1.With the hose installed,
remove the power steering oil pump assembly from the
bracket.
|
|
|
2.After removing the power
steering oil pump assembly, secure it with a cord in the
location where the removal and installation of the valve
timing belt cannot be hindered.
|
|
|
1.With the hose installed,
remove the A/C compressor and clutch assembly from the
bracket.
|
|
|
2.After removing the
A/C compressor and clutch assembly, secure it with a
cord in the location where the removal and installation of
the valve timing belt cannot be hindered.
|
|
1.Use the following special
tools to support the crankshaft pulley:
- Pulley holder (MB991800)
- Pin (MB991802)
2.Loosen the crankshaft pulley centre bolt and
remove the crankshaft pulley washer and crankshaft
pulley.
|
|
1.
| caution |
Never turn the crankshaft
anti-clockwise.
|
Use special tool crankshaft sprocket spacer
(MD998769), turn the crankshaft clockwise to align each
timing mark and to set the number 1 cylinder to compression
top dead centre.
2.If the valve timing belt is to
be reused, chalk an arrow on the flat side of the belt,
indicating the clockwise direction.
3.Loosen the
timing belt tensioner pulley mounting bolt, then remove the
valve timing belt.
|
|
|
If the timing belt tensioner
adjuster pushrod remains fully extended, set according to
the following procedure.
|
|
1.
| caution |
Place the timing belt
tensioner adjuster perpendicular to the jaws of
the vice.
|
Place two dolly blocks in a vice as shown in the
illustration, and then place the timing belt tensioner
adjuster in the vice.
|
|
2.
| caution |
Never compress the pushrod too
fast, or it may be damaged.
|
Slowly compress the pushrod of the timing belt
tensioner adjuster until pin hole A in the pushrod is
aligned with pin hole B in the cylinder.
3.Insert
the setting pin into the pin holes once they are
aligned.
| note |
If replacing the timing belt
tensioner adjuster, the pin will already be
inserted into the pin holes of the new
part.
|
4.
| caution |
Do not remove the setting pin
from the timing belt tensioner
adjuster.
|
Install the timing belt tensioner adjuster to the
engine.
|
|
1.
| caution |
Align the timing mark of
camshaft sprocket on the right bank side with
the timing mark on the "R" mark side of the
cylinder head.
|
Align the timing marks on the camshaft sprockets
with those on the rocker cover and the timing mark on the
crankshaft camshaft drive sprocket with that on the engine
block as shown in the illustration.
|
|
2.
| caution |
- Align the timing mark of camshaft
sprocket on the right bank side with the
timing mark on the "R" mark side of the
cylinder head.
- 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 valve timing belt by the following
procedure so that there is no deflection in the valve timing
belt between each sprocket and pulley.
(1)
Crankshaft camshaft drive sprocket
(2)
Timing belt idler pulley
(3)
Camshaft sprocket (Left bank)
(4)
Water pump pulley
(5)
Camshaft sprocket (Right bank)
(6)
Timing belt tensioner pulley
3.Turn the camshaft
sprocket (Right bank) anti-clockwise until the tension side
of the timing belt is firmly stretched. Check all the timing
marks again.
|
|
4.Use special tool tensioner
wrench (MD998767) to push the timing belt tensioner pulley
into the valve timing belt, then temporarily tighten the
mounting bolt.
|
|
5.Use special tool
crankshaft sprocket spacer (MD998769) to turn the crankshaft
1/4 turn anti-clockwise, then turn it again clockwise
until the timing marks are aligned.
|
|
6.
| caution |
When tightening the mounting
bolt, be careful that the timing belt tensioner
pulley does not turn with the bolt.
|
Loosen the mounting bolt of the timing belt
tensioner pulley. Use special tool (MD998767) and a torque
wrench to apply the tension torque to the valve timing belt
as shown in the illustration. Then tighten the mounting bolt
to the specified
torque.
Standard value: 4.4
N·m <Valve timing belt tension
torque>
Tightening torque: 48 ± 6
N·m
|
|
7.Remove the setting pin
that has been inserted into the timing belt tensioner
adjuster.
8.Turn the crankshaft clockwise twice to
align the timing marks.
|
|
9.Wait for at least five
minutes, then check that the timing belt tensioner adjuster
pushrod extends within the standard value
range.
Standard value (A): 4.8 - 5.5
mm
10.If not, repeat the operation in
steps 1 to 8 above.
11.Check again that the timing
marks of the sprockets are aligned.
|
|
1.Clean the bolt hole in
crankshaft bolt and crankshaft pulley’s seating
surface.
2.Degrease the cleaned seating surface of
the crankshaft pulley
3.Apply an adequate and
minimum amount of engine oil to the thread of the crankshaft
pulley centre bolt and the upper surface of the crankshaft
pulley washer.
|
|
4.Use the following special
tool as during removal to support the crankshaft
pulley:
- Pulley holder (MB991800)
- Pin (MB991802)
5.Tighten the crankshaft pulley centre bolt to
the specified torque.
Tightening torque: 185
N·m
|
|
Install the bolts to the shown
positions, and tighten them to the specified
torque.
