C. Installation of the Air-Intake Flap Actuator
(1)
Hold the air intake flap in the top position.
(2)
Make sure that the new air-intake flap actuator (6) is in the flap open position (retracted).
NOTE : Turn the manual override device on the air-intake flap
____ actuator with a torque wrench until the actuator rod is in the retracted position (which agrees with the open position of the air intake flap). For the 43-1-1100 Amendment 1 actuator a torque up to 0.3 m.daN (26.54 lbf.in) is permitted. For the 106-1-1100-02 actuator, a torque up to 0.4 m.daN
(35.39 lbf.in) is permitted.
Be careful when you come to the mechanical stop at the end of travel. If you turn the manual override device with a torque more than the limit, damage to the air-intake flap actuator will occur.
NOTE : For the 43-1-1100 Amendment 1 actuator, approximately 47 turns
____ are necessary on the manual override device for one full travel of the air-intake flap actuator. For the 106-1-1100-02 actuator, approximately 87 turns are necessary on the manual override device for one full travel of the air-intake flap actuator.
(3)
Put the air-intake flap actuator (6) in position and install the bolt (5), the washers (3) and (4) and the castle nut (2).
(4)
TORQUE the castle nut (2) to between 0.7 and 0.8 m.daN (61.94 and
70.79 lbf.in) and safety it with a new cotter pin (1).
(5)
Seal the connection with the SEALANTS (Material No. 09-016) and apply PAINTS FOR DETAIL (INTERNAL AND EXTERN AL) (Material No. 07-001).
