3. Install the valve timing belt as follows:

(1) Pass the valve timing belt around the

crankshaft camshaft drive sprocket, the engine
oil pump sprocket and the timing belt idler
pulley in that order.

(2) Pass the valve timing belt around the exhaust-

side camshaft sprocket, and hold the valve
timing belt with paper clip.

(3) Use two wrenches to align the timing mark on

the rocker cover with that on the camshaft
sprocket. Pass the valve timing belt around the
inlet-side camshaft sprocket.

(4) Hold the valve timing belt with paper clips.
(5) Pass the valve timing belt around the timing

belt tensioner pulley.

CAUTION

Incorporate the valve timing belt. Then apply
reverse rotation (anti-clockwise rotation)
pressure to the cam shaft sprocket. Re-check to
see that each timing mark is aligned while the
tension side of the belt is tight.

(6) Remove the two paper clips.

4. Turn the timing belt tensioner in the direction

shown using special tool tensioner wrench
(MD998767) to apply tension to the valve timing
belt. Then pre-tighten the timing belt tensioner
pulley.

5. Check that the timing marks are aligned.

6. Remove the bolt inserted in Step 2 above, then

assemble the cylinder block plug.

7. Tighten the cylinder block plug to the specified

torque.

Tightening torque: 30

8. Adjust the valve timing belt tension.

>>G<< VALVE TIMING BELT TENSION
ADJUSTMENT

1. Set special tool adjusting bolt (MD998738) when

removing the valve timing belt.

CAUTION

Always screw in special tool by hand, since use
of a spanner or other tools may damage the wire
or pin inserted in the timing belt tensioner
adjuster.

2. Gradually screw in special tool until the wire or pin

inserted in the timing belt tensioner adjuster lightly
moves.

3. Turn the crankshaft 1/4 turn anti-clockwise.
4. Turn the crankshaft in the clockwise direction until

you align each timing mark to set No.1 cylinder to
TDC of its compression stroke.

5. Loosen the timing belt tensioner pulley mounting

bolt.

CAUTION

When tightening the mounting bolt, ensure that
the timing belt tensioner pulley does not rotate
with the bolt. Allowing it to rotate with the bolt
can cause deficient tension of the belt.

6. With special tool tensioner wrench (MD998767)

and torque wrench, apply tension torque 3.5 N

¼

and tighten the timing belt tensioner pulley
mounting bolt to the specified torque.

Tightening torque: 48

–

7. Remove wire or pin inserted to timing belt

tensioner.

8. Remove the special tool adjusting bolt

(MD998738), and install the rubber plug to the
timing belt under cover.

9. Rotate the crankshaft clockwise two turns, and

leave it for about 15 minutes.

10.Insert wire or pin removed in Step 7 again, and

ensure that it can be pulled out easily. When wire
or pin can be easily removed, appropriate tension
is applied on timing belt. In this case, remove wire
or pin.

If the projection of timing belt tensioner adjuster
rod is within the standard value, appropriate
tension is applied.

Standard value (A): 3.8

-

4.5 mm

11.If wire or pin cannot be easily pulled out, repeat

Step 1 through Step 9 to reach proper valve timing
belt tension.

CAUTION

Always check the tightening torque of the crank
shaft pulley centre bolt when turning the crack
shaft pulley centre bolt anti-clockwise. Re-
tighten if it is loose.

12.Check again that the timing marks on sprockets

are aligned.

>>H<< END CAP INSTALLATION

CAUTION

Always replace the end cap with new parts since
there may be fall-off or sealing defect if the end
cap is re-used.

INSPECTION

TIMING BELT TENSIONER ADJUSTER
CHECK

1. Check for oil leak from seal, and replace it if leak

is detected.

2. Check for wear or damage at the top of the rod.

Replace it, if required.

3. Hold the timing belt tensioner adjuster by hand,

and press the top end of the rod onto the metal
(e.g. cylinder block) under a pressure of 98

-

196

N to measure the movement of the rod.

Standard value: Within 1 mm

A: Length when it is free (not pressed)
B: Length when it is pressed
A

-

B: Movement

4. If the measured value is out of the standard value,

replace the timing belt tensioner adjuster.

BALANCER TIMING BELT TENSION
CHECK

Check the balancer timing belt tension as follows:

1. Apply a pressure of approximately 100 N at the

centre (arrow area) between the sprocket as
shown then inspect whether the deflection is
within the standard value.

Standard value: 5

-

10 mm

2. If not within the standard value, adjust the belt

tension. (Refer to

3

11A

).
