ABSTRACT:
The invention is directed to a device for axially and externally mounting an expandable sleeve onto, and dismounting the sleeve from, a cylinder. The subject device comprises an external fluid-transmission means for expanding the diameter of the expandable sleeve by introducing a fluid capable of expanding the sleeve between the inner surface of the sleeve and the outer surface of the cylinder. The requisite sleeve expansion is accomplished without transmitting fluid from within the cylinder during the mounting and dismounting operations. The sleeve is contractable by the removal of the fluid.
