Zusammenfassung:The invention relates to a lash adjuster and a method of making same. A method of manufacturing a lash adjuster body for use in a lash adjuster assembly can include forming a lash adjuster body to an as-formed condition including an outer cylindrical surface and an inner cylindrical surface. The inner cylindrical surface can have a leak down portion and a blind bore. The method can also include imparting a wear resistant surface layer to at least the leak down portion of the inner cylindrical surface with a sub-critical temperature process. The method can also include preserving the leak down portion in the as-formed condition during imparting of the wear resistant surface layer.
