What does the '0.25' in the part number mean?

The '0.25' indicates that this is a 0.25mm undersize bearing set. This means it is designed to be used when the engine's crankshaft has been machined down by 0.25mm during an engine rebuild.

What engine codes is this bearing set designed for?

This main bearing set is specifically designed for Audi and VW engines that use the CFFA, CAYB, or CAYC engine codes.

Why is using the correct bearing size important?

Using the correct bearing size is critical for maintaining the proper oil clearance within the engine. This clearance ensures an adequate oil film is present between the crankshaft and the bearing, which is essential for lubrication and preventing wear.

About this part

Product Details

King Engine Bearings is well-known for making solid engine bearings. This main bearing set, part number MB5337MC0.25, is built for Audi and VW engines with CFFA, CAYB, or CAYC engine codes. It's a 0.25mm undersize set, meaning it's intended for crankshafts that have been machined down by 0.25mm during an engine rebuild.

Using the correct size bearings is crucial for proper oil clearance. This set ensures that when your crankshaft is machined to the 0.25mm undersize, you have the right bearings to maintain the specified oil film between the crank and the block. This helps protect your engine from wear and ensures it runs smoothly.
