What is the purpose of main bearings?

Main bearings are crucial engine components that support the crankshaft within the engine block. They allow the crankshaft to rotate smoothly while handling the significant loads generated during combustion.

Why are main bearings replaced during an engine rebuild?

During an engine rebuild, main bearings are typically replaced to ensure correct oil clearance and to prevent wear. New bearings restore the proper gap for lubrication, which is vital for the crankshaft's longevity and the engine's performance.

What is the significance of oil clearance for main bearings?

Oil clearance is the small gap between the crankshaft journal and the bearing surface. This clearance allows a thin film of oil to circulate, lubricating the components and preventing metal-to-metal contact, which is essential for reducing friction and wear.

Product Details

These are individual main bearings from Clevite, part number MB2848AL25. Main bearings are critical components that sit between the crankshaft and the engine block, allowing the crankshaft to rotate smoothly while supporting its weight. When you're rebuilding an engine, especially if you're going beyond a basic refresh, replacing the main bearings is a standard procedure to ensure proper oil clearance and smooth operation.

Clevite is a well-known name in engine bearings, and these are made to meet the demands of engine rebuilding. They are designed to provide the correct oil clearance, which is essential for lubricating the crankshaft and preventing premature wear. Proper oil clearance ensures that the crankshaft has just enough room to spin freely without excessive play, which could lead to noise or damage.

When installing these bearings, it's important to follow the manufacturer's torque specifications and ensure the crankshaft journals are clean and within acceptable tolerances. Always refer to the service manual for your specific engine to confirm the correct installation procedures and oil clearance specifications.
