ABSTRACT:
A method is provided for achieving a desired preload on tapered roller bearings which rotatably support a gear between first and second transmission housing members in the assembly of a transmission. The bottom of each pocket which supports a tapered roller bearing is measured with respect to a mating face of the transmission case half. Shims are selected based upon these measurements so that each shim forms a reaction surface upon which the tapered roller bearings rest so that the appropriate preload is established with the case halves are bolted together.
