Method of Using Plastigage

Remove engine oil and dust on 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 connecting rod bearings to connecting rod and cap, and tighten connecting rod bolts to the specified torque. Refer to [ENGINE UNIT: DISASSEMBLY AND ASSEMBLY ] for the tightening procedure.
CAUTION: Do not rotate crankshaft.
Remove connecting rod cap and bearing, and using the scale on the plastigage bag, measure the plastigage width.
