(3)
If actuating force is not within specified limit, vary number of washers under base of shear pin to obtain required force. Adding washers will increase force; removing washers will decrease force. (See figure 501.)
(4)
Actuate safety latch to latched position.
(5)
Close and latch tailpipe fairings.

C. Tension Latches Adjustment
(1)
Check that tailpipe fairings are closed and latched.
(2)
Open one latch and check force required to close latch. Latch should close with a force of 20 (士 5) pounds applied to latch handle with adjacent latches closed.
CAUTION: DO NOT USE TOOLS WHEN CLOSING TAILPIPE FAIRING LATCHES. USE HAND PRESSURE ONLY.
(3)
If closing force is not within specified limits, adjust U-bolt as follows:
(a)
Loosen checknuts as necessary to provide adjustment clearance. (See figure 501.)
(b)
Equally adjust self-locking nuts (counterclockwise to lower closing force or clockwise to raise closing force) as required to obtain closing force within limits.
(c)
Secure adjustment by tightening checknuts.
(4)
Repeat steps (2) and (3) for each tension latch. Ensure adjacent latches are closed when checking closing force of each latch.
(5)
Close and latch tailpipe fairings.
D. Reactivate thrust reverser hydraulic system by removing ground locks from both thrust reverser isolation valves.

TAIL PLUG - INSPECTION/CHECK
1. Tail Plug Inspection
A. Equipment and Materials
(1) Thrust Reverser Isolation Valve Ground Lock Cap and Pin Assembly – F80109-3 or F80109-9 or equivalent.
B. Examine Tail Plug
(1)
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 AFTER INSTALLING GROUND LOCKS. REVERSERS SHOULD NOT DEPLOY.
(2)
Examine body of tail plug for cracks. Cracks are allowable through a total of 50 percent of the circumference of the cone. No single crack should exceed a total of 25 percent of the circumference.
(3)
Check for cracks in the tail plug mounting flange. Cracks in the vicinity of the mount holes with a maximum length of 2 inches and affecting not more than four mount holes are allowable. If two consecutive mount holes are affected, there must be two unaffected holes on either side.
(4)
Reactivate thrust reverser hydraulic system by removing ground locks from both thrust reverser isolation valves.

THRUST REVERSER LINKAGE ASSEMBLY - REMOVAL/INSTALLATION
1. General
A. This section covers the removal and installation procedures for the driver links, idler links, overcenter links, guide rods and guide carriage. Access to the linkage is gained by removing the actuator housing fairing.
2. Equipment and Materials
A. Lubricant -MIL-G-81322
B. Thrust Reverser Isolation Valve Ground Lock Cap and Pin Assembly - F80109-3 or F80109-9
3. Prepare for Removal
A. Place deflector doors in the reverse thrust position (Ref. 78-32-01).
WARNING: PERSONNEL MUST STAY CLEAR OF THE THRUST REVERSER WHEN IT IS ACTUATED, TO PREVENT BEING CAUGHT BY ROTATING DEFLECTOR DOORS.
B. Deactivate the 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 screws attaching actuator housing fairing to thrust reverser, and remove fairing.
4. Removal/Installation Driver Links
A. Remove Driver Link
