Master Cylinder

A07RW071

The master cylinder converts mechanical energy into
hydraulic energy.
Depressing the clutch pedal causes the push rod to move
against the piston to close the return port.

Clutch fluid is forced out of the master cylinder.
Releasing the clutch pedal causes the return spring to
force the piston back to its original position.

In order to reduce the occurrence of noises at the clutch
hydraulic system, the damper cylinder is used in the

clutch hydraulic line between the master cylinder and
slave cylinder.

A07RW037

The slave cylinder converts hydraulic energy into
mechanical energy.  Hydraulic fluid supplied by the
master cylinder moves the slave cylinder piston to

actuate the shift fork.  The mechanical energy produced
by the slave cylinder is directly proportional to the
diameters of the master cylinder and the slave cylinder.
