<<C>> OIL PUMP SPROCKET REMOVAL

1. Remove the plug on the left side of cylinder block.

2. Insert a crosspoint screwdriver (shank diameter 8

mm) to prevent the counterbalancer shaft from
rotating.

3. Remove the flange bolt.
4. Remove the oil pump sprocket.

<<D>> CRANKSHAFT BOLT REMOVAL

1. Hold the drive plate with the special tool Flywheel

stopper (MD998781).

2. Remove the crankshaft bolt.

<<E>> CRANKSHAFT SPROCKET
REMOVAL

Use the special tool Crankshaft sprocket puller
(MD998778) if the sprocket is stuck and hard to
remove.

<<F>> TIMING BELT "B" REMOVAL

CAUTION

Water or oil on the belt shortens its life drasti-
cally, so the removed timing belt, sprocket, and
tensioner must be free from oil and water. These
parts should not be washed or immersed in sol-
vent. 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."

<<G>> COUNTERBALANCER SHAFT
SPROCKET REMOVAL

1. Use the special tool Sprocket stopper

(MD998785) to prevent the counterbalancer shaft
sprocket from rotating.

2. Remove the counterbalancer shaft mounting bolt.

the hexagonal portion of the camshaft.

INSTALLATION SERVICE POINTS
>>A<< CAMSHAFT SPROCKET BOLT
INSTALLATION

Tighten the camshaft sprocket bolt to 88

± 10 N⋅m

while preventing the camshaft from rotation using a
wrench fitted on the hexagonal portion of the cam-
shaft.

>>B<< V.V.T. SPROCKET / V.V.T.
SPROCKET BOLT INSTALLATION

1. Apply minimum amount of engine oils adequately

to the following portions.

• All directions of camshaft top

• Inner and outer surfaces of place in which V.V.T.

sprocket is inserted

• Threads and top seat of V.V.T. sprocket bolt

• V.V.T. sprocket bolt seat

2. Install the V.V.T. sprocket.

3. Firmly and deeply insert the V.V.T. sprocket, and

then confirm the V.V.T. sprocket is not rotated,
holding the hexagonal portion of the camshaft
with a wrench.

4. Holding the hexagonal portion of the camshaft

with a wrench, tighten the V.V.T. sprocket bolt to
the specified torque of 65

± 5 N⋅m.

5. Holding the hexagonal portion of the camshaft

with a wrench, confirm the V.V.T. sprocket is not
rotated.
NOTE: This shows the V.V.T. sprocket being
locked at the most retarded angle with the inside
pin.

>>C<< ENGINE SUPPORT BRACKET
INSTALLATION

1. Remove thoroughly the old sealant remaining on

the indicated bolt and in its hole.

2. Coat the bolt with sealant, then install and tighten

it.

Specified sealant:

Mitsubishi Genuine Part No.MD970389 or

equivalent

>>D<< CRANKSHAFT SPROCKET "B"
INSTALLATION

Clean and then degrease the crankshaft sprocket "B"
and the sprocket fitting surface of the crankshaft.
NOTE: Degreasing is necessary to prevent lack of
frictional coefficient between the mating surfaces.

>>E<< SPACER INSTALLATION

CAUTION

If the spacer is opposite in direction to that
shown in the drawing when installed, it will dam-
age the oil seal lip.
1. Smear slightly oil on the outer surface of the

spacer that comes into contact with the oil seal.

2. Install the spacer with the chamfered end toward

the oil seal.

>>F<< COUNTERBALANCER SHAFT
SPROCKET INSTALLATION

1. Use the special tool Sprocket stopper

(MD998785) as shown in the drawing to prevent
the counterbalancer shaft sprocket from rotating.

2. Tighten the sprocket mounting bolt to 45

± 3 N⋅m.

>>G<< TIMING BELT "B" INSTALLATION

1. Align the timing marks on the crankshaft sprocket

"B" and counterbalancer shaft sprocket with the
corresponding timing marks on the oil pump case.

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

sprocket "B" and counterbalancer shaft sprocket.
There should be no slack in the tension section of
the belt.

3. Make sure that the tensioner "B" centre is

positioned as shown in the drawing relative to the
mounting bolt centre.

4. Lift the tensioner "B" with fingers to move it in the

direction of the arrow until the tension section of
the timing belt becomes taut. While keeping the
tensioner "B" in this position, tighten its bolt.
NOTE: When the bolt is tightened, prevent the
tensioner "B" shaft from turning. If the shaft turns,
the belt will be overtightened.

5. Make sure that the timing marks on the oil pump

case and those of the sprockets are all aligned
with each other.

6. Push a central point of the timing belt "B" tension

section lightly with an index to see if it deflects 5

−

7 mm.
