_______
R Safety cable is an alternative to safetywire. Safety cable is installed
R through two or more parts in such a way that as the fastener or part
R loosens the safety cable will tighten. When the safety cable tightens it
R will not permit the fastener or part to turn.
R The cable process uses two parts:
R - a cable with a fitting already crimped to one end,
R - a ferrule to set.

R (1) General recommendations and Typical Locking Method.
R (Ref. Fig. 203/TASK 70-22-00-991-302)
R (2) Safety cable (Material No. CP8006) is available in one size, 0.032
R in. (0.8mm).
R When the safety cable is installed the ferrule will be crimped on the
R open end of the cable.
R (3) The hand operated crimping tool comes in different lenghts. The
R crimping pressure of the tool is set by the manufacturer. The primary
R parts of the crimping tool are the crimping head, tensioning wheel,
R slotted wheel and handles. This tool is used to crimp the ferrule on
R the end of the safety cable. The Crimping tool will cut the safety
R cable even with the ferrule at the same time the ferrule is crimped.
R (4) The Hydraulic tool operates in one direction only and has a cycle end
R dead stop to tell the operator when the ferrule is fully crimped. The
R crimping pressure of the tool is set by the manufacturer. If
R necessary, the crimping pressure can be adjusted with standard hand
R tools. The snap-on tool has a spring loaded crimp rod to hold the
R ferrule in place during the crimping procedure. Cable tension is done
R automatically by the internal retraction mechanism.
R (5) Bergen process (Safety cable)
R CAUTION : SAFETY CABLE MUST NOT BE USED INSIDE OIL SUMPS OF ENGINE
_______ R (FWD AND AFT) AND INSIDE AGB AND TGB CONTAINING BEARINGS R AND GEARS.
R (a) Do not install safety cable in such a way as to cause the wire to R be subjected to chafing, fatique through vibration, or additional R tension other than the tension imposed on the wire to prevent R disengagement.
R (b) In all cases, safety cable must be installed through the holes R provised. When no holes is provided, attach the safety cable to a R neighboring part so as not to interfere with the function of the R parts, and in accordance with the recommendations. R (Ref. Fig. 203/TASK 70-22-00-991-302)
R (c) The maximum span of safety cable cable between tension points R shall be 6 in. (152.4 mm), unless otherwise specified. Where R several fasteners form a group to be safetywired together, the R maximum number of units in a series shall be limited to the R number of units that can be safetywired by a 24 in. (609.6 mm) R length of cable.
