What tool is used to check the gap of breaker points to ensure it is at the specified distance?

The tool utilized to check the gap of breaker points is specifically the feeler gauge. A feeler gauge is designed with a series of thin metal strips of varying thicknesses, allowing for precise measurement of small gaps. When checking breaker points, it is essential to ensure that the gap is set to the manufacturer’s specifications, and the feeler gauge provides a reliable method to do so.

Using the correct thickness of the feeler gauge, a technician can slide it between the breaker points to confirm they are opening to the recommended distance. This process is critical because the gap affects the performance and timing of the ignition system.

Other tools like calipers and thickness gauges may offer accuracy but are not specifically designed for measuring gaps in this context. A torque wrench, meanwhile, is used to apply a specific amount of torque to fasteners, which does not apply to the measurement of gaps in breaker points.
