INSTALLATION

CAUTION

Be sure to use special tool crankshaft sprocket 
spacer (MD998769) when installing the crank-
shaft pulley centre bolt to the crankshaft. If the 
bolt is installed directly to the crankshaft, the tip 
of the bolt and the thread of the crankshaft may 
be damaged.

1. Set the special tool, the crankshaft pulley washer 

and the crankshaft pulley centre bolt to the 
crankshaft camshaft drive sprocket.

3. Incorporate the valve timing belt in the following 

manner so that the tensile force of the belt is not 
lax. 
(1) Pass the valve timing belt around the 

crankshaft camshaft drive sprocket and the 
timing belt idler pulley in that order.

(3) Pass the valve timing belt around the 

camshaft sprocket (inlet side) while aligning 
the timing marks on the rocker cover and the 
camshaft sprocket with a wrench. Then, fix the 
belt with paper clips as shown.

(4) Pass the valve timing belt around the timing 

belt tensioner pulley.

CAUTION

Incorporate the valve timing belt. Then apply 
reverse rotation (anti-clockwise rotation) pres-
sure to the camshaft sprocket. Re-check to see 
that each timing mark is aligned while the ten-
sion side of the belt is right.

(5) Remove the two paper clips.

4. Using special tool tensioner wrench (MD998767), 

turn the timing belt tensioner pulley in the 
direction shown to apply tension to the valve 
timing belt. Then tighten the timing belt tensioner 
pulley mounting bolts temporarily to fix the timing 
belt tensioner pulley.

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. Gradually screw in the special tool to a position in 

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

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

anti-clockwise direction.

6. 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.

7. With special tool tensioner wrench (MD998767) 

and torque wrench, apply tension torque 0.8 N

⋅m 

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

Tightening torque: 48

11.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): 4.8 

− 5.5 mm

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

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

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

− B: Movement

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

replace the timing belt tensioner adjuster.
