Abstract

See full text

Methods and apparatus for changing actuator output torques are disclosed. An example method includes decoupling a first end cap from a body of an actuator. A first spring assembly is positioned within a first outer chamber defined by the first end cap and the body. A first end of the first spring assembly is positioned adjacent a surface of a first piston. A second end of the first spring assembly is positioned adjacent the first end cap when the first end cap is coupled to the body. The method includes positioning a first spacer within the first outer chamber and coupling the first end cap to the body. The first spacer changes a distance between the first and second ends of the first spring assembly when the first end cap is coupled to the body to change an output torque of the actuator.
