>>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.

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

tensioner.

8. Turn the crankshaft clockwise twice to align the timing

marks.
