Field-Proven Engine
Powerful S6D125E-2 (D65P) and 6D125E-2 (D65E) diesel
engines provide a massive output of 142 kW 190 HP (D65P)
and 135 kW 180HP (D65E). The engine power is
transmitted smoothly to the final drives via a high-efficiency
torque converter.
Modular Designed Power Train Units
The modular design allows easy removal and installation of
any individual unit for shorter downtime.
Flat Bottom Frame
A
flat bottom frame,
the monocoque track frames and
forward-mounted pivot shafts provide good maneuverability
in muddy terrain by preventing mud from building up under
the frame.
Sturdy Design
Because fewer components mean greater reliability, we’ve
designed a simple hull frame made of a thick, single plate.
Track frames have a large-section construction for maximum
rigidity. Even the box-section construction of the blade back
beam is reinforced, all with durability in mind.

Tough Undercarriage
Large-diameter bushings, increased track link heights, and
improved oil-seals help to increase undercarriage durability.
Serviceability has also been improved with the addition of
remote greasing of the equalizer bar center pin.
Low Drive and Long Track Undercarriage
Komatsu’s design is extraordinarily tough and offers
excellent grading ability and stability.
Wet, Multiple-Disc Brakes
Eliminate brake-band adjustments for
maintenance-free operation.
Coolant Reservoir
A radiator coolant reservoir
makes it easier to check the
coolant level and eliminates
frequent refilling.
Oil Pressure Check Ports (optional)
Oil pressure check ports for the power train
are centralized on the right hand side of the
operator platform for easy access.
Gull-Wing Engine Side Covers
(optional)
A gas-spring cylinder opens the gull-wing
engine side covers widely, allowing the engine
and auxiliary components to be easily
checked.
