3. Insert the piston ring into the cylinder bore. Force the ring
down with a piston, the piston crown being in contact with
the ring, to correctly position it at right angles to the cylinder
wall. Then, measure the end gap with a feeler gauge.
If the ring gap is excessive, replace the piston ring.
Standard value:
Number 1: 0.30
− 0.45 mm (0.012 − 0.017 inch)
Number 2: 0.45
− 0.60 mm (0.018 − 0.023 inch)
Oil: 0.20
− 0.60 mm (0.008 − 0.023 inch)
Limit:
Number 1, Number 2: 0.8 mm (0.03 inch)
Oil: 1.0 mm (0.03 inch)

CRANKSHAFT PIN OIL CLEARANCE
<PLASTIC GAUGING MATERIAL METHOD>
The crankshaft oil clearance can be measured easily by using
plastic gauging material, as follows:
1. Remove oil from the crankshaft pin and the bearing inner
surface.
2. Cut plastic gauging material to the same length as the width
of the bearing and place it on the pin in parallel with its axis.
3. Install the connecting rod cap carefully and tighten the nuts
to the specified torque.
4. Carefully remove the connecting rod cap.
5. Measure the width of the smashed plastic gauging material
at its widest section by using a scale printed on the plastic
gauging material bag.
Standard value: 0.02
− 0.05 mm (0.0008 − 0.0019 inch)
Limit: 0.1 mm (0.003 inch)

>>A<< CRANKSHAFT BEARING INSTALLATION
1. Measure the crankshaft journal diameter and confirm its
classification from the following table. In the case of a
crankshaft supplied as a service part, identification
colors/marks of its journals are painted/stamped at the
positions shown in the illustration.
2. The cylinder block bearing bore diameter identification
marks are stamped at the position shown in the illustration
from left to right, beginning at No.1.
3. From the above table, select a bearing whose size is
appropriate for the crankshaft journal outside diameter.
If the crankshaft journal outside diameter Identification color
is "yellow" and the cylinder block bearing bore Identification
mark is "III," for example, select a bearing whose
Identification color is "green."
If there is no Identification color paint on the crankshaft,
measure the journal outside diameter and select a bearing
appropriate for the measured valve.

4. Install bearings with the groove toward the cylinder block.
5. Install the bearings having no groove to the bearing cap.
.
>>B<< CRANKSHAFT THRUST BEARING INSTALLATION
1. Install the thrust bearing in the No.3 bearing bore in the
cylinder block and in the bearing cap. For easier installation,
apply engine oil to the bearings; this will help hold them in
position.
2. The thrust bearings must be installed with their groove
toward the crankshaft web.
.
>>C<< BEARING CAP/BEARING CAP BOLT INSTALLATION
1. Attach the bearing cap on the cylinder block as shown in the
illustration.
2. Tighten the bearing cap bolts to specified torque in the
sequence shown in the illustration.
Tightening torque: 74
± 4 N⋅m (54 ± 3 ft-lb)
3. Check that the crankshaft rotates smoothly.
