Piston Pin Outer Diameter
Measure the outer diameter of piston pin with micrometer.
Connecting Rod Bushing Oil Clearance
(Connecting rod bushing oil clearance) = (Connecting rod bushing inner diameter) – (Piston pin outer diame-
ter)

If the calculated value exceeds the limit, replace connecting rod assembly and/or piston and piston pin
assembly.

If replacing piston and piston pin assembly, refer to EM-255, "HOW TO SELECT PISTON" .

If replacing connecting rod assembly, refer to EM-269, "CON-
NECTING ROD BEARING OIL CLEARANCE" to select the con-
necting rod bearing.
Factory installed parts grading:

Service parts apply only to grade “0”.

CYLINDER BLOCK DISTORTION

Using scraper, remove gasket on the cylinder block surface, and also remove engine oil, scale, carbon, or
other contamination.
CAUTION:
Be careful not to allow gasket flakes to enter engine oil or engine coolant passages. Standard : 21.989 - 22.001 mm (0.8657 - 0.8662 in)

If out of the standard, measure the main bearing oil clearance. Then use undersize bearing. Refer to EM-
270, "MAIN BEARING OIL CLEARANCE" .
CRANKSHAFT PIN JOURNAL DIAMETER

Measure the outer diameter of crankshaft pin journal with
micrometer.

If out of the standard, measure the connecting rod bearing oil
clearance. Then use undersize bearing. Refer to EM-269,
"CONNECTING ROD BEARING OIL CLEARANCE" .
CRANKSHAFT OUT-OF-ROUND AND TAPER

Measure the dimensions at four different points as shown in the
figure on each main journal and pin journal with micrometer.

Out-of-round is indicated by the difference in the dimensions
between “X” and “Y” at “A” and “B”.

Taper is indicated by the difference in the dimensions 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 the main bearing and/or connecting rod bearing. Refer to EM-270, "
MAIN BEARING OIL CLEAR-
ANCE" and/or EM-269, "CONNECTING ROD BEARING OIL CLEARANCE" .
CRANKSHAFT RUNOUT

Place V-block on precise flat table, and support the journals on
the both end of crankshaft.

Place dial indicator straight up on the No. 3 journal.

While rotating crankshaft, read the movement of the pointer on
dial indicator. (Total indicator reading)

If it exceeds the limit, replace crankshaft. Standard : 63.940 - 63.964 mm (2.5173 - 2.5183 in) dia.
Standard : 51.956 - 51.974 mm (2.0455 - 2.0462 in) dia.

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-249, "
ASSEMBLY" for the tightening procedure.

Measure the inner diameter of connecting rod bearing with
inside micrometer.
(Bearing oil clearance) = (Connecting rod bearing inner diameter) –
(Crankshaft pin journal diameter)

If the calculated value exceeds the limit, select proper connecting rod bearing according to connecting rod
big end diameter and crankshaft pin journal diameter to obtain the specified bearing oil clearance. Refer
to EM-256, "
HOW TO SELECT CONNECTING ROD BEARING" .
Method of Using Plastigage

Remove oil and dust on crankshaft pin journal and the surfaces of each bearing completely.

Cut 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 speci-
fied torque. Refer to EM-249, "
ASSEMBLY" for the tightening procedure.
CAUTION:
Do not rotate crankshaft.

Remove connecting rod bearing cap and bearing, and using
scale on 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”. Standard : 0.020 - 0.045 mm (0.0008 - 0.0018 in)
(actual clearance)
Limit : 0.055 mm (0.0022 in)

MAIN BEARING OIL CLEARANCE
Method by Calculation

Install main bearings to cylinder block and main bearing caps,
and tighten main bearing cap bolts with main bearing to the
specified torque. Refer to EM-249, "
ASSEMBLY" for the tighten-
ing procedure.

Measure the inner diameter of main bearing with bore gauge.
(Bearing clearance) = (Main bearing inner diameter) – (Crankshaft main journal diameter)

If the calculated value exceeds the limit, select proper main bearing according to main bearing inner diam-
eter and crankshaft main journal diameter to obtain the specified bearing oil clearance. Refer to EM-257,
"HOW TO SELECT MAIN BEARING" .
Method of Using Plastigage

Remove oil and dust on crankshaft main journal and the surfaces of each bearing completely.

Cut 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 caps, and tighten main bearing bolts with main
bearing to the specified torque. Refer to EM-249, "
ASSEMBLY" for the tightening procedure.
CAUTION:
Do not rotate crankshaft.

Remove main bearing caps and bearings, and using scale on
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”.
