CRANKCASE

5-72

EAS25560

DISASSEMBLING THE CRANKCASE

1. Remove:

• Crankcase bolts

TIP

Loosen each bolt 1/4 of a turn at a time, in
stages and in a crisscross pattern. After all of
the bolts are fully loosened, remove them.

• M6

×

35 mm (1.38 in) bolts “1”

• M6

×

50 mm (1.97 in) bolts “2”

• M8

×

110 mm (4.33 in) bolts “3”

2. Remove:

• Left crankcase

ECA13900

Tap on one side of the crankcase with a
soft-face hammer. Tap only on reinforced
portions of the crankcase, not on the
crankcase mating surfaces. Work slowly
and carefully and make sure the crankcase
halves separate evenly.

EAS25580

CHECKING THE CRANKCASE

1. Thoroughly wash the crankcase halves in a

mild solvent.

2. Thoroughly clean all the gasket surfaces

and crankcase mating surfaces.

3. Check:

• Crankcase

Cracks/damage

→

Replace.

• Oil delivery passages

Obstruction

→

Blow out with compressed

air.

EAS4B51032

CHECKING THE TIMING CHAIN

1. Check:

• Timing chain

Damage/stiffness

→

Replace the timing

chain, camshafts and crankshaft assem-
bly as a set.

EAS25700

ASSEMBLING THE CRANKCASE

1. Install:

• Cylinder stud bolts “1”

TIP

For the cylinder stud bolt, embedded height “a”
is the standard value and the tightening torque
is the reference value.

2. Thoroughly clean all the gasket mating sur-

faces and crankcase mating surfaces.

3. Apply:

• Sealant

(onto the crankcase mating surfaces)

TIP

Do not allow any sealant to come into contact
with the oil gallery.

4. Install:

• Dowel pins
• Left crankcase

Cylinder stud bolt
