(3)
Lockwire must never be overstressed. It
will break under vibration if twisted too tight on
installation. The lockwire should be pulled taut when
being twisted, but should have minimum tension, if any,
when secured.
(4)
Lockwire ends must -be bent, after
cutting, toward the engine or part, to avoid sharp or
projecting ends which may present a safety hazard or
vibrate in the airstream.
(5)
Internal lockwiring must not cross over or
protrude into flow passages when an alternative wiring
method can be used.
(6)
Before installing lockwire, confirm that all
parts of components to be lockwired are correctly
torqued and that the associated wiring holes are
positioned correctly with respect to each other. When
there are two or more parts, it is desirable that the holes
in the parts be in the same relative positions.
CAUTION
Parts must never be overtorqued or
loosened
to
facilitate
correct
alignment. It should however, be
possible to obtain correct alignment
within the specified torquing limits for
the part. If it is not possible to obtain
correct alignment within specified
torque limits, remove part and install
replacement.
(7)
To prevent damage to twisted portion of
wiring, when using pliers or twisting device, grasp wire
at the ends or at a point on wire which will not be
twisted.
CAUTION
Lockwire must not be nicked, kinked
or damaged in any form. Never twist
the wire ends off with pliers, and when
cutting off surplus, insure at least
three complete turns remain after
locking part. Insure no surplus
lockwiring falls into engine. The
strength of lockwire holes on parts is
marginal; therefore, when removing
lockwire, never twist wire off to
remove; always cut.
