Figure 7.4.6

Use a feeler gauge to measure the brake gap (see Figure 7.4.7).

Figure 7.4.7

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.

If the proper brake adjustment cannot be achieved, disassemble the motor brake and inspect all motor brake
parts. Replace the brake pad if necessary.

7.5

Hoist Motor Brake Disassembly

Loosen and remove socket head cap screw and spring washers securing the motor shell (see Figure 7.4.1).

Carefully pull the motor brake unit out of the hoist (see Figure 7.4.2).

Remove the rubber cover (see Figure 7.4.4).

Bend the tab of the lock washer away from the adjusting nut so that the adjusting nut can be rotated (see
Figure 7.4.5).

Remove the adjusting nut, lock washer and washer (see Figure 7.5.1).
