<<E>> TIMING BELT "B" REMOVAL

CAUTION

Water or oil on the belt shortens its life drastically, so the 
removed timing belt, sprocket, and tensioner must be free 
from oil and water. These parts should not be washed or 
immersed in solvent. Replace parts if contaminated.If there 
is oil or water on each part, check the front case oil seals, 
camshaft oil seal and water pump for leaks.
1. Mark the belt running direction for reinstallation.
2. Loosen the tensioner "B" bolt, and then remove the timing 

belt "B."

.

<<F>> COUNTERBALANCE SHAFT SPROCKET REMOVAL
1. Set special tool MD998785 as shown to prevent the 

counterbalance shaft sprocket from turning together.

>>C<< CRANKSHAFT SPROCKET "B" INSTALLATION
Clean and then degrease the front case of the front case, 
crankshaft sprocket "B" and crankshaft surface on which 
sprocket "B" is attached.
NOTE: Degreasing is necessary to prevent decrease in the fric-
tion between contacting surfaces.

.

>>D<< SPACER INSTALLATION
1. Apply a thin coat of clean engine oil to the lip area of the oil 

seal.

2. Install the spacer with the chamfered end facing toward the 

oil seal.

>>E<< COUNTERBALANCE SHAFT SPROCKET 
INSTALLATION
1. Install the counterbalance shaft sprocket and screw the bolt.
2. Install special tool MD998785 as shown in the illustration to 

lock the counterbalance shaft.

3. Tighten the bolt, and then remove the special tool.

Tightening torque: 45

.

>>F<< TIMING BELT "B" INSTALLATION
1. Align timing marks on the crankshaft sprocket "B" and 

counterbalance shaft sprocket with the marks on the front 
case.

2. Install the timing belt "B" on the crankshaft sprocket "B" and 

counterbalance shaft sprocket. There should be no slack on

3. Make sure that the relationship between the tensioner pulley 

center and the bolt center is as shown in the illustration.

4. Move tensioner "B" in the direction of the arrow while lifting 

with your finger to give sufficient tension to the tension side 
of timing belt. In this condition, tighten the bolt to secure 
tensioner "B." When the bolt is tightened, use care to 
prevent the tensioner pulley shaft from turning with the bolt. 
If the shaft is turned with the bolt, the belt will be over 
tensioned.

Tightening torque: 19 

± 3 N⋅m (14 ± 2 ft-lb)

5. Check that timing marks on the sprockets are aligned with 

the timing marks on the front case.

6. With your index finger, press the midway of span on the 

tension side of timing belt "B." The bolt must deflect 5 to 7 
mm (0.20 to 0.28 inch).

>>G<< CRANKSHAFT SENSING BLADE/CRANKSHAFT 
SPROCKET/CRANKSHAFT PULLEY 
WASHER/CRANKSHAFT BOLT INSTALLATION
1. Clean and then degrease the contacting surfaces of the 

crankshaft sprocket, sensing blade and crankshaft.
NOTE: Degreasing is necessary to prevent decrease in the 
friction between contacting surfaces.

2. Clean the bolt hole in the crankshaft, the crankshaft 

contacting surface of the crankshaft sprocket, and the 
washer.

3. Install the sensing blade and the crankshaft sprocket to the 

crankshaft.

4. Apply an appropriately small amount of oil to the threads 

and seating surface of the crankshaft bolt.

5. Install the washer to the crankshaft bolt with its largely 

chamfered side toward the bolt head.
