4. Insert the release stud
through the opening in the
spring chamber where the
cap was removed. Insert it
into the pressure plate. Turn
the release stud 1/4-turn
clockwise in the pressure
plate. This secures the
cross pin into the cross pin
area of the pressure plate
and locks it into the manual
release position.
5. Assemble the release stud
washer and nut on the
release stud.
6. With a wrench, turn the
release stud assembly nut
until the compression spring
is 90% - 95% caged. While
doing this, check to make
sure the push rod (adapter
push rod or service push rod)
is retracting. Do not over-
torque the release stud
assembly [S-Cam type maxi-
mum 50 Lb. ft. (68 N.m.);
Wedge-type maximum 30 Lb.
ft. (41 N.m.)]. The spring
brake is now mechanically
released.
