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 N m) 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.

INSPECTION
AUTO-TENSIONER CHECK
1. Check the sealant for oil leakage and replace if necessary.
2. Check the rod end for wear or damage and replace if
necessary.
3. Measure the deflection of the rod end pressed against
the metal (cylinder block, etc) with the force of 98 - 196
N while holding the auto-tensioner with a hand.
Standard value: Within 1 mm
A: Length in the released state
B: Length in the pressed state
A - B: Deflection
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:
Item
When checked
Vibration frequency Hz
52 - 92
Deflection mm (Reference)
5 - 10
<When using MUT-II>
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.
<When checking the deflection>
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.

REMOVAL AND INSTALLATION
Caution
1. If the vehicle is equipped with the Brembo disc brake, during maintenance, take care not to
contact the parts or tools to the caliper because the paint of caliper will be scratched.
2. Tightening sections indicated in the mark (*) should be finally tightened with engine weight
applied on the body after lightly tightening.
