2. SATIC (SELF ADJUSTING TECHNOLOGY WITH 
    INTEGRATED CASSETTE)

Function

▶

Operation

▶

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.)

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)

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.

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
