ENGINE UNIT
Do not rotate crankshaft.
• Remove lower cylinder block 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”.
CRUSH HEIGHT OF MAIN BEARING
• When lower cylinder block is removed after being tightened to the
specified torque with main bearings installed, the tip end of bearing
must protrude. Refer to EM-103, "Disassembly and Assembly"
for
the tightening procedure.
• If the standard is not met, replace main bearings.
CRUSH HEIGHT OF CONNECTING ROD BEARING
• When connecting rod bearing cap is removed after being tightened
to the specified torque with connecting rod bearings installed, the
tip end of bearing must protrude. Refer to EM-103, "Disassembly
and Assembly" for the tightening procedure.
• If the standard is not met, replace connecting rod bearings.
LOWER CYLINDER BLOCK BOLT OUTER DIAMETER
• Measure the outer diameters [(d1), (d2)] at two positions as shown.
• If reduction appears in (A) range, regard it as (d
2).
• If it exceeds the limit (large difference in dimensions), replace
lower cylinder block bolt with new one.
