🔌 Function

Carries the connecting rod on the crankshaft journal, holding the oil film that keeps rod and crank apart under firing load.

⚠️ Common Signs of Failure

• Deep knocking from low in the engine, worst under load
• Oil pressure down, particularly hot and at idle
• Metallic glitter in the oil or on the filter element
• Knock rising as the oil thins with temperature
• Bearing shells found scored, wiped or picked up on strip-down

🛠️ Service Notes

• Check the journal for wear and ovality before fitting new shells - new bearings will not save a worn crank
• Renew the rod bolts if they are the single-use type and torque to the figures in the manual for your engine
• Find the reason for the bearing failure - oil supply or contamination - before rebuilding
