Claims3
A tool for removing a sleeve from a mounting structure in which the sleeve has an elongated bore and a plurality of openings along the length thereof, said tool comprising an elongated shank with a head at one end and an anvil at the opposite end, said head being of a size to be slidably received within the bore of said sleeve, movable means carried by said head and engageable with the openings in said sleeve, clamp plate means movably mounted on said shank in spaced relationship to said head, means for securing said plate means to said sleeve for clamping said tool thereto, and impact imparting means slidably mounted on said shank intermediate said anvil and said clamp means, whereby movement of said impact imparting means against said anvil causes an outward force to be applied to said sleeve to remove the same from the structure in which it is mounted.
A tool for removing a cylinder liner from an engine block having a piston slidably mounted within the liner, the liner having an elongated bore and a plurality of openings along the length thereof, said tool comprising a head of a size to be received within the bore of said liner, at least one dog means slidably mounted within said head and having resilient means normally urging said dog means outwardly into the openings of said liner, a portion of said dog means normally located exteriorly of said head but being retractable therein, an elongated shank connected to said head, clamp plate means movably mounted on said shank in spaced relationship to said head and selectively engageable with said liner, a nut threadedly engaging said shank and adapted to engage said clamp plate means to firmly attach said head and said clamp plate means to said cylinder liner, a sliding hammer movably mounted on said shank, and an anvil fixed to the end of said shank remote from said head in a position to be engaged by said hammer, whereby when said tool is attached to said cylinder liner the piston engages said head to raise said cylinder liner partially from the engine block and movement of said hammer against said anvil completes the removal of the liner from the block.
