Komatsu's automatic TORQFLOW transmission consists of water-cooled, 3-element, 1-stage, 1-phase torque converter and a planetary gear, multiple-disc clutch transmission which is hydraulically actuated and force-lubricated for optimum heat dissipation. Joystick control of gears (3 forward and 3 reverse) and directional steering changes.
Gearshift lock lever and neutral safety switch prevent accidental starts.
Double-reduction final drives of spur-gear and planetary gears to minimize transmission of shocks to power train components. Segmented sprocket are bolt-on for easy in-the-field replacement.
Joystick controls for all directional movements. Pushing the joystick forward results in forward machine travel, while pulling it rearward reverses the machine. Simply tilt the joystick to the left to make a left turn. Tilt it to the right for a right turn. Wet, multiple-disc steering clutches are hydraulically loaded and hydraulically released.Wet, multiple-disc brakes are spring-actuated and hydraulically released. Steering brakes also function as service and parking brakes.
