1. Unscrew the connecting rod bearing cap bolt and
remove the bearing cap.
Installation Notice
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
separate the upper and lower bearing shells and
thrust washers.
Installation Notice
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 left side (intake manifold side).
•
Assemble so that the projected part of the cap and
crankcase face the same direction.
•
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.
Tightening Torque
40 N•m (30 lb-ft) + 90°
•
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 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
rotating condition of the crankshaft.
Tightening Torque
55 N•m (41 lb-ft)+ 90°

Inspection
1. If the length ‘L’ of the crankshaft bearing cap
bolt exceeds 63.8 mm, replace it.
4. Measure and record the diameter of the crankshaft
bearing journal.
Notice:
•
Record the mean value when measured at 3
points (A,B,C).
•
Measure the inner diameter of bearing and the
diameter of journal and if it is out of the standard
data, replace the bearing shell.
3. Measure and record the inner diameter of the
crankshaft bearing.
Notice:
•
Measure at 2 points (1, 2).
•
M e a s u r e ‘ A ’ , ‘ B ’ a n d ‘ C ’ a s s h o w n . I f
average value of ‘B’ and ‘C’ is less than value
‘A’, then the average value of ‘B’ and ‘C’ is
actual average value. If average value of ‘B’
and ‘C’ is more than value ‘A’ is actual
average value.
2. Make sure the crankshaft bearing cap is properly
seated on the cylinder block (arrows).
