>>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
± 3 N⋅m (33 ± 2 ft-lb)
.
>>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

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).

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
