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 dam-
aged.
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 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 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.
