What does the '+0.75mm' size mean for these bearings?

The '+0.75mm' designation indicates that these bearings are designed for a crankshaft that has been machined down by 0.75mm. This is a common practice during engine rebuilds to ensure proper fit and oil clearance when the original crankshaft journals have wear or damage.

What is the bimetal construction with an aluminum base?

Bimetal bearings typically consist of a steel backing for strength and a bearing surface material, in this case, aluminum-based. This construction is chosen for its good load-carrying capabilities and ability to manage heat effectively within the engine.

Are these bearings sold individually or as a set?

This product is a connecting rod bearing set, meaning it includes all the necessary bearings for the connecting rods on your engine.

Product Details

These connecting rod bearings are built with a bimetal construction, featuring an aluminum base. This design is crucial for the demanding environment inside your engine, helping to manage heat and reduce friction between the crankshaft and connecting rod. They are specifically sized at +0.75mm, meaning they are intended for engines where the crankshaft journals have been machined down by 0.75mm during a rebuild or repair process.

King Engine Bearings is known for making well-built engine components, and this set is no different. The bimetal material offers good load-carrying capacity and wear resistance, which is exactly what you need for reliable engine operation. Installing bearings of the correct size is critical for maintaining proper oil clearance, ensuring the crankshaft spins smoothly without excessive play.

If you're rebuilding the engine in your Renault Alliance, Encore, LeCar, or R10, and the crankshaft journals have been machined to a +0.75mm undersize, this set from King is a solid option to get your engine back in reliable running condition.
