Detail Steps/Work Items
Key Items/References
(1)
Pull the wire through the first bolt.
(2)
Bend one end of the wire around the head of
the bolt [1] to bolt [2].
The direction must be such that
when you pull the twisted wire to the
bolt [2], this will cause the bolt [1] to
tighten.
(3)
Twist the outer wire under the other wire near
to the bolt [1].
Refer to Fig. 70 - 4.
(4)
Continue to twist the wire clockwise.
Keep the strands apart to twist the
wire tight even.
(5)
When the twisted pair touches the bolt [2]
without tension, put the wire in the bolt hole.
The direction must be such that
when the bolt [2] begins to loosen, it
will pull the first bolt tight.
(6)
Bend the free wire around the head of the bolt
[2].
Refer to Fig. 70 - 4.
(7)
Twist the wires counterclockwise.
Twist the wires beyond the bolt to
make a pigtail.
(8)
Cut the pigtail square.
Keep a minimum of three twists.
(9)
Bend the pigtail over against the part being
safety wired to prevent it from becoming a
snag.
(10)
Remove the cut-off ends.
Make sure that no debris enters the
engine by any opening.
