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

The '+1.0mm' indicates that these bearings are 1.0 millimeter larger in diameter than the original factory size. This is used when the crankshaft has been machined undersize to remove wear or damage, and the new bearings need to match that machined dimension.

What is the construction of these main bearings?

These bearings feature a bimetal construction, meaning they are made from multiple layers of material. They have an aluminum base, which helps with heat dissipation and provides a good bearing surface.

Do these bearings come with installation hardware?

This listing is for the main bearing set only. It does not include any additional installation hardware, such as main cap bolts or oil seals. Always refer to the manufacturer's installation instructions for proper procedure and any required additional parts.

Peugeot 404 1961-1970

Product Details

If you're rebuilding the engine in your 1961-1970 Peugeot 404, a fresh set of main bearings is a critical part of the job. These bearings sit between the crankshaft and the engine block, supporting the rotating assembly and ensuring smooth operation. This set from King Engine Bearings is specifically made for the 404 and is sized 1.0mm over standard, which is common when machining the crankshaft during an engine rebuild to clean up wear.

King uses a bimetal construction with an aluminum base for these bearings. This material choice helps manage heat and provides a good surface for the crankshaft to ride on. Because they are a direct replacement for the original size, they fit right into the prepared block and crankshaft journals, making installation straightforward for a mechanic.
