Piston-removing apparatus including a frame portion, a piston-supporting portion, and an actuating portion; the frame portion including an elongated base section, an end member extending from the base section substantially perpendicular thereto; the piston-supporting portion including an upstanding member disposed along the length of the base section intermediate the ends thereof, the upstanding member extending substantially perpendicular to the base section and being disposed substantially parallel to the end member, the upstanding section including a central opening therethrough, a channel connecting the central opening with the periphery of the upstanding member at a point remote from the base section, a piston-aligning member removably engageable with the central opening in the upstanding member, the piston-aligning member including a sleeve section and a flange section, the sleeve section having an outside diameter slightly smaller than the central opening for insertion therein, the flange section being disposed adjacent one end of the sleeve section, the flange section being of a size larger than the central opening and bearing against the side of the upstanding member closer to the end member, a bore through the piston-aligning member having a diameter slightly larger than the diameter of a piston rod, a supporting section extending from the base section adjacent the end thereof remote from the end member aligned with the central opening in the upstanding member; the actuating portion including expandable mechanism positioned between the end member and the upstanding member in contact with the end member and spaced from the upstanding member.
