Install the Locking Hydraulic Actuator (Fig. 401 and 402)
S 864-030-N00
(1)
Make sure the DO-NOT-OPERATE tags are installed on the forward thrust levers and the reverse thrust levers.
S 864-031-N00
(2)
Make sure the thrust reverser sleeve is extended approximately 1.0 inch (approximately 25.0 mm) or less from the fully stowed position.
S 224-088-N00
CAUTION: DO NOT PERMIT THE ROD END TO TURN WHEN YOU ATTACH IT TO THE
_______ THRUST REVERSER SLEEVE. IF THE ACTUATOR ROD END TURNS, YOU CAN CAUSE DAMAGE TO THE THRUST REVERSER OR THE ACTUATOR WHEN YOU OPERATE THE THRUST REVERSER.
(3) Do these steps to make sure the center locking actuator is fully retracted before you install it:
(a) Measure the clearance between the rod end collar and the actuator cylinder (dimension A in Fig. 401).
NOTE: Dimension A must be 0.010 - 0.018 inch (0.254-0.457 mm)
____ when the actuator is fully retracted. If the actuator is not in the specified limits, replace the actuator or adjust the actuator rod end. The actuator rod end is adjusted to make sure the end of the stop bracket slot does not prevent the movement of the feedback stop bolt.
