What does the +0.75mm sizing mean for these bearings?

The +0.75mm sizing indicates that these bearings are intended for use when the engine's crankshaft journals have been machined down by 0.75mm. This is a common practice during engine rebuilds to ensure proper oil clearance with a worn or resurfaced crankshaft.

What is the advantage of the bimetal aluminum silicon base material?

The bimetal construction combines the strength of aluminum with the wear resistance of silicon. This material is well-suited for the high loads and operating temperatures found in an engine's main bearing system, helping to ensure durability.

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

This product is a main bearing set, which includes the main bearings themselves. It does not typically include other items like crankshaft seals or oil, which may be needed for a complete engine rebuild and should be sourced separately.

Product Details

Built with a bimetal aluminum silicon base, this main bearing set from King Engine Bearings is designed for Ford 155 applications. These bearings are crucial for supporting the crankshaft within the engine block, ensuring it spins smoothly and with minimal friction. This particular set is sized +0.75mm, meaning it's intended for use when the crankshaft journals have been machined to this specific undersize during an engine rebuild.

King Engine Bearings uses a bimetal construction, which combines the strength of aluminum with the wear resistance of silicon. This material choice helps to handle the loads and temperatures found in an engine, contributing to the longevity of your engine's rotating assembly. This set fits a wide range of vehicles, including popular models like the Ford Taurus, Mazda 6, and Mercury Sable, making it a solid option for many engine repair jobs.

When rebuilding an engine, using bearings that are the correct size for the machined crankshaft is essential for proper oil clearance and engine health. This +0.75mm set is a direct replacement for the original main bearings when that specific machining has been performed.
