3. The dual thread release bolt which reduces the travel of
the release bolt by a factor of 2.4. in a 76 mm (3.00 in)
stroke unit, for instance, the parking spring is fully caged
when the release bolt is up approximately 33 mm (1.3 in)
from the run position (Figure 8-48). After caging,
completely exhaust air from the spring chamber.
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 8-49)
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 8-49).
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.
CAUTION
Do not exceed the length stated in step 3 and do not
exceed 68 Nm (50 lb) torque on release bolt at any time or
damage may occur which could prevent any further
correct manual release of the spring brake chamber.
