• Calculate by outer diameter of piston skirt and i
nner diameter of cylinder (direction X, position B).
(Clearance) = (Inner diameter of cylinde r) – (Outer diameter of piston skirt).
• If it exceeds the limit, replace piston/piston pin assembly.
Reboring Cylinder Bore
1. Cylinder bore size is determined by adding pi ston-to-bore clearance to piston diameter (A).
2. Install lower cylinder block, and tighten to the specif ied torque. Otherwise, cylinder bores may be distorted
in final assembly.
3. Cut cylinder bores.
• When any cylinder needs boring, all ot her cylinders must also be bored.
• Do not cut too much out of cylinder bore at a time . Cut only 0.05 mm (0.0020 in) or so in diameter at
a time.
4. Hone cylinders to obtain specified piston-to-bore clearance.
5. Measure finished cylinder bore for out-of-round and taper.
• Measurement should be done af ter cylinder bore cools down.
OUTER DIAMETER OF CRANKSHAFT JOURNAL
• Measure outer diameter of crankshaft journals using suitable tool
(A).
OUTER DIAMETER OF CRANKSHAFT PIN
• Measure outer diameter of crankshaft pin using a suitable tool.
OUT-OF-ROUND AND TAPER OF CRANKSHAFT
• Measure the dimensions at four different points as shown on eachjournal and pin using 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). Standard : 0.010 - 0.030 mm (0.0004 - 0.0012 in)
Limit : 0.08 mm (0.0031 in)

CRANKSHAFT RUNOUT
• Place a V-block on a precise flat table to support the journals on
both ends of the crankshaft.
• Place a dial gauge (A) straight up on the No. 3 journal.
• While rotating the crankshaft, read the movement of the pointer on the dial gauge (A), the total indicator runout reading.
OIL CLEARANCE OF CONNECTING ROD BEARING
Method of Measurement
• Install the connecting rod bearings (2) to the connecting rod (3)
and the cap (1), and tighten the c onnecting rod bolts to the speci-
fied torque. Using a inside micrometer measure the inner diameter
of connecting rod bearing (B).
(Oil clearance) = (Inner diameter of connecting rod bearing) –
(Outer diameter of crankshaft pin)
• If clearance cannot be adjusted within the standard, grind crankshaft pin and use undersized bearing. Refer
to EM-105, "How to Select Piston and Bearing"
.
Method of Using Plastigage
• Remove oil and dust on the crankshaft pin and the surfaces of
each bearing completely.
• Cut the Plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding oil holes.
• Install the connecting rod bearings to the connecting rod cap, and tighten the connecting rod bolts to the specified torque.
CAUTION:
Do not rotate the crankshaft.
• Remove the connecting rod cap and bearings, and using the scale on the Plastigage bag, measure the Plastigage width.
NOTE:
The procedure when the measured value exceeds the limit is
same as that described in the method by calculation.
OIL CLEARANCE OF MAIN BEARING
Method of Measurement
• Install the main bearings to the cylinder block and bearing cap. Measure the main bearing inner diameter with the bearing cap bolt tightened to the specified torque.
(Oil clearance) = (Inner diameter of main beari ng) – (Outer diameter of crankshaft journal)
• If the measured value exceeds the limit, select main bearings referring to the main bearing inner diameter
and crankshaft journal outer diameter, so that t he oil clearance satisfies the standard. Refer to EM-105,
"How to Select Piston and Bearing".

DESCRIPTION
*For the service parts, the grade for fitting c
annot be selected between a piston pin and a connecting rod.
(Only 0 grade is available.) The information at the sh ipment from the plant is described as a reference.
• 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 A PISTON
When New Cylinder Block is Used:
• Check the cylinder bore grade on rear left side of cylinder block, and select a piston of the same grade.
• If there is a corrected stamp mark on the cylinder block, use it as a correct reference.
Selection points Selection parts Selection items Selection methods
Between cylinder block to
