What is the main purpose of main bearings in an engine?

Main bearings support the crankshaft within the engine block. They allow the crankshaft to rotate smoothly while maintaining the correct oil clearance, which is crucial for lubrication and oil pressure.

What does 'STD' size mean for these bearings?

STD stands for standard size. This means the bearings are manufactured to the original equipment specifications and are intended for use with a crankshaft that has not been machined undersize.

Are any special tools or procedures needed for installation?

Installation of main bearings requires careful attention to cleanliness and proper torque specifications. Always refer to the manufacturer's official service manual for detailed installation instructions and recommended procedures.

About this part

Product Details

When you're rebuilding the bottom end of your Audi or VW 1.8L or 2.0L engine, getting the main bearings right is critical for proper crankshaft support and oil pressure. King Engine Bearings offers this standard-size main bearing set, designed to meet the demands of a fresh engine build.

These bearings are built with a focus on durability and consistent performance. The standard size ensures a precise fit for your crankshaft journals, which is essential for maintaining the correct oil clearance. Proper oil clearance allows the engine oil to flow correctly, lubricating and cooling the crankshaft as it spins. King uses well-built materials and construction methods to ensure these bearings can handle the stresses of regular operation.

This set includes all the main bearings needed for your engine. Make sure to follow the manufacturer's installation instructions carefully to ensure proper seating and oiling for long-lasting performance.
