Abstract: An improved system and method for removing extrusion screw elements includes a puller assembly for removing at least one screw element from a screw shaft of a screw-type extrusion machine. The at least one screw element includes a sleeve portion received annularly about the screw shaft and at least one flute extending radially outward from the sleeve portion. The puller assembly includes a body having a sleeve portion with an inner diameter sufficiently sized for axially fitting over the at least one screw element on the screw shaft. At least one engaging element is removably secured to the body for enabling the body to be axially installed on the at least one screw element when the at least one engaging element is removed from the body and axially locking the body on the at least one screw element when the at least one engaging element is installed in the body.
