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".

CYLINDER BLOCK
Method of Using Plastigage
• Remove oil and dust on the crankshaft journal 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.
• Tighten the main bearing bolts to the specified torque. CAUTION:
Do not rotate the crankshaft.
• Remove the bearing 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".
CRUSH HEIGHT OF MAIN BEARING
• When the bearing cap is removed after being tightened to the specified torque with main bearings installed, the tip end of bearing
must protrude.
• If the standard is not met, replace main bearings.
OUTER DIAMETER OF LOWER CYLINDER BLOCK BOLT
• Perform only with M10 (0.39 in) bolts.
• Measure outer diameters (d1, d2) at two positions as shown.
• Measure d2 at a point within area (A) as shown.
• When the value of d1- d2 exceeds the limit (a large difference in dimensions), replace the bolt with a new one.
OUTER DIAMETER OF CONNECTING ROD BOLT
• Measure outer diameter (d) at position as shown.
• When (d) exceeds the limit (when it becomes thinner), replace the
bolt with a new one.

Standard : There must be crush height.

How to Select Piston and BearingINFOID:0000000009460512
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
crankshaft Main bearing
Main bearing grade (bearing

der block bearing housing

Connecting rod bearing grade
(bearing thickness) Combining service grades for

HOW TO SELECT PISTON AND BEARING
When a Cylinder Block is Reused:
1. Measure the cylinder block bore inner diameter.
2. Determine the bore grade by comparing the measur ement with the values under the cylinder bore inner
diameter of the "Piston Selection Tabl e". Select the piston of the same grade.
Piston Selection Table
• For the piston selection table, refer to EM-111, "Standard and Limit".
NOTE:
• The piston is available together with piston pin as an assembly.
• The piston pin (piston pin bore) grade is provided only for the parts installed at the plant. For service parts, no grades can be selected. Only 0 grade is available.
HOW TO SELECT A CONNECTING ROD BEARING
When New Connecting Rod and Crankshaft are Used:
1. Apply big end inside diameter grade stamped on connecting rod side face to the row in the "Connecting Rod Bearing Selection
Table".
2. Apply pin diameter grade (B) stamped on crankshaft front side to the column in the "Connecting Rod Bearing Selection Table".
• Journal diameter grade (A)
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 connecting rod bearing grade table to select.
When Crankshaft and Connecting Rod are Reused:
1. Measure dimensions of the big end inner diameter of connecting rod and outer diameter of crankshaft pin
individually.
2. Apply the dimension measured to the "Connec ting Rod Bearing Selection Table" below.
(A) : Oil splash
(B) : Small end diameter grade
(C) : Reference code
(D) : Bearing stopper groove
(E) : Reference code
(F) : Cylinder No.
(G) : Big end diameter grade

Undersize Bearing Usage Guide
• When the specified oil clearance is not obtained with standard size connecting rod bearing, use undersize
(US) bearing.
• When using undersize bearing, measure the bearing inner diameter with bearing installed, and grind the
crankshaft pin so that the oil clearance satisfies the standard.

HOW TO SELECT PISTON AND BEARING
1. "Main Bearing Selection Table" rows correspond to bearing
housing grade on rear left side of cylinder block.
• If there is a corrected stamp ma rk on the cylinder block, use it
as a correct reference.
2. Apply journal diameter grade (A) stamped on crankshaft front side to column in "Main Bearing Selection Table".
3. Find value at crossing of row and column in "Main Bearing Selection Table". CAUTION:
• There are two main bearing selecti on tables. One is for odd-numbered journals (1, 3, and 5) and
the other is for even-numbered journals (2 and 4) . Make certain to use the appropriate table. This
is due to differences in the specified clearances.
4. Apply the symbol obtained to "Main Bearing Grade Table" to select. NOTE:
• Service parts are available as a set of both upper and lower.
When Cylinder Block and Crankshaft are Reused:
1. Measure inner diameter of cylinder block main bear ing housing and outer diameter of crankshaft journal.
2. Apply measurement in above step 1 to the "Main Bearing Selection Table".
3. Follow steps 3 and 4 in "When New Cylinder Block and Crankshaft are Used".
