REMOVAL SERVICE POINTS

<<A>> CRANKSHAFT PULLEY REMOVAL

CAUTION

Use only the specified special tools, or a damaged pulley
damper could result.
Use special tools MB990767 and MD998715 to remove the
crankshaft pulley from the crankshaft.

<<B>> TIMING BELT REMOVAL

CAUTION

Never turn the crankshaft counterclockwise.
1. Turn the crankshaft clockwise to align each timing mark and

to set the number 1 cylinder to compression top dead center.

2. If the timing belt is to be reused, chalk an arrow on the flat

side of the belt, indicating the clockwise direction.

3. Loosen the center bolt of the tensioner pulley, then remove

the timing belt.

INSTALLATION SERVICE POINTS

>>A<< AUTO-TENSIONER INSTALLATION
1. While holding the auto-tensioner with your hand, press the

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

−

196 N (22

−

44 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

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

tensioner.

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 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 it 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 on the camshaft sprockets with those

on the rocker cover and the timing mark on the crankshaft
sprocket with that on the engine block as shown in the
illustration.

CAUTION

The camshaft sprocket (right bank) can turn easily due to
the spring force applied, so be careful not to get your
fingers 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 bank)
(4) Water pump pulley
(5) Camshaft sprocket (Right bank)
(6) Tensioner pulley

3. Turn the camshaft sprocket (Right bank) counterclockwise

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

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

the timing belt, then temporarily tighten the center bolt.

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

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

CAUTION

When tightening the center bolt, be careful that the
tensioner 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 tension
torque to the timing belt as shown in the illustration. Then
tighten the center bolt to the specified torque.

8. Turn the crankshaft clockwise twice to align the timing

marks.
