CYLINDER BLOCK
• 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 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-93, "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”.

P O Use Undersize Bearing Usage Guide
• When the specified main bearing oil clearance is not obtained with standard size main bearings, use under-
size (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 bearings,
keep the fillet R [1.5 - 1.7 mm (0.059 - 0.067 in)] (A).

CRANKSHAFT END PLAY
• Measure the clearance between thrust bearings and crankshaft
arm when crankshaft is moved fully forward or backward with a dial
indicator (A).
• If the measured value exceeds the limit, replace thrust bearings,
and measure again. If it still exceeds the limit, replace crankshaft
also.
