PISTON TO CYLINDER BORE CLEARANCE
Cylinder Bore Inner Diameter
 Using a bore gauge (A), measure the cylinder bore for wear, out-
of-round and taper at six different points on each cylinder. (“X” and
“Y” directions at “A”, “B” and “C”) (“Y” is in longitudinal direction of
engine)
NOTE:
When determining cylinder bore grade, measure the cylinder bore
“X” direction at “B” position.
 If the measured value exceeds the limit, or if there are scratches
and/or seizure on the cylinder inner wall, replace cylinder block.
NOTE:
Oversize piston is not provided.
Piston Skirt Diameter
Measure the outer diameter of piston skirt with a micrometer (A).
Piston to Cylinder Bore Clearance
Calculate by piston skirt diameter and cylinder bore inner diameter (direction “X”, position “B”).
(Clearance) = (Cylinder bore inner diameter) – (Piston skirt diameter)
 If it exceeds the limit, replace piston and piston pin assembly and/or cylinder block. Refer to EM-230, "
How
to Select Piston and Bearing".

 If out of the standard, measure the main bearing oil clearance.
Then use undersize bearing. Refer to "MAIN BEARING OIL
CLEARANCE".
CRANKSHAFT PIN JOURNAL DIAMETER
 Measure the outer diameter of crankshaft pin journal with a micrometer.
 If out of the standard, measure the connecting rod bearing oil clearance. Then use undersize bearing. Refer
to "CONNECTING ROD BEARING OIL CLEARANCE".
OUT-OF-ROUND AND TAPER OF CRANKSHAFT
 Measure the dimensions at four different points as shown on each
main journal and pin journal with a micrometer.
 Out-of-round is indicated by the difference in dimensions between
“X” and “Y” at “A” and “B”.
 Taper is indicated by the difference in dimension between “A” and
“B” at “X” and “Y”.
 If the measured value exceeds the limit, correct or replace crankshaft.
 If corrected, measure the bearing oil clearance of the corrected main journal and/or pin journal. Then select
main bearing and/or connecting rod bearing. Refer to "MAIN BEARING OIL CLEARANCE" and/or "CON-
NECTING ROD BEARING OIL CLEARANCE".
CRANKSHAFT RUNOUT
 Place a V-block on a precise flat table to support the journals on
the both end of the crankshaft.

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”.

P O Undersize Bearings Usage Guide
 When the specified connecting rod bearing oil clearance is not obtained with standard size connecting rod
bearings, use undersize (US) bearings.
 When using undersize (US) bearing, measure the connecting rod bearing inner diameter with bearing
installed, and grind the crankshaft pin so that the connecting rod bearing oil clearance satisfies the standard.
CAUTION:
In grinding crankshaft pin to use undersize bearings, keep the
fillet R [1.5 - 1.7 mm (0.059 - 0.067 in)] (A).
