Zusammenfassung:	A drive unit is disclosed that includes case portions, a gasket interposed between the case portions, shafts, bearings having respective bearing races, and a bearing shim plate. One shaft includes an input oil tube which provides a fluid pathway between the bearing shim plate and a rotor of the drive unit. Interposed between bearings, and the bearing shim plate, are shims. An approach for sizing shims for use with a drive unit is also disclosed, the approach including determining the distance from a mating flange of a case portion, to different bearing races, selecting shims based on the determined distances, and attaching the bearing shim plate to the case portion with shims interposed therebetween.
