Abstract
A tool includes an actuator assembly, a rod, a first nut, and a second nut. The actuator assembly includes a cylinder, a ram, and a bore extending through the cylinder and the ram. The cylinder includes an internal chamber supporting the ram, a first end, a second end, and a reaction surface positioned proximate the first end. The ram is movable relative to the cylinder and positioned adjacent the second end of the cylinder. The rod extends through the bore of the actuator assembly. The first nut is selectively coupled to one of a first end of the rod and a second end of the rod, and defines a first dimension larger than the bore width of the bit block. The second nut is selectively coupled to the other of the first end of the rod and the second end of the rod, and defines a second dimension less than the bore width.
