2.4.2 FORWARD
Move the swash plate control lever to the left, the run-
ning swash plate will be angled as illustrated. As the
cylinder block is connected with the input shaft, it ro-
tates with the input shaft. When the cylinder block ro-
tates by passing the pump port A, oil comes in through
piston port and continues to rotate, the oil will be dis-
charged through pump port B.
When the oil is supplied to motor port B, oil pressur-
izes the piston by increasing the pressure. The piston
pushes against the fixed swash plate causing it to slide
down.
The piston tends to rotate the cylinder block because it
is attached on the cylinder block. The cylinder block
rotates output shaft.
If the cylinder block continues to rotate, the oil will be
discharged through motor port A with low pressure and
then return to pump port A.
