THRUST REVERSER LINKAGE LUBRICATION
1. General
A. This procedure contains the steps to lubricate the thrust reverser linkages that need lubrication. There are two different linkages for the thrust reverser, the driver link (4 locations) and the idler link (4 locations).
2. Equipment and Materials
A. Flush gun (grease gun)
B. Grease - MIL-G-81322 (AMM 20-30-21)
3. Lubricate the Thrust Reverser Linkages
A. Put the deflector doors in the reverse thrust position (AMM 78-32-01/201).
WARNING: MAKE SURE ALL PERSONS ARE CLEAR OF THE THRUST REVERSER. THE DEFLECTOR DOORS WILL ROTATE AFT WHEN THE THRUST REVERSER IS DEPLOY. THE THRUST REVERSER CAN CAUSE INJURIES TO PERSONS OR DAMAGE TO EQUIPMENT.
(1) Deactivate the reverser hydraulic system:
(a) Install ground locks on both thrust reverser isolation valves.
WARNING: MAKE SURE THE GROUND LOCKS ARE CORRECTLY INSTALLED. MAKE SURE THE THRUST REVERSERS CANNOT DEPLOY AFTER YOU INSTALL THE GROUND LOCKS. ACCIDENTAL DEPLOYMENT OF THE THRUST REVERSERS CAN CAUSE INJURY TO PERSONS OR DAMAGE TO EQUIPMENT.
(2)
Remove the screws that attach the actuator housing fairing to the thrust reverser.
(3)
Remove the actuator housing fairing.
B. Lubricate the thrust reverser links as shown (Fig. 201).
C. Install the actuator housing fairing.
D. Remove the ground lock from both thrust reverser isolation valves.
E. Put the deflector doors in the forward thrust position (AMM 78-32-01/201).
WARNING: MAKE SURE ALL PERSONS ARE CLEAR OF THE THRUST REVERSER. THE DEFLECTOR DOORS WILL ROTATE AFT WHEN THE THRUST REVERSER IS DEPLOY. THE THRUST REVERSER CAN CAUSE INJURIES TO PERSONS OR DAMAGE TO EQUIPMENT.

ACCESS DOORS AND PANELS
1. General
A. This section covers procedures that should be followed generally when an access door or panel is removed and installed.
2. Bonding Jumpers
A. Bonding jumpers disengaged to remove a panel must be engaged again when the panel is installed.
3. Aluminum and Steel Fasteners
A. Care should be taken to distinguish between aluminum and steel fasteners. Unless special attention is paid by personnel to aluminum fasteners, there is a possibility that they will be installed utilizing a torque value normally associated with the same diameter steel fastener which could either stretch the fastener or damage the drive slot or threads.
4. Faying Surface Seals
A. If you break a faying surface seal during panel removal, you must apply a new faying surface seal during the panel installation (AMM 51-31-0/201).
NOTE: Most access panels do not have a faying surface seal. If a panel has a faying surface seal, apply BMS 5-95 sealant if the panel does not touch fuel, and BMS 5-26 sealant if the panel touches fuel (unless other AMM procedures are specified).

ACCESS DOORS AND PANELS -IDENTIFICATION AND LOCATION
1. General
A. Access doors and panels are identified by a four-digit number and in general by a descriptive designation. The first two figures of any identification number are related to a particular zone on the airplane (Fig. 201). The last two digits of any identification number is the number of the panel or door within a zone. Refer to AMM 51-31-0/201 for sealing instructions.
B. Coverage of access doors and panels has been broken down according to the following (Fig. 202).
