(f)
To find the total free movement, subtract the dimension Z from the dimension Y.
(3)
At the track 3 position, measure the total free movement of the actuator lever (dimension X):
(a)
Apply a down force (by hand) to the actuator lever. Apply sufficient force to make the actuator lever move through possible free movement in the flap system mechanism and joints.
(b)
Hold the actuator lever in this position, then measure and record the dimension T.
(c)
Apply an up force (by hand) to the actuator lever. Apply sufficient force to make the actuator lever move through possible free movement in the flap system and joints.
(d)
Hold the actuator lever in this position, then measure and record the dimension S.
(e)
To find the total free movement (dimension X), subtract the dimension S from the dimension T.
(4)
Install the aluminum pin through the joint where you removed the bolt (226).
(5)
Retract the flaps fully (Ref. TASK 27-50-00-866-009).
(6)
Remove the aluminum pin.

(7)
At the track 3 position, temporarily connect the flap drive arm to the rotary actuator drive-lever as follows:
(a)
Install the bolt (226), the washer (229) and the nut (230).
(b)
Hand tighten the nut (230).
(8)
At the track 4 position, disconnect the outboard flap drive-arm from the rotary actuator drive-lever:
(a)
Remove and discard the cotter pin (231).
(b)
Remove the nut (230) and the washer (229).
(c)
Remove the bolt and install the aluminum pin (10.0 mm (0.3937 in.) diameter).
(d)
Extend the flaps fully (Ref. TASK 27-50-00-866-008).
(e)
Remove the aluminum pin.
(9)
At the track 3 position, measure the total free movement of the flap trailing edge:
(a)
Make sure that the flaps are fully extended, and that the travel ranges are clear.
(b)
Apply a down force (by hand) to the trailing edge of the flap. Apply sufficient force to make the flap move through possible free movement in the flap system mechanism and joints.
NOTE : Do not apply too much force to cause the system
____ components, mechanism or the aircraft fixed structure to move or bend.
(c)
Hold the flap in this position, then measure and record the dimension Z.
(d)
Apply an up force (by hand) to the trailing edge of the flap. Apply sufficient force to make the flap move through possible free movement in the flap system mechanism and joints.
NOTE : Do not apply too much force to cause the system
____ components, mechanism or the aircraft fixed structure to move or bend.

(e)
Hold the flap in this position, measure and record the dimension Y and then release the flap.
(f)
To find the total free movement, subtract the dimension Z from the dimension Y.

(13)
Remove the aluminum pin.
(14)
At the track 4 position, temporarily connect the flap drive arm to the rotary actuator drive-lever as follows:
(a)
Install the bolt (226), the washer (229) and the nut (230).
(b)
Hand tighten the nut (230).
