Abstract: A slide hammer tool is particularly useful for replacing worn teeth of a trenching machine. The teeth are retained in chain links of the trenching machine by respective open keeper rings. The tool has a rod with stops proximate both ends. A hammer is slidable on the rod between the stops.
