3.3 OPERATION

CLUTCH “ENGAGED”

When the clutch pedal is not depressed, the clutch re-
lease bearing (3) and the fingers of diaphragm spring
(4) are not connected to each other.

Accordingly, the pressure plate (6) is tightly pressed
against the flywheel (8) by the diaphragm spring (4).

As a result, rotation of the flywheel (8) is transmitted to
the transmission through the shuttle shaft (9) due to
the frictional force among the flywheel (8), clutch disc
(7) and pressure plate (6).

(1) Clutch Release Fork

(2) Release Hub

(3) Release Bearing

(4) Diaphragm Spring

(5) Clutch Cover

(6) Clutch Pressure Plate

(7) Clutch Disc

(8) Flywheel

(9) Shuttle Shaft

(10) Clutch Lever Shaft

CLUTCH “DISENGAGED”

When the clutch pedal is depressed, the clutch rod is
pulled to rotate the clutch lever shaft (10). Then, the
release fork (1) pushes the release hub (2) and re-
lease bearing (3) toward the flywheel. Simultaneously
the release bearing pushes the diaphragm spring (4),
the frictional force among the flywheel (8), clutch disc
(7) and pressure plate (6) disappears.

Therefore, rotation of the flywheel (8) is not transmitted
to the clutch disc (7) stopping the rotation of the shuttle
shaft (9).
