Abstract
A tool for extracting a glow plug includes an externally threaded shaft, an internally threaded sleeve that engages the externally threaded shaft, and a fixed cavity formed in one end of the externally threaded shaft. The cavity has a side entry to permit the insertion of the glow plug into the cavity in a direction normal to the shaft, and a pair of opposing shoulders integrally formed in opposing sidewalls of the cavity to engage the glow plug. The sleeve threads down the shaft until it contacts the engine block. Rotating the sleeve exerts a pulling force on the shaft, which is transferred to the inserted glow plug by the opposing shoulders in the cavity. This pulls both the shaft and the inserted glow plug away from the engine block.
