Abstract
After a connecting rod for an engine is formed, it is broken or fractured at a fracture point to allow the connecting rod to assemble around a portion of a crankshaft. However, before fracturing the connecting rod, the connecting rod is provided with a layer of paint across the eventual fracture point such that when the connecting rod is fractured the paint extends across both sides of the fracture point. Also before fracturing the connecting rod, serial numbers or symbols are etched into the paint on either side of the eventual fracture point. These serial numbers are unique to that connecting rod, and have similar indicia on either side of the connecting rod. The combination of the paint and serial numbers increase the ability of an assembly worker to assure matching parts of an original connecting rod are re-attached during assembly about the crankshaft.
