Engine   
Model    Komatsu SA12V170E 
Type    4-stroke, water-cooled, direct injection 
Aspiration    Turbocharged, aftercooled 
Number of cylinders    12 
Bore  6.69''  170 mm 
Stroke  6.69''  170 mm 
Piston displacement  2,825 in³  46.3 ltr 
Horsepower rating @ 1800 rpm:     
Net power SAE J1349  1,150 HP  858 kW 
Governor    All-speed, electrical 
Lubrication system:     
Method    Gear pump, force lubrication 
Filter    Full-flow and bypass combined 
 
TORQFLOW Transmission   
Komatsu TORQFLOW transmission consists of an air-cooled, 3-element, 1-stage, 1-phase torque converter with lock-up clutch and a planetary gear, multiple-disc clutch transmission which is actuated by ECMV (Electronic Control Modulation Valve) and force-lubricated for optimum heat dissipation. 
Travel Speed     
1st Forward   2.3 mph  3.7 km/h 
1st Reverse   2.7 mph  4.3 km/h 
2nd Forward   4.1 mph  6.6 km/h 
2nd Reverse   4.8 mph  7.7 km/h 
3rd Forward   7.5 mph  11.6 km/h 
3rd Reverse   8.3 mph  13.3 km/h 
 
Final Drive   
Triple-reduction final drive uses two-stage spur and single-stage planetary gears (five) to minimize transmission of shock to power train components. Segmented sprocket rims are bolt-on type for easy in-the-field replacement. 
 
Steering System   
PCCS lever, joystick-controlled, wet multiple-disc steering clutches are spring-loaded and hydraulically released. Wet, multiple-disc, pedal/lever-controlled steering brakes are spring-actuated, and hydraulically released, and require no adjustment. Steering clutches and brakes are interconnected for easy, responsive steering. 
 
Undercarriage   
Suspension    Oscillating equalizer bar and pivot shaft 
Track roller frame    Box-section, high-tensile-strength steel construction 
Rollers and idlers    Lubricated track rollers 
Resilient equalized undercarriage    Lubricated track rollers are resiliently mounted to the roller frame with a series of X-type bogies whose oscillating motion is cushioned by rubber pads. 
Extreme service track shoes    Lubricated tracks. Unique seals prevent entry of foreign abrasives into pin to bushing clearances to provide extended service life. Track tension is easily adjusted with grease gun.
