[3] OPERATION

Clutch "Engaged"
When the clutch pedal is not depressed, the clutch
release bearing (6) and the fingers of diaphragm spring
(3) are not connected to each other.
Accordingly, the pressure plate (2) is tightly pressed
against the flywheel (1) by the diaphragm spring (3).
As a result, rotation of the flywheel (1) is transmitted
to the transmission through the gear shaft (8) due to the
frictional force among the flywheel (1), clutch disc (10)
and pressure plate (2).

Clutch "Disengaged"
When the clutch pedal is depressed, the clutch rod is
pulled to move the clutch lever (11). Then, the release
fork (9) pushes the release hub (7) and release bearing
(6) toward the flywheel. Simultaneously, the release
bearing (6) pushes the diaphragm spring (3).
As the pressure plate (2) is pulled by the diaphragm
spring (3), the frictional force among the flywheel (1),
clutch disc (10) and pressure plate (2) disappears.
Therefore, rotation of the flywheel (1) is not
transmitted to the clutch disc (10), and then the rotation
of the gear shaft (8) stops.
