Abstract
An actuator includes an end fitting, a ball screw connected to the end fitting, a ball nut engaged with the ball screw, a rod disposed at least partially within the ball screw, and a rotating member engaged with the rod. A method of verifying an actuator may include rotating a manual input portion in a first direction under substantially no load until the manual input portion stops, rotating the manual input portion in a second, opposite direction until a first torque is measured, determining a first rotational angle at which the first torque was measured, rotating the manual input portion in the first direction until a second torque is measured, determining a second rotational angle at which the second torque was measured, and verifying a second load path if a backlash is within a predetermined range.
