What does the +0.25mm size mean for these bearings?

The +0.25mm (or .002 inches) designation indicates that these bearings are slightly larger than standard. They are intended for use when the engine's crankshaft connecting rod journals have been machined down by 0.002 inches during an engine rebuild. This ensures the correct oil clearance is maintained.

What is the construction of these bearings?

These bearings feature a bimetal construction with an aluminum silicon base. This type of material is chosen for its good load-carrying capacity and wear resistance, making it suitable for the high-stress environment of an engine's connecting rod journals.

Are these bearings a direct replacement for all Ford 415 engines?

This set is specifically sized at +0.25mm and is an optional replacement for the CR1039SI when the housing bore requires that specific oversize. It's crucial to confirm that your crankshaft journals have been machined to this exact size and that this is the correct bearing for your engine's specifications.

Product Details

When you're rebuilding the bottom end of your Ford 415 engine, getting the connecting rod bearings right is crucial for smooth operation and longevity. This set from King Engine Bearings is designed to fit a range of Ford trucks, including models like the E-350 Super Duty and F-250 Super Duty, ensuring you have the right parts for your project.

These bearings are constructed with a bimetal design, featuring an aluminum silicon base. This material choice helps manage heat and wear effectively. This specific set is sized at +0.25mm (or .002 inches oversize on the housing bore), which is important when the crankshaft journals have been machined to match. Using the correct oversize bearing ensures proper oil clearance, which is vital for lubricating the connecting rod and crankshaft connection.

This set is an optional replacement for the CR1039SI when the housing bore requires the +.002 inch adjustment. Make sure to verify your crankshaft journal dimensions and required bearing size before ordering to ensure a perfect fit for your engine rebuild.
