1. Insert a 12.7 mm (1/2 inch) breaker bar into the square hole

on the drive belt auto tensioner, and rotate it clockwise until
the tensioner touches the stopper.

2. Align hole B with hole A, and insert a 5.0 mm (0.20 inch)

Allen wrench to hold the tensioner. Then loosen the drive
belt, and then remove the drive belt auto tensioner.

<<B>> POWER STEERING OIL PUMP ASSEMBLY / A/C
COMPRESSOR ASSEMBLY REMOVAL
1. Do not disconnect the hoses to remove the pump and

compressor.

2. Support the removed pump and compressor with a wire, etc.

so that they will not get in the way while working.

.

<<C>> CRANKSHAFT PULLEY REMOVAL
Use special tools MB991800 and MB991802 to remove the
crankshaft pulley from the crankshaft.

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 mark the flat side of

the belt with an arrow indicating the clockwise direction.

3. Loosen the center bolt of the tension pulley, and then

remove the timing belt.

INSTALLATION SERVICE POINTS

.

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

of crankshaft sprocket.

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) Tension pulley

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
tensioner 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)
