Make certain that the large seizing is tight; remove
the copper wire seizing from one strand at a time, and
straighten the individual wires, using the power
straightening device, shown in figure 3-48.
Repeat the straightening procedure on each strand,
working on one strand at a time, until all the wires are
completely broomed out as shown in figure 3-48.
Cleaning Wire Rope and Terminal Pouring
The cleaning and preparation of wire rope and
terminals requires the use of chlorinated degreasing
solvents, grit blasting, and the heating and melting of
zinc.
WARNING
Personnel cleaning wire rope and pouring
terminals must use chemical respirators and
make sure the area is properly ventilated. For
complete safety procedures concerning zinc
terminal pouring and wire rope preparation,
consult the current arresting gear NAVAIR
operation,
maintenance,
and
overhaul
instructions.
In a well-ventilated space, prepare the ultrasonic
degreaser unit by filling it with GRISOLVE PEG-2, to
within 1 inch of the tank top. The ultrasonic degreaser
must then be energized for 2 hours before degreasing
operations begin; this degasses and removes oxygen
from the solvent, which increases its cleaning ability.
One hour before the degreasing operation is to start,
turn on the ultrasonic unit's heaters to heat the
GRISOLVE PEG-2 to a temperature of 90 to 100°F. A
stainless steel bucket (14-quart) will also be filled with
3 gallons of GRISOLVE PEG-2; this is used to rinse the
broomed cable end after it has been cleaned in the
ultrasonic degreaser unit.
