the rotor friction surfaces.
The gap needs to be at least .015 inches (0.381 mm)
and not more than .021 inches (0.533 mm).
2. If adjustment is needed, then set at .015 inches (0.381
mm) for each of the three adjustment slot positions.
Tighten the lock nuts until there is slight binding on
the feeler gauge but it can be moved easily within the
air gap (Figure 53).
3. Repeat this for the remaining slots.
4. Check each slot again and make slight adjustments until
the feeler gauge between the rotor and armature with
very slight contact between them.
