What does the +0.25mm sizing mean for these bearings?

The +0.25mm sizing indicates that these bearings are intended for use when the crankshaft journals have been machined down by 0.25mm. This is a common practice during engine overhauls to ensure proper clearance and reduce wear on older or rebuilt engines.

What is the construction of these main bearings?

These main bearings are made with a bimetal construction, featuring an aluminum base. This type of material is well-suited for bearing surfaces due to its ability to handle load and heat while maintaining a smooth surface for rotation.

Are these bearings sold individually or as a set?

This product is a main bearing set, meaning it includes all the necessary main bearings required for your Peugeot 404's engine. You receive a complete set to replace all main bearings at once.

Product Details

This is a main bearing set from King Engine Bearings, specifically sized at +0.25mm for your 1961-1970 Peugeot 404. These bearings are crucial for the proper function of your engine's crankshaft, providing a smooth surface for it to rotate within the engine block. They are made with a bimetal construction, featuring an aluminum base, which is a common and effective material for this application.

When you're rebuilding or repairing the bottom end of your Peugeot 404's engine, a fresh set of main bearings is essential. This set is designed to fit your specific vehicle, ensuring that the crankshaft has the correct clearance to operate without excessive wear. The +0.25mm sizing indicates these are intended for use when the original bearing surfaces have been machined down to accommodate this specific undersize, which is a standard practice during engine overhauls to restore proper tolerances.
