ABSTRACT:
In ground engaging tools, reliable fastening devices are needed to quickly and effectively secure replaceable earth working tips to adapters. The fastening pin assembly should be configured in such a way as to prevent pin loss or breakage which causes the tip to be lost and/or the adapter damaged. This invention consists of two pins and an interconnecting and retaining means. When assembled, each pin will extend approximately to the middle portion of the adapter through axially aligned bores defined in both the tip and adapter. The interconnecting and retaining means is located in the middle portion of the adapter between the two pins and retains the pins in the adapter bore. This invention protects against pin loss/and or breakage and is beneficial to all type of earth working replaceable tip applications.
