A cylinder liner removal tool (11) is shown having a gripping portion (12) capable of expanding against the inner surface of the cylinder liner (14). The gripping portion (12) has a rod (26). Concentrically disposed about the rod (26) in trailing order is a stop (32), a plate (36), a cylindrical mandrel (38), a shoulder (42), a bearing (44), and a nut (40). The mandrel (38) is hollow having a recess (52). The shoulder (42) has a plug member (66) disposed within the recess (52). Torquing down upon the nut (40) compresses the mandrel (38) between a radially extending shelf member (62) of the shoulder (42) and the plate (36). The mandrel (38) thereby expands radially outward to frictionally grip the cylinder liner (14).

1. A tool for frictionally engaging a cylinder liner for removal and insertion of the cylinder liner and a piston assembly within an engine block, the tool comprising:a rod having a leading end and a trailing end, the trailing end being threaded; a stop engaged to the leading end of the rod; a mandrel having an outer surface, the rod circumscribed by the outer surface; a shoulder having a shelf portion penetrated by the rod, the shelf portion disposed perpendicular to the rod and engaged to the mandrel; a plate disposed between the stop and the mandrel, the rod extended through the plate, the plate disposed radially inward to the outer surface of the wall; and a nut engaged threadably to the trailing end of the rod, the mandrel, the shoulder and the plate disposed between the stop and the nut, the nut having a leading position and a trailing position defined by an engagement range length along the rod, the mandrel having greater flexibility than the shoulder and the plate so that rotation of the nut toward the leading position from the trailing position axially compresses the mandrel causing the outer surface to extend radially outward thereby engaging the cylinder liner.
