removed. 2) The two aft upper compression pads , at NAC STA 233.38 and NAC STA 246.70 on each thrust reverser half.
(c)
Apply bearing grease to the surfaces (or other suitable release agent) which will contact with the clay when the cowl/reverser halves are closed.
WARNING: OBEY THE INSTRUCTIONS IN THE PROCEDURE TO CLOSE THE THRUST
_______ REVERSERS. IF YOU DO NOT OBEY THE INSTRUCTIONS, INJURIES TO PERSONS AND DAMAGE TO EQUIPMENT CAN OCCUR.
(d)
Close the thrust reverser (AMM 78-31-00/201).
(e)
Make sure that the V-blade and groove surfaces on the extension ring of the fan frame and reverser are fully engaged.
(f)
Close all five latches.
NOTE:____Starts at the forward latch and continues to aft. Use a 50 to 55 pounds (22.7 to 25 kg) closing force as measured one inch (25.4 mm) from latch handle end. If it is necessary, use the hex key wrench to turn the adjustment screw, installed in the end of latch hook, to get the correct closing force.

(49) Adjust the compression rods as follows (Fig. 404) for these items:
(a) The forward compression rod location NAC STA 233.38. 1) Add the left and right clay thicknesses. 2) Subtract two times the necessary distance of 0.03 to 0.06
inch per side (0.76 to 1.52 mm). 3) The difference is the length that it is necessary to increase the compression rod by. 4) Loosen the jamnut and turn the compression rod pad to make the rod longer.
NOTE: One full turn have the same value as 0.056 inch
____
(1.42 mm).
Example: Clay thickness left side 0.11 inch (2.79 mm) (plus) + Clay thickness right side +0.08 inch (2.03 mm) -------------------
0.19 inch (4.82 mm)
(minus) - 2 X gap requirement -0.06 inch (1.52 mm) -------------------
0.13 inch (3.30 mm)
Increase the compression rod length 0.13 inch (3.30 mm).
5) Tighten and lockwire the jamnut to the compression rod body, then lockwire the rod pad to the jamnut.
(b) The aft compression rod, location NAC STA 246.70. 1) Add the left and right clay thicknesses. 2) Subtract two times the necessary distance of 0.03 to 0.06
inch per side (0.76 to 1.52 mm). 3) The difference is the length that it is necessary to increase the compression rod by. 4) Loosen the jamnut and turn the compression rod pad to make the rod longer.
