LINKAGE RETAINING DEVICES, MISSING
Most linkages have retainer devices, cotter keys, lacing wire, or safety pins, to keep the connecting bolts or pins in place.
During BDAR repairs, small pins may become lost or forgotten which will cause linkage or component failure.
Repairing
the vehicle by securing connecting bolts or pins can be accomplished using wire, welding rod, bolts, or nails.
Slotted nuts
can also be retained using this method.
Alignment pins or dowels can be replaced with cut bolts.
