REMOVAL SERVICE POINTS

.

<<A>> TIMING BELT REMOVAL

CAUTION

Water or oil on the belt shortens its life drastically, so the
removed timing belt, sprocket, and tensioner must be kept
free from oil and water. Do not immerse parts in cleaning
solvent.
Mark the belt running direction for reference in reinstallation.
NOTE: If there is oil or water on any part, check the front case
oil seal, camshaft oil seal, and water pump for leaks.

.

<<B>> CAMSHAFT SPROCKET BOLT REMOVAL
Use special tools MB990767 and MD998715 to prevent the
camshaft sprocket from turning, and then loosen the camshaft
sprocket bolt.

INSTALLATION SERVICE POINTS

.

>>A<< CAMSHAFT SPROCKET BOLT INSTALLATION

>>B<< CRANKSHAFT SENSING BLADE/CRANKSHAFT
SPACER/CRANKSHAFT SPROCKET INSTALLATION
1. Clean the hole in the crankshaft sprocket.
2. Clean and degrease the mating surfaces of the crankshaft

sprocket, sensing blade, and spacer.
NOTE: Degreasing is necessary to prevent decrease in fric-
tion on the mating surfaces.

3. Align the location of pin and pin hole, and then apply equal

force in the direction of the arrow.

CAUTION

Do not bend the sensing blade when installing sprocket.
4. Install the crankshaft sprocket to the crankshaft.

.

>>C<< AUTO-TENSIONER INSTALLATION
If the auto-tensioner rod is fully extended, set it in the retracted
position with the following procedure.
1. Set the auto-tensioner in a vice.

2. Slowly close the vice to force the rod in until the hole (A) of

the rod is lined up with set hole (B) of the cylinder.

3. Insert a wire [1.4 mm (0.06 inch) in diameter] into the set

holes.

4. Remove the auto-tensioner from the vice.

>>D<< TIMING BELT INSTALLATION

CAUTION

If the camshaft sprocket is rotated with the piston at the
top dead center on the compression stroke of the number
1 cylinder, the valve and piston might interfere.
1. Move the timing mark of the crankshaft sprocket three teeth

to slightly lower the piston below the top dead center on the
compression stroke of the number 1 cylinder.

2. Line up the timing marks of the left bank camshaft

sprockets.

3. Line up the timing marks of the right bank camshaft

sprockets.

4. Line up the timing marks of the crankshaft sprockets.
5. Install the timing belt on each sprocket in the following

sequence.

(1) Install the timing belt on the crankshaft sprocket and then

on the idler pulley, while tightening it to prevent
slackness.

(2) Line up the timing marks of the left bank camshaft

sprockets.

(3) Install the timing belt on the water pump pulley, while

taking up the slack.

(4) Install the timing belt on the right bank camshaft sprocket.
(5) Install the timing belt on the tensioner pulley.

6. Lightly press the tensioner pulley against the belt and

temporarily tighten the center bolt.

7. Check to see that the timing marks of all the sprockets are in

a alignment.
