(8) Hold two bolts (32). Use socket.
(9) Torque two nuts (31) to 225 INCH-POUNDS.
Use torque wrench, crowfoot, and adapter.
(10) Laterally center stabilator (2) so that gaps
between pivot lugs (38) and (37) are equal
within 0.010 INCH on both sides of helicopter.
(11) Measure gaps under flanges of two spacers
(34) and faces of mating angles (42).
(12) Go to 2.113.3.e. to remove two nuts (31),
washers (33).
(13) Measure thickness of two shims (35). Re-
quired shim (35) thickness is 0.001 INCH to
0.003 INCH less than measured gap in step
a.(11). Peel shim leaves or replace shims and
peel off layers to meet gap requirement, if

POUNDS.
(1) Hold two bolts (32). Use open end wrench.
(2) Torque two nuts (31) to 1100 INCH-
POUNDS. Use torque wrench, crowfoot, and
adapter.
(3) Increase torque to aline cotter pin holes, but
