What is the primary function of camshaft bearings?

Camshaft bearings support the camshaft within the engine block, allowing it to rotate smoothly. They are critical for maintaining correct valve timing and ensuring proper oil flow to the camshaft.

What does the multi-layer material construction mean for this bearing set?

The multi-layer material construction is designed to handle the high loads and friction experienced by camshaft bearings. This design helps to improve durability and longevity under demanding engine conditions.

Are these bearings a direct replacement for all Mack 6-cylinder engines?

This specific set, part number SH993S, is designed for certain Mack 6-cylinder engine applications. It's important to verify fitment for your particular engine model to ensure compatibility.

About this part

Product Details

This Clevite camshaft bearing set, part number SH993S, is built with a multi-layer material construction. This design helps to manage the high loads and friction that camshaft bearings endure within the engine block. These bearings are crucial for supporting the camshaft, allowing it to rotate smoothly and maintain correct valve timing. If you're rebuilding the top end of a compatible Mack 6-cylinder engine, a fresh set of bearings like these is a fundamental step in ensuring proper oil flow and reducing wear on critical rotating components.

Clevite has a long history in engine bearings, and this set reflects their focus on durability and performance. The precise dimensions and material composition are key to their function, helping to prevent premature wear and potential engine damage. Installing these bearings correctly is essential for the longevity of your engine rebuild, ensuring the camshaft operates within its intended tolerances.
