4) Cylinder Head Gasket
(1) Features
Sealing the cylinder gas pressure - Peak pressure: 190 bar
Minimizing the distortion of engine structure (cylinder head, block): profile stopper, backland
stopper
Material: MLS (Multi Layer Steel), Gasket (3 layers)
Thickness of gasket: 3 types (1.2 /1.3 /1.4 mm) 1.

Features
Major function: Protecting the chain drive system, minor function: Shielding the chain noise.
Install crankshaft front seal and screw plug on the timing gear case cover. ▶

Do not touch the inner lip of crankshaft front seal.
Be careful not to damage the screw thread when removing the lock pin to release the chain
tensioner.
Be careful not to damage the O-ring when installing the screw plug. -

4) Features
Reduced vibration noise from the powertrain by blocking the torsional vibrations
Enhanced vehicle silence and riding comforts: reduced engine torque fluctuation
Reduced shifting shocks
Smooth acceleration and deceleration -

-
5) Advantages
Improved torque response by using 3-stage type spring: Strengthens the torque response in
all ranges (low, medium, and high speed) by applying respective spring constant at each
range.
Stable revolution of the primary and secondary wheel by using planetary gear: Works as
auxiliary damper against spring changes
Less heat generation due to no direct friction against spring surface: Plastic material is
covered on the spring outer surface
Increased durability by using plastic bushing (extends the lifetime of grease) -

6) 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.

10. PISTON/CRANKSHAFT/CYLINDER BLOCK
The crankshaft and the cylinder block convert the compression pressure to the rotating energy.

(3) Functions
Piston transfers the combustion energy from engine to connecting rod. Especially in the direct
injection engine such as D20DTF, it provides the combustion space and largely effects to the
engine performance and exhaust gas.
Piston ring
#1 ring (Top ring) : Prevents the high pressurized combustion gas from leaking into crank
chamber, and prevents the engine oil getting into combustion chamber.
#2 ring: Scrapes the engine oil on the cylinder bore, and prevents the leaked combustion gas
from #1 ring from leaking into the crank chamber.
Oil ring: Scrapes the engine oil on the cylinder bore.
Piston pin
Connects the piston the connecting rod, and transfers the linear movement of piston to
connecting rod to convert it to rotating energy
Snap pin
Locks the piston pin. ▶

(4) Assembling the piston
Install the piston rings with the "Y" mark on
the ring facing upwards.
Position the end gap of #1 ring at 180˚
away from the end gap of #1 ring.
Position the end gap of oil ring at 180˚
away from the end gap of coil spring, and
position the end gap of oil ring at 90˚ away
from the end gap of #2 ring. 1.
