Komatsu TORQFLOW transmission consists of a water-cooled,
3-element, 1-stage, 1-phase torque converter with lockup clutch
and a planetary gear, multiple-disc clutch transmission which is
hydraulically-actuated and force-lubricated for optimum heat
dissipation. Gearshift lock lever and neutral safety switch
prevent accidental starts.
Double-reduction final drive of spur and planetary gear sets to
increase tractive effort and reduce gear tooth stresses for long final
drive life. Segmented sprocket teeth are bolt-on for easy replacement.
PCCS lever, joystick-controlled, wet multiple-disc steering clutches
are spring-loaded and hydraulically released.Wet multiple-disc
steering brakes are spring-actuated, hydraulically released, and
require no adjustment. Steering clutches and brakes are interconnected
for easy, responsive steering.
Closed-center load sensing system (CLSS) designed for precise and
responsive control, and for efficient simultaneous operation.
Hydraulic control units:
All spool valves externally mounted beside the hydraulic tank.
Piston type hydraulic pump with capacity (discharge flow) of
542 ltr/min 143 U.S. gal/min at rated engine rpm.
