Idlers and rollers
Check the general condition of vulcanized midroller and idler wheels.
x
Review the inner side of the wheels where they contact the drive lugs. Excessive wear in
these areas can be caused by continuous hillside work: see the “Proper use,
precautions, not authorized use” section.
x
Look for material imbedded into the surface of the idlers and midrollers. Remove
imbedded objects to prevent damage to the inside surface of the track.
x
Inspect for material build up on the rubber surface. If material build up is related to the
rubber coating worn too thin, replace midroller or idler.
x
Inspect for missing or damaged rubber surface. Replace midrollers or idlers if any of the
following conditions exists:
o
More than 1/3 of the rubber is missing all the way around the wheel
o
Anytime the rubber is missing all the way across the width of the wheel
o
The wheel has a flat spot or does not turn smoothly.
o
The steel core is bent, cracked or damaged
Rubber track drive lugs
Sharp cuts could be visible at the base of track drive lugs, even after a
short work period. This is related to the track bending and the forces
applied to the drive lugs during use on the undercarriage. The cuts are
typically spread randomly and stop growing once they are some
millimeters in depth. These cuts are typical and do not compromise the
performance or life of the track.
Track carcass
Inspect track surface to remove imbedded stones or debris. This contamination can work its way
into the track and damage the steel cable.
Steel wire may come out from the track carcass without affecting the performance of the track.
Remove loose wires by cutting them at the rubber surface.
Track tread
Muddy soils usually cause limited
wear, while roading long distances
can bring about accelerated tread
wear. Due to the crown of the road,
and deflection in the system, the
tread closest to the tractor will tend to
wear faster than the tread on the
outer portion of the track.
Should the height difference between
the tread measured on ¼ and on ¾
of the track width differ averagely of
more than 5 mm (see the picture),
swap tracks side to side on the
machine following the instructions of
“Track exchange side to side”
paragraph in “Scheduled maintenance”
section.
