Method of Using Plastigage

WARNING: This page is about a different variant/trim than selected.

Remove engine oil and dust on crankshaft main journal and the surfaces of each bearing completely.
Cut plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding oil holes.
Install main bearings to cylinder block and lower cylinder block, and tighten lower cylinder block bolts to the specified torque. Refer to [ENGINE UNIT: DISASSEMBLY AND ASSEMBLY ] for the tightening procedure.
CAUTION: Do not rotate crankshaft.
Remove lower cylinder block and bearings, and using scale on plastigage bag, measure the plastigage width.
