Abstract
A bottom mount pin retainer is disclosed for retaining a mounting pin detachably mounting a first member of a ground engaging tool to a second member thereof. The pin retainer utilizes a retainer assemblage that is adapted to relieve a snap-ring employed for retaining the pin from high axial loads in an upward direction while preventing axial movement of the pin in a downward direction. A non-load bearing member used has sufficient load bearing capacity to restrain the upward movement of the snap-ring during the insertion of the pin into the pin openings in order to seat the snap-ring in its snap-ring groove in the pin.
