What does the 0.25 size designation mean for these bearings?

The '0.25' in the part number indicates that these bearings are 0.001 inch undersize. This means they are intended for use when the crankshaft journals have been machined down by 0.001 inches to correct wear or out-of-round conditions.

Are these bearings suitable for a stock 6.7 Power Stroke engine?

These bearings are specifically sized for engines where the crankshaft has been machined to be 0.001 inch undersize. If your crankshaft is still at standard size, you would need a standard size bearing set.

What is the importance of oil clearance with main bearings?

Oil clearance is the small gap between the crankshaft journal and the bearing surface. It's crucial for allowing a thin film of oil to lubricate the surfaces, reduce friction, and dissipate heat. King Engine Bearings designs their bearings to maintain proper oil clearance for reliable engine operation.

About this part

Product Details

This is a set of main bearings from King Engine Bearings, specifically sized at 0.001 inch undersize for Ford 6.7 Power Stroke V8 diesel engines. Main bearings are crucial components that sit between the crankshaft and the engine block, allowing the crankshaft to spin smoothly while supporting its weight and the forces generated during combustion. When rebuilding or repairing your engine, using properly sized and well-built bearings is essential for long-term reliability and performance.

King Engine Bearings is known for its focus on bearing technology, and this set is built with their expertise. The 0.001 inch undersize specification means these bearings are intended for use when the crankshaft journals have been machined down by 0.001 inches to correct wear or out-of-round conditions. This precise sizing ensures the correct oil clearance, which is vital for proper lubrication and preventing premature wear. The construction aims for durability and consistent performance under the demanding conditions of a Power Stroke diesel engine.

When installing these bearings, it's important to ensure the crankshaft journals are clean and within the specified machining tolerance. Proper oiling during assembly and ensuring the correct oil viscosity is used in the engine will help these bearings perform as intended. This set is a solid option for anyone undertaking a rebuild of their 6.7 Power Stroke engine.
