A bearing surface portion surrounds the large end opening and is fabricated of a non-ferrous powder metal material of a second composition different than the first non-ferrous composition. The first and second compositions are compacted and sintered together with the second material of the bearing surface portion surrounding and being localized about the large and opening. |
