5.5mm Diameter Piston Pump Head Spring Pin Caterpillar 6041719

The Piston Pump Head Spring Pin holds spring-loaded assemblies within the pump head in place. It ensures that internal components maintain their position under dynamic pressure changes and reciprocating forces. Its tight tolerance fit minimizes play and prevents premature wear or dislocation of key parts. Maintains positioning of spring-loaded components in the piston pump head to ensure operational stability and internal alignment under pressure cycles.Attributes:• Maintains internal alignment under fluctuating pressure.• Retains position during piston pump actuation.• Provides rigid axial locking for spring components.Applications: The Piston Pump Head Spring Pin is installed inside the piston pump head, seated in cross-bores or grooves where it locks the spring assembly relative to the cylinder block or valve plate.
