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.

Inspection
1. If the length ‘L’ of the crankshaft bearing cap bolt ex-
ceeds 63.8mm, replace it.
2. Make sure the crankshaft bearing cap is properly
seated on the cylinder block (arrows).
3. Measure and record the inner diameter of the crank-
shaft bearing.
Notice
DMeasure at 2 points (1, 2).
DMeasure ‘A’, ‘B’ and ‘C’ as shown. If average value of
‘B’ and ‘C’ is less than value ‘A’, then the average val-
ue of ‘B’ and ‘C’ is actual average value. If average
value of ‘B’ and ‘C’ is more than value ‘A’ is actual av-
erage value.
4. Measure and record the diameter of the crankshaft
bearing journal.
Notice
DRecord the mean value when measured at 3 points
(A,B,C).
DMeasure the inner diameter of bearing and the diam-
eter of journal and if it is out of the standard data, re-
place the bearing shell.
