(b) If the Thrust Links Were Kept with the Engine (alternate method, install the thrust link assembly on the strut as follows: 1) Apply the antiseize compound to the wedge surfaces of the
thrust fitting.
2) Apply the antiseize compound to the threads of the five bolts (5) that attach the thrust link assembly to the strut.
3) Put the thrust fitting onto the lower surface of the strut and install the bolt (5) and washer (6) in the center. 4) Tighten the bolt until the wedges of the thrust fitting and the strut engage. 5) Install the four outer bolts (5) and washers (6) until the washers touch the thrust fitting. 6) Do a check of the barrel nuts for self-locking torque. a) Apply a minimum torque of 18 pound-inches (2 Newton meters) on the nut.
NOTE: Apply only the minimum torque to prevent worn
____ threads. It is not necessary to calculate the breakaway torque.
b) If you cannot get the minimum torque, replace the barrel nuts and examine the bolts for worn threads. 7) Tighten the five bolts (5) to 585-715 pound-inches (66-81 Newton meters).
NOTE: Keep a constant clearance between the thrust
____
fitting and the strut.
