Installation Notice
lMake sure the crankshaft bearing cap properly seated
in place in the crankcase side. When perfectly installed,
the projected part (arrow) locates in the left side (intake
manifold side).
lAssemble so that the projected part of the cap and
crankcase face the same direction.
Removal & Installation Procedure
1. Unscrew the connecting rod bearing cap bolt and remove
the bearing cap.
Installation Notice
2. Unscrew the crankshaft bearing cap bolts and separate the
upper and lower bearing shells and thrust washers.
Installation Notice
lRemove the bearing cap from front (pulley side) to rear.
lMake sure that the upper and lower bearing shells do
not change each other and coat with engine oil.
lThe oil grooves (arrows) in the thrust washers must face
outward and insert the thrust bearing into the bearing
cap.
lThere are five kinds of thrust washers by thickness. Select
the proper washer when repaired.
3. Remove the crankshaft.
4. Installation should follow the removal procedure in the
reverse order.
5. After completion of the installation, check for the rotating
condition of the crankshaft.
lMake sure that the upper and lower bearing shells do
not change each other.
lCoat the bearing shell with engine oil.
lInstall the bearing cap according to the consecutive
number.

4. Turn the intake camshaft adjuster to the direction of camshaft
rotation by hard until it stops and then install the chain.
Notice
lMake sure that the camshaft sprocket and timing chain
are aligned with marks.
lIntake camshaft adjuster should be in retarded position.
5. Install the chain on the exhaust sprocket and tighten the
sprocket bolts.
Notice
7. Rotate the crankshaft 2 revolutions and check followings:
- TDC of no. 1 cylinder : OT
- Alignment between camshaft adjustment hole and
cylinder head surface.
- Alignments between timing chain and sprocket marks.
Notice
lTurn the crankshaft in the direction of engine rotation.
lRead just if not aligned. 6. Install the chain tensioner and tighten it as specified.
Notice lMake sure that the camshaft sprocket and timing chain
are aligned with marks.
lReplace the sprocket bolt with new one.

Adjustment Procedure
1. Position the No.1 cylinder to BTDC 30° .
2. Remove the chain tensioner.
3. Remove the exhaust camshaft sprocket.
4. Align the intake and exhaust camshaft flange hole with the
cylinder head upper surface.
lIntake Side : 3 o’clock direction
lExhaust Side : 9 o’clock direction
5. Secure the intake and exhaust camshaft.
6. Position the piston of No.1 cylinder at TDC (OT) by turning
the crankshaft.
7. Turn the camshaft adjuster of the intake camshaft to the
left as much as possible (cam adjuster ‘retarded’ position).
8. Install the chain to the intake camshaft sprocket.
Notice
Timing chain must be placed on the guide rail in gear case
cover. Tools Required

Inspection
1. Position the No.1 cylinder piston to TDC (OT) by turning
the crankshaft.
Notice
When the OT mark on vibration damper is aligned with timing
gear case cover, the intake and exhaust cam of cylinder
will make the slope to the center and will face up. In this
way, the adjustment hole of the intake and exhaust camshaft
will match in line with the cylinder head upper end, at 3
o’clock, and 9 o’clock direction each other.
2. Check the timing as below procedure;
- Check if the camshaft adjustment hole is positioned to 3
o’clock direction at the intake side and to 9 o’clock
direction at the exhaust side, respectively and align with
the cylinder head mating surface.
- At this condition, check if the OT mark on vibration
damper aligns with the marker on the timing gear case.
