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.

Checking
Notice
The noise which continues short time during short travel
(frequent starting of the engine) or engine starting after a
long time storage is normal operating conditions. So, it does
not need to be repaired. Determine the malfunctions in valve
clearance compensation device with noise through following
tests. If defective, replace as respectively.
1. Run the engine at more than 3000rpm for approx. 4 minutes.
2. Stop the engine. After 5minutes, check the engine oil level
and adjust if necessary.
3. Remove the cylinder head cover.
4. Check the valve tappets at TDC position of each cylinders.
5. Using a drift, lightly press the valve tappet and measure
clearance between the cam and valve tappet.
Notice
If the clearance exceeds 0.4mm, replace the valve tappet.
6. If a valve tappet moves down too far in comparison to the
others, replace the valve tappet.
7. Rotate the engine and check the remaining valve tappets.
Notice
lUnnecessary rotation of the engine will damage the valve
tappets.
lDo not rotate the engine by using the camshaft sprocket
bolt or to the opposite direction of the engine rotation.
