2 Large defor-mation of the rubber pads contributes to greater suspension as a conventional rigid frameOn uneven groundSeesaw movement isperformed corresponding to ground ride even on uneven groundMinimum shock in riding over obstaclesOn uneven ground, the rubberpad provides four times thesuspension riding over obstacles, the height of the machine fall is ground travelSuspension effectRough terrain travel14 Obstacle height BFall height AConventionalrigid typeREUABI nnerbogieRubberpadOuterbogieTrackrollerS haft:Fixed to trackframeCenterUNDERCARRIAGEUNDERCARRIA GEA dvanced ResilientEqualized Undercarriage(REU)The Komatsu X-type bogie Resilient EqualizedUndercarriage (REU) performs independentseesaw movements. Tremendous traction can be achieved even on uneven ground,because the shoe always follows the contourof the ground.

3 To decrease vibration andshock, a rubber shock absorber is mountedon the X-type bogie. The X-type bogie andrubber cushion provide different absorptioncharacteristics, depending on the groundsurface. When the machine travels on flatground, the REU functions as a conventionalrigid undercarriage. When the machine travelson uneven ground, the REU maximizes thesuspension effect. The Komatsu REU systemimproves traction, component durability, andoperator Lever SteeringAll steering and directional changes can be made with a wrist control, singlelever at the operator s left hand. The machine responds to the movement ofthe control lever providing the operator with the feeling of natural control; if the operator wants to move the machine forward and to the left, he simplymoves the joystick forward and to the DOZERK omatsu SA6D140E-1 Turbocharged Diesel EngineENGINE ANDTORQUECONVERTERENGINE ANDTORQUECONVERTERP owerful EngineA powerful SA6D140E-1 turbocharged diesel engine provides a massive output of 231 kW 310 HP.

4 The engine power is transmitted smoothly to the final drives via a high-efficiency torque converter. And this engine also meets current emissions standards, without sacrificing power or machine engine Side CoversThe gull-wing engine side covers open widely, using a gas spring cylinder so the engine and the auxiliary components can be checked speedForwardReverse1st0 km/h 0 mph0 km/h 0 mph2nd0 km/h 0 mph0 km/h 0 mph3rd0 km/h 0 mph0 km/h 0 mphSPECIFICATIONSSPECIFICATIONSENGINEK omatsu SA6D140E-1, water-cooled, 4-cycle, turbocharged andaftercooled, diesel engine , 6 cylinders with 140 mm " bore x 165 mm " stroke and ltr 930 in3piston horsepower* .. 251 kW 337 HP@ 1900 rpmFlywheel horsepower** .. 231 kW 310 HP@ 1900 rpmMaximum torque .. 164 kg/m 1,186 lb/ft @ 1250 rpm* Gross horsepower output for complete engine operating under J1995 conditions.

All-speed mechanical governor. Forced lubrication driven by gear pump. Full-flow filter for lube oil purification. Dual element, dry-type air filters with automatic dust ejector and dust indicator. 11 kW/24 Velectrical starting motor. 35 A/24 Valternator. 170 Ah/2 x 12 V TRANSMISSIONK omatsu s TORQFLOW transmission consists of a water-cooled, 3-element, 1-stage, 1-phase torque converter and a planetary gear,multiple-disc clutch transmission which is hydraulically actuated andforce-lubricated for optimum heat dissipation. Joystick control of gears(3 forward and 3 reverse) and directional and steering lock lever and neutral safety switch prevent machine from accidental DRIVED ouble-reduction, spur and planetary final drives increase tractive effort.

6 Segmented sprockets are bolt-on for easy in-the-field controls for all directional movements. Pushing the joystickforward results in forward machine travel, while pulling it rearwardreverses the machine. Simply tilt the joystick to the left to make a left turn. Tilt it to the right for a right Steering System (HSS) is powered by steering planetaryunits and an independent hydraulic pump and motor. Counterrotationturns are also available.
