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 -

Description Mode Conditions
Driving mode 2H 2 Wheel drive
(rear wheel)Rear-wheel drive mode. This is used under
normal or high-speed driving conditions on public
roads or highways.
4H 4 Wheel drive
(high speed)This is used under sandy, muddy or snow-
covered road conditions
4L 4 Wheel drive
(low speed)This is used for maximum traction.
When cornering with low speed in 4WD condition,
there could be tire dragging, some
mechanical shocks and resistances in vehicle’s
drive train. These are normal conditions due to
internal resistance in the drive train when the
4WD system is properly working

To make the mode change easily, stop the
vehicle on level ground and turn the mode
switch to the desired position and move the
shift lever to "N"-"R"-"N" while depressing
the brake pedal. For Automatic Transmission:
Stop the vehicle on level ground and move
the gear selector lever into the “N” position.
Turn the switch to the desired position. -
For Manual Transmission:
Stop the vehicle on level ground and move
the gear selector lever into the “N” position.
Then turn the switch to the desired position
while depressing the clutch pedal. -

1. OVERVIEW
The propeller shaft transfers the power through the transmission and transfer case to the
front/rear axle differential carrier (final reduction gear). It is manufactured by a thin rounded steel
pipe to have the strong resisting force against the torsion and bending. Both ends of propeller
shaft are connected to the spider and the center of propeller shaft is connected to the spline to
accommodate the changes of the height and length. The rubber bushing that covers the
intermediate bearing keeps the balance of rear propeller shaft and absorbs its vibration.
Function of propeller shaft ▶
Transmits driving torque.
Compensates the angle change (universal joint / CV joint).
Compensates the axial length change (splines for the slip joint). -
