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.
