able tool, install piston and connecting rod assembly with front
mark on piston head facing toward the front side of engine.
CAUTION:
When installing piston and connecting rod assembly, pre-
vent the big end of connecting rod from interfering with
oil jet.

Always use either the angle wrench (special service tool)
or protractor during angular tightening. Avoid tightening
based on visual checks alone.

After tightening nuts, make sure that crankshaft rotates
smoothly.

Check connecting rod side clearance. Refer to EM-226,
"CONNECTING ROD SIDE CLEARANCE" .

How to Select Piston and BearingEBS00ODY
DESCRIPTION

The identification grade stamped on each part is the grade for the dimension measured in new condition.
This grade cannot apply to reused parts.

For reused or repaired parts, measure the dimension accurately. Determine the grade by comparing the
measurement with the values of each selection table.

For details of the measurement method of each part, the reuse standards and the selection method of the
selective fitting parts, refer to the text.
HOW TO SELECT PISTON
When Using New Cylinder Block
1. Identify the cylinder bore grade (No. 1, 2, or 3) on LH surface at
the rear of cylinder block.
2. Select piston of the same grade.

The part No. of piston is specified together with piston pin as
an assembly.
When Re-using an Old Cylinder Block
1. Measure cylinder bore inner diameter. Refer to EM-230, "Cylinder Bore Inner Diameter" .
2. Referring to “Cylinder bore inner diameter” in “Piston Selection Table”, determine the bore grade.
3. Select piston of the same grade.

HOW TO SELECT CONNECTING ROD BEARING
When Using New Crankshaft and Connecting Rod
1. Identify the pin diameter grade (No. 0, 1, or 2) on front surface of
crankshaft.
2. Select connecting rod bearings of the same grade.
NOTE:
There is no grading for the inner diameter of the big end of the
connecting rod.
When Re-using the Removed Crankshaft and Connecting Rod
1. Measure the inner diameter of the big end of connecting rod and make sure it is within the specified
range. Refer to EM-228, "
CONNECTING ROD BIG END INNER DIAMETER" .
2. Measure the outer diameter of the crankshaft pin. Refer to EM-231, "
CRANKSHAFT PIN OUTER DIAME-
TER" .
3. Determine the crankshaft pin grade by comparing the measurement with the values under the column
“Crankshaft pin outer diameter” in “Selection Table of connecting Rod Bearing”.
4. Choose bearings of the same grade.

CRANKSHAFT END PLAY

Using dial gauge, measure crankshaft travel amount by moving
the crankshaft forward or backward.

If the value exceeds the limit, replace thrust bearings with new
ones and measure again.
If the measurement exceeds the limit again, replace crankshaft
with a new one.
CONNECTING ROD SIDE CLEARANCE

Using feeler gauge, measure side clearance between connect-
ing rod and crankshaft arm.

If measured value exceeds the limit, replace connecting rod and
repeat measurement.
If measured value still exceeds the limit, replace crankshaft.
PISTON TO PISTON PIN CLEARANCE
Piston Pin Bore Diameter
Using inside micrometer, measure piston pin bore diameter.
Piston Pin Outer Diameter
Using micrometer, measure piston pin outer diameter.
Calculation of Piston to Piston Pin Clearance
(Piston pin clearance) = (Piston pin bore diameter) − (Piston pin outer diameter)

If out of the standard, replace piston/piston pin assembly.Standard : 0.10 - 0.25 mm (0.0039 - 0.0098 in)
