3. Use special tool to tighten bolts according to the following
procedure (tightening for plastic zone)
(1) According to the sequence specified in the figure,
tighten the bolt to the specified torque 78±2 N·m.
(2) In the reverse sequence of the figure, fully loosen
bolts.
(3) According to the sequence specified in the figure,
tighten bolts to the specified torque 20±2 N·m.
(4) Indicate paint markings on the heads of cylinder head
bolts and cylinder head, and tighten bolts at the angle
of 90 degree in the sequence specified in the figure.
(5) When bolts are tightened at the angle of 90 degree
according to the figure, ensure that the paint markings
on the heads of cylinder head bolts and cylinder head
are standing in line.
Caution
1) When the tightening angle is under 90 degree,
the bolt is not sufficiently tightened.
2) When the tightening angle exceeds the
specified value, remove the bolt and repeat
the same procedure beginning with Step 1.
"CAO-RING/FUEL HIGH PRESSURE HOSE
INSTALLATION
1. Apply small quantity of new engine oil on O-ring.
Caution
Do not let engine oil get into the delivery pipe.
2. Install the fuel high pressure pipe to the delivery pipe

3. In case of not rotating smoothly, remove the fuel high
pressure hose and insert it to the delivery pipe again
after checking damage of the O-ring since there is a
possibility of O-ring engagement.
4. Tighten fuel high pressure hose mounting bolts to the
specified torque.

1. Rotate the crankshaft clockwise and mate timing marks
with each other to position No.1 cylinder at compression
TDC.
Caution
Ensure that the crankshaft always rotates clockwise.
2. Loosen the mounting bolt of the tensioner pulley and
remove the timing belt.
Caution
When the timing belt is reused, use a chalk to indicate
an arrow of rotation direction on the back of the belt
so that it can be re-assembled in the same direction
as before.

"AATIMING BELT B/TIMING BELT B TENSIONER
INSTALLATION
1. Check that timing marks of crankshaft sprocket B and
balancer shaft sprocket are aligned with each other.
2. Install timing belt B to crankshaft sprocket B and balancer
shaft sprocket. Prevent the tension side of the belt from
sagging.
3. Position the center of the timing belt tensioner B at the
center or upper left of the mounting bolt and flange pulley
at the engine front to assemble and fix them temporarily.
4. Adjust the tension of timing belt B.
"BATIMING BELT B TENSION ADJUSTMENT
1. Apply force to the timing belt B tensioner in the direction
indicated by the arrow to give tension torque (3.0±0.4
N·m) to the timing belt B so that the tension side of the
timing belt B can become tense. Maintaining the condition,
tighten the mounting bolt to the specified torque for fixing.
Tightening Torque: 19±3 N·m
Caution
Be careful not to let the tensioner rotate together when
tightening the mounting bolt. If the tensioner rotates
together, belt tension becomes too much.
2. Measure the tension of timing belt B by following
procedures.

(1) Connect the special tool (MB991668) to the MUT-II.
(2) Connect the special tool (MB991704) to the MUT-II
and the battery.
(3) Rotate the crankshaft clockwise for two rounds to
position No.1 cylinder at compression TDC and check
that timing marks of each sprocket are aligned with
each other.
(4) Select “Belt Tension Measurement” from the menu
screen of the MUT-II.
(5) Hold the special tool (MB991668) to the middle of
the belt between sprockets (at the place indicated
by the arrow) as shown in the illustration about 10
- 20 mm away from the rear surface of the belt and
so that it is perpendicular to the belt (within an angle
of±15_).
(6) Gently tap the middle of the belt between sprockets
(the place indicated by the arrow) with your finger
as shown in the illustration and check that the vibration
frequency of the belt is within the standard value.
Caution
1) If strong gusts of wind blow against the
microphone or if there are any loud sources
of noise nearby, the values measured by the
microphone may not correspond to actual
values.
2) If the microphone is touching the belt while
the measurement is being made, the values
measured by the microphone may not
correspond to actual values.

Apply a force of approx.100N to the middle (arrow part)
of pulley shown in the figure, and check that the deflection
is within the standard value.
3. If it is outside the standard value, re-adjust belt tension.

"CACRANKSHAFT SENSING BLADE/CRANKSHAFT
SPROCKET INSTALLATION
1. Clean and degrease the crankshaft sensing blade and
the crankshaft sprocket mounting surfaces of the
crankshaft sprocket and the crankshaft.
2. Install the crankshaft sensing blade and crankshaft
sprocket to the direction as shown in the illustration.
3. Clean the tapped hole of the crankshaft.
4. Position the chamfered side of the washer to the direction
as shown in the illustration and install to the crankshaft
bolt.
5. Apply a small quantity of engine oil to the contact surface
and the threads of crankshaft bolts.
6. Use the special tool to hold the crankshaft sprocket and
tighten the the crankshaft bolt to the specified torque
in the same way as that for removal.
Tightening Torque: 162±5 N·m
"DAAUTO-TENSIONER INSTALLATION
1. If the auto-tensioner rod is being extended, set according
to the following procedure.
(1) Use a press or a vise to compress the rod of the
auto-tensioner slowly and align the mounting hole
A of the rod with the mounting hole B of the tensioner
cylinder.
Caution
Ensure that the operation should be done slowly
because quick compression could damage a rod.
(2) Insert a wire or etc. into the mated mounting hole.
NOTE
If the automatic tensioner is replaced with a new one,
the automatic tensioner comes with a new pin.
2. Install the auto-tensioner to the engine and tighten the
mounting bolt to the specified torque. Do not remove
a wire or a pin before completing timing belt tension
adjustment.

"FATIMING BELT INSTALLATION
1. Check that timing marks of camshaft sprocket, crankshaft
sprocket, and oil pump sprocket are aligned with each
other.
2. After aligning the timing marks of the oil pump sprocket,
remove the cylinder block plug and insert a Phillips screw
driver with a shaft diameter of 8 mm through the plug
hole to check that the shaft of the screw driver can be
inserted for 60 mm or more. If the screw driver makes
contact with the balancer shaft and can be inserted for
only 20 - 25 mm, turn the sprocket for one round and
align timing marks again to check that screw driver can
be inserted for 60 mm or more. Do not take the screw
driver out before completing installation of the timing belt.
3. Position the timing belt without having any slack at the
tension side of the belt.
(1) Hook the timing belt to the crankshaft sprocket, the
oil pump sprocket, and the idler pulley in the sequence.
