3. Turn the camshaft sprocket counterclockwise until the

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

CAUTION

When tightening the center bolt, be careful that the ten-
sioner pulley does not turn with the bolt.
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.

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 ± 6 N⋅m (36 ± 4 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): 4.8

− 5.5 mm (0.19 − 0.22 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.

>>B<< AUTO-TENSIONER INSTALLATION
1. While holding the auto-tensioner by hand, press the end of

the pushrod against a metal surface (such as the cylinder
block) with a force of 98

− 196 N (72 − 145 pound) and

measure how far the pushrod is pushed in.

Standard value: Within 1 mm (0.04 inch)
A: Length when no force is applied
B: Length when force is applied
A

− B: Amount pushed in

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.

2. If it is not within the standard value, replace the auto-

tensioner.

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.

>>C<< CRANKSHAFT PULLEY INSTALLATION
Use special tools MB991800 and MB991802 to install the
crankshaft pulley.

>>D<< ACCESSORY MOUNT ASSEMBLY INSTALLATION
Install the bolts to the shown positions, and tighten them to the
specified torque.

>>E<< DRIVE BELT AUTO TENSIONER INSTALLATION
1. Install the drive belt auto tensioner with the Allen wrench

inserted.

2. After the drive belt has been installed, remove the Allen

wrench while holding the drive belt auto tensioner with a
socket wrench drive. Then release the drive belt auto
tensioner slowly.
