A service tool for dislodging circumferentially spaced, longitudinally extending fingers of a flangeless retainer of a valve stem seal from a valve guide of an internal combustion engine, the guide of the type having circumferential detents for retaining radially inwardly turned ends of the fingers. The tool includes an exterior shell formed of two symmetrical halves divided along a longitudinal axis. The shell is coupled to a cylindrical puller element that is encased within and axially movable in the shell; the puller element also comprises symmetrical halves longitudinally divided along same axis. The puller element halves are hinged, and each of the puller halves contain gear teeth for reacting with separate worm gears contained in shell halves and attached to levers. Manual movement of the levers causes cams in radially inwardly turned arms at opposite end of the puller to dislodge the fingers of the seal retainer.
