Manual override for steering actuator

A steering actuator including a housing and a motor located within the housing, the motor including a stator and a rotor rotatably supported within the stator, the steering actuator further comprising:

• a rotor shaft supporting the rotor and including opposing input and output ends extending from respective ends of the stator, the rotor shaft supported for rotation about a rotor axis defining a longitudinal direction of the steering actuator;
• a driven gear supported on the input end of the rotor shaft for rotation with the rotor shaft;
• an override structure supported for rotation within the housing, the override structure including an override shaft and a drive gear;
• the drive gear supported for rotation with the override shaft wherein the drive gear is longitudinally movable relative to the driven gear to engage and disengage the drive gear relative to the driven gear;
• a coupling structure on an end of the override structure for engagement with an auxiliary driver located outside of the housing for providing a rotational driving force to the override structure and effecting rotation of the rotor shaft;
• a boss extending from an interior surface of the housing and surrounding the override shaft, and the boss having a castellated end distal from the interior surface and defining notches;
• a tine structure extending radially from the override shaft and longitudinally positioned for engagement with one or more of the notches in the castellated end;
• and
• the override shaft supported to the housing for movement in the longitudinal direction to position the tine structure in engagement with and in disengagement from the one or more notches.
