9) With the depth gage, measure the X and Y dimensions. Y dimension must be equal to :
Y = X [- .02 ; + 0 in (- 0.5 ; + 0 mm)]
NOTE : Under no circumstances, should Y dimension be longer than X one, should it be the case, a misalignment toward the top of the smooth pin (3) and a tendency to the unlocking of the strut would result.
10) Check with a depth gage that the play (C) is less than or equal to 0.002 in (0.05 mm) between roller (9) and the rear bearing surface of hook (8).
11) Be sure of an overlap (A) between 0.22 in (5.5 mm) and 0.25 in (6.3 mm) between hook (8) and front half-leg (2).
12) If one of the 3 dimensions is not complied with, refer to Paragraph C.
13) After adjustment, install the hinged strut - refer to Paragraph 2.  14) Adjust the microswitch - refer to 32-30-07.

WARNING : IT IS MANDATORY TO OBTAIN THE THREE DIMENSIONS. IF ONE, TWO OR THE THREE DIMENSIONS CANNOT BE OBTAINED, CHANGE THE DEFECTIVE DETAIL PART(S) AND CHECK THE THREE DIMENSIONS AGAIN.
1) If Y dimension is above or equal to X dimension, adjust with the Geneva file then with abrasive cloth (TB 05-916B) the bearing surface (B) of the front half-leg (2) on the roller (9). Make it moderatly, take care to the perfect spotfacing of the bearing surface (B) and the radius (R) maintain of .02 in (.5 mm) allowing a better hook sliding on the front half-leg when locking.
2) If the overlap dimension (A) is less than 0.22 in (5.5 mm), rework with the Geneva file then with abrasive cloth (TB 05-916B) the bearing surface of the front half-leg (2) in contact with the hook (8). Make sure to maintain the parallelism between the half-leg (2) bearing surface and hook (8) bearing surface.
