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 lower cylinder block, and tighten lower cylinder block bolts with lower cylinder block to the specified torque. Refer to DISASSEMBLY AND ASSEMBLY for the tightening procedure.
CAUTION:
Never rotate crankshaft.
Remove lower cylinder block and bearings, and using the scale on the plastigage bag, measure the plastigage width.

The procedure when the measured value exceeds the limit is the same as that described in the "Method by Calculation".
