  • Hydraulic cylinder reconditioner
    Patent number: 4502316
    Abstract: A hydraulic cylinder reconditioner has a base to dispel radial forces not directly under a dent and a piston on the base to bear radially outwardly under a dent to remove the dent without substantially distorting the original dimensions of the remainder of the cylinder. A method of using this reconditioner allows hydraulic cylinders to be quickly reconditioned rather than to be discarded when dented.
