4. Turn the timing belt tensioner pulley in the 

direction shown in the figure using special tool 
tensioner wrench (MD998767) to apply tension to 
the valve timing belt. Then temporarily tighten and 
fix the timing belt tensioner pulley mounting bolt.

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) used 

when removing the valve timing belt.

CAUTION

Always screw in the special tool in with your 
hands, 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 the special tool to a position in 

which the wire or pin inserted in the timing belt 
tensioner adjuster lightly moves. 

3. Turn the crankshaft 1/4 of a revolution in the 

anti-clockwise direction.

4. Turn the crankshaft in the clockwise direction, 

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

to the valve timing belt, and tighten the timing belt

torque.

7. Remove wire or pin inserted to timing belt 

tensioner adjuster.

8. Remove special tool adjusting bolt (MD998738), 

and install the rubber plug to the timing belt under 
cover.

9. Rotate 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 with a light load. 
When wire or pin can be lightly removed, 
appropriate tension is applied on timing belt. In 
this case, remove wire or pin.

Also the projection of timing belt tensioner 
adjuster rod (A) 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 
crankshaft pulley centre bolt when turning the 
crankshaft pulley centre bolt anti-clockwise. 
Re-tighten if it is loose.

12.Check again that the timing marks on sprockets 

are aligned.

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 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 in the 
following procedures.

1. Apply a pressure of approximately 100 N at the 

centre (arrow area) between the sprocket as 
shown in the figure, then inspect whether the 
flexure is within the standard value.

Standard value: 5 

−

 10 mm

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

tension. (Refer to 

P.11C-36

).
