7.12 General Undercarriage Information
The undercarriage assemblies typically operate in harsh working
conditions. They work in mud, gravel, debris and various other abra-
sive materials during operation. Terex recommends a daily inspec-
tion of the undercarriage assemblies and cleaning if necessary.
Materials that are particularly sticky or abrasive like clay, mud, or
gravel should be cleaned from the undercarriages often to minimize
component wear. A pressure washer works well for cleaning materi-
als from the undercarriages. At times when a pressure washer is not
available, use a bar, shovel or similar device to carefully remove for-
eign materials.
When cleaning, pay particular attention to the drive motors/sprockets
and the front and rear wheels where debris is likely to accumulate. If
working in scrap or debris, inspect the undercarriages more often
and remove foreign objects that may wrap around or lodge them-
selves between components causing premature wear and damage.
Operation on sand, turf, or other finished surfaces may require less
frequent cleaning, but daily inspection is still advised.
7.13 Track Tension Check
Proper track tension is important for optimum performance and max-
imum track life. Operating with tracks that are too loose can cause
them to misfeed, possibly causing damage. During the first 50 hours
of operation, the tracks will "break-in", and may require adjustment.
To check for proper track adjustment:
1. Drive the machine forward 1.5 meters to remove slack from the
lower and rear portions of the track. Stop the engine and
remove the key from the ignition.
2. Lay a straight edge along the top of the track, across the
sprocket and the front idler wheel (fig. 7.13-1).
3. Using a rope or wire, put 23 kg of down force on the track at
the mid point between the sprocket and idler.
4. Using a ruler or tape, measure the distance between the
straight edge and track (fig. 7.13-2). The track should not
deflect more than 1.9 cm between the top of the track and the
straight edge.
5. If the track does deflect more than 1.9 cm, tighten the track
until within specification.
