Abstract

A method for producing a connecting rod for an internal combustion engine, having a small connecting rod eye for holding a piston pin and having a large connecting rod eye for holding a crank pin, wherein at least one connecting rod eye has at least one geometric deviation from a cylindrical inner contour. It is provided according to the invention that the at least one connecting rod eye is formed by creating a bore with a cylindrical inner contour, and coating the bore with a coating comprising a resin with solid lubricant particles embedded therein. The coating forms the at least one geometric deviation from the cylindrical inner contour of the at least one connecting rod eye.
