Connector Contact Pins - Continued
Check the connector to be certain that the new contact is alined with the adjacent contacts.
Section III. SAFETY WIRING TECHNIQUES
Safety Wiring Procedures.
Basic Procedures. The following basic procedures should be followed when installing safety wire.
Safety wire must be tight after installation to prevent failure due to rubbing or vibration.
Safety wire must always be installed so that it tends to tighten the part, thereby counteracting the natural
tendency of the part to loosen. Determine whether the part tightens when turned to the right or to the
left, as this governs the direction in which safety wire is to be threaded through the safety hole. Figure
6-22 illustrates typical methods for safety wiring of right-hand threaded parts. Use the reverse
procedure for left-hand threaded parts.
Safety wire must never be overstressed. When tightening the safety wire, twist it enough to insure the
securing of the part, but not so much that the wire becomes stressed to a point where it will break under
a slight load.
Handle safety wire during installation so that the strands do not become kinked, nicked, or flattened.
Avoid pulling the wire around square corners or gripping it too tightly with tools.
Make certain safety holes are exposed as much as possible and that parts are properly tightened before
installing safety wire. However, parts should not be loosened or torqued beyond the specified values in
order to improve the location of safety holes. Do not use or drill unspecified safety holes.
Never twist the wire ends off with pliers. Cut the ends square to eliminate sharp points, leaving from
three to six turns after the loop. Do not allow cut off ends to fall into the parts being safety wired.
Safety wire ends must be bent in toward the item being safety wired to prevent possible injury to the
Safety wire must never be reused.
Use double safety wire (fig. 6-22) in all cases except for emergency equipment.
