Main Bearing Grade Table (All Journals)
Undersize Bearing Usage Guide

When the specified main bearing oil clearance is not obtained with standard size main bearings, use
underside (US) bearing.

When using undersize (US) bearing, measure the main bearing inner diameter with bearing installed, and
grind main journal so that the main bearing oil clearance satisfies the standard.
CAUTION:
In grinding crankshaft main journal to use undersize bear-
ings, keep the fillet R [1.5 - 1.7 mm (0.059 - 0.067 in)].

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-136, "
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 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 connecting rod bearing cap, and tighten connecting
rod bolts to the specified torque. Refer to EM-128, "
ASSEMBLY" for the tightening procedure.
CAUTION:
Do not rotate crankshaft.

Remove connecting rod 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”.
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 beam to
the specified torque. Refer to EM-128, "
ASSEMBLY" for the
tightening procedure.

Measure the inner diameter of main bearing with a bore gauge.
(Oil 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-137,
"HOW TO SELECT MAIN BEARING" .
Method of Using Plastigage

Remove engine oil and dust on 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.

Install main bearing to cylinder block and main bearing cap, and tighten main bearing bolts with main
bearing beam to the specified torque. Refer to EM-128, "
ASSEMBLY" for the tightening procedure.
CAUTION:
Never rotate crankshaft. Standard : 0.034 - 0.059 mm (0.0013 - 0.0023 in)

Remove main bearing caps 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 CRUSH HEIGHT

When main bearing cap is removed after being tightened to the
specified torque with main bearings installed, the tip end of bear-
ing must protrude. Refer to EM-128, "
ASSEMBLY" for the tight-
ening procedure.

If the standard is not met, replace main bearings.
CONNECTING ROD BEARING CRUSH HEIGHT

When connecting rod bearing cap is removed after being tight-
ened to the specified torque with connecting rod bearings
installed, the tip end of bearing must protrude. Refer to EM-128,
"ASSEMBLY" for the tightening procedure.

If the standard is not met, replace connecting rod bearings.
MAIN BEARING CAP BOLT OUTER DIAMETER

Measure the outer diameters (“d1 ”, “d2 ”) at two positions as
shown in the figure.

If reduction appears in “A” range, regard it as “d2 ”.

If it exceeds the limit (large difference in dimensions), replace
main bearing cap bolt with new one.
