TORQFLOW TRANSMISSION
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.
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.
STEERING SYSTEM
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 inter-
connected for easy, responsive steering.

K-Bogie Undercarriage
Lubricated track rollers are resiliently mounted to the track
frame with a bogie suspension system whose oscillating motion
is cushioned by rubber pads.
Extreme Service Track Shoes
Lubricated tracks. Unique seals prevent entry of foreign
abrasives into pin to bushing clearances to provide extended
service life. Track tension is easily adjusted with grease gun.
