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. 3-49 SEE DETAIL A SOFT JAWS WIRE ROPE SEIZING BROOMED WIRE ROPE INSTALL BENT END OF TUBE AWAY FROM DRILL. (SEE NOTE) 44 3"  (LENGTH OF BEND) BENT TUBE PUSH TUBE ON AND PULL OFF EACH WIRE (ONE TIME ONLY) WITH DRILL SPEED AT ANY RPM BETWEEN 450 RPM MINIMUM TO 700 RPM MAXIMUM FOR A PERIOD OF 2 TO 5 SECONDS PER STRAND. DIRECTION OF DRILL DETAIL A NOTE IF DIFFICULTY IS ENCOUNTERED IN STRAIGHTENING THE INDIVIDUAL WIRES IT IS SUGGESTED THAT THE LENGTH OF THE BEND IN THE BENT TUBE BE SHORTENED TO 2 1/4" FROM 3" ABEf0348 VISE Figure 3-48.—Straightening individual wires with power straightening device.
