4. Measure the distance from the center of the large clevis
to the air chamber mounting face with the brake fully
released. This is dimension “X” in (Figure 8-46).
5. Using a pry bar, move the slack adjuster so that the
linings contact the drum. Measure the distance between
the same points as in Step 4. This dimension is “Y” in
(Figure 8-46).
6. Subtract dimension “X” from dimension “Y”. The
difference should be 12.7 to 15.9 mm (0.5 to 0.625 in). If
the stroke falls within these limits, no adjustment is
required. If it falls outside these limits, proceed to Step 7.
7. Rotate the adjusting hex approximately 1/8 turn in the
direction required and re-measure the stroke. Continue
this process until the stroke is within limits. A minimum of
17.6 Nm (13 lb-ft) of torque is required to turn the hex
and overcome the internal clutch. A ratcheting noise will
be heard. Do not use an impact wrench or internal
damage will occur (Figure 8-47).
