14.7 Tracks

14.7.1 Tightening

With use, tracks tend to loosen. When operating with loose
tracks, they tend to slip over the driving wheel causing it to
jump its housing or to work in precarious situation, thus
damaging wear to the housing.
To check track tightness, proceed as follows:
a. Set the machine on a flat surface with compact ground,
better on an asphalt or stone pavement.
b. Lift the machine and set it on blocks or supports rated for
the weight of the machine so that the tracks are
approximately 100mm off the ground.
c. Measure the track midline vs. the horizontal line. The
reading must not be more than 10 - 15mm.
If the distance is greater, proceed as follows:
a. Use the tipping handle to tip the dump box and set it on
blocks or supports rated for the weight of the box.
b. Loosen the locknut A. Tighten bolt B until the correct
tightness is restored.
c. Secure bolt B by tightening locknut A thoroughly.
d. Return the dump box to its original position

loss of braking action results.

e. Tilting bring back to the starting position.

14.7.2 Replacing tracks
