ABSTRACT:
A transmission casing embodying the concepts of the present invention has a one-piece body portion with front and rear faces. The first of two major openings penetrates the front face, and the second of the two major openings penetrates the rear face. A pair of axially spaced front and rear drive gear bearing supports are provided in the transmission casing, and the drive gear bearing supports are axially accessible through the first major opening. A pair of axially spaced front and rear idler gear bearing supports are laterally displaced from the respective drive gear bearing supports and the idler gear bearing supports are also axially accessible through the first opening. A final drive bearing retainer is demountably secured within the second major opening. A final drive rear bearing support is carried by the final drive bearing retainer. An aperture for receiving the final drive front bearing support penetrates the first face and is aligned with the final drive rear bearing support.
