What causes connecting rod bearing failure?

DAMAGING ACTION A bent or twisted connecting rod results in misalignment of the bore, causing the bearing to be cocked so the bearing edge makes metal-to- metal contact with the journal which can cause excessive wear on the bearing surface.

Can you replace one connecting rod bearing?

The rod bearing must either be replaced along with fixing associated parts (you don’t usually replace just one rod bearing as the entire engine would need rebuilt at that point), or the engine will need to be replaced.

What causes rod bearing failure?

Most of engine bearing failures are caused by one of the two factors: – Mixed lubrication with direct metal-to-metal contact between the bearing and crankshaft surfaces; – Fatigue of the bearing material. Mixed lubrication is one of the main causes of engine bearing failures.
