>>A<< INTAKE V.V.T. SPROCKET BOLT INSTAL-
LATION
1. Assemble the intake 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 intake V.V.T. sprocket
assembly and the entire circumference of the area into
which the intake V.V.T. sprocket assembly is inserted.
• Slowly insert the intake 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 intake V.V.T. sprocket bolt to the specified
tightening torque.
Tightening torque: 59
± 5 N⋅m (44 ± 3 ft-lb)

4. Align the link plate (blue) with the timing mark of the intake
V.V.T. sprocket to loop the timing chain.
Rotate the intake 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.
