ABSTRACT:
An installation tool for pin and collar fastener assemblies includes an ejector rod slidably mounted in an axial blind bore in the actuator portion of the tool. Within the blind end of the axial bore is an elongated resilient bumper adapted to engage the ejector rod to absorb momentum and energy associated with high speed movement of a severed pintail. The resilient bumper minimizes shock loading of the ejector rod and thereby prolongs the ejector rod service life.
