1. Using a retaining ring pliers, remove the
retaining ring from the input hub.
2. Rotate the clutch so the brake spring is fully
wrapped down by rotating the output shaft in
the driving direction until it cannot travel any
farther.
3. With the brake spring fully engaged (per step
2), pull the input hub assembly out, and use a
small screwdriver to push the clutch spring out
of its slot, allowing it to move to wherever it
naturally comes to rest.
4. The clutch spring should come to rest between
two slots. Unwrap the spring and push it
backwards into the nearest slot.
5. Push the input hub back into place, release
the actuator and rotate the clutch until the
brake spring is again fully wrapped down. With
the brake fully engaged, hold the output shaft
with one hand and release the actuator. The
stop collar will rotate forward as the brake is
released and the clutch engages.
6. To determine the overtravel, use a scale to
measure the distance between the tip of the
actuator and the tip of the cam.
The amount of overtravel varies with the
size of the unit:
CB-2 .09 to .19"
CB-4 .09 to .19"
CB-5/Super CB-5 .09 to .19"
CB-6/Super CB-6 .22 to .38"
CB-8/Super CB-8 .39 to .60"
7. If the overtravel measurement is within these
specified limits, reinstall the retaining ring and
the unit’s overtravel is reset.
8. A. If the overtravel exceeds the specified limit,
move the brake spring backwards one slot
(against the direction of rotation) and repeat
steps two through six.
