B.  Skydrol Assembly Lube - MCS 352 or Fire Resistant Hydraulic Fluid - BMS 3-11
3.  References
A.  AMM 29-11-00/201, Hydraulic System A
B.  AMM 29-12-00/201, Hydraulic System B
4.  Remove the Hydraulic Fuse (Fig. 401)
A.  Depressurize the hydraulic systems (AMM 29-11-00/201 and 29-12-00/201).
B.  Disconnect the inlet and outlet hydraulic tubes from the hydraulic fuse.
C.  Remove the hydraulic fuse.
D.  Install the protective caps and plugs on all the hydraulic tubes.
5.  Install the Hydraulic Fuse (Fig. 401)
A.  Remove the reducer from each end of the used fuse and install them on the new fuse.
B.  Apply hydraulic fluid or assembly lube to the new O-rings and install O-rings on the reducers.
C.  Place the fuse in position and make sure the flow direction arrow points forward.
CAUTION:  MAKE SURE THE FLOW DIRECTION ARROW ON THE FUSE POINTS FORWARD (SEE DECAL ON AIRPLANE). IF THE FUSE IS INSTALLED INCORRECTLY, ASYMMETRIC EXTENSION OF THE THRUST REVERSER CAN OCCUR.
CAUTION:  MAKE SURE THE CORRECT HYDRAULIC FUSE IS INSTALLED FOR THE THRUST REVERSER STANDBY SYSTEM. IF THE INCORRECT FUSE IS INSTALLED, ASYMMETRIC EXTENSION OF THE THRUST REVERSER CAN OCCUR.
D.  Connect the inlet and outlet hydraulic tubes to the hydraulic fuse.
E.  Pressurize the hydraulic systems (AMM 29-11-00/201 and 29-12-00/201).
F.  Make sure there are no leaks at the fuse connections.
G.  Do a test of the thrust reverser operation with the alternate hydraulic system

THRUST REVERSER CONTROL VALVE -REMOVAL/INSTALLATION
1. Equipment and Materials
A. Thrust Reverser Isolation Valve Ground Lock Cap and Pin Assembly - F80109-3 or F80109-9
2.  Remove Thrust Reverser Control Valve
A.  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 DEPLOY THRUST REVERSERS.
B.  Remove wing access panel 6301 on left wing or 6401 on right wing to gain access to thrust reverser control valve (Ref Chapter 12, Access Doors and Panels).
C.  Disconnect control valve link at lever arm (Fig. 401).
D.  Disconnect hydraulic lines (four places) from valve fittings and cap al1 lines. Cap or plug control valve ports.
NOTE 1: To facilitate valve removal, it may be necessary to remove the valve port fittings.
NOTE 2: To facilitate removal of No. 2 engine control valve, place No. 2 thrust lever in full forward position.
E.  Remove control valve mounting bolts and spacers (and washers and nuts, if applicable). Remove valve.
3.  Install Thrust Reverser Control Valve
A.  Position control valve at engine controls mounting bracket on wing front spar and attach to bracket with bolts and spacers (and washers and nuts, if applicable) (Fig. 401).
NOTE:  To facilitate installation of No. 2 engine control valve, place No. 2 thrust lever in full forward position.
B.  Remove caps or plugs from control valve and hydraulic lines and connect hydraulic lines to fittings on valve.
NOTE: If installed, restrictor (section AA) must have shoulder against boss as shown.
C.  Connect valve link to lever arm with screw, washer, and nut. Torque nut 40 to 50 pound-inches.
D.  Replace access panel 6301 on left wing or 6401 on right wing.
E.  Reactivate thrust reverser hydraulic system by removing ground locks from both thrust reverser isolation valves.

THRUST REVERSER SHUTTLE VALVE - REMOVAL/INSTALLATION
Prepare for Removal
A.  Remove hydraulic pressure from the thrust reverser system:
(1)  
Move the landing gear selector lever to the OFF position and install a DO-NOT-OPERATE tag.

NOTE: This will remove the pressure from the main landing gear down line.

(2)  
Depressurize the standby hydraulic system (Ref 29-12-0/201) to remove the alternate hydraulic pressure.
