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

The +0.75mm sizing means these bearings are designed to be used when the crankshaft journals have been machined down by 0.75mm. This is a common practice during engine rebuilding to clean up wear or damage, and the undersize bearing restores the correct clearance between the crankshaft and the main bearing housing.

What is a bimetal aluminum base construction?

A bimetal aluminum base construction uses multiple layers of metal. Typically, a strong aluminum alloy forms the base, providing good heat dissipation and conformability, while a bearing overlay provides wear resistance. This combination is well-suited for the demanding environment of an engine's main bearing system.

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 a complete engine rebuild or replacement of the main bearings for the specified engine.

About this part

Product Details

This is a King Engine Bearings Main Bearing Set, specifically sized at +0.75mm for Mitsubishi 6G74 engines. You get the main bearings needed to rebuild or replace the core rotating assembly in engines like those found in many Mitsubishi Diamante, Endeavor, and Galant models, as well as certain Hyundai and Kia vehicles. These bearings are constructed with a bimetal aluminum base, a common and reliable material for engine bearings that helps manage heat and wear.

When you're rebuilding an engine, the main bearings are critical for supporting the crankshaft and ensuring it spins smoothly. This set is built with a bimetal construction, meaning it uses layers of different metals to create a strong yet compliant surface that can handle the pressures and temperatures inside the engine. The +0.75mm sizing indicates these are intended for use when the crankshaft journals have been machined down by 0.75mm to clean up wear or damage, requiring a corresponding undersize bearing to restore proper clearances.
