[2] CLUTCH OPERATION
(1) Clutch "Engaged"
(2) Clutch "Disengaged"
When the clutch pedal is not depressed, the clutch
release bearing (8) and the fingers of the diaphragm
spring (5) are not connected to each other.
Accordingly, the pressure plate (4) is tightly passed
against the flywheel (1) by the diaphragm spring (5).
As a result, rotation of the flywheel (1) is transmitted
to the transmission through the clutch shaft (10) due to
the frictional force among the flywheel (1), the clutch disc
(2) and the pressure plate (4).

(4) Pressure Plate
(5) Diaphragm Spring
When the clutch pedal is depressed, the clutch pedal
rod is pulled to move the clutch rod (7). Then, the release
fork (6) pushes the release hub (9) and release bearing
(8) toward the flywheel. Simultaneously, the release
bearing (8) pushes the diaphragm spring (5).
As the pressure plate (4) is pulled by the diaphragm
spring (5), the frictional force among the flywheel (1), the
clutch disc (2) and the pressure plate (4) disappears.
Therefore, rotation of the flywheel (1) is not
transmitted to the clutch disc (2), and then the rotation of
the clutch shaft (10) stops.
