Piston Pump Measuring Tool Test Ring Caterpillar 1282745

The Piston Pump Measuring Tool Test Ring maintains a controlled relationship between these components. The ring allows measurement of pump barrel lift-off conditions without the influence of adjacent parts. This alignment control supports the determination of shim thickness by keeping the barrel and related elements in a stable measurement position during inspection routines. The ring allows repeatable measurement steps by maintaining the same component relationship throughout the procedure, supporting comparison during inspection and adjustment activities.Attributes:• Supports measurement of pump barrel lift-off conditions.• Controls the relative position of internal pump components.• Enables stable measurement reference conditions.Applications: The Piston Pump Measuring Tool Test Ring is used during piston pump service procedures to hold alignment between the port plate, barrel, and slipper retaining plate while determining pump barrel lift-off shim thickness.
