Abstract

A retainer pin assembly for releasably securing a ground engaging tool (10) in position relative to an implement (20) such as an excavator bucket (23), shovel or the like. The ground engaging tool (10) is configured to fit an aperture portion (24) of the implement.
Those portions of the tool fitting about the implement define a pair of axially aligned holes (56). The retainer pin assembly (18) includes an elongated retaining pin (64) extending through the aperture (67) defined by the implement (20) and the axially aligned holes (56) in the tool (10) for securing the tool (10) to the implement (20). The retaining pin (64) of the assembly (18) is operatively secured toward a center portion of the pin (64) in positive locking relationship relative to the implement (20) to inhibit axial or endwise movement of the retaining pin (64) within the bore (67) of the implement (20).
