4. Install Thrust Reverser Actuators
A. Apply thin film of lubricant to actuator bearing.
B. Remove plugs from actuator ports and position actuator inside shroud assembly box (Fig. 401).
C. Attach actuator to support bracket with bolt and washer. Torque bolt to 450-500 pound-inches.
D. Attach actuator rod to guide carriage with bolts, washers and nut. Torque to 160-190 pound-inches.
E. Position hydraulic lines on thrust reverser and connect lines to actuator ports.
F. Remove caps from hydraulic lines and connect forward end of stow line to tee and forward end of deploy line to union. Torque fittings to 260-280 pound-inches.
G. Install feedback control rod per 78-34-32.
H. Reactivate thrust reverser hydraulic system by removing ground locks from both thrust reverser isolation valves.
I. Cycle thrust reverser through 5 cycles to remove entrapped air from hydraulic lines and actuators. Check for leaks.
WARNING: PERSONNEL MUST STAY CLEAR OF THE THRUST REVERSER WHEN IT IS ACTUATED TO PREVENT BEING CAUGHT BY ROTATING DEFLECTOR DOORS.
J. Check thrust reverser rigging per 78-32-01.
K. With deflector doors in reverse thrust position, deactivate thrust reverser hydraulic system by installing ground locks in both thrust reverser isolation valves.
WARNING: SERIOUS INJURY CAN RESULT TO PERSONNEL IF GROUND LOCKS ARE NOT PROPERLY INSTALLED. ATTEMPT TO RETURN THRUST REVERSERS TO FORWARD THRUST AFTER INSTALLING GROUND LOCKS. REVERSERS MUST NOT MOVE HYDRAULICALLY.
5. Restore Airplane to Normal
A. Position upper panel on shroud assembly box and attach with bolts and washers. Torque to 50-70 pound-inches.
B. Attach actuator housing fairing to thrust reverser with screws.
C. Install lower access panel.
D. Reactivate thrust reverser hydraulic system by removing ground locks from both thrust reverser isolation valves.

B. Thrust Reverser Isolation Valve Ground Lock Cap and Pin Assembly - F80109-3 or F80109-9 or equivalent
2. Prepare for Removal
A. Place deflector doors in the reverse thrust position per 78-32-01.
WARNING: PERSONNEL MUST STAY CLEAR OF THRUST REVERSER WHEN IT IS ACTUATED TO PREVENT BEING CAUGHT BY ROTATING DEFLECTOR DOORS.
B. Deactivate thrust reverser hydraulic system by installing ground locks on both thrust reverser isolation valves.
WARNING: SERIOUS INJURY CAN RESULT TO PERSONNEL IF GROUND LOCKS ARE NOT PROPERLY INSTALLED. ATTEMPT TO RETURN THRUST REVERSERS TO FORWARD THRUST AFTER INSTALLING GROUND LOCKS. REVERSERS MUST NOT MOVE HYDRAULICALLY.
C. Remove access panel.
3. Remove Thrust Reverser Lock
A. Disconnect hydraulic lines from actuator and cap lines. (See figure 401.)
B. Remove union fittings from actuator ports.
C. Remove screws attaching proximity switch to latch support and remove switch.
D. Remove screws, nuts and washers securing forward end of lock assembly to shroud.
E. Remove screws, nuts, and washers securing aft end of lock assembly to shroud assembly bulkhead.
F. Remove lock assembly from thrust reverser.
