Hydraulic unit

A hydraulic unit, comprising:

• a housing;
• a pump disposed in the housing;
• a motor disposed in the housing and operably connected to the pump such that the motor is driven in response to fluid pressure delivered to the motor from the pump;
• an output shaft operably connected to and driven by the motor, including:
• a body having a first end and a second opposite end;
• and
• a first flange and a substantially identical second flange integrally formed with the body of the shaft adjacent the second end, the second end of the body having an outer diameter of 0.990±0.005 inches (2.515±0127 cm), the first flange and the second flange each having an axial length parallel to a longitudinal axis of the body of about 0.085±0.010 inches (0.216±0.0254 cm) the first flange and the second flange having an outer diameter of 1.359 inches (3.452 cm), the first flange and the second flange being separated by from one another by a distance of about 0.3162 inches (0.8031 cm);
• wherein a portion of the body between the first flange and the second flange has an outer diameter of about 1.2013 inches (3.051 cm);
• wherein:
• a relief is formed about a circumference of the body, a first portion of the body extending between the first end and the relief, a second portion of the body being arranged adjacent the relief, opposite the first portion, and a third portion of the body extending from adjacent the second flange towards the first end;
• and
• an outer diameter of the first portion is 0.6680+0.000−0.0005 inches (1.697+0.000−0.0013 cm), an outer diameter of the second portion is 0.703±0.010 inches (1.786±0.0254 cm), and an outer diameter of the third portion is about 0.810±0.010 inches (2.057±0.0254 cm);
• wherein:
• a plurality of first splines are integrally formed with an exterior of the body between the second portion and the third portion;
• a first end of the first splines located a distance of 1.269±0.010 inches (3.223±0.0254 cm) from a first surface of the second flange;
• and the plurality of first splines has an axial length of about 0.676±0.035 inches (1.717±0.089 cm);
• wherein the body has a substantially hollow interior and an inner diameter of the hollow interior adjacent the first portion, the second portion, the plurality of first splines, and the third portion of the body is about 0.517±0.010 inches (1.313±0.0254 cm);
• and
• wherein a plurality of second splines are integrally formed with an interior surface of the body adjacent the second end, a first portion of the hollow interior being defined by the plurality of second splines such that the first portion of the hollow interior has an inner diameter of about 0.760±0.010 inches (1.930±0.0254 cm).
