10. FLYWHEEL AND DRIVE PLATE
1) DMF (Dual Mass Flywheel)
The dual mass flywheel, or DMF, eliminates excessive transmission gear rattle, reduces gear
change/shift effort, and increases fuel economy. There is a friction ring located between the inner and
outer flywheel that allows the inner and outer flywheel to slip. This feature is designed to alleviate any
damage to the transmission when torque loads exceed the vehicle rating of the transmission. The friction
ring is the weak spot in the system and can wear out if excessive engine torque loads are applied
through it. The system also has a center support bearing that carries the load between the inner and
outer flywheel, and is fitted with damper springs to absorb shocks.
2) Drive Plate
Drive plate receives the power from the start motor when starting the engine. With this, the drive plate
initially drives the power train system. And, it is connected to the torque converter to transfer the engine
torque to the power train system.Components

3) Inspection of Turbine
Thoroughly check the followings.
Interference: In case where is trace of interference or smallest damage on the compressor wheel
means, most of times, that abrasion has occurred on the journal bearing. Must inspect after the
overhaul.
Oil Leakage: The reason for oil leakage at the compressor section is the air cleaner, clogged by
substances such as dust, causes the compressor inlet negative pressure. -
-
Rotating in high speed at no-load for extended period of time can cause oil leakage to the
compressor section as oil pressure within the center housing gets higher than pressure within the
compressor housing.
Overuse of engine break (especially in low gear) in down hill makes significantly low exhaust gas
energy compared to the time where great amount of air is required during idling conditions of the
engine. Therefore, amount of air in the compressor inlet increases but the turbocharge pressure
is not high, which makes negative pressure at the compressor section causing the oilleakage
within the center housing. a.
b.
No problem will occur with the turbocharger if above conditions are found in early stage but oil
leaked over long period of time will solidify at each section causing to breakout secondary
defects.
Damages by foreign materials: In case where the compressor wheel is damaged by foreign materials
requires having an overhaul. At this time, it's necessary to check whether the foreign materials have
contaminated intake/exhaust manifold or inside of engine.
Must absolutely not operate the turbocharger with the compressor outlet and inlet opened
as it could damage the turbocharger or be hazardous during inspection.

3. LUBRICATION
1)Anti-friction
The oil makes a thin film on the surface of sliding components to reduce the wear due to friction.
2)Cooling
The friction makes the heat on the components. The oil absorbs the heat and radiates it or cools it down.
3) Sealing
The piston ring on the piston seals the cylinder. The oil gets into the clearance in piston ring to secure
the sealing for compression pressure and combustion gas.
4) Anti-corrosion
The oil generates the thin film on the surface of components to prevent the material from contacting with
air, water and corrosive gas.
5) Cleaning
The oil transfers the residue of material due to friction, oxidized substance, and carbonized substance
while circulating in the engine by oil pump.

3) Input/Output for CAN communication
(1) Configuration of CAN (P-CAN/B-CAN)
CAN Topology communicate with system units. There are two types (P-CAN and B-CAN) of
communication according to the communication speed. Instrument cluster, BCM and diagnostic
connector use both types of communication. And, ECU, ABS & ESP, TCU, GCU, E-coupling and EPS
unit use P-CAN communication because it is faster than B-CAN. The terminal resistances are installed in
ECU and BCM.
