SystemOne™ Undercarriage.
Exclusively for Caterpillar machines the
design extends system life and reduces
operating costs.
• Long-life Sprocket. Extended life
sprockets will outlast two or more
tracks. The rotating bushing
technology extends life.
• Guiding System. The guiding
system contacts link rails instead
of pin ends and helps keep the track
within the roller system. The result
is improved track guiding.
• Rollers. The increased flange
diameter on the rollers provide
optimum guiding and longer life.
• Carrier Rollers. Redesigned carrier
rollers are factory sealed and serviced
as a unit. The larger diameter provides
extended wear to better match
undercarriage system life.
• Idlers. The center tread idlers
contact only the bushing – not the
links – eliminating scalloping and
providing more guiding to the link
assembly. The idlers last longer
because they contact a rotating
bushing instead of a link rail.
• Cartridge Joints. Factory-sealed
cartridge joints are laser welded to
control end play. They offer improved
seal integrity through an innovative
new sealing system and do not
depend on the link interface to
remain sealed. As with all Cat
undercarriage products, they are
filled with special oils.
• May be used in any application.
• The track roller frames are welded
and have a box section design,
which provides strength and
resistance to bending without
adding extra weight.
• The track adjuster and mechanical
recoil spring and grease filled
adjustment cylinder which allows
the idler to move forward and back
to maintain proper track tension as
it absorbs undercarriage shock.
Undercarriage Arrangements.
XL (Extra Long) arrangement
• Forward idler position provides
more track on the ground and to
the front of the tractor. It provides
optimal balance, superior traction
and blade control for finish grading.
• Long roller frame provides good
flotation in soft underfoot conditions.
LGP (Low Ground Pressure)
arrangement
• Specially designed to work in soft
underfoot conditions.
• Wide track shoes, a longer track
frame and a wider gauge increase
track contact area and reduce ground
pressure for excellent flotation.
Complete Guarding. Caterpillar
undercarriages are designed with full
length guarding on top of the track
roller frame. This prevents abrasive
materials from being recirculated in
the track.
Roller Frames. Roller frames attach to
the tractor by a pivot shaft and pinned
equalizer bar.
Oscillating Undercarriage. The pinned
equalizer bar is saddle-mounted
beneath the mainframe, allowing the
roller frames and track to oscillate.
The oscillation provides a steady
working platform and smooth ride
for the operator.
