The engine power is transmitted smoothly to the final drives, via a high-efficiency torque converter. And this engine also meets emission standards without sacrificing power or machine productivity. VPA SINISSshoin imple and easy to select speeds and change direction. Both can be The Komatsu Toratow system makes done by shifting a single joystick. Komatsu Toraflow Power Train The Komatsu Toraflow power train consists of torque converter and planetary power shift transmission. The torque converter is placed between the engine and transmission. Torque Converter The torque converter automatically varies the power required at the tracks to meet the changing load requirements of the machine. Engine power is transferred by the converter with little change in torque when the load is light. Torg-flow Engine power is transmitted to the transmission through the torque converter (hydraulic coupling) ol. When a heavy load is encountered, the torque multiplication becomes greater, resulting in reduction of tractor speed Torque Transmission At this moment, the torque converter increases the Converter amount of torque available for the tracks without increasing engine horsepower Advantages @ Easy gear shifting @ Engine does not stall even a heavy load suddenly| comes (TC relieves load) Small power gap at speed shift Good power persistence in heavy job OPS WAT COMWMRORY All steering, direction and speed changes are made by a left-hand single joystick control. If the operator wants to move the machine forward and to the left, he simply moves the joystick control forward and to the left. If he desires a gear changes, he merely twists his wrist. The machine responds the movement to the lever providing the operator with the feeling of natural control with Komatsu’s joystick, ‘Steering Function Blade Function Winch Functions. ronan and = exe on an O ee lowerg @ ex aie O iat First, to second, Sow Fay Free drum and engaged Easy to operate Work Equipment Control Advantages of CLSS Lever More precise and responsive operation With the Closed center Load Sensing System due to the pressure compensation (CLSS), blade lever stroke is directly proportional valve, with blade speed, regardless of the load and travel speed.

Large-diameter bushings, increased track link heights, and improved oil-seals ensure maximum reliability and durability. Transmission Steering Case Assembly a Engine ~ Final Dive Assomoy \ §eRee, scopy Phvot Shaft Hull Frame Dt tinied Durability Fewer components means greater reliability. We've designed a simple hull frame made of a thick, single plate. Track frames have a large- section structure for maximum rigidity. Even the box-section construction of the blade back beam is reinforced, all with durability in mind. 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. Modular Designed Power Train Units The modular design allows easy removal and installation of any individual unit for shorter downtime. LAS WWAULSTU LSA OLS Gull-Wing Engine Side Covers With a gas-spring cylinder that opens widely, the engine and the auxiliary components can be checked easily Remote Greasing Serviceability has also been improved with the addition of remote greasing of equalizer bar center pin. Wet, Multiple-Disc Brakes The wet type multiple-disc brakes eliminate brake-band adjustments for mainte- nance-free operation. Reservoir Check Ports Oil pressure test ports for the power train are centralized on the right hand side of the operator platform for easy access.

Pushing the joystick forward results in forward machine travel, while pulling it backward reverses the machine. Simply tlt the joystick to the left to make a left turn. Tilt it to the right to make a right turn, ‘Speed range can be selected by twisting the joystiok. Wet, multiple-disc, pedal-controlled service brakes are spring actuated and hydraulically-released. ‘The directional and gear control joystick lock lever also applies the brakes.
