A Dial Indicator Base serves as a calibration tool for sleeve metering fuel pumps, providing a stable platform for proper adjustment and measurement. It holds the fuel pump securely, allowing it to set and verify fuel delivery accurately. Maintaining the pump in a fixed and controlled position ensures calibration can be performed repeatedly with consistency, reducing errors caused by misalignment or movement.Attributes:• Ensures precision alignment between the pump and the indicator tool.• Minimizes deviations caused by manual measurement errors.• Ensures uniform fuel distribution during calibration.Applications: A Dial Indicator Base is positioned under sleeve metering fuel pumps to hold them securely during calibration, ensuring accurate fuel delivery adjustment and pump timing.
