MAIN BEARING OIL CLEARANCE
Method by Measurement

Install main bearings to cylinder block and bearing cap, and
tighten the bolts to the specified torque. Refer to EM-217,
"ASSEMBLY" . Then, measure the inner diameter of main bear-
ings.
(Bearing clearance) = (Bearing inner diameter) − (Crankshaft
journal outer diameter)

If out of the standard, check main bearing housing inner diame-
ter and crankshaft journal outer diameter, and select appropriate
main bearing to adjust clearance to specifications. Refer to EM-
224, "HOW TO SELECT MAIN BEARING" .
Method of Using Plastigage

Remove contamination such as engine oil and dust completely
from crankshaft journals and each bearing surface.

Cut plastigage slightly shorter than bearing width. Place it in
crankshaft turning direction, avoiding oil holes.

Install main bearings and bearing cap and tighten to the speci-
fied torque. Refer to EM-217, "
ASSEMBLY" for the tightening
procedure.
CAUTION:
Do not rotate crankshaft.

Remove main bearings and bearing caps, and measure plasti-
gage width using scale on plastigage bag.
NOTE:
If out of specification, take same action mentioned in “Method by Measurement”.
CRUSH HEIGHT OF MAIN BEARING

When bearing cap is removed after being tightened to the speci-
fied torque with main bearings installed, the tip end of bearing
must protrude. Refer to EM-217, "
ASSEMBLY" .

If out of the standard, replace main bearings.
CRUSH HEIGHT OF CONNECTING ROD BEARING

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-217,
"ASSEMBLY" .

If out of the standard, replace connecting rod bearings.Standard : 0.039 - 0.066 mm (0.0015 - 0.0026 in)
