10.3.6.2 Adjusting the Air Gap
The nominal recommended air gap is 0.025 inches (0.635 mm). The air gap is measured
between the rotor and the end of brake pad assembly. When adjusting the air gap; the rotor,
rear rotor bearing, and bearing locknut move in or out as the adjustment is being made.
However; the tension pin, tension spring, tension shaft, washer, tension adjustment locknut,
and brake, all remain fixed in reference to the motor end cap. After the air gap is adjusted the
brake tension will need to be re-adjusted.
Check the air gap by measuring with a feeler gauge between the rotor and brake assembly.

To decrease the air gap
1. Remove the motor cooling fan
2. Loosen the three hex head capscrews on the back of the motor end cap (do
not remove the three hex head capscrews). Loosen them evenly a ½ turn by
turning counterclockwise to control the inner air gap adjustment ring.
3. Loosen the outer air gap adjustment ring counterclockwise the amount of
distance wanting to be removed from the air gap
4. Tighten the three hex head capscrews by turning them evenly clockwise to
control the inner air gap adjustment ring and move the rotor bearing to the
outer air gap adjustment ring. This process will move the rotor closer to the
brake assembly to achieve the proper air gap measurement.
5. Ensure the outer air gap adjustment ring can not be tightened against the end
rotor bearing. Tighten the three hex head capscrews clockwise evenly until
snug. Once all three are snug, turn each hex head capscrew 1/2 turn to lock
in the air gap adjustment.
6. Re-install the motor end cap
7. Perform a brake tension test
CAUTION
To adjust the brake air gap the rotor will need to be removed from the motor.
CAUTION
The brake tension needs to be re-adjusted after the brake air gap is adjusted.
