What does the '1.0' size mean for these bearings?

The '1.0' designation indicates that these bearings are 0.001 inches undersize. This means they are intended for use when the crankshaft journals have been machined down by 0.001 inches from their original factory specifications.

Are these bearings sold individually or as a set?

This product is a set of crankshaft main bearings. It includes all the main bearings required for servicing the crankshaft in the specified Mercedes Benz engines.

What is the primary function of main bearings in an engine?

Main bearings support the crankshaft within the engine block. They create a low-friction surface that allows the crankshaft to rotate smoothly while handling the significant forces generated during engine operation.

About this part

Product Details

This is a King Engine Bearings crankshaft main bearing set, specifically for Mercedes Benz M 272.911 and M 272.920 engines. This set includes the main bearings needed to rebuild or service the crankshaft in these specific Mercedes engines. Bearings are crucial for smooth engine operation, as they create a low-friction surface between the crankshaft and the engine block, allowing the crankshaft to rotate freely while supporting its weight and the forces from combustion.

This particular set is sized 1.0, meaning it's designed for crankshaft journals that have been machined down by 0.001 inches from their original size. Using the correct bearing size is essential for maintaining proper oil clearance, which is critical for lubrication and preventing premature wear. King Engine Bearings are known for their well-built construction, aiming to provide reliable performance for your engine rebuild.
