What does the .020 inch undersize mean for this bearing set?

The .020 inch undersize indicates that these bearings are designed for a crankshaft that has been machined down by 0.020 inches from its original size. This is common during engine rebuilding to correct wear or achieve specific clearances.

What is the construction of these main bearings?

These bearings feature a tri-metal design with a high-performance overlay. This construction is intended to help dissipate heat effectively and resist wear during engine operation.

Are these bearings suitable for all engine rebuilds?

These specific bearings are for engines that require a .020 inch undersize on the main crankshaft journals. Always verify your engine's specifications and the required bearing size before purchasing.

Product Details

This main bearing set from King Engine Bearings is built with a .020 inch undersize, making it suitable for engine rebuilding projects where crankshaft journals have been machined to this specification. These bearings are a key component in your engine's rotating assembly, supporting the crankshaft and allowing it to spin smoothly within the engine block. Proper bearing clearance is critical for oil flow and preventing metal-on-metal contact, which can lead to catastrophic engine failure.

King Engine Bearings uses a unique tri-metal design with a high-performance overlay. This construction helps to dissipate heat effectively and resist wear, even under demanding operating conditions. The .020 inch undersize is important because it means these bearings are intended for use on a crankshaft that has been ground down by 0.020 inches from its original size to correct imperfections or to achieve a specific clearance. Ensuring you have the correct undersize is crucial for proper engine assembly and longevity.

When rebuilding an engine, it's important to ensure all components are clean and properly lubricated before installation. Always refer to your vehicle's service manual for specific installation procedures and torque specifications to ensure these bearings perform as intended.
