[2] POWER TRAIN FOR TRAVELING GEAR

The transmission consists of a series of gears and shafts as shown in previous page.
The traveling system consists of main gear shift section, shuttle shift section, range gear shift section and front
wheel drive section.

(1) Main Gear Shift Section

(2) Shuttle Shift Section

The main gear shift section is located in the clutch
housing, and it uses a synchromesh.
Power which is transmitted from the engine to the
gear shaft (1) via the clutch is changed in four ways by
operating the main shift lever to shift the shifters, and
transmits to the counter shaft (3).

The shuttle shift section is located in the mid case,
and it uses a double cone type synchromesh. It allows
the operator to change forward and reverse for each
speed from the first to eight with single shift lever.
The double cone type synchromesh is characterized
by its light operating force and durability because it
engages with the gear in reverse rotation when the
speed is changed from forward to reverse position or vice
versa.
Two synchronizing rings (7), (9) are installed on one
side, and the center ring (8) is provided between the
synchronizing rings.

improves the durability as compared with the ordinary
key type synchromesh.
