The CONNECTING ROD BEARING SET with the part number HCB161-2630 and the designation “- .010” indicates an undersized bearing set for the connecting rod bearings in an engine. The “- .010” notation signifies that these bearings are undersized by 0.010 inches compared to the standard size. Undersized bearings like these are used when engine components, such as the connecting rods or crankshaft, have been machined or worn, and a smaller bearing is required to achieve the proper clearances. Connecting rod bearings are critical engine components that support and allow the rotation of the engine’s crankshaft, specifically at the connecting rod’s big end. They help distribute the load and forces exerted on the crankshaft, reducing friction and enabling smooth rotation. The undersized designation ensures a precise fit in the engine, allowing for correct clearances and optimal performance. The part number HCB161-2630 serves as a unique identifier, allowing individuals and mechanics to identify and order the correct connecting rod bearing set for a specific engine or vehicle model, ensuring a proper fit and optimal functioning within the engine’s connecting rod assembly.
