Abstract:
A tool for removing a spark plug from an internal combustion engine after such ground electrode shield has been broken away from an upper portion of a spark plug. The tool includes: a rod having a first end threaded to an interior portion of the shield; a hollow tube for receiving a portion of the rod between the first end of the rod and a second end of the rod, such tube having a stepped portion for engaging a shoulder of the engine; and an extracting means attached to the second end of the rod for generating a force axially along a longitudinal axis of the shield to remove the shield from the engine as such rod and shield are lifted by the generated force through the hollow region of the tube.
