High Performance Komatsu SDA12V160 Engine
The Komatsu SDA12V160 engine provides the highest
horsepower in it’s class. With 1487 gross horsepower, this
engine delivers faster acceleration and higher travel speeds
with a high horsepower-to-ton ratio. High torque at low
speed, impressive acceleration, and low fuel consumption
ensure maximum productivity. Standard features of this
engine include the Quantum electronic control system,
Cummins Cense monitoring and pre-lubrication.

Seven-Speed Electronically Controlled, Automatic
Powershift Transmission
Komatsu’s seven-speed, electronically controlled, automatic
powershift transmission uses a rubber damper to
comfortably reduce harmful engine shock and vibration to
the transmission. A lock-up system, consisting of a wet
multiple-disc clutch, is actuated in F1-F7 gears for higher
fuel savings. Electronic shift control with automatic clutch
modulation in all gears and full diagnostics with memory.
The transmission circuit uses a separate hydraulic circuit
and cooler.
Komatsu torque converter is transmission-mounted and
lock-up clutch is electronically controlled.
Maximum travel speed (empty, 2% rolling resistance)

Four-Wheel, Oil Cooled, Multiple Disc Brakes
The HD1500-7 is equipped with four wheel, oil cooled,
multiple disc brakes which provide the greatest retarding
capabilities in its class. Effective and smooth braking
characteristics are controlled through the retarding lever by
a system of pressure proportioning valves (PPC), which
precisely meter the appropriate amount of hydraulic
pressure to each brake assembly. The elimination of an air
system, common with dry disc brakes, improves reliability
and reduces maintenance costs.
