7 . There are two holes in the reverse
adjustable link (S, Figure 5-15). Push
inward on the reverse idler arm (K) and
install the clevis pin (R) through the inner
hole in the reverse adjustable link (S) and
out through the single hole in the reverse
idler arm (K). Secure the clevis pin with
the hairpin cotter.
8 . Reinstall the reverse belt (P, Figure 5-13)
on the reverse (upper) pulley, making
sure the belt is located to the inside of the
reverse idler pulley (L, Figure 5-13).
9 . Reinstall the belt cover and secure it
with the two nuts.
IMPORTANT: If, in future tests for
reverse belt tension, the guide mark
should again align with or move to the
right side of the guide pin, it means that
the reverse belt is worn beyond adjust¬
ment. Before installing a new belt, you
must return the clevis pin to the OUTSIDE
hole in the reverse adjustable link.

hole of reverse adjustable link.
