(4) If dimension A is out of limits, do the steps in AMM 78-31-17/501 Thrust Reverser Hydraulic Actuators -Adjustment/Test
S 864-118-N00
(5) Turn the flexshaft drive to extend the actuator rod end 1.0 inch (25.4 mm), but do not let the actuator rod end turn.
S 424-119-N00
(6) Install the rod end of the actuator (11) through the opening in the torque box, but do not let the actuator rod end turn. (a) Align the hydraulic ports on the actuator with the hydraulic lines.
S 434-120-N00
(7) Install the bolt (5), washers (6), nut (7) and cotter pin (9) to attach the actuator rod end to the thrust reverser sleeve.
(a) (b) (c) Tighten the castellated nut (7) to 20 pound-inches (2.26 newton-meters).Tighten the castellated nut (7) to the next castellation and install the cotter pin (9).Apply BMS 5-63 sealant approximately 0.06 inch (1.524 mm) thick to the nut (7), the cotter pin (9), and the end of the bolt (5).
S 434-035-N00
(8) Install the retainers (2) which attach the gimbal ring to the mounting bracket with the bolts (1) (Fig. 401). (a) Remove the dust cap from the top flex shaft hole on the hydraulic actuator.
CAUTION:_______ BE VERY CAREFUL WHEN YOU TURN THE SQUARE DRIVE KEY. THE SQUARE DRIVE KEY CAN CAUSE DAMAGE TO THE SPLINED FLEX SHAFT HOLE.
(b) To release the actuator lock, turn the lock lever (6) in a clockwise direction to hold the hydraulic actuator unlocked while you turn the square drive key in the subsequent step.

(d)
Release the lock lever (6) to set the actuator lock (Fig. 402).
(e)
Install the retainers (2).
(f)
Measure the distance between the mounting brackets and the gimbal ring.
(g)
Remove the retainers (2).
(h)

(i)
Install the shims (3) between the gimbal ring and mounting bracket at the two locations.
(j)
Install the retainer bolt (1).
(k)
Tighten the retainer bolt (1).
S 434-036-N00
(9)
Remove the protection caps from the retract and extend ports on the locking hydraulic actuator.
S 434-037-N00
(10)
Connect the retract hydraulic lines (2, 5) to each side of the locking hydraulic actuator (11).
(a) Tighten the tube nuts for the retract hydraulic lines (2, 5).
S 434-038-N00
(11) Connect the extend hydraulic line (8).
(a) Tighten the tube nut for the extend hydraulic line (8).
S 434-039-N00
(12)
Tighten the support block fasteners for the hydraulic lines to attach the retract and extend hydraulic lines.
S 434-040-N00
(13)
Make sure the connections for the hydraulic lines (2, 5, and 8) are attached correctly.
NOTE:____The upper and lower flex shaft lines are disconnected. These lines will not be pressurized when you apply the hydraulic power to the system.
(a) If it is necessary, tighten the tube nut(s).
