Abstract
A gyratory crusher main shaft assembly has a main shaft, an axially upper region of the main shaft including a tapered conical section with a protective sleeve friction fitted over the cone. To facilitate mounting and dismounting of the sleeve, at least one groove is indented within a radially external facing surface of the main shaft at the region of the cone to allow fluid to be introduced under pressure to the region between the sleeve and the cone.
