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.

"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.
Tightening Torque: 23±3 N·m

(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.

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.
