1.
| caution |
Never turn the crankshaft
anti-clockwise.
|
Use special tool crankshaft wrench (MD998716) to
turn the crankshaft clockwise to align
each timing mark and to set the No. 1 cylinder to
compression top dead centre.
|
|
2.Remove the upper mounting
bolt of the timing belt auto-tensioner.
3.
| caution |
The timing belt auto-tensioner
rotates centring on the flange
bolt due to the rod thrust, so please make sure
your finger is not trapped.
|
Loosen the lower mounting bolt of the timing belt
auto-tensioner slowly and slide the
timing belt auto-tensioner slightly. Remove the rod from the
tensioner arm.
4.Remove the lower mounting bolt of
the timing belt auto-tensioner.
|
|
1.Check that the timing
marks of each sprocket are aligned.
2.If the
timing belt is to be reused, chalk an arrow on the flat side
of the belt, indicating
the clockwise direction.
3.Loosen the centre bolt
of the tensioner pulley, then remove the timing
belt.
|
|
1.
| caution |
Always bleed the timing belt
auto-tensioner of air before installing
the timing belt auto-tensioner (Refer to  ).
|
Insert the pin into the rod of the timing belt
auto-tensioner under the following procedures.
(1)
|
|
| caution |
Notable factors
for inserting pin
- Always use the vertical
press and put the timing
belt auto-tensioner
vertically.
- Do not apply the load of
5,000 N or more to the
rod.
- Do not press the rod beyond
the dimension shown in the
illustration.
|
|
Put the timing belt auto-tensioner vertically to the
vertical press not to be in the sideways
direction.
(2)
Slowly close the vice to force the rod in until the hole (A)
of the rod is lined up with
set hole (B) of the cylinder.
(3)
Insert a pin into the set holes.
(4)
Remove the timing belt auto-tensioner from the
vice.
2.Install the timing belt auto-tensioner
with the setting pin, and tighten the mounting
bolts to the specified torque.
Tightening
torque: 23 ± 6 N·m
|
|
3.Align the timing marks on
the camshaft sprockets with those on the timing belt rear
cover
and the timing mark on the crankshaft sprocket with that on
the engine block as shown in the
illustration.
|
|
4.
| caution |
The camshaft sprocket (right
bank) can turn easily due to the spring force
applied, so be careful not to get your fingers
caught.
|
Install the timing belt by the following procedure
so that there is no deflection in the
timing belt between each sprocket and pulley.
(1)
Crankshaft sprocket
(2)
Water pump pulley
(3)
Camshaft sprocket (Left bank)
(4)
Idler pulley
(5)
Camshaft sprocket (Right bank)
(6)
Tensioner pulley
5.Apply the force to the camshaft
sprocket (Right bank) anti-clockwise until the tension
side of timing belt is tight. Check all the timing marks
again.
6.Remove the setting pin that has been
inserted into the timing belt auto-tensioner.
|
|
7.Use special tool
crankshaft wrench (MD998716), turn the crankshaft clockwise
twice to
align the timing marks.
|
|
8.Wait for at least five
minutes, then check that the timing belt auto-tensioner
pushrod
extends within the standard value
range.
Standard value (A): 9.1 - 13.4
mm
9.If not, repeat the operation in steps
1 to 8 above.
10.Check again that the timing marks
of the each sprockets are aligned.
|
|
1.Tighten the accessory
mount stay bolts to the specified torque in the order shown
in the
figure.
Tightening torque: 20 ± 5
N·m
