Adjusting the Electric Clutch

Service Interval: Every 500 hours—Check the electric
clutch.
The clutch is adjustable to ensure proper engagement and
proper braking.
1. Insert a 0.38 to 0.53 mm (0.015–0.02 inch) feeler gauge
through one inspection slot in the side of the assembly.
Note: Make sure it is between the armature and the
rotor-friction surfaces.
Note: The gap needs to be at least 0.38 mm (0.015
inch), and not more than 0.53 mm (0.02 inch).
2. If adjustment is needed, then set at 0.38 mm (0.015
inch) for each of the three adjustment slot positions.
3. Tighten the locknuts until there is a slight binding on
the feeler gauge, but it can be moved easily within the
air gap (Figure 54).
4. Repeat this for the remaining slots.
5. Check each slot again and make slight adjustments until
the feeler gauge between the rotor and armature with
