Komatsu 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 electrically-controlled,
hydraulically-actuated and force-lubricated for optimum heat
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 rims are bolt-on for easy replacement.
Palm Command Control System (PCCS) lever controls for all
directional movements. Pushing the PCCS lever forward results in
forward machine travel, while pulling it rearward reverses the
machine. Simply tilt the PCCS lever to left to make a left turn.
Hydrostatic Steering System (HSS) is powered by steering planetary
units and an independent hydraulic pump and motor. Counterrotation
turns are also available.Wet, multiple-disc, pedal-controlled
service brakes are spring-actuated and hydraulically released. Gear
shift lock lever also applies parking brake.
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.
Plunger type hydraulic pump with capacity (discharge flow) of 210 ltr/min 55.5 U.S. gal/min at rated engine rpm.
