To what precision must the fueling pump and motor in the Type 3 system be aligned?

In the Type 3 fueling system, the precision required for aligning the fueling pump and motor is critical to ensure efficient operation and minimize wear and tear on the components. Achieving an alignment precision of .002 inch is necessary to prevent issues such as excessive vibration, which can lead to premature failure or breakdown of the pump and motor.

Alignment at this level ensures that the drive shaft is properly positioned, allowing for smooth operation and efficiency in transferring fuel. A .002 inch tolerance helps maintain optimal performance, reduces the risk of leaks, and enhances the overall longevity of the equipment. Therefore, maintaining this precision in alignment is crucial in preventing operational problems and ensuring system reliability.
