1.Using special tool
Crankshaft pulley spacer (MD998769), Turn the crankshaft to
bring the
piston in No.1 cylinder to its TDC on the compression
stroke.

2.
caution |
Water or oil on the belt
shortens its life drastically, so the removed
timing
belt, sprocket, and tensioner must be kept free
from oil and water. Do not immerse parts in
cleaning solvent.
|
Mark the belt running direction for reference in
reinstallation.
note |
If there is oil or water on
any part, check the front case oil seal,
camshaft oil seal,
and water pump for leaks.

|
Use special tool End yoke holder
(MB990767), and Pulley holder pin (MB998719), to prevent
the camshaft sprocket from turning, and then loosen the
camshaft sprocket bolt.

|
Use special tool End yoke holder
(MB990767), and Pulley holder pin (MB998719), to prevent
the camshaft sprocket from turning, and then tighten the
camshaft sprocket bolt to the specified torque
of 88 ± 10 N·m.

|
1.Wipe dirt on the
crankshaft sprocket hole using a rag. 2.Using a
rag, wipe dirt on the crankshaft spacer, crankshaft sensing
blade, crankshaft
sprocket, oil pump case and crankshaft sprocket installation
surface. And then perform degreasing.
note |
Degreasing is necessary to
prevent decrease in friction between the mating
surface due to
presence of oil.

|
3.Align the location of pin
and pin hole, and then apply equal force in the direction of
the arrow.
caution |
Do not bend the sensing blade
when installing sprocket.
|
4.Install the crankshaft sprocket to the
crankshaft.

|
If the auto-tensioner rod is fully
extended, set it in the retracted position with the
following procedure. 1.Set the auto-tensioner in a
vice.
|

|
2.Slowly close the vice to
force the rod in until the set hole (A) of the rod is lined
up
with the set hole (B) of the cylinder. 3.Insert a
wire [1.4 mm in diameter] into the set
holes. 4.Remove the auto-tensioner from the
vice.

1.
caution |
If the camshaft sprocket is
rotated with the piston at the top dead center
on the compression stroke of the number 1
cylinder, the valve and piston might
interfere.
|
Move the timing mark of the crankshaft sprocket
three teeth to slightly lower the piston
below the top dead center on the compression stroke of the
number 1 cylinder.

|
2.Line up the timing marks
of the left bank camshaft sprockets. 3.Line up the
timing marks of the right bank camshaft sprockets.
|
![](../../../img/11/AK600633AD00ENG.png)
|
4.Line up the timing marks
of the crankshaft sprockets. 5.Install the timing
belt on each sprocket in the following sequence. (1)
Install the timing belt on the crankshaft sprocket and then
on the idler pulley, while
tightening it to prevent slackness. (2)
Line up the timing marks of the left bank camshaft
sprockets. (3)
Install the timing belt on the water pump pulley, while
taking up the slack. (4)
Install the timing belt on the right bank camshaft
sprocket. (5)
Install the timing belt on the tensioner pulley.
|

|
6.Lightly press the
tensioner pulley against the belt and temporarily tighten
the center
bolt. 7.Check to see that the timing marks of all
the sprockets are in a alignment.
|

|
8.Using special tool Crank
pulley spacer (MD998769), rotate the crankshaft a quarter of
a turn counterclockwise. Then rotate it back clockwise to
verify that all the timing marks are
in alignment.
|

|
9.Mount special tool
Tensioner wrench (MD998767) and torque wrench on the
tensioner pulley. 10.Torque it to 4.4 N·m
with the torque wrench. 11.While holding the
tensioner pulley in position, tighten the center bolt to the
specified
torque of 48 ± 6 N·m. 12.Rotate the
crankshaft two turns clockwise and leave it alone for
approximately five
minutes.
|

|
13.Check to see whether the
metal wire inserted when the auto-tensioner was installed
can
be removed without any resistance. If the metal wire can
be removed without any resistance, it means that the belt
has a
proper tension. Therefore, remove the metal wire. In this
condition, check that the projection
of the rod of the auto-tensioner is within the standard
value. Standard value: 4.8 - 5.5
mm 14.If the metal wire offers resistance
when removed, repeat the previous steps 9 through
12 until a proper belt tension is obtained.
