The structure of the rubber track is shown above. The steel cables and metal core are
embedded in the rubber. The carved profiles function gives stability on soft terrain. The wheel
guides, located on the inside of the track, preventing the track from sliding off the guide rollers.
BREAKAGE OF STEEL CABLES.
Excess track tension can cause steel cables to break in the following conditions:
When stones or foreign matter accumulate between the track and the undercarriage frame.
When the track slips off its guide system.
In case of great friction such as rapid changes in direction.
BREAKAGE OF METAL CORES.
Excess track tension can cause the metal cores to bend or break just like the steel cables as
stated above.
Other causes include:
Improper contact between track and sprocket.
Rotation of internal rollers.
Operation on sandy terrain.
MAINTENANCE OF DRIVE GEARED MOTORS.

and using the other to check the oil level.
REPLACEMENT OF OIL IN THE GEARBOX.
Replace the oil after the first 100 operating hours and then at subsequent 1000 hour I
ntervals. Proceed as follows to perform the replacement: - stop the reduction unit with the
plugs
(62 & 63) aligned vertically with (62) at the bottom - remove both plugs and drain out all the
