1. OVERVIEW
The hydraulic clutch transmits the force required to operate the clutch pedal to the concentric slave
cylinder fitted to the clutch housing as a hydraulic pressure.
(The hydraulic pressure is transmitted in the following order: Clutch pedal - Clutch master cylinder -
Clutch pipe - Clutch damper - Clutch pipe and hose - Concentric slave cylinder - Pressure plate -
Flywheel.)
If a driver depress the clutch pedal, the hydraulic pressure is generated in the master cylinder. It is
transmitted to the concentric slave cylinder through the pipe, resulting in the cylinder being forced out. At
this time, the clutch disc is forced against the cylinder by pushing the cover. This, in turn, remove the
flywheel from the pressure plate. As a consequence, the power from the engine will be cut off and the
gear change can be carried out.

Operating Elements
The clutch "release" system consists of the clutch pedal and clutch release cylinder.
This system directly releases the clutch by using hydraulic pressure while the conventional clutch system
releases the clutch by using release lever and release fork. This system provides higher efficiency than
conventional clutch system, and its durability is superior.

-Driving elements
The driving elements consist of two flat surfaces machined to a smooth finish.
One of these is the rear face of the engine flywheel and the other is the clutch pressure plate. The clutch
pressure plate is fitted into a clutch steel cover, which is bolted to the flywheel.
Driven elements
The driven element is the clutch disc with a splined hub which is free to slide lengthwise along the splines
of the input shaft.
The driving and driven elements are held in contact by spring pressure. This pressure is exerted by a
diaphragm spring in the clutch cover pressure plate assembly.
