The Piston Pump Measuring Tool Alignment Plug is used during pump measurement procedures to establish accurate alignment between internal rotating components. The tool positions the port plate, barrel, and slipper retaining plate in a controlled relationship before measurement is taken. It holds these elements in a fixed orientation and allows reliable evaluation of barrel lift-off conditions. It reduces the chance of movement that can affect measurement accuracy.Attributes:• Provides alignment control without altering geometry.• Reduces errors caused by component misalignment.• Restricts unintended movement during inspection procedures.Applications: The Piston Pump Measuring Tool Alignment Plug is used during pump inspection and setup procedures to align internal components while measuring barrel lift-off shim thickness.
