Generator for a vehicle

A generator, comprising:

• a housing that defines a housing region and a fluid passage that forms a portion of a fluid circuit and includes an outlet in fluid communication with the housing region;
• a pump configured to convey fluid along the fluid passage;
• a bearing disposed about the pump;
• an alternator having a stator and a rotor disposed within the housing region;
• and
• a hub configured to receive torque for rotation about an axis, the hub being coupled with the rotor, such that rotation of the hub about the axis drives rotation of the rotor about the axis, and being coupled with the pump, such that rotation of the hub about the axis operates the pump, wherein the hub defines an interior volume and comprises:
• a bearing carrier engaged with the bearing, such that the bearing supports and facilitates rotation of the bearing carrier relative to a portion of the pump, wherein the bearing carrier defines an access opening that extends through the bearing carrier from the interior volume to an exterior environment of the hub, and the bearing carrier includes a collar portion proximate to the access opening and having an inner surface that defines a hollow in the exterior environment of the hub and includes a tapered portion that tapers radially inboard as the tapered portion of the inner surface extends axially away from the access opening.
