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.

|
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

|
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.
