Abstract
A sintered powder metal part and a related method of making the part are disclosed. The sintered powder metal part, which is formed from a compacted and sintered powder metal, includes a hub having a radially-outwardly facing surface and a radially-inward facing surface. A toothed profile is formed in one of the radially-outwardly and radially-inward facing surfaces of the hub. One or more grooves are machined into the other of the surfaces of the hub such that the toothed profile and the one or more grooves are on oppositely-facing radial sides of the hub. The groove or grooves intersect with at least some of the tooth roots of the toothed profile to form a plurality of radially-extending spaced openings through the hub.
