FATIGUE CRACKS AND ABRASION.
Cracks at the base of the carved profiles are caused by rubber fatigue due to bending.
Cracks and bends on the edge of the rubber are caused by manoeuvring the track on concrete edges
and curbs.
Cracks and abrasions in the rubber on the guide roller paths are caused by 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 may be caused, in particular, by rotation on concrete or gravel surfaces
or hard surfaces.
Cracks on the outside surface of the track are often due to contact with gravel, sharp stones and sharp
materials such as sheet metal, nails and glass.
Cracks on the inside surface of the circumference and on the edge of the rubber are caused by
contact between track and the undercarriage structure or with sharp concrete edges.
These methods of damage are progressive. The track can continue to be used until wear exposes the
metal cores. If this exposure extends for more than half of the circumference of the track then it is time
to replace the track, even though it can still be used.
SAFE MAINTENANCE
Solidly support the under carriage if it needs
to be lifted up for maintenance (see Chassis
Jacking Point section on page 20).
Hydraulic systems may get very hot after
working.
Keep all components in good condition as
they are exposed to high pressures.
Immediately repair damage and replace worn
or broken items.
Keep the tracks clean, removing excess oil,
grease and dirt.
Check for oil leaks and damaged hoses.
Only use recommended lubricants. Do not
mix different brands.
Keep track stretcher grease nipples clean.
TRACK BASE MAINTENANCE
Maintenance intervals are only guidelines. The amount
of times maintenance is conducted should be increased
beyond recommended guidelines if severe conditions
are encountered.
The structure of the rubber track is shown in this diagram. The
steel cables (1) and metal core (2) are embedded in the
rubber.
There are many ways in which rubber tracks may be
damaged. Some of these are terminal for the tracks, others
are only cosmetic.
BREAKAGES OF STEEL CABLES AND METAL CORES.
Excess track tension can cause steel cables to break. Excess tension may be caused by;
Stones or foreign matter accumulating between the track and the undercarriage frame.
The track slipping off its guide system.
Extreme friction such as rapid changes in direction.
Improper contact between track and sprocket.
Operation on sandy terrain.
