Installation Notice
Make sure the crankshaft bearing cap properly seated
in place in the crankcase side. When perfectly installed, the projected part (arrow) locates in the leftside (intake manifold side).
Assemble 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
Remove the bearing cap from front (pulley side) to
rear.
Make sure that the upper and lower bearing shells do
not change each other and coat with engine oil.
The oil grooves (arrows) in the thrust washers must
face outward and insert the thrust bearing into the bearing cap.
There 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.
Make sure that the upper and lower bearing shells do
not change each other.
Coat the bearing shell with engine oil.
Install the bearing cap according to the consecutive
number.

Notice Remove the oil filler cap at adjustment position, and check whether the intake camshaft cam ’s lobe (arrow) stays in the
upper side.
2. Cover the alternator with a clean cloth.
3. Release the tension by unscrewing the screw plug once.
NoticeIn case that the tension is reduced by unscrewing the screw
plug, reinstall after completely removing the chain tensioner.If the chain tensioner is tightened again without completely reducing its tension, then the snap ring doesn ’t return to
