Main frame High-rigidity simple main frame structure combined with thick plates and steel castings provide increased reliability and durability. extend undercarriage life. Protected travel motors and final drives HST with electronic control The D39 is equipped with Komatsu-designed Hydrostatic Transmission (HST) that allows for Quick-Shift or variable speed selection. The HST consists of dual-path closedcircuits with two variable displacement piston pumps and two variable displacement travel motors. Hydrostatic steering eliminates steering clutches and brakes, providing smooth powerful turns. [. . . ] Service reminders for fluids and filters are also indicated. Fuel efficient electronic controlled engine The Komatsu SAA4D107E-1 engine delivers a net output of 79 kW 105 HP at 2200 rpm. The powerful Komatsu engine incorporated into the D39-22 makes this dozer fuel efficient and the logical choice in both grading and dozing operations. The engine is turbocharged and features direct fuel injection and air-to-air aftercooling to maximize power, fuel efficiency, and emission compliance. To minimize noise and vibration, the engine is iso-mounted to the main frame. Hydraulically-driven cooling fan The engine cooling fan rotation speed and direction is electronically controlled. The fan rotation speed depends on engine coolant and hydraulic oil temperatures; the higher the temperature, the higher the fan speed. This system increases fuel efficiency, reduces operating noise levels, and requires less horsepower than a belt-driven fan. Hydrostatic Transmission (HST) control system The HST controller monitors engine output and work equipment/travel load. It controls HST pump and motor displacement to provide the optimum speed and drawbar pull. Power to both tracks during turns and counter-rotation makes the D39 extremely maneuverable. Photo may include optional equipment. Daily checks All daily checks can be performed efficiently at ground level. Remote grease points Remote grease points facilitate lubrication of the C-frame pivots and angle cylinder bearing. Long track-on-ground Long track-on-ground improves machine stability and grading/dozing performance. Adjustment-free parking disc brake An adjustment-free spring-applied hydraulic release wet parking brake is located in each final drive. Photo may include optional equipment.
