2. Rotate the crankshaft counterclockwise for 1/4 round.
3. Rotate the crankshaft clockwise and mate timing marks
with each other to position No.1 cylinder at compression
TDC.
4. Loosen the temporarily tightened tensioner pulley
mounting bolt.
5. Use the special tool and torque wrench to apply tension
torque (3.5 Nm) to the timing belt in the direction indicated
in the figure and tighten the tensioner pulley mounting bolt
to the specified torque.
Tightening Torque: 48±5 N·m
Caution
Be careful not to let the tensioner pulley rotate together
when tightening the mounting bolt. If the tensioner
rotates together, belt tension becomes too loose.
6. Remove a wire or a pin inserted during installation of
the automatic tensioner.
7. Remove the special tool installed in the above - mentioned
1 with a hand.
8. Rotate the crankshaft clockwise for two rounds and leave
it alone for approximately 15 minutes.
9. Insert the removed wire or pin in the above - mentioned
6 again to check that it can be removed easily.
If either wire or pin can be removed easily, the timing
belt tension is correct and remove a wire or a pin. Then,
check that projection of the automatic tensioner rod is
within the standard value.
Standard value (A): 3.8 - 4.5 mm
10. If a wire or a pin cannot be easily removed, repeat the
above-mentioned operations 1 - 8 to obtain the correct
timing belt tension.
11. Check that timing marks of each sprocket are aligned
with each other.
Caution
After turning the crankshaft bolt counterclockwise,
always check the tightening torque of the crankshaft
bolt and tighten it again if it becomes loose.

4. If the value is outside the standard value, replace the
auto-tensioner.
TIMING BELT B TENSION CHECK
1. Measure the tension of timing belt B by following
procedures.
Standard value:
ItemWhen checked
Vibration frequency Hz52 - 92
Deflection mm (Reference)5-10

Tap the center of the belt between the pulleys (arrow),
and check that the belt vibration frequency is within the
standard values.
NOTE
For the vibration frequency measurement using the
MUT-II, refer to P11A-37.

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.
2. If it is outside the standard value, re-adjust belt tension.

AD"ENGINE ASSEMBLY REMOVAL
After checking that all the cables, hoses, and harness
connectors have been disconnected, lift the engine with a
chain block slowly and remove the engine assembly located
at the upper engine room.
INSTALLATION SERVICE POINTS
"AAENGINE ASSEMBLY INSTALLATION
Install the engine assembly while checking that none of cables,
hoses, or harness connectors, etc. has been engaged.
"BAENGINE MOUNTING BRACKET AND STOPPER
ASSEMBLY INSTALLATION
1. Support the engine oil pan with a garage jack via a block
of wood cut adjusting the engine position and install the
engine mounting bracket and stopper assembly. Position
the engine mounting stopper so that a mark indicated
by an arrow can face the direction shown in the illustration.
2. Support engine with garage jack.
3. Remove the chain block and hold the engine assembly
with the special tool.(Tool used for removal of transmission
assembly)
"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
rotating in both directions without damaging the O-ring
and check that it rotates smoothly.
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 bolt to the
specified torque.

3. Confirm that the tensioner B centre and bolt centre are
positioned as shown in the illustration.
4. Apply tension on the timing belt by lifting tensioner B
in the direction of the arrow with a finger, and tension
the tension side until it is “tight”. Fix tensioner B in this
state by tightening the bolt.
NOTE
Make sure that the tensioner B shaft does not rotate
when tightening the bolt. If the shaft rotates, the timing
belt becomes too tense.
5. Connect the special tool (MB991704) to MUT-IIand the
battery.
6. Connect the special tool (MB991668) to MUT-II.
7. Rotate the crankshaft clockwise two turns, and align each
timing mark.
8. Select “Belt Tension Measurement” from the MUT-IImenu
screen.
9. Separate the special tool (MB991668) 10 to 20 mm from
the centre back between the sprockets (shown with an
arrow), and hold so that it is vertical (inclination within
±15_) in respect to the belt.
10. Lightly tap the section shown with an arrow with fingers,
and measure the belt vibration frequency. If the results
are deviated from the standard value, loosen the bolt,
tension the belt again, and then measure the vibration
frequency again. Repeat this step until the standard value
is attained. Tighten the bolt when the standard value
is attained.

14. Using the special tool, rotate the tensioner pulley in the
counterclockwise direction to tense the timing belt, and
then fix by temporarily tightening the tensioner fixing bolt.
NOTE
Remove the deflection of the timing belt between the
intake side and exhaust side camshafts.
15. Rotate the crankshaft in the clockwise direction, and set
the timing mark at the No. 1 cylinder compression top
dead centre.
16. Set the special tool, and screw it in until the wire inserted
when the auto tensioner was installed slightly moves.
17. Loosen the tensioner pulley fixing bolt.
Caution
The timing belt will loosen at this time due to the
rotation of the intake and exhaust camshafts, so make
sure that the timing belt does not deviate.
18. Rotate the special tool and torque wrench in the
counterclockwise direction to remove the timing belt
deflection.
19. From that state, return to the position where the torque
wrench scale reads 3.5 N•m, and then tighten the fixing
bolt.
20. Remove the special tool installed in step 16.
21. Rotate the crankshaft two rotations in the clockwise
direction, and let stand for approx. 15 minutes.
22. Confirm whether the wire inserted when the auto tensioner
was installed can be pulled out easily. If it can be removed
easily, the belt tension is appropriate, so remove the wire.
If the auto tensioner rod’s protrusion amount is at the
standard value, the tension is appropriate.
Standard value: 3.8 - 4.5 mm
23. If the wire cannot be pulled out easily, repeat steps 16
to 21, and tense the belt to the appropriate tension.
Caution
When the crankshaft bolt has been rotated in the
counterclockwise direction, always check the crank-
shaft bolt’s tightening torque. If loosen, re-tighten.

INSPECTION
1. TIMING BELT
Inspect each section of the belt in detail, and if any of
the following type of damage is found, replace the belt
with a new part.
(1) Hardening of backface rubber.
The backface is glossy, marks are not made even
when a fingernail is run cross it, and there is no
elasticity.
(2) Cracking of backface rubber.
(3) Cracking of canvas.
(4) Cracking at root.
(5) Cracking on side of belt.
(6) Abnormal wear on side of belt.
NOTE
The state is normal if the cutting surface is neat as
if cut with a sharp knife.
(7) Abnormal wear of teeth.
First stages: Canvas is worn (canvas fibres are raised,
rubber is removed and whitish, and canvas seams
are unclear).
Latter stages: Canvas is worn off, and rubber is
exposed (face width is narrow).
(8) Teeth are missing.
2. AUTO TENSIONER
(1) Check for oil leaks. If any leaks are found, replace.
(2) Check whether the rod end is worn or damaged,
and replace if necessary.
(3) Measure the rod protrusion length. If not at the
standard value, replace the auto tensioner.
