1.Insert a flatblade
screwdriver into the release hole of the timing chain
tensioner to
release the latch. 2.Push the tensioner lever by
hand and push in the plunger of the timing chain tensioner
until it hits the bottom. Then, insert a hard wire (piano
wire or the like) of Φ1.5
or hexagonal bar wrench (1.5 mm) into the fixing hole of the
plunger. 3.Remove the timing chain
tensioner.

Hold the hexagonal portion of the
exhaust camshaft with a wrench and loosen the exhaust
camshaft sprocket bolt.

Hold the hexagonal portion of the
inlet camshaft with a wrench and loosen the inlet V.V.T.
sprocket bolt.

1.Assemble the inlet V.V.T.
sprocket assembly in the following
procedure.
- Make sure that the knock pin of the inlet camshaft
assembly is
positioned facing straight upward.
- Apply an appropriate and minimum amount of engine
oil to the circumference of the
tip of the inlet V.V.T. sprocket assembly and the
entire circumference of the area into which
the inlet V.V.T. sprocket assembly is
inserted.
- Slowly insert the inlet V.V.T. sprocket assembly
into the normal position of the
inlet camshaft assembly with its knock pin hole
facing straight upward.
2.Install the V.V.T. sprocket. 3.Make
sure that the V.V.T. sprocket is securely inserted into the
bottom and that the
V.V.T. sprocket does not rotate with the hexagonal portion
of the camshaft secured with a wrench.

4.Hold the hexagonal portion
of the camshaft with a wrench and tighten the inlet V.V.T.
sprocket bolt to the specified torque of 59 ±
5 N·m.

1.Align the timing mark of
the inlet V.V.T. sprocket and the exhaust camshaft
sprocket. 2.Align the crankshaft sprocket keys
with illustrated positions.

|
3.Align the link plate
(orange) with the timing mark of the exhaust camshaft
sprocket and
loop the timing chain.
|

|
4.Align the link plate
(blue) with the timing mark of the inlet V.V.T. sprocket to
loop
the timing chain. Rotate the inlet V.V.T. sprocket by
one or two teeth to align with the timing mark.
|

|
5.Align the timing mark of
the crankshaft sprocket with the link plate (blue) to loop
the
timing chain. Because the timing chain slacks, hold it to
prevent the timing mark from coming off
the link plate.
|

|
6.Make sure that the timing
mark of each sprocket is aligned with the link plate of the
timing chain at all of three locations. 7.Install
the timing chain guide and tensioner lever.

|
1.Install the timing chain
tensioner on the cylinder block and tighten it to the
specified
torque of 10 ±
2 N·m. 2.Remove the hard wire (piano wire or
the like) of Φ1.5 or hexagonal bar wrench
(1.5 mm) from the timing chain tensioner. This enables the
plunger of the timing chain tensioner
to push the tensioner lever to keep the timing chain
tight.
