Abstract: A remanufactured planet carrier (11) is disclosed having a first plate (12) and a second plate (13) spaced apart from and oriented generally parallel to the first plate (12). Supports (28) join and support the first (12) and second (13) plates. The remanufactured planet carrier (11) further has a plurality of first pin bores (14) in the first plate (12) and a plurality of second pin bores (15) in the second plate (13). The first pin bores (14) are parallel and generally aligned with the second pin bores (15). A cylindrical member (17) extends from a central axis of the second plate (13) away from the first plate (12) with a shaft bore (16) formed within the cylindrical member (17). The first (14) and second (15) pin bores and the shaft bore (16) each have a surface layer (26) with a hardness of at least about 180 BHN and a strength of at least about 500 MPa.
