What does the 1.0mm oversize mean for these bearings?

The '1.0mm oversize' designation means these bearings are designed to fit a crankshaft that has been machined down by 1.0mm. This is typically done to correct for wear or damage on the original crankshaft journals.

What is the advantage of a bimetal aluminum base construction?

A bimetal construction with an aluminum base offers good embeddability and conformability. This helps the bearing adapt to the crankshaft journal, providing consistent oil film support and reducing wear.

Does this main bearing set come with all the necessary hardware for installation?

This listing is for the main bearing set only. It does not include any additional hardware or installation tools. Always refer to the manufacturer's service manual for complete installation requirements.

Product Details

Built with a bimetal aluminum base, this main bearing set from King Engine Bearings is specifically sized at 1.0mm oversize for Peugeot engines. These bearings are crucial for the rotating assembly, providing a smooth, low-friction surface between the crankshaft and the engine block. Ensuring proper clearance and support is key to engine longevity and performance, especially when rebuilding or refreshing an engine.

The bimetal construction, featuring an aluminum base, offers good embeddability and conformability, which helps these bearings adapt to minor imperfections in the crankshaft journal. This design choice contributes to consistent oil film support, reducing wear and heat buildup. Because these are an oversize set, they are intended for use when the crankshaft journals have been machined down by 1.0mm to correct for wear or damage.

When installing this main bearing set, always refer to the manufacturer's service manual for the correct torque specifications and assembly procedures. Proper installation is essential for the bearings to function as intended and to prevent premature engine failure.
