5.19.2 Checking the Rubber Tracks
The structure of the rubber track is shown in
Figure 37. The steel cables (1) and metal core (2)
are embedded in the rubber.
Inspect the tracks for damage (Table 10).
Track damage may be classified as either
Terminal or Cosmetic.
Any breakage of the steel cables or metal cores is
considered Terminal and the track should be
replaced.
Figure 37 - Rubber Track Structure
All other forms of damage are initially considered to be Cosmetic, but the effects of
Cosmetic damage are cumulative, eventually leading to replacement of the track.
If the metal cores become exposed for more than half of the circumference of the track,
replacement should be considered.
Damage Probable Cause
Breakages of steel cables and metal
cores.
(Terminal - replace track)
Excess track tension, caused by:
Build up of stones or foreign matter between track and frame.
Track slipping off its guide system.
Extreme friction such as rapid changes of direction.
Improper contact between the track and the sprockets.
Operation on sandy terrain.
Cracks at the base of the carved
profiles.
Rubber fatigue due to bending.
Cracks and bends on the edge of the
rubber.
Manoeuvring on concrete edges and kerbs.
Cracks and abrasions in the rubber on
the guide roller paths.
Compression fatigue of the rubber due to the weight of the wheel
combined with operation on sandy terrain or repeated sudden changes
in direction.
Abrasion of the carved profile. Rotation on concrete, gravel or hard surfaces.
Cracks on the outside surface of the
track.
Contact with gravel, sharp stones, metal, nails or glass.
Cracks on the inside surface of the
circumference and on the edge of the
rubber.
Contact between the track and the undercarriage structure or with
sharp concrete edges.
