2. Check for clearance between the piston ring and ring
groove. If it exceeds the limit, replace the ring or piston, or
both.
Standard value:
Number 1: 0.03
− 0.07 mm (0.0012 − 0.0027 inch)
Number 2: 0.02
− 0.06 mm (0.0008 − 0.0023 inch)
Limit: 0.1 mm (0.003 inch)
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: 0.15
− 0.30 mm (0.006 − 0.012 inch)
Number 2: 0.28
− 0.43 mm (0.011 − 0.017 inch)
Oil: 0.10
− 0.40 mm (0.003 − 0.015 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>
1. Remove oil from the crankshaft pin and the connecting rod
bearing.
2. Cut plastic gauging material to the same length as the width
of the bearing and place it on the pin, 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 plastic gauging material at its
widest part by using a scale printed on the plastic gauging
material package.
Standard value: 0.02
− 0.05 mm (0.0008 − 0.0019 inch)
Limit: 0.1 mm (0.003 inch)

INSTALLATION
1. Install the two thrust bearings in the number 3 bearing bore
in the cylinder block. 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 grooved side
facing toward the crankshaft web.
.
>>C<< CRANKSHAFT BEARING INSTALLATION
When bearing replacement is required, select and install the
correct bearing by the following procedure.
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 marks of
its journals are 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.
For example, if the crankshaft journal outside diameter identifi-
cation mark is "0" and cylinder block bearing bore identification
mark is "1," select a bearing whose identification mark is "2" for
number 1, 2, 4 and 5, and a bearing whose identification mark
is "1" for number 3.
If there is no identification mark on the crankshaft, measure the
journal outside diameter and select a bearing appropriate for
the measured value.
3. Install the bearings having an oil groove to the cylinder
block.
4. Install the bearings having no oil groove to the bearing cap.
