Abstract: The drum drive (100, 200) comprises a generally annular-shaped drum (100, 200) which extends axially within an axial opening in an inboard half (140, 240) of a wheel (130, 230). The drum drive (100, 200) has end openings (112, 114; 212, 214) at opposite ends (102, 104; 202, 204) thereof which provide access to an interior axially extending opening (122, 222) of the drum drive (100, 200). An outboard end (104, 204) of the drum drive (100, 200) includes a radially extending flange (108, 208) which defines the associated end opening (114, 214) and provides a plurality of openings (118, 218) for receiving tie bolts (150, 250) that connect the drum drive (100, 200) with the wheel (130, 230). The drum drive (100, 200) includes a plurality of circumferentially spaced-apart, axially extending splines (128, 228) which extend radially inwardly from the interior surface of the drum drive (100, 200) and into the interior axially extending opening (122, 222 ).
