16.9 Tracks

16.9.1 Tighten

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
Tigthen 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
WARNING
The adjustment of the chains affect the brakes. Please with great caution proceed as a chain
spanned loss of braking action results.
If the adjustment does not allow further adjustment more, the chain should be replaced.
e. Tilting bring back to the starting position.

16.9.2 Replacing

Check the condition of the tracks periodically. If any
track is cracked or frayed, it should be replaced as
soon as convenient.
