EM-98 < DISASSEMBLY AND ASSEMBLY > ENGINE UNIT • Remove oil and dust on the crankshaft pin and surfaces of each bearing completely. • Cut a plastigage slightly shorter than the bearing width, and place it in the crankshaft axial direction, avoiding oil holes. • Install the connecting rod bearings to the connecting rod and con- necting rod bearing cap, and tighten the connecting rod bolts to the specified torque. CAUTION: Do not rotate crankshaft with plastigage installed. • Remove the connecting rod bearing cap and bearings. Measure the plastigage width using the scale on the plastigage bag. NOTE: The procedure when the measured value exceeds the repair limit is the same as that described in “Method of Measurement”. MAIN BEARING OIL CLEARANCE Method of Measurement • Install the main bearings to the cylinder block and main bearing cap. Measure the main bearing inside diameter with the bearing cap bolts tightened to the specified torque. Refer to . (Oil clearance) = (Inside diameter of main bearing) – (Crankshaft journal diameter) • If measured value exceeds the repair limit, select main bearings referring to the main bearing inside diame- ter and crankshaft journal diameter, so that the oil clearance satisfies the standard. Refer to Method of Using Plastigage • Remove oil and dust on the crankshaft journal and 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 the main bearings to the cylinder block and main bearing cap, and tighten the main bearing bolts to the specified torque. CAUTION: Do not rotate crankshaft with plastigage installed. • Remove bearing cap and bearings. Measure plastigage width using the scale on the plastigage bag. NOTE: The procedure when the measured value exceeds the repair limit is the same as that described in “Method of Measurement”.
