(b) External Wear Patterns
Wear will normally extend along cable equal to the distance cable moves at that location.
Wear may occur on one side of the cable only or on its entire circumference. Replace
flexible and non-flexible cables when individual wires in each strand appear to blend
together (outer wires worn 40-50 percent) as depicted in Figure 3-23.
(c) Internal Cable Wear
As wear is taking place on the exterior surface of a cable, the same condition is taking
place internally, particularly in the sections of the cable which pass over pulleys and
quadrants. This condition, shown in Figure 3-24, is not easily detected unless the strands
of the cable are separated. Wear of this type is a result of the relative motion between
inner wire surfaces. Under certain conditions the rate of this type wear can be greater than
that occurring on the surface.
