What does the +0.50mm size mean for these bearings?

The +0.50mm designation indicates that these bearings are intended for use when the crankshaft journals have been machined down by 0.50mm. This is a common practice during engine rebuilding to remove wear or minor damage from the original journals.

What is the construction of these main bearings?

These bearings are made with a bimetal construction, which means they have multiple layers of material. The base layer is aluminum, providing a solid foundation, while other layers form the bearing surface that contacts the crankshaft.

What is the function of main bearings in an engine?

Main bearings are crucial components that support the crankshaft within the engine block. They allow the crankshaft to rotate smoothly while withstanding the significant forces from the pistons and combustion process, helping to maintain proper oil pressure.

Product Details

If you're rebuilding the engine in your 1961-1970 Peugeot 404, this Main Bearing Set from King Engine Bearings is what you'll need. These bearings sit between the crankshaft and the engine block, supporting the rotating crankshaft and handling the immense forces generated during combustion. This set is specifically sized at +0.50mm, meaning it's intended for use when the crankshaft journals have been machined down by 0.50mm to clean up wear or damage.

King Engine Bearings uses a bimetal construction with an aluminum base for these bearings. This material choice helps manage heat and provides a solid foundation for the bearing surface. Proper main bearing installation is critical for oil pressure and crankshaft longevity, so ensure your crankshaft journals are prepped to the correct +0.50mm size before installation.
