Removal & Installation Procedure
1. Unscrew the connecting rod bearing cap bolt and re-
move the bearing cap.
Installation Notice
Tightening Torque
40 NSm (30 lb-ft) + 90°
DMake sure that the upper and lower bearing shells
do not change each other.
DCoat the bearing shell with engine oil.
DInstall the bearing cap according to the consecu-
tive number.
Part No. : 601 030 00 62 2.15 mm
Part No. : 601 030 01 62 2.20 mm
Part No. : 601 030 02 62 2.25 mm
Part No. : 601 030 03 62 2.30 mm
Part No. : 601 030 04 62 2.40 mm
2. Unscrew the crankshaft bearing cap bolts and sepa-
rate the upper and lower bearing shells and thrust
washers.
Installation Notice
Tightening Torque
55 NSm (41 lb-ft) + 90°
DRemove the bearing cap from front (pulley side) to
rear.
DMake sure that the upper and lower bearing shells
do not change each other and coat with engine oil.
DThe oil grooves (arrows) in the thrust washers
must face outward and insert the thrust bearing
into the bearing cap.
DThere are five kinds of thrust washers by thick-
ness. 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 ro-
tating condition of the crankshaft.
Installation Notice
DMake 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).
DAssemble so that the projected part of the cap and
crankcase face the same direction.

Removal Procedure
1. Position the number 1 cylinder to ATDC 20°.
Notice:Remove the oil filler cap at adjustment position,
and check whether the intake camshaft cam’s lobe (ar-
row) stays in the upper side.
2. Cover the generator with a clean cloth.
3. Release the tension by unscrewing the screw plug
once.
Notice:In case that the tension is reduced by unscrew-
ing 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 the original position and the
tension gets exceeded.
