Description

The King Engine Bearings crankshaft main bearing set is designed for Mercedes Benz M 272.911 and M 272.920 engines. This set is sized 0.25mm undersize, meaning it is intended for use when the crankshaft journals have been machined to this dimension. Main bearings support the crankshaft within the engine block, allowing for smooth rotation and handling significant forces.

These bearings are crucial components for engine rebuilding or repair, especially when crankshaft wear or damage necessitates machining. Proper oil clearance established by the correct bearing size is essential for lubrication and engine longevity.
