CAUTION

• Place the auto-tensioner perpendicular to the jaws of 

the vice.

• If there is a plug at the base of the auto-tensioner, insert 

a plain washer onto the end of the auto-tensioner to 
protect the plug.

3. Place two dolly blocks in a vice as shown in the illustration, 

and then place the auto-tensioner in the vice.

CAUTION

Never compress the pushrod too fast, or the pushrod may 
be damaged.
4. Slowly compress the pushrod of the auto-tensioner until pin 

hole A in the pushrod is aligned with pin hole B in the 
cylinder.

5. Insert the setting pin into the pin holes once they are 

aligned.
NOTE: If replacing the auto-tensioner, the pin will already be 
inserted into the pin holes of the new part.

CAUTION

Do not remove the setting pin from the auto-tensioner.
6. Install the auto-tensioner to the engine.

>>B<< TIMING BELT INSTALLATION
1. Align the timing marks of the camshaft sprocket with those 

of crankshaft sprocket.

CAUTION

The camshaft sprocket (right side) can turn easily due to 
the spring force applied, so be careful not to get your fin-
gers caught.
2. Install the timing belt by the following procedure so that 

there is no deflection in the timing belt between each 
sprocket and pulley.

(1) Crankshaft sprocket
(2) Idler pulley
(3) Camshaft sprocket (Left side)
(4) Water pump pulley
(5) Camshaft sprocket (Right side)
(6) Tension pulley

3. Turn the camshaft sprocket counterclockwise until the 

tension side of the timing belt is firmly stretched. Check all 
timing marks again.

4. Use special tool MD998767 to push the tensioner pulley into 

the timing belt, and then temporarily tighten the center bolt.

5. Use special tool MD998769 to turn the crankshaft 1/4 turn 

counterclockwise and then turn it again clockwise until the 
timing marks are aligned.

CAUTION

When tightening the center bolt, be careful that the ten-
sioner pulley does not turn with the bolt.
6. Loosen the center bolt of the tensioner pulley. Use special 

tool MD998767 and a torque wrench to apply the standard 
torque to the timing belt as shown in the illustration. Then 
tighten the center bolt to the specified torque.

Standard value: 4.4 N

⋅m (39 in-lb) <Timing belt ten-

sion torque>

Tightening torque: 48 N

⋅m (35 ft-lb)

7. Remove the setting pin that has been inserted into the 

auto-tensioner.

8. Turn the crankshaft two turns clockwise to align the timing 

marks.

9. Wait for at least five minutes, and then check that the 

auto-tensioner pushrod extends within the standard value.

Standard value (A): 3.8 

− 5.0 mm (0.15 − 0.20 inch)

10.If no, repeat the operation in steps (5) to (9) above.
11.Check again that the timing marks of each sprocket are 

aligned.
