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.

Caution
When the timing belt B 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.
INSTALLATION SERVICE POINTS
"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.

"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.

(2) Hook the timing belt with exhaust side of the camshaft
sprocket and retain the specified position indicated
in the figure with paper clips.
(3) Use two wrenches to hook the timing belt to the intake
side of the camshaft sprocket while aligning the timing
marks on the rocker cover and camshaft sprocket.
(4) Retain timing belt at the specified positions with paper
clips according to the figure.
(5) Hook the timing bolt to the tensioner pulley.
(6) Remove two paper clips.
Caution
After hooking the timing belt, apply force to the
camshaft sprocket counterclockwise(in left turn)
and reconfirm that each timing mark is in the
proper position while the belt is being stretched.
4. Use the special tool to rotate the tensioner pulley in the
direction indicated in the figure, tighten the timing belt,
and temporarily tighten the mounting bolt of the tensioner
pulley for fixing.
5. Check that each timing mark is properly aligned.
6. Remove the screw driver and install a plug.
7. Adjust timing belt tension.
"GATIMING BELT TENSION ADJUSTMENT
1. After removal of the rubber plug of the timing belt rear
cover, prepare the special tool to insert the special tool
into the position where a wire or a pin inserted during
installation of automatic tensioner can be moved easily.
Caution
Be sure to pressfit the special tool with a hand because
pressfitting the special tool with tools, such as
spanner, and etc. could damage a wire or a pin inserted
into the automatic tensioner.
