ABSTRACT:
A tool system for replacing a glow plug (31) of a diesel engine includes a plurality of tools (55), by means of which a defective glow plug (31), which is screwed tightly into an internal thread (33) of a mounting hole (32) of a cylinder head (30) of the diesel engine, can be removed from the mounting hole (32), the glow plug (31) being arranged in a radially expanded, cylindrical depression (34) of the mounting hole (32) of the cylinder head (30). To make it possible to accurately align the individual tools (55) necessary for replacing the glow plug (31) with the central longitudinal axis of the mounting hole (32), a clamping sleeve (2) is provided, which can be inserted into the depression (34) and into which a centering sleeve (1, 20) can be pushed to concentrically align the individual tools (55, 65, 75, 85, 95). The clamping sleeve (2) can be pressed into the depression (34) to hold the centering sleeve (1, 20) in a fixed and clamping manner.
