Installing the Wing Box Frames
Refer to Figure 1-6:
Unfold the wing toolbars (#1) until they contact the center
box frame. Remove the horizontal toolbar pivot pins (#2)
from the wing box frames and position a wing box frame
pivot to line up with the pivot tube on the wing toolbar. In-
stall the pivot pin (#2) from the front (with the taper pointing
back) placing one 1/4" thick thrust washer (#6) on each
side of the toolbar pivot. Assemble a 1 1/4" flat washer
(#3), and 1 1/4" hex slotted nut (#4) on the back side of the
pin. Torque this rear nut to 600 ft-lbs to properly seat the
pin into the taper before proceeding with the assembly.
Use the cotter pin hole on the front end of the pin to keep
it from rotating while you tighten the rear nut. After torqu-
ing to 600 ft-lbs, secure the nut with a 5/16" x 2 1/2" cotter
pin (#5) by rotating the slot in the nut to the next available
cotter pin hole in the pin. There are two cross holes so the
slot in the nut should align with a hole with less than 1/12
additional rotation of the nut. Install the large hinge washer
(#7), the 1 1/4" flat washer (#3), and the 1 1/4" slotted nut
(#4) on the front side of the pin. Torque the front 1 1/4" slot-
ted nut to 400 ft-lbs and assemble the 5/16" x 2 1/2" cotter
pin (#5) in the next available cross hole.
NOTE: Torquing the rear nut (on the tapered end of the
pin) is easiest when the opener frames are lowered.
You may wish to wait until the hydraulics are charged
and the openers are lowered before torquing the hori-
zontal pin 1 1/4" nuts. Always torque the rear nuts be-
fore drawing up the front nuts
