What does the +0.75mm size mean for these main 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 rebuilding to address wear or imperfections on the crankshaft journals.

What are these main bearings made of?

These main bearings are constructed using a bimetal design, which includes an aluminum base. This material choice helps in managing heat and wear within the engine's critical crankshaft support system.

Do I need to machine my crankshaft to use these bearings?

Yes, if your crankshaft journals show wear or damage, they will likely need to be machined down to the specific undersize that matches these +0.75mm bearings. It is recommended to consult with a professional engine builder or machinist to confirm the correct procedure and measurements for your specific engine.

Product Details

If you're rebuilding the engine in your 1983-1987 Renault Alliance, Encore, or LeCar, this Main Bearing Set from King Engine Bearings is a critical component. These bearings sit in the engine block and support the crankshaft, allowing it to spin smoothly. This specific set is sized +0.75mm, meaning it's intended for use when the crankshaft journals have been machined down by 0.75mm to clean up wear or damage.

King Engine Bearings uses a bimetal construction with an aluminum base for these main bearings.

Proper main bearing clearance is essential for oil pressure and the overall health of your engine, so using a well-built replacement like this set is important for a successful rebuild.
