General Adjustment Guidelines
As a general guideline for reference, there should be about three threads showing
in the motor brake end cap when the outer air gap adjustment ring is turned in. The
end of the tension shaft should barely protrude through the tension adjustment
locknut by no more than 1/8 inch (3.2 mm).
Adjusting the Spring Tension
To increase the spring tension, turn the tension adjustment locknut (6)
counterclockwise.
To
decrease the spring tension, turn the tension adjustment locknut (6) clockwise.
NOTE: The tension adjustment locknut (6) has left-handed threads.
Adjusting the Air Gap
The nominal recommended air gap is 0.025 inches (0.635 mm). When adjusting
the air gap, the rotor (1), bearing (9), and bearing locknut (10) move in or out as
the adjustment is being made. However, the tension pin (2), tension spring (3),
tension shaft (4), washer (5), tension adjustment locknut (6), and brake (7) all
remain fixed in reference to the motor brake end cap (11).
To Increase Air Gap (Decrease Brake Tension)
9. Loosen the three hex head screws (14).
10. Turn the outer air gap adjustment ring (12) clockwise.
11. Tighten the three hex head screws (14).
To Decrease Air Gap (Increase Brake Tension)
1. Loosen the three hex head screws (14).
2. Turn the outer air gap adjustment ring (12) counterclockwise.
3. Tighten the three hex head screws (14).
