OIL CLEARANCE OF CONNECTING ROD BEARING
Method of Measurement
●Install the connecting rod bearings to the connecting rod and the
cap, and tighten the connecting rod bolts to the specified torque.
Using a inside micrometer measure the inner diameter of con-
necting rod bearing.
(Oil clearance) = (Inner diameter of connecting rod bearing) – (Outer
diameter of crankshaft pin)
●If clearance cannot be adjusted within the standard, grind crank-
shaft pin and use undersized bearing. Refer to EM-81, "
HOW
TO SELECT CONNECTING ROD BEARING" .
Method of Using Plastigage
●Remove oil and dust on the 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 the connecting rod bearings to the connecting rod cap,
and tighten the connecting rod bolts to the specified torque.
CAUTION:
Never 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 bearing) – (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 the oil clearance satisfies the standard. Refer to EM-82,
"HOW TO SELECT MAIN BEARING" .
Method of Using Plastigage
●Remove oil and dust on the crankshaft 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.
●Tighten the main bearing bolts to the specified torque.
CAUTION:
Never 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.”Standard : 0.014 - 0.039 mm (0.0006 - 0.0015 in)
