Description
INFOID:0000000009753623
• 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.
Piston
INFOID:0000000009753624
WHEN NEW CYLINDER BLOCK IS USED
• Check the cylinder bore grade on rear left side of cylinder block (L),
and select piston of the same grade.
• If there is a correction stamp mark on the cylinder block, use it as a
correct reference.
WHEN CYLINDER BLOCK IS REUSED

WHEN NEW CONNECTING ROD AND CRANKSHAFT ARE USED
1.
Apply connecting rod big end diameter grade stamped on con-
necting rod side face to the row in the “Connecting Rod Bearing
Selection Table”.
2.
Apply crankshaft pin journal diameter grade stamped on crank-
shaft front side to the column in the “Connecting Rod Bearing
Selection Table”.
3.
Read the symbol at the cross point of selected row and column in the “Connecting Rod Bearing Selection
Table”.
4.
Apply the symbol obtained to the “Connecting Rod Bearing Grade Table” to select connecting rod bearing.
WHEN CONNECTING ROD AND CRANKSHAFT ARE REUSED
1.
Measure the dimensions of the connecting rod big end diameter and crankshaft pin journal diameter indi-
vidually. Refer to
