Abstract: A tool for removing a piston ring from a piston is provided. The tool includes a handle portion, an elongate portion, and a working portion. The elongate portion defines a longitudinal axis. The working portion includes a first section and a second section coupled to the first section at a pivot region. The first section is coupled to the elongate portion and is inclined at a first angle relative to the longitudinal axis. A retaining member protrudes from the first section. The second section includes a leading edge. A thickness of the second section decreases continuously from the pivot region to the leading edge and a width of the second section increases continuously from the pivot region to the leading edge. The working portion includes a ramp member extending from an upper surface of the second section. The ramp member includes an engaging surface to engage a piston ring.
