During component inspection and shop service, technicians select specialized precision instruments based on the exact type of clearance or dimension being evaluated. Match each precision measurement instrument to the measurement task it is designed to perform.
- Feeler gaugeMeasuring narrow gaps and clearances between two mating parts, such as spark plug electrode spacing
- Outside micrometerMeasuring the external diameter or thickness of solid components, such as a valve stem or wrist pin
- Dial indicatorDetecting minute surface variations and axial movement, such as brake rotor lateral runout or shaft end play
- Telescoping gaugeTransferring internal hole or cylinder bore dimensions to an external precision measuring tool
Answer
Feeler gauge matches measuring narrow gaps; Outside micrometer matches measuring external diameter or thickness; Dial indicator matches detecting minute surface variations and runout; Telescoping gauge matches transferring internal bore dimensions.
Each instrument is paired with its specific shop role: feeler gauges check gap thicknesses, outside micrometers measure external component sizes, dial indicators read surface runout, and telescoping gauges transfer bore dimensions.
