An apparatus for testing a rock drill has a base structure, a displaceable structure movable toward and away from the base and a fluid pumping mechanism carried on one of the structures to be driven by the rotation of the rock drill. The air leg of the rock drill is deemed either operational or in need of repair based on whether attempted extension of the leg is sufficient move the displaceable structure away from the base. A control mechanism in a fluid passage fed by the pump output is closable so that a pressure builds up in the passage under operation of the pump. Successful of unsuccessful buildup of the pressure to a sufficient level reflecting good rotational operation of the drill reflects whether the drill component is to be deemed operational or in need of repair. Quick and simple testing of both the leg and drill components is facilitated.
