Remove the cylinder heae cover.
(Refer to Cylinder Heae Assembly - "Cylinder
Heae Cover") |
2. |
Remove the timing chain cover.
(Refer to Timing System - "Timing Chain
Cover") |
3. |
Remove the timing chain.
(Refer to Timing System - "Timing
Chain") |
4. |
Remove the intake CVVT assembly (A) and
exhaust CVVT assembly (B).
When removing the CVVT assembly bolt,
prevent the camshaft from rotating by using a wrench at
position (A).

Continuous Variable
Valve Timing (CVVT) Assembly |
1. |
Inspect the Continuous variable valve timing
(CVVT) assembly.
(1) |
Fix the Continuous variable valve timing
(CVVT ) with its camshaft in a
vice. |
(2) |
Check that the CVVT assembly will not
turn. If it is not turned, it is in normal
condition. |
(3) |
Apply vinyl tape to all the parts except
the one hole. |
(4) |
Using an air gun, apply the pressure,
147.10kpa (1.5kg/cm², 21.33psi) in the hole.
This makes the lock pin in maximum
retarded state released.

Using an air gun, apply the
pressure, 147.10kpa (1.5kg/cm², 21.33psi) in the
hole. This makes the lock pin in maximum retarded
state released. |
• |
After releasing the pin, you
can turn the CVVT assembly for advance by
hand. |
• |
If there was too much air
leakage, the pin can not be
released. | | |
(5) |
Under the condition of 3), turn the CVVT
assembly to the advance angle side with your
hand.
Depending on the air pressure, the CVVT
assembly will turn to the advance side.
Also, if the air pressure that was
applied was insufficient because of the air leakage from the
port, the lock pin may not release
properly. |
(6) |
Except the position where the lock pin
meets at the maximum delay angle, let the CVVT assembly turn
back and forth and check the movable range and that there is
no interference.
Standard : Movable smoothly in the range
about 25° |
(7) |
Turn the CVVT assembly with your hand
counterclockwise and lock it at the maximum delay angle
position. | |
1. |
Install the intake CVVT assembly (A) and
exhaust CVVT assembly (B).
Tightening
torque :
63.7 ~ 73.5N.m (6.5 ~ 7.5kgf.m, 47.0 ~
54.2lb-ft)
|
When installing the CVVT assembly bolt,
prevent the camshaft from rotating by using a wrench at
position
(A). | |
2. |
Install the timing chain.
(Refer to Timing System - "Timing
Chain") |
3. |
Install the timing chain cover.
(Refer to Timing System - "Timing Chain
Cover") |
4. |
Install the cylinder head cover.
