CARE AND MAINTENANCE
PROCEDURE FOR ELECTRIC CLUTCH ADJUSTMENT:
Electric clutches require periodic Air Gap adjustments for extended
life. Listed below is both an Air Gap adjustment procedure and an
Ohms test to check for a faulty coil within the clutch. No replacement
parts are available to repair a faulty assembly. The entire clutch must
be replaced.
A. AIR GAP ADJUSTMENT
1. It is not necessary to remove the clutch from the motor.
2. Locate the three holes in the brake plate, one near each
adjustment nut. (Figure 1)
3. Insert a .012” feeler gauge into one of the three windows.
Be careful to position the feeler gauge between the rotor
and armature faces. (Figure 2)
4. Tighten the adjustment nut adjacent to the window with
the feeler gauge inserted until the gauge fits snugly
between the rotor and armature. The gap should not be
so tight that the feeler gauge cannot be reinserted after
removal.
5. Repeat steps 5 and 6 at the other two windows.
6. Re-check the air gap at each window and make minor
adjustments as necessary to achieve a consistent .012”
air gap.
