1.
| caution |
Never turn the crankshaft anti-clockwise.
|
Turn the crankshaft clockwise, align the mating marks on the camshaft sprocket with the
mark plates (yellow) on the timing chain to set No.1 cylinder to TDC (Top Dead Centre) of its
compression stroke.
|
|
2.
| caution |
- Do not lock the camshaft using the timing
chain.
- The camshaft sprocket bolt is left threaded, so the arrow indicating its tightening direction
is marked on the bolt head. To loosen this bolt, turn the bolt to the opposite direction of
the arrow.
- The timing chain must be attached to the camshaft sprockets.
|
Hold the hexagonal part of the camshaft with an open end wrench, loosen the camshaft sprocket
bolts, and then remove the camshaft sprockets with the timing chain still attached.
3.Tie up the timing chain and the camshaft sprocket with a cord to prevent the mating
mark misalignment.

1.Camshaft holder No.2 to 5 are the same shape.
2.Be sure to install team in order of the camshaft holder numbers.
|
|
Set each camshaft with its dowel pin at the illustrated.
|
|
1.Camshaft bearing cap No.2 to 5 are the same shape.
2.Be sure to install team in order of the camshaft bearing cap numbers.
3.Check that the bosses and the arrow mark of the camshaft bearing cap are in the position
shown in the figure.
4.Tighten the camshaft bearing cap bolts to the specified torque.
Tightening torque: 19.6 ± 1 N·m

chain.
- The camshaft sprocket bolt is left threaded, so the arrow indicating its tightening direction
is marked on the bolt head.
|
Install the camshaft sprockets to the camshafts with the timing chain attached.
|
|
2.Hold the hexagonal part of the camshaft with an open end wrench in the same manner as
removal.
3.Apply a small amount of engine oil to the camshaft sprocket bolt thread and the flange,
and then tighten to the specified torque.
Tightening torque: 88 ± 10 N·m

|
Place the chain tensioner gasket with its silicone print facing toward the chain tensioner
side.
|
|
1.Raise the cam, and then push in the plunger.
|
|
2.Lock the plunger using a hook.
3.
| caution |
To install the chain tensioner, always push in the plunger.
If you fail to do this, the timing chain will be excessively tensioned, causing damage.
|
Install the chain tensioner to the cylinder head.
4.
| caution |
If the crankshaft is turned anti - clockwise after the
chain tensioner is installed, the plunger will be excessively tensioned, causing the plunger
to go beyond the cam inside the chain tensioner.
|
| note |
If the crankshaft is turned clockwise after the chain tensioner is installed, the plunger
is automatically unhooked. Then its internal ratchet mechanism adjusts the timing chain tension.
|
Turn the crankshaft clockwise.
