How to Select Piston and BearingINFOID:0000000005398147
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 dimens ion 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, follow the applicable procedures.
HOW TO SELECT PISTON
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
1. Measure the cylinder bore inner diameter. Refer to EM-212, "Inspection After Disassembly".
2. Determine the bore grade by comparing the measur ement with the values under the cylinder bore inner
diameter of the “Piston Selection Table”.

Measure the outer diameter of piston pin with a micrometer (A).
Connecting Rod Bushing Oil Clearance
(Connecting rod bushing oil clearance) = (Connecting rod bus
hing inner diameter) – (Piston pin outer diame-
ter)
• If the measured value is out of the standard, repl ace connecting rod assembly and/or piston and piston pin
assembly.
• If replacing piston and piston pin assembly, follow the "PISTON TO PISTON PIN OIL CLEARANCE" proce-
dure.
• If replacing connecting rod assembly, follow the "Connecting Rod Bushing Oil Clearance" procedure to select connecting rod bearing.
CYLINDER BLOCK TOP SURFACE DISTORTION
• Using a scraper, remove gasket on the cylinder block su rface, and also remove engine oil, scale, carbon, or
other contamination.
CAUTION:
Be careful not to allow gasket flakes to en ter engine oil or engine coolant passages.
• Measure the distortion on the cylinder block upper face at some
different points in six directions with a straight edge (A) and feeler
gauge (B).
• If it exceeds the limit, replace cylinder block.
MAIN BEARING HOUSING INNER DIAMETER
• Install main bearing cap without main bearings install ed, and tighten main bearing cap bolts to the specified
torque. Refer to EM-196, "
Disassembly and Assembly" for the tightening procedure.
• Measure the inner diameter of main bearing housing with a bore gauge.
• Measure the position shown [5 mm (0.20 in)] backward from main bearing housing front side in the 2 directions as shown. The
smaller one is the measured value.
• If out of the standard, replace cylinder block and main bearing caps assembly.
