What does the +0.50mm sizing mean for these bearings?

The +0.50mm sizing indicates that these bearings are larger than standard. They are designed to be used when the engine's crankshaft journals have been machined down by 0.50mm to remove wear or imperfections. Always confirm your crankshaft journal measurements before ordering.

What is the advantage of a bimetal aluminum base construction?

A bimetal construction with an aluminum base offers a good combination of strength and the ability to conform to the crankshaft surface. This helps ensure consistent oil film and reduces wear on both the bearing and the crankshaft.

Does this main bearing set include everything needed for installation?

This product is a main bearing set, which includes the necessary main bearings for your engine. It does not typically include engine oil, crankshaft seals, or other related installation components, which should be sourced separately.

About this part

Product Details

Built with a bimetal aluminum base, this main bearing set from King Engine Bearings is a solid option for your 1984-1987 Renault Alliance or 1985-1986 Renault Encore. These bearings are a critical part of your engine's rotating assembly, supporting the crankshaft and ensuring it spins smoothly within the engine block. When rebuilding or repairing your engine, using well-made bearings like these helps maintain proper oil clearance and reduce friction.

This set is specifically sized at +0.50mm, meaning it's intended for use when the crankshaft journals have been machined down by 0.50mm to clean up wear or damage. The bimetal construction offers a good balance of strength and conformability, allowing the bearing to adapt to slight imperfections in the crankshaft surface while providing robust support. Proper installation, including ensuring the crankshaft journals are within the specified tolerance for this +0.50mm size and that oil passages are clear, is key to their performance and longevity.
