ABSTRACT:
A percussive tool, such as a tamping tool used with railroad bed tamping apparatus, has a replaceable work bit, such as a tamping foot. The removable tamping foot is secured to a shank by a tapered force fit. A repulsive force is generated between the shank and the tamping foot when it is desired to remove the tamping foot from the shank. Production of the repulsive force is achieved by pumping a fluid into an expandable chamber between the shank and the tamping foot. Preferably, a hand-operated grease gun drives grease into the expandable chamber to produce the repulsive force.
