>>C<< IDLER PULLEY INSTALLATION

CAUTION

Because of the shallow hexagon hole of the hexagon 
socket head bolt, firmly insert the tool and carefully work 
not to damage the hexagon hole.
Install the idler pulley using a hexagon wrench with 8 mm width 
across flats.

.

>>D<< TIMING BELT INSTALLATION

CAUTION

Remove and install the timing belt, aligning the timing 
marks of the crankshaft sprocket and the camshaft 
sprocket with the Number1 at the Top Dead Center of the 
compression stroke.
1. Check the timing marks of the crankshaft sprocket and the 

camshaft sprocket are aligned with the Number1 at the Top 
Dead Center of the compression stroke. If they are not, align 
the timing marks again, paying attention to the interference 
between the valve and the piston.

2. Install the timing belt on each sprocket in the following 

sequence.

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

on the water pump 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 idler 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.

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

a alignment.

4. Using special tool MD998716, rotate the crankshaft a 

quarter of a turn counterclockwise. Then rotate it back 
clockwise to verify that all the timing marks are in alignment.

5. Pull out the pin of the auto-tensioner.

6. Rotate the crankshaft two turns clockwise and leave it alone 

for approximately five minutes.

7. Check that the projection of the rod of the auto-tensioner is 

within the standard value.

Standard value: 9.1 

− 13.4 mm (0.36 − 0.52 inch)

>>E<< AUTO-TENSIONER INSTALLATION

CAUTION

Always bleed the auto-tensioner of air before installing the 
auto-tensioner. (Refer to Air bleeding method)

TIMING BELT

Replace the belt if any of the following conditions exist:
1. Hardening of rubber backing.

Back side should be glossy without resilience and leave no 
indent when pressed with fingernail.

2. Cracks on rubber back. 
3. Cracks or peeling of canvas.
4. Cracks at bottom of ribs.
5. Cracks on belt sides.

6. Abnormal wear of belt sides. Normal wear is indicated if the 

sides are sharp as if cut by a knife. Abnormal wear is 
indicated if the sides are ragged.

7. Abnormal wear on teeth. 

Initial stage:
Canvas worn (fluffy canvas fibers, rubbery texture 
gone, white discoloration, canvas texture indistinct)
Final stage:
Canvas worn, exposing rubber (tooth width reduced)

8. Missing tooth.

AIR BLEEDING METHOD

CAUTION

• Always use the vertical press and put the auto-ten-

sioner vertically.

• For breakage prevention, Do not apply the load of 5,000 

N (1,124 pound) or more to the rod.

• Do not press the rod beyond Dimension "A" shown in 

the illustration.

1. Set the auto tensioner as shown in the illustration.
2. Press the rod slowly down to the lowest point "A" shown in 

the illustration.

3. Repeat the procedure 2 three times.
4. While the rod is projected at the point "B" shown in the 

illustration, push the rod with 100 

− 200 N (22 − 44 pound). 

Check the enough stiffness. If the stiffness is not enough, 
replace the auto tensioner.

5. Press the rod slowly down. Put the pin through the hole and 

fix it.

CAUTION

After the air bleeding operation has been completed, do 
not tilt the auto-tensioner to 60

° or more from the right 

angle position.

.

VALVE CLEARANCE ADJUSTMENT

1. Remove the rocker cover and ignition coil.

CAUTION

Rotate the crankshaft clockwise at any time.
2. Turn the crankshaft clockwise, and align the crankshaft 

sprocket timing mark with the position shown in the 
illustration.

3. At that time, check the right and left camshaft sprocket 

timing marks are in position as shown in the illustration.
