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.
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.

Inspection
1. If the length ‘L’ of the crankshaft bearing cap bolt
exceeds 63.8 mm, 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
crankshaft bearing.
Notice:
•
Measure at 2 points (1, 2).
•
Measure ‘A’,‘B’and ‘C’ as shown. If 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’, then the value ‘A’ is actual
average value.
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.
