Brake Gap (G) - The Brake Gap should be measured between the Brake Drum and Pull Rotor.
Adjustment of the Brake Gap is accomplished by turning the Adjustment Nut in the center of the
Motor Cover as shown in the figure with
Table 6-9
. Do this as follows:
1)
Bend the tab of the Lock Washer away from the Adjusting Nut so that the Adjusting Nut can be
rotated.
2)
Using a spanner wrench and a feeler gauge, rotate the Adjusting Nut to attain the proper Brake
Gap per
Table 6-9
.
3)
After the Brake Gap is set, secure the Adjusting Nut by bending one of the tabs of the Lock
Washer into a slot in the Adjusting Nut. If necessary rotate the Adjusting Nut clockwise (tightening)
to line up the tab with the slot.
4)
If the proper brake adjustment cannot be achieved, disassemble the motor brake and inspect all
motor brake parts. Replace the Brake Drum and/or Motor Cover if necessary.
