CRANKSHAFT PIN JOURNAL DIAMETER
Measure outer diameter of crankshaft pin journal with microme-
ter.
If out of the standard, measure the connecting rod bearing oil
clearance. Then use undersize bearing. Refer to EM-142,
"CONNECTING ROD BEARING OIL CLEARANCE" .
CRANKSHAFT OUT-OF-ROUND AND TAPER
Using a micrometer, measure the dimensions at “4” different
points shown in the figure on each journal and pin.
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 the main bearing and/or connecting rod bearing. Refer to EM-143, "
MAIN BEARING OIL CLEAR-
ANCE" and/or EM-142, "CONNECTING ROD BEARING OIL CLEARANCE" .
CRANKSHAFT RUNOUT
Place a V-block on a precise flat table to support journals on the
both end of crankshaft.
Place a dial gauge straight up on No. 3 journal.
While rotating crankshaft, read the movement of the pointer on
the dial gauge. (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 connect-
ing rod bearing cap, and tighten connecting rod bolts to the
specified torque. Using a inside micrometer measure the inner
diameter of connecting rod bearing. Refer to EM-126, "
ASSEM-
BLY" for the tightening procedure.
(Oil clearance) = (Connecting rod bearing inner diameter) – (Crank-
shaft pin diameter)Standard : 51.956 - 51.974 mm (2.0455 - 2.0462 in) dia.

If clearance cannot be adjusted within the standard, grind crankshaft pin and use undersized bearing.
Refer to EM-132, "
HOW TO SELECT 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 bearing width, and place it
in crankshaft axial direction, avoiding oil holes.
Install connecting rod bearings to connecting rod and connect-
ing rod bearing cap, and tighten connecting rod bolts to the
specified torque. Refer to EM-126, "
ASSEMBLY" for the tighten-
ing procedure.
CAUTION:
Never rotate crankshaft.
Remove 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”.
MAIN BEARING OIL CLEARANCE
Method by Calculation
Install main bearings to cylinder block and main bearing cap.
Measure the main bearing inner diameter with bearing cap bolt
tightened with main bearing beam to the specified torque. Refer
to EM-126, "
ASSEMBLY" for the tightening procedure.
(Oil clearance) = (Main bearing inner diameter) – (Crankshaft main
journal diameter)
If the measured value exceeds the limit, select main bearings
referring to the main bearing inner diameter and crankshaft jour-
nal outer diameter, so that the oil clearance satisfies the standard. Refer to EM-133, "
HOW TO SELECT
MAIN BEARING" .
Method of Using Plastigage
Remove engine oil and dust on crankshaft journal and the sur-
faces of each bearing completely.
Cut a plastigage slightly shorter than bearing width, and place it
in crankshaft axial direction, avoiding oil holes.
Install main bearing to cylinder block and main bearing cap, and
tighten main bearing bolts with main bearing beam to the speci-
fied torque. Refer to EM-126, "
ASSEMBLY" for the tightening
procedure.
CAUTION:
Never rotate crankshaft.
Remove 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”.
