[6] SHIFT LINKAGE MECHANISM

For shift linkage mechanism of "Shuttle Lever" and "Front Wheel Drive Lever", refer to page 3-M6.
The GST clutch is hydraulic multiple plate type and is
provided between the counter shaft (3) and the shuttle
shaft (8), and it "engages" and "disengages" the
power from the engine.
operation of clutch valve (2).
Engaging (When the shift gear is at desired
position while engine is running)
The oil from clutch valve (2) flows in to push the return
spring (9) and the piston (6). The piston is pushed to the
left by the oil, thereby pushing the clutch discs (4) and the
plates (5) to transmit the power.
Disengaging (When the engine stop, the shift
levers are neutral position, between from start to
end of the gear shifting)
The oil of the GST clutch (1) is pushed out with return
spring (9) and piston (6), and flowed to the tank.
