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

The +0.75mm designation means these bearings are slightly larger than standard size. They are intended for use when the engine's crankshaft journals have been machined down by 0.75mm to correct for wear or damage. This ensures the correct oil clearance is maintained.

What is the advantage of a bimetal aluminum base construction?

A bimetal construction with an aluminum base offers a good balance of strength, wear resistance, and conformability. This design helps the bearing to properly seat against the crankshaft and withstand the loads placed upon it during engine operation.

Do these bearings come with installation instructions?

While these bearings are designed as a direct replacement, it is always recommended to refer to the vehicle manufacturer's service manual or King Engine Bearings' installation guidelines for proper procedure and torque specifications.

About this part

Product Details

This main bearing set from King Engine Bearings features a bimetal construction with an aluminum base, a solid choice for rebuilding or repairing the bottom end of many Audi and Volkswagen engines. These bearings are specifically sized at 0.75mm oversize, which is crucial when the crankshaft journals have been machined down to correct for wear or damage. Using the correct oversize bearing ensures proper oil clearance, which is vital for engine longevity and performance.

King Engine Bearings is a well-known name in engine components, and this set is built to meet the demands of a wide range of Audi and VW models, including popular vehicles like the Volkswagen Golf and Jetta, as well as older Audi 4000 models. The bimetal design offers good wear resistance and load-carrying capacity, making it a reliable option for keeping your engine running smoothly.

When you're rebuilding an engine, getting the bearing clearances right is key. This set, being 0.75mm oversize, is designed to work with a crankshaft that has been turned down by that amount. Always ensure your crankshaft journals are properly measured and machined to the correct size before installing these bearings to achieve the intended oil clearance.
