The Piston Pump Measuring Alignment Plug is a pump measuring tool to establish correct positional alignment between internal rotating components during inspection and setup procedures. It is used while determining the required shim thickness for pump barrel lift-off by holding the port plate, barrel, and slipper retaining plate in a fixed and aligned relationship. The tool ensures that measurement readings reflect true operating geometry rather than misaligned conditions.Attributes:• Enables accurate assessment of internal pump clearances.• Ensures proper spacing relationships are evaluated accurately.• Reduces measurement variation caused by component misalignment.Applications: The Piston Pump Measuring Alignment Plug is used during pump inspection and setup processes where internal alignment is required to measure barrel lift-off shim thickness accurately.
