TRANSMISSION
â– Forward
When the speed control pedal is stepped on and in forward, the swashplate (14) is tilted as shown in the figure
above.
As the pump cylinder block (15) rotates with the pump shaft (13), oil is forced out of pump port B at high pressure.
As the pressure oil enters motor port D, the pistons, which align with port D, are pushed against the inclined thrust
plate slide down the inclined surface.
Then the motor shaft (8) rotates with the motor cylinder block (7). This drives the machine forward and the angle
of swashplate (14) determines the motor shaft speed.
