ABSTRACT:
A method and apparatus are disclosed for removing a rotor of a rotary machine, such as a rotary combine harvester. The method comprises the steps of exposing one end of the rotor while ensuring that the rotor remains safely anchored within the machine, securing to the exposed end of the rotor a plate that is mounted on a support block carried on the lifting platform of a movable lifting device, disconnecting the rotor from all remaining components of the machine to permit the rotor to be slid out of the machine, and moving the lifting device away from the machine while simultaneously controlling the height of its lifting platform to cause the end of the rotor to move along a path parallel to the axis of the rotor and thereby extract the rotor from the machine while supporting the weight of the portion of the rotor projecting from the machine.
