Komatsu components
Komatsu manufactures the engine, torque converter,
transmission, hydraulic units, and electrical parts on this
dump truck. Komatsu dump trucks are manufactured with an
integrated production system under a strict quality control
system.
High-rigidity frame
Cast-steel components are used in the
main frame for highstress areas where
loads and shocks are
most concentrated.
Rigorous dump body design
The standard dump body is made of 160 kg/mm2227,520 PSI
high-tensile-strength steel for excellent rigidity and reduced
maintenance cost. The Vshape design also
increases structural strength.
The side and bottom plates of
the dump section are reinforced with ribs for added
strength.
Reliable hydraulic system
The oil cooler is installed in the radiator lower tank, improving the reliability of the hydraulic system during sudden temperature rises. Further, in addition to the main filter, a 25micron line filter is at the entrance to the transmission control valve. This system helps to prevent secondary faults.
Flat face-to-face O-ring seals
Flat face-to-face O-ring
seals are used to securely
seal all hydraulic hose
connections and to prevent
oil leakage.

EATURES
F
O-ring
Sealed DT connectors
Main harnesses and
controller connectors are
equipped with sealed DT
connectors providing high
reliability, water resistance
and dust resistance.
ABS (Antilock braking system) (Option)
Using its outstanding electronics technology, Komatsu is
the first in the industry to introduce ABS on construction
machinery. This system prevents the tires from locking,
thus minimizes skidding under slippery conditions while
applying the service brake.
ASR (Automatic spin regulator) (Option)
ASR automatically prevents the rear tires on either side
from slipping on soft ground for optimal traction.
Pedal-operated secondary brake
If there should be a failure in the foot brake, the parking
brake and front disc brakes
are activated as pedal operated secondary brake. In addition, when hydraulic pressure
drops below the rated level,
the parking brake is automatically actuated.
Lead-free radiator
In addition to compliance with emission regulations, a leadfree aluminum core is adopted for the radiator to comply
with global environmental requirements.
Brake cooling oil recovery tank
To protect environment, a tank is installed to recover brake
cooling oil in the event of brake floating seal leakage.

E
Advanced monitoring system
The Komatsu advanced monitoring system identifies maintenance items, reduces diagnostic times, indicates oil and
filter replacement hours and displays abnormality codes.
This monitor system helps to maximize machine production
time.
Wet multi-disc brakes and fully hydraulic braking
systems mean lower maintenance costs and higher relia-
bility. Wet disc brakes are fully sealed to keep contaminants
out, reducing wear and maintenance. Brakes require no
adjustments for wear, meaning even lower maintenance.
Added reliability is designed into the braking system by the
use of three independent hydraulic circuits providing
hydraulic backup should one of the circuits fail. Fully
hydraulic braking systems eliminate the air system so air
bleeding is not required, and water condensation that can
lead to contamination, corrosion and freezing is eliminated.
Extended oil change intervals
In order to minimize operating costs, oil change intervals
have been extended:
● Engine oil 500 hours
● Hydraulic oil 4000 hours
Centralized arrangement of filters
The filters are centralized so that they can be
serviced easily.

Even if the driver downshifts accidentally,a speed appropriate to the current gear is automatically set,preventing over-runs.
When descending grades, if the vehicle's speed surpasses the maximum for the current gear,
the rear brakes automatically operate, preventing over-runs.
The vehicle is prevented from moving backward when operating the body.
This device makes it impossible to shift from forward to reverse when the vehicle's speed surpasses 4 km/hour.
When running near a shift point, smooth automatic shifting takes place.
The engine is prevented from starting when the shift lever is not in neutral.
To determine travel performance: Read from
gross weight down to the percent of total
resistance. From this weight-resistance point,
read horizontally to the curve with the highest obtainable speed range, then down to
maximum speed. Usable rimpull depends
upon traction available and weight on drive
wheels.
