Undercarriages
The undercarriage assemblies typically operate in
harsh working conditions. They may work in mud,
gravel, debris and various other abrasive materials
during operation. ASV recommends a daily inspection
of the undercarriage assemblies and cleaning if neces-
sary.
Materials that are particularly sticky or abrasive like
clay, mud, or gravel should be cleaned from the under-
carriages more often to minimize component wear. A
pressure washer works well for cleaning materials from
the undercarriages. At times when a pressure washer
is not available, use a bar, shovel or similar device to
remove foreign materials.
When cleaning, pay particular attention to the drive
motors/sprockets and the front wheels where debris is
likely to accumulate. If traversing scrap or debris,
inspect more often and remove foreign objects that
may wrap around or lodge themselves between com-
ponents causing premature wear and damage.
Operating in loamy sand or on turf or other finished
surfaces may require less frequent cleaning, but daily
inspection is still advised.
Grease Fittings
The undercarriages are equipped with grease fittings
at the main torsion axle pivot points.
Lubricate fittings
daily or after every 10 hours of operation to ensure
proper operation and maximize component life.
Track Tension
Proper track tension must be maintained for optimal
performance and track/undercarriage life. Running a
track that is too loose may cause the track to misfeed,
possibly causing damage to the track and or undercar-
riage components. Running a track that is too tight
may cause track stretch, premature bearing failure, or
other preventable damage to the machine. Tracks
should only be tightened to the point where there is no
visible sag (when viewed from the side) between the
rear sprocket and the front idler wheels. Never tighten
the tracks beyond this point.
Adjustment
To tighten tracks:
1. Locate the input grease zerk (H) on the tensioner
unit (J) mounted within the frame rail. (fig. 4-26)
2. Connect a grease gun to the zerk and inject grease
into the tensioner until the track is properly ten
sioned.
The track tension adjustment procedure is now com-
plete.
If for some reason the tracks are too tight, loosen them
until tension is correct.
To loosen tracks:
1. Locate the grease bleeder bolt (I) adjacent to the
input zerk on the tensioner unit. (fig. 4-26)
2. Using a socket wrench and extension, loosen the
bleeder bolt slowly until grease begins to flow out
from around the bolt. Allow grease to bleed out
until track tension is correct.
Note: During the first 50 hours of operation the tracks
will "break-in" and will most likely require adjustment.
