Abstract
A sleeve assembly for sanding, rust removing, and pit filling on a piston rod of a hydraulic cylinder or the like includes a sanding component, a rust removing component and a pit filling component. The sanding component comprises a rigid annular outer member, a resilient annular intermediate member adhesively secured to the inner surface of the outer member, and an abrasive annular inner member adhesively secured to the inner surface of the intermediate member and in interference contact with the piston rod. The rust component comprises an annular upper ring member composed of a rigid material and an elastomeric annular lower ring member having brass or bronze particles imbedded therein. The pit filling component comprises an annular upper ring composed of a rigid material and an elastomeric annular lower ring member having lead particles imbedded therein. Clamp means releasably engages the members of each of the components about the piston rod.
