14-31. CONDENSER DOOR ACTUATOR.

The actuator is on a bracket mounted between two bulkheads in tail cone. It is coupled to the
c o ndenser assembly through a bellcrank mounted to a bracket on bulkhead aft of condenser. Actuator travel is
controlled by two limit switches. Both up and down switches are on the actuator. Refer to Figure 14-11 for
switch locations.
14-32. CONDENSER DOOR ASSEMBLY RIGGING INSTRUCTIONS. (Refer to Figure 14-11.)
The condenser assembly is actuated by an electric motor through bellcranks, push rods, and limit
switches. Condenser door must fit flush with fuselage skin, and with increased force along forward edge. Use
the following steps:
a. Adjust open limit switch to open condenser door 5.00 inches measured from leading edge of door
to fuselage skin.
b. Adjust side push rods so a vertically measured gap of 0.156 inch exists along trailing edge of door
at the instant forward edge of door is flush with fuselage skin.
c. Fully close door and adjust CLOSED limit switch so actuator travels an additional 0.12 inch with
door fully closed, (required to pre-load mechanism). (Refer to Figure 14-11.)
d. Cycle assembly several times. Verify proper operation without binding.
