a. Repair
(1) Restitching. Restitch broken or loose stitching according to original construction details using the
specifics of paragraph 2-19.
(2) Restencil. As required, restencil identification marks using the procedures of paragraph 2-21.
(3) Retacking. Retack the buffer on the clevis attaching loop end of a riser at each of the original three
tacking points using one turn double, ticket No. 5 waxed cotton thread at each point. Secure the tacking ends
at each point with a surgeon's knot and a locking knot. Trim tie ends to ¼ inch.
(4) Replacing a clevis attaching loop buffer. Replace a damaged clevis attaching loop buffer by
fabricating as follows:
(a)
If applicable, remove the attaching loop from the suspension clevis.
(b)
Remove the original buffer from the clevis attaching loop by cuffing the tacking which
secures the buffer within the loop.
(c)
Cut an 8 ¾ -inch length of 1 ¾ -inch wide, type VIlI cotton webbing and wax the ends.
(d)
Double the webbing length and align the ends. At a point ¼ inch back from the aligned
ends, secure the webbing ends together by stitching two rows laterally across the webbing
width. Stitching will be made with a light-duty sewing machine, using size E nylon thread, 7
to 11 stitches per inch (figure 2-126).
