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 one embodiment, an elastic band encircles the legs at a level below the pivot arms, providing added stability in operation.
