TM 1-1500-204-23-1 NOTE • Breakage  usually  occurs  in  that length of a cable normally passing over a pulley or through a  fairlead,  as  shown  in  figure  9- 20. • Any   cable   not   within   specified allowable   limits   listed   in   table shall be considered unserviceable and must be replaced. • In  addition  to  limits  specified  in table  9-1  the  maximum  allowable number of broken wires shall not occur    in    any    two    consecutive inches   of   cable,   that   is,   if   six wires are broken in one inch of a 7   x   19   cable,   none   would   be allowed  in  the  next  consecutive inch   For   any   flexible   cable,   a maximum of three broken wires per inch shall be allowable in the length   of   cables   passing   over pulleys, drums, or through fairleads. (b) Replace badly worn cables even if number of broken wires is less than specified for replacement. Figure 9-20.  Typical Breakage Point NOTE • Any 7x7 cable having three wires or  less  per  inch  worn  not  more than   halfway   through   the   wire diameter,   or   any   7   x   19   cable having six wires or less per inch worn    not    more    than    halfway through   wire   diameter,   shall   be considered  serviceable  if  broken wires   are   present   in   the   worn area. • The   cable   shall   be   considered serviceable   if   broken   wires   are present  but  are  not  in  the  worn area. • One  less  worn  wire  per  inch  is allowed    for    each    broken    wire present  in  the  same  inch  if  more than one worn area is found, but all are within specified limits, the cable is satisfactory, provided no two    worn    spots    are    adjacent circumferentially. • Any wire worn completely through,   or   worn   to   a   point   of breaking,    shall    be    considered unserviceable. • Kinked,    twisted,    or    birdcaged cables must be repaired or replaced. • Wear  will  normally  extend  along the  cable  equal  to  the  distance the  cable  moves  at  that  location Wear  may  occur  on  one  side  of the   cable   only   or   on   its   entire circumference. • Replace cables when the individual   wire   in   each   strand appears  to  blend  together  (outer wire  worn  40  to  50  percent)  as depicted   in   figure   9-19.      Actual instances  of  cable  wear  beyond recommended point are shown in figure 9-21. (c)    Move    surface    controls    of    the particular cable to the extremities to reveal the cable in the pulley contact, fairlead area, or drum. 9-17
