Update Wing Pivot Anti-Rotation
Refer to Figure 63
If the existing pins are undamaged, leave the wing pivot
pins
in place for this update.
Pinch / Crush Hazard:
If the existing pins must be removed, follow instructions care-
fully. Remove only one pin at a time. Begin inserting a second
pin before the first is fully removed. Without use of additional
hoists and supports, an un-pinned wing can move or fall,
which could result in injury and equipment damage.
Start with the LH rear pivot.

Use one of the new pins to drive the old pin
out. Then use the second new pin to drive the
first new pin back out, with this second new pin
replacing the damaged old pin as originally
installed.
223. Select one new:
160-811D WING HINGE PIN ROTATION STOP
224. Place the stop around the pivot shaft cap of the
new or existing pin ( or ). On the pivot exten-
sion, mark around the outer edge of the stop for
paint removal. Remove paint in preparation for
welding.
