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

The +0.50mm sizing 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 rebuilds to ensure a proper fit and oil clearance.

What is a bimetal bearing construction?

A bimetal bearing uses two different materials bonded together. In this case, it has an aluminum base, which is known for its good bearing properties and compatibility with engine oils.

Are these bearings a direct replacement for the original Peugeot 404 main bearings?

These bearings are a direct fit for the specified Peugeot 404 models, but they are sized at +0.50mm. This means they are intended for an engine where the crankshaft has already been machined to this size during a rebuild.

Product Details

If you're rebuilding the engine in your 1961-1970 Peugeot 404, this Main Bearing Set from King Engine Bearings is a solid option. These bearings are specifically made for the 404 and are sized at +0.50mm, meaning they are intended for use when the crankshaft journals have been machined down by 0.50mm during an engine rebuild.

The bearings themselves are constructed with a bimetal design, utilizing an aluminum base. This construction is common in modern engine bearings because it offers good wear characteristics and compatibility with various oil types. They are designed to handle the loads and stresses within the engine's main bearing journals, helping to ensure smooth rotation of the crankshaft.
