Abstract
A pinion mounting with direct tapered roller bearing arrangement for differential gear mechanisms includes a first tapered roller bearing and a second tapered roller bearing to provide support for a pinion shaft, the pinion mounting and pinion shaft being removable from the differential gear mechanism without disassembly of other components of the differential gear mechanism. The first tapered roller bearing incorporates a continuous seal and o-ring, with the first tapered roller bearing either mounted to the differential gear mechanism case by retaining a mounting flange on the bearing cup, or threaded into the differential gear mechanism case by threads on the exterior of the bearing cup. A plurality of shims are used to set the bearing preload and to dimensionally set a pinion shaft gear with a ring gear of the differential gear mechanism.
