2-15. Drive Link.
2-16. Inspect drive link as follows:
a. Perform nondestructive test in accordance
with table 2-1.
b. Inspect bushing (47, figure 2-1) in trun-
nion tang of drive link (5), for excessive wear.
ID of bushing must not exceed 0.3140 inch. In-
spect for scoring of inside surface of bushing.
Check dimension between trunnion tangs and
between bushings. If dimension between trun-
nion tangs is greater than 1.003 inch, scrap
drive link. If dimension between bushings is
greater than .880 inch, replace bushings.
c. Inspect bushings (46) in scissors tang of
drive link (5), for excessive wear. Allowable ID of
bushings must not exceed 0.5014 inch. Inspect for
scoring of inside surface of bushing.
d. Inspect drive link (5) for mechanical or
corrosion damage.
(1) Mechanical damage must not exceed
0.010-inch depth in area within 1.25 inches of
centerline of either the trunnion or the scissors
attachment tangs.
(2) Corrosion damage must not exceed
0.005-inch depth in area within 1.25 inches of the
trunnion or the scissors attachment tangs.
(3) Mechanical damage must not exceed
0.035 inch in depth in ail areas of drive link other than
specified in (1) above.
(4) Corrosion damage must not exceed
0.017 inch in depth in all areas of drive link other than
specified in (2) above.
(5) Mechanical or comosion damage in any
one area must not exceed 0.25 square inch in area or
0.75 in any one length.
(6) Mechanical damage to surfaces sur-
rounding a hole within 1.5 times radius of that hole
must not exceed 0.010 inch in depth.
(7) Corrosion damage to surfaces sur-
rounding a hole within 1.5 times radius of that hole
must not exceed 0.005 inch in depth.
(8) Score marks on inside surface of holes
or bushings must not exceed 0.002 inch.
