摘要： A ring installer and method for installing piston rings on a piston includes an axial pusher, a radial pusher and a translating device. The axial pusher axially moves a cartridge of piston rail rings to position an end rail ring of the piston rail rings into a preinstall position. The radial pusher radially enlarges the end rail ring to separate the end rail ring from the piston rail rings. The translating device receives the end rail ring from the radial pusher and axially moves the end rail ring to an install position that is axially spaced apart from the cartridge of piston rail rings and from the preinstall position wherein the end rail ring is in alignment with a piston groove of the piston.

摘要： An apparatus is provided for squaring a piston ring for fitting within a cylinder bore of a combustion engine. The piston ring squaring apparatus comprises a body including a first body portion and a second body portion. The second body portion is pivotally connected at one end to an end of the first body portion. Means are provided for biasing the first body portion away from the second body portion. The piston ring squaring apparatus allows the piston ring to be squared and supported when the piston ring is in the cylinder bore being measure for ring end gap.

摘要： 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.

摘要： An expander device, particularly for use in expanding springs, piston rings, circlips and similar objects, comprises a support member and an actuating member which are pivotally connected to one another and equipped with handgrip portions. A pair of expanding jaws is mounted on the support member for pivoting in a plane which is parallel to the axis of pivoting of the actuating member relative to the support member. A transmission converts the pivoting of the actuating member into spreading apart of the jaws, the transmission including a ratchet mechanism which includes a toothed rack mounted on a guide track for movement in the frontward direction of the device, a transporting pawl which is actuated by the actuating member so as to engage the teeth of the rack and to move the latter, and an arresting pawl which arrests the rack against movement in the rearward direction of the support member. Connecting links are pivoted to the rack, on the one hand, and to the jaws, on the other hand and cause the jaws to spread apart as the rack moves in the frontward direction so as to expand an object extending between the free ends of the jaws. The jaws may include separate lever and jaw elements, and additional connecting links may be provided which pivotally connect the respective jaw element with the other lever element on which the other jaw element is pivoted. The additional links may be guided on the other lever elements in elongated slots, and arrested in a plurality of positions in such slots.
