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.

2. SATIC (SELF ADJUSTING TECHNOLOGY WITH
INTEGRATED CASSETTE)
1) System Description
Function ▶
On the conventional clutch, the pedal force
tends to increase in proportion to the degree
of disc run-out. However, the SATIC clutch
has the adjusting function which activates the
cassette system inserted to the clutch cover
to maintain a constant pedal force and
clearance when the disc runs out. (Unlike SAT
type, SATIC type does not need SST for
clutch cover removal.)
Operation ▶
Diaphragm spring rotates the adjusting
equipment as clutch disc is wearing and so,
pressure plate is pushed to clutch disc side at
the amount of wear.
Disc wear (Free
play) → Diaphragm spring (1)
→ Adjusting equipment (2, 3) → Pressure
plate (4)

2) Overview
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.
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.

3. DUAL MASS FLYWHEEL (DMF)
The dual mass flywheel (DMF) is of having a mass divided into two halves.
While one mass is connected to the engine crankshaft, which is affected by the mass moment of
inertia of the engine, the other mass is affected by one of the transmission.
The divided dual masses are connected to the coil spring and damping system internally.
The DMF has the following benefits: ▶
Reducing fuel consumption by lowering engine speed
Reducing rattling noise and vehicle vibration in all driving ranges
Reducing synchronization wear
Facilitating gear change
Protecting power train parts by preventing excessive load from being delivered -
