6.6.7 SPINDLE AND CONE ADJUSTMENT
This procedure must be performed whenever the spindle and cone are out of align-
ment or whenever the actuator assembly is removed or replaced.
a. Loosen chassis support assembly (Figure 6-9 ).
b. Positionchassis assembly by pushing down on the spindle cone shaft so cone seats
in the spindle (Figure 6-11).
c. Slowly close door without spindle turning. Spindle top surface and cone spindle
contact surface must meet at the same time on the full circumference of the
spindle (see Figure 6-11).
d. Complete door closing slowly. Visually verify that all segments on the cone that
can be seen are fully seated in the spindle. Slowly rotate spindle and verify that
all cone segments are seated and that the segments do not seat as the spindle is
rotated as evidenced by a "clicking" sound or observing the segments seating.
e. Repeat fully opening and closing door four times. Verify that after each closing
all cone segments are fully closed. Verify that the load arm does not bind when
door is opened and closed.
f. Secure socket head screws (Figure 6-9 ) and again recheck steps "c" through "e".
