Installation Notice
l
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).
l
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
l
Remove the bearing cap from front (pulley side) to rear.
l
Make sure that the upper and lower bearing shells do
not change each other and coat with engine oil.
l
The oil grooves (arrows) in the thrust washers must face
outward and insert the thrust bearing into the bearing
cap.
l
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.
l
Make sure that the upper and lower bearing shells do
not change each other.
l
Coat the bearing shell with engine oil.
l
Install the bearing cap according to the consecutive
number.

Inspection
1. If the length ‘L’ of the crankshaft bearing cap bolt exceeds
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 crankshaft
bearing.
Notice
l
Measure at 2 points (1, 2).
l
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’is actual average value.
4. Measure and record the diameter of the crankshaft bearing
journal.
Notice
l
Record the mean value when measured at 3 points (A,
B, C).
l
Measure the inner diameter of bearing and the diameter
of journal and if it is out of the standard data, replace
the bearing shell.
