TORQFLOW TRANSMISSION
Komatsu TORQFLOW transmission consists of a water-cooled,
3-element, 1-stage, 2-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
machine from accidental starts.
STEERING 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. Tilt it to the right for a right turn.
Hydrostatic Steering System (HSS) is powered by steering planetary
units and a hydraulic pump and motor. Counter-rotation 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.

Track shoes
Lubricated tracks. Unique seals prevent entry of foreign
abrasive material into pin to bushing clearances to provide
extended service life. Track tension is easily adjusted with grease
gun.
FINAL DRIVES
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.
