What does the +0.75mm sizing mean for this bearing set?

The +0.75mm designation indicates that these bearings are undersized by 0.75mm. They are intended for use when the crankshaft journals have been machined down by that amount during an engine rebuild to correct wear or damage.

What is a bimetal bearing?

A bimetal bearing, like this set, uses two different materials bonded together. In this case, it has an aluminum base, which is known for its good wear characteristics and ability to conform to the crankshaft surface.

Does this set include all the main bearings needed for the engine?

This is a main bearing set, which typically includes all the bearings that support the crankshaft within the engine block. Always refer to your vehicle's service manual for a complete list of parts required for your specific engine rebuild.

About this part

Product Details

King Engine Bearings is known for making solid engine bearings, and this main bearing set for your Renault R9 or R11 is no different. If you're rebuilding the engine in your 1984-1987 Renault Alliance, these bearings are a key component to get your crankshaft spinning smoothly again. They are a bimetal type, meaning they have an aluminum base, which is a common and effective material for this application.

This particular set is sized at +0.75mm, meaning it's designed to be used when the crankshaft journals have been machined down by 0.75mm. This is a standard procedure when dealing with worn or damaged crankshafts during an engine rebuild. Using the correct size bearing ensures proper oil clearance, which is critical for engine longevity and performance. King uses a bimetal construction, which offers good wear resistance and conformability to the crankshaft.
