ABSTRACT:
For use in combination with a work roll mounted on the end section of a shaft by means of a sleeve member axially inserted in a wedged operative position therebetween, a fluid actuated tool assembly removably engageable with the shaft and sleeve member for axially moving the sleeve member into and out of its operative position. The tool assembly preferably comprises a piston contained in a cylinder which during use is movable axially relative to the piston. At a first end of the tool assembly, the piston is removably attachable to the shaft and the cylinder is arranged to abut the sleeve. At an opposite second end of the tool assembly, the cylinder is removably attachable to the sleeve, and the piston is arranged to abut the shaft. The piston and cylinder have cooperating internal surfaces arranged to define a chamber adapted to receive fluid under pressure, the said fluid pressure being operative to move the cylinder relative to the piston. Depending on which end of the tool assembly is being used, the aforementioned cylinder movement will produce a corresponding movement of the sleeve member into or out of its operative position between the shaft and the work roll.
