CYLINDER BLOCK

Cylinder Bore Inner Diameter

• Using a bore gauge, 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
the engine)

NOTE:
When determining cylinder bore grade, measure cylinder bore 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:
There is no service setting for oversized piston.

Piston Skirt Diameter

Measure the outer diameter of piston skirt with a micrometer.

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.

CRANKSHAFT MAIN JOURNAL DIAMETER

• Measure the outer diameter of crankshaft main journals with a

micrometer (A).

• If out of the standard, measure the main bearing oil clearance.

Then use undersize bearing.

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. 

OUT-OF-ROUND AND TAPER OF CRANKSHAFT

• Measure the dimensions at four different points as shown in the

figure 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. 

CRANKSHAFT RUNOUT 

• Place a V-block on a precise flat table to support the journals on

the both end of crankshaft.

• Place a dial indicator (A) straight up on the No. 3 journal. 
• While rotating crankshaft, read the movement of the pointer on the

dial indicator. (Total indicator reading)

• If it exceeds the limit, replace crankshaft.

CONNECTING ROD BEARING OIL CLEARANCE

Method by Calculation

• Install connecting rod bearings to connecting rod and cap, and tighten connecting rod bolts to the specified

torque. Refer to 

EM-101, "Disassembly and Assembly"

. 

• Measure the inner diameter of connecting rod bearing with an

inside micrometer.
(Bearing oil clearance) = (Connecting rod bearing inner diameter)
– (Crankshaft pin journal diameter)

• If the clearance exceeds the limit, select proper connecting rod

bearing according to connecting rod big end diameter and crank-
shaft pin journal diameter to obtain the specified bearing oil clear-
ance. Refer to 

EM-117, "Connecting Rod Bearing"

.

Method of Using Plastigage

• Remove engine oil and dust on crankshaft pin and the surfaces of each bearing completely. 
• Cut a plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding oil

holes.

• Install connecting rod bearings to connecting rod and cap, and tighten connecting rod bolts to the specified

torque. Refer to 

EM-101, "Disassembly and Assembly"

.

CYLINDER BLOCK

Never rotate crankshaft.

• Remove connecting rod cap and bearing, 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”.

MAIN BEARING OIL CLEARANCE

Method by Calculation

• Install main bearings to cylinder block and main bearing cap, and tighten main bearing cap bolts to the spec-

ified torque. Refer to 

EM-101, "Disassembly and Assembly"

. 

• Measure the inner diameter of main bearing with a bore gauge.
(Bearing oil clearance) = (Main bearing inner diameter) – (Crank-
shaft main journal diameter)

• If the clearance exceeds the limit, select proper main bearing

according to main bearing inner diameter and crankshaft main
journal diameter to obtain the specified bearing oil clearance.
Refer to 

EM-119, "Main Bearing"

.

Method of Using Plastigage

• Remove engine oil and dust on crankshaft main journal and the surfaces of each bearing completely. 
• Cut a plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding oil

holes.

• Install main bearings to cylinder block and main bearing cap, and tighten main bearing cap bolts to the spec-

ified torque. Refer to 

EM-101, "Disassembly and Assembly"

. 

CAUTION:

Never rotate crankshaft.

• Remove main 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”.
