How to Select Piston and Bearing ABS00E9Q
DESCRIPTION
*: For the service parts, the grade for fitting cannot be selected between piston pin and connecting rod. (Only “0” grade is a vailable.) The
information at the shipment from the plant is described as a reference.
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 New Cylinder Block is Used:
Check the cylinder bore grade (“1”, “2” or “3”) on the rear upper side
between cylinder block banks, and select piston of the same grade.
NOTE:
Piston is available with piston pin as a set for the service part. (Only
“0” grade piston pin is available.)

When Cylinder Block is Reused:
1. Measure the cylinder bore inner diameter. Refer to EM-266, "Cylinder Bore Inner Diameter" .
2. Determine the bore grade by comparing the measurement with the values the “Cylinder bore inner diame- ter” of the “Piston Selection Table”. Select piston of the same grade.

Unit: mm (in)
NOTE:
Piston is available together with piston pin as assembly.
Piston pin (piston pin hole) grade is provided only for the parts installed at the plant. For service parts, no
piston pin grades can be selected. (Only “0” grade is available.)
No second grade mark is available on piston.
HOW TO SELECT CONNECTING ROD BEARING
When New Connecting Rod and Crankshaft are Used:
Check pin diameter grade (“0”, “1” or “2”) on front of crankshaft, and
select connecting rod bearing of the same grade.
NOTE:
There is no grading for connecting rod big end diameter.
When Crankshaft and Connecting Rod are Reused:
1. Measure the connecting rod big end diameter. Refer to EM-264, "CONNECTING ROD BIG END DIAME-
TER" .
2. Make sure that the connecting rod big end diameter is within the standard value.
3. Measure the crankshaft pin journal diameter. Refer to EM-268, "
CRANKSHAFT PIN JOURNAL DIAME-
TER" .
4. Determine the grade of crankshaft pin diameter grade by corresponding to the measured dimension in “Crankshaft pin journal diameter” column of “Connecting Rod Bearing Selection Table”.
5. Select connecting rod bearing of the same grade.

Use Undersize Bearing Usage Guide
When the specified main bearing oil clearance is not obtained with standard size main bearings, use
underside (US) bearing.
When using undersize (US) bearing, measure the main bearing inner diameter with bearing installed, and
grind main journal so that the main bearing oil clearance satisfies the standard.
CAUTION:
In grinding crankshaft main journal to use undersize bear-
ings, keep the fillet R [1.5 mm (0.059 in)].
