Abstract
A powder metal component (34) has an outer diameter that is inserted in a bore of another component (18) during assembly with an interference fit between the two components. Ribs (30) are formed on the outer diameter of the component (34) during compaction and sintering of the component. The ribs (30) have a surface that has been compressed to a greater density than a surface (31) of the outer diameter between the ribs to produce a major diameter and effective roundness defined by high points of the ribs.
