Abstract: A pump actuator for use between a cam and a pump comprises a pump actuator body having a pad defined between a plunger facing surface and an opposite roller facing surface, where the plunger facing surface is recessed into the pump actuator body and offset from a radial end. The pump actuator body further comprises a cylindrical wall defined between the radial end and the plunger facing surface. A concave surface feature is formed on the pad on its plunger facing surface. The opposite roller facing surface of the pad is provided with a surface enhancing treatment comprising shot peening. These features, separately or in combination, provide mass-neutral improvements of the pump actuator body's fatigue life.

Abstract: A differential assembly includes a first case half. A second case half is connected to the first case half. The first and second case halves define a gear chamber. The first and second case halves each include pockets formed therein. A differential gear set is disposed in the gear chamber. First and second clutch packs are disposed in the pockets between the first and second case halves and differential gear set. The clutch packs engage the first and second case halves and the differential gear set defining a limited slip. A locking collar is disposed in a cavity formed in one of the first or second case halves. An electric actuator mechanism is coupled to the locking collar selectively moving the locking collar into engagement with the differential gear set locking the differential.
