Abstract: A cylinder liner sleeve puller has four legs having flanged feet at their bottom and being connected by four pivotably mounted pivot arms. The arms are pivotably connected to a central hub, which arrangement forces the lower ends of the legs outward when the hub is manually moved downward. In operation, the legs are inserted into the cylinder so that their bottom extremities are below the lower end of the liner sleeve. The hub is then pressed downward, forcing the lower ends of the legs outward until the flanged feet are directly below the liner sleeve. A jack support plate having spaced holes for the legs is then passed over the legs and rests on the engine block. A hydraulic jack is placed on the support plate, and a top plate is fastened to the top of the legs. When the jack is activated, the plunger pushes the top plate upward, causing a corresponding upward movement of the legs, thereby removing the liner sleeve.

In cross section shank (24) of tool (20) includes a pair of major sides (26) disposed in spaced parallel relationship to each other, and a pair of minor sides (28) also disposed in spaced parallel relationship to each other. The minor sides (28) are disposed substantially perpendicularly to the major sides (26) and are spaced apart from each other substantially the same distance separating the major sides (26). Two pairs of intermediate sides (30) extend diagonally from each end of major sides (26) at an angle of approximately 120.degree. to intersect an adjacent end of a corresponding minor side (28).

Abstract: A driving tool and fastener, in the driving end of which is provided a nick or slot for insertion of the driving tool for driving the fastener, are provided which, because of their particular, respective cross-sectional configurations, can be interlocked temporarily together. As this interlocking engagement prevents the driving tool from accidentally slipping from the nick in the driving end of the fastener, rotational movement of the fastener is greatly facilitated. The shank of the driving tool is provided at its operative end with a bit that, because of its cross-sectional configuration compared to that of the nick, wedges with the nick. Thus, not only is slipping between the driving tool and fastener prevented when rotating the fastener, but accidental separation of the driving tool from the fastener is prevented, making the task considerably easier when using the fastener in overhead work or in a hard to reach location.
