The Four Circle Extruder Tool is used to apply uniform pressure during the swaging process for securing pins within their designated tracks. By ensuring accurate and consistent application of force, the tool helps to deform and reshape the pin ends, securely locking them into place within the track. The tool allows for efficient and repeatable operations, making it ideal for use in high-demand environments.Attributes:• Ensures accurate alignment of positive pins during extrusion.• Ensures a uniform extrusion process for all pins.• Minimizes the risk of pin displacement during operation.Applications: The Four Circle Extruder Tool is used during the undercarriage field maintenance process, for swaging pins in the positive pin retention track system, ensuring secure and durable pin placement.
