Removal & Installation Procedure

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).
