The bearing shells form the replaceable running surface between the connecting rod and crankshaft journal, maintaining the specified oil clearance while carrying combustion and inertia loads.

Common signs of failure:

• Low engine-oil pressure or metallic knocking

• Copper or bearing material found in the lubricating oil

• Excessive big-end oil clearance

• Scored or heat-discoloured crankshaft journal

• Bearing seizure, shell movement or connecting-rod damage
