Abstract
A boom support pendant pin retainer for an earth working machine having a retainer plate and a projection for preventing rotational, axial and coaxial movement of the pendant pin. The projection is constructed and arranged to mesh in the void between the pendant pin and an adjacent opening in the gantry structure. The projection prevents rotational movement of the pendant pin and the retainer is secured to each end of the pendant pin and adjacent to the gantry, structure to prevent axial and coaxial movement of the pin.
