Abstract
A spark plug electrode gap setting pliers is provided. The pliers include a first jaw portion coupled to a first shim and a second jaw portion coupled to a second shim. Upon actuation of the pliers, the first and second jaw portions close in parallel to bend respective electrode supports of a pair of electrodes or to bend the pair of electrodes to provide a parallel gap between the pair of electrodes.
Claims17
Spark plug electrode gap setting pliers, comprising:
- a first jaw portion coupled to a first shim;
- and
- a second jaw portion coupled to a second shim;
- wherein, upon actuation of the pliers, the first and second jaw portions close in parallel to bend respective electrode supports of a pair of electrodes or to bend the pair of electrodes to provide a parallel gap between the pair of electrodes, and wherein the first and second jaw portions are each configured to interchangeably couple to shims of different thicknesses to provide different parallel gap distances between the pair of electrodes upon actuation of the pliers.
