CLUTCH
1. DRY TYPE, SINGLE PLATE CLUTCH
■ Clutch “Engaged”
When the clutch pedal is not depressed, the clutch
release bearing (9) and the fingers of diaphragm spring
(5) are not connected to each other.
Accordingly, the pressure plate (4) is tightly pressed
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), clutch disc (2) and
pressure plate (4).
W10126980
■ Clutch “Disengaged”
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 (8) and release
bearing (9) toward the flywheel. Simultaneously, the
release bearing (9) pushes the diaphragm spring (5).
As the pressure plate (4) is pulled by the diaphragm
spring (5), the frictional force among the flywheel (1),
clutch disc (2) and 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.

CLUTCH
2. DRY TYPE, DUAL STAGE CLUTCH
A dual stage clutch is a combination of two single
plate clutches. One clutch controls power transmitted to
travelling, and the other to the PTO.
■ Travelling Clutch “Engaged”
■ PTO Clutch “Engaged”
When the clutch pedal is not depressed, there is a
certain amount of clearance between the release bearing
(17) and the adjusting screw (16) mounted on the release
lever (15). Under the conditions above;
• The travelling clutch disc (10) is pressed between the
flywheel (1) and the pressure plate 1 (2) by the force
of the belleville spring (11).
• The PTO clutch disc (12) is pressed between the
clutch cover 1 (4) and the pressure plate 2 (5) by the
force of the belleville spring (14).
Thus, the rotation of flywheel is transmitted to both
the travelling and PTO systems.

■ Travelling Clutch “Disengaged”
■ PTO Clutch “Engaged”
When the clutch pedal is depressed to the middle of
the stroke, the clutch rod (9) is pushed to move the clutch
lever (8). Then, the release fork (7) pushes the release
hub (19) and release bearing (18) toward the flywheel.
Simultaneously, the release bearing (18) pushes the
adjusting screw (17) attached to the release lever (16).
The release lever pulls the pressure plate 1 (2) by
means of the release rod (13) as the lever turns at the
clevis pin (15) as a fulcrum.
When the pressure plate 1 is pulled, friction force
among the clutch cover 1 (4), clutch disc (10) and the
pressure plate 1 (2) is lost. The rotation of flywheel is not
transmitted to travelling system.
At this time, the pressure plate 2 (5) is in contact with
the head of the adjusting screw (3) which serves as a
stopper.

CLUTCH
■ Travelling Clutch “Disengaged”
■ PTO Clutch “Disengaged”
When the clutch pedal is depressed to the full stroke,
the pressure plate 2 (5) is pushed to the right by the
adjusting screw (3).
This results in no friction among the flywheel (1),
clutch disc (12) and pressure plate 2 (5).
The rotation of flywheel is not transmitted to PTO
system and travelling system.
