Spark plug removal and extraction tool

摘要

Apparatus and methods for the removing of a spark plug, or portions thereof, from a cylinder head are disclosed. The apparatus includes a lower socket with a longitudinal bore therethrough, a radial compression member disposed in the longitudinal bore of the lower socket, and a shaft disposed on a first end of the radial compression member. The radial compression member includes an internal surface defining a concavity that faces a longitudinal axis of the lower socket. The method includes compressing the radial compression member in a radial direction toward a longitudinal axis of the spark plug terminal, thereby decreasing an outer dimension of the radial compression member in the radial direction.

1. A spark plug removal and extraction tool, comprising:
a lower socket having an internal surface defining a longitudinal bore therethrough; a first threaded portion included on the internal surface of the lower socket; a radial compression member disposed in the longitudinal bore of the lower socket, the radial compression member including an internal surface defining a concavity that faces a longitudinal axis of the longitudinal bore of the lower socket; a shaft disposed on a first end of the radial compression member; a second threaded portion included on the shaft, the second threaded portion being complementary to the first threaded portion; and an upper socket having an internal surface defining a longitudinal bore therein, the shaft being disposed within the longitudinal bore of the upper socket.
