Install the 1 x 7½ or the 1¼ x 9½ eye-
bolt (1) Figure 3, in the mounting bracket at the

Bolt the center brace bar (3) and wing
brace bar (5) to the front of the center frame
and wing frame with ¾ x 2 hex bolts (4) with
lock washers and hex nuts. Do not tighten
bolts. Use a 1 x 6 hex bolt (6) and nylon lock
nut in the hinge. Draw nut tight but do not
torque. Tighten all other bolts evenly to
prevent bind at hinge.

(11) with lock washer and hex nuts. The front
bracket uses a ¾ x 5 bolt (12) to attach the
outer end. The rear bracket uses four 5/8 x 1½
bolts (13) with lock washers and hex nuts to
attach the outer end. Bolt the inside hinge (14)
to the wing brace using 5/8 x 1½ bolts (15) and
one 5/8 x 3 x 5½ u-bolt (16) with lock washers
and hex nuts. On model 6542, bolt the 4” K-
Flex stub (17) to the wing frame using 1/2 x 5½
bolts (18) with lock washers and hex nuts.
