1.9.5 Track and undercarriage inspection
The rubber track carcass has many layers of cable, similar to the cables used in automotive tires. The most
important set of cables are located about 8 mm (0.3 in) beneath the inside surface of the track. This set of
cables, called the zero degree cables (1), with stands track tension. Other sets of cables, called the breaker
cables (2) are located between the zero degree cables and the outside surface of the track. The cables are
in dierent angles to give lateral support and to protect the zero degree cables.
