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.

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 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 plastic gauging material at its

widest part by using a scale printed on the plastic gauging
material package.

>>B<< 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 colours/
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, bearing at No.1.

3. For example, if the crankshaft journal outside diameter ID

color is "Yellow " and the cylinder block bearing bore ID
mark is "III," select a bearing whose ID color is "Green."
If there is no ID color paint on the crankshaft, measure the
journal outside diameter and select a bearing appropriate for
the measured value.

4. Install the bearings having a groove to the cylinder block.

5. Install the bearings having no groove to the bearing cap.

>>C<< CRANKSHAFT THRUST BEARING INSTALLATION
1. Install the thrust bearings in the number 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. The two thrust bearings are
different from each other. One has a tab while the other has
no tab. Be careful not to confuse them.
