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.

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

m, 

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

Tightening torque: 48 

–

 5 N

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.

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

 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
