Measure the outer diameter of piston pin with a micrometer (A).
Connecting Rod Bushing Oil Clearance
(Connecting rod bushing oil clearance) = (Connecting rod bushing inner diameter) – (Piston pin outer diame-
ter)
 If the measured value is out of the standard, replace connecting rod assembly and/or piston and piston pin
assembly.
 If replacing piston and piston pin assembly, refer to "PISTON TO PISTON PIN OIL CLEARANCE".
 If replacing connecting rod assembly, refer to "Connecting Rod Bushing Oil Clearance" to select connecting
rod bearing.
CYLINDER BLOCK TOP SURFACE DISTORTION
 Using a scraper, remove gasket on the cylinder block surface, and also remove engine oil, scale, carbon, or
other contamination.
CAUTION:
Be careful not to allow gasket flakes to enter 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 installed, and tighten main bearing cap bolts to the specified
torque. Refer to EM-212, "
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.
NOTE:
Main bearing caps cannot be replaced as a single, because it is machined together with cylinder block. Standard: 19.989 - 19.995 mm (0.7870 - 0.7872 in)

How to Select Piston and BearingINFOID:0000000001337813
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, follow the 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-219, "Inspection After Disassembly".
2. Determine the bore grade by comparing the measurement with the values under the cylinder bore inner
diameter of the “Piston Selection Table”.

HOW TO SELECT CONNECTING ROD BEARING
When New Connecting Rod and Crankshaft are Used
1. Apply connecting rod big end diameter grade stamped (C) on
connecting 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 Crankshaft and Connecting Rod are Reused

HOW TO SELECT PISTON AND BEARING
1. “Main Bearing Selection Table” rows correspond to main bearing
housing grade on rear left side of cylinder block (L).
 If there is a correction stamp mark on cylinder block, use it as
a correct reference.
2. Apply main journal diameter grade stamped on crankshaft front
side to column in the “Main Bearing Selection Table”.
3. Read the symbol at the cross point of selected row and column in the “Main Bearing Selection Table”.
CAUTION:
There are two main bearing selection tables. One is for No. 1, 4 and 5 journals and the other is for
No. 2 and 3 journals. Make certain to use the appropriate table. This is due to differences in the
specified clearances.
4. Apply the symbol obtained to the “Main Bearing Grade Table” to select main bearing.
NOTE:
Service part is available as a set of both upper and lower.
When Cylinder Block and Crankshaft are Reused
1. Measure the dimensions of the cylinder block main bearing housing inner diameter and crankshaft main
journal diameter individually. Refer to EM-219, "
Inspection After Disassembly" and EM-219, "Inspection
After Disassembly".
2. Apply the measured dimension to the “Main Bearing Selection Table”.
3. Read the symbol at the cross point of selected row and column in the “Main Bearing Selection Table”.
CAUTION:
There are two main bearing selection tables. One is for No. 1, 4 and 5 journals and the other is for
No. 2 and 3 journals. Make certain to use the appropriate table. This is due to differences in the
specified clearances.
