What does 'undersize 0.020 inch' mean for these bearings?

This means the bearings are manufactured to be slightly smaller than standard size. They are intended for use when the engine's crankshaft has been machined down by 0.020 inches to correct wear or damage.

Why is proper oil clearance important with main bearings?

Proper oil clearance allows oil to flow between the bearing and the crankshaft, providing lubrication and cooling. This prevents metal-on-metal contact, reducing wear and extending the life of both components.

Does this set include all the main bearings needed for an engine rebuild?

Typically, a main bearing set includes all the necessary main bearings for a complete engine. However, it is always best to consult the product packaging or manufacturer's specifications to confirm the exact contents for this specific set.

Product Details

These Clevite main bearings are 0.020 inch undersize, meaning they are designed to be used with a crankshaft that has been machined down by that amount. Main bearings are critical components that sit between the crankshaft and the engine block, providing a smooth, low-friction surface for the crankshaft to rotate on. When rebuilding or repairing an engine, especially after machining the crankshaft, using the correct size bearings is essential for proper oil clearance and engine longevity.

Clevite is a well-known name in engine components, and this set is built to meet the demands of engine rebuilding. The precise sizing ensures that when installed on a machined crankshaft, they will provide the correct oil clearance, which is vital for lubricating the rotating assembly and dissipating heat. Proper oil clearance allows oil to flow freely, preventing metal-on-metal contact and reducing wear on both the bearings and the crankshaft.

When you're working on an engine rebuild and have had your crankshaft turned, this set of Clevite main bearings is a solid option to ensure you're getting the correct fit and reliable performance. Always refer to your engine's specific service manual for detailed installation instructions and recommended oil clearances.
