Mercedes-Benz Engine Connecting Rod Bearing - Kolbenschmidt 6420300360

Product Information

An Engine Connecting Rod Bearing is a precision bearing located between the connecting rod and the crankshaft journal in an internal combustion engine. Its role is to allow smooth rotation of the crankshaft while reducing friction and wear. These bearings are typically made from layers of soft metals (like copper, lead, or aluminum alloys) that can withstand high loads while still being sacrificial (wearing out before the crankshaft does).

• Knocking or tapping noise ("rod knock") – deep metallic knocking from the engine, especially under load or acceleration.
• Low oil pressure – worn bearings create excess clearance, reducing oil pressure.
• Metal shavings in oil – bearing material may flake off and appear in the oil or on the drain plug.
