  • Patent number: 8468724
    Abstract: A retaining pin assembly for an excavator tooth assembly. The retaining pin assembly has opposable locating members each having a shank portion able to be slidably insertable via a respective retaining pin aperture on opposite sides of a wear member into a transversely extending mounting aperture of a mounting nose of an excavator. Each locating member also has an enlarged inwardly convergent tapered wedge portion adjacent a normally outer end. The retaining pin assembly also has a tensionable retaining member extending between the locating members from one side of the retaining pin assembly. When tension is applied to the retaining member relative contraction of the locating members occurs to urge the wear member into engagement with the mounting nose by wedging engagement between each of the wedge portions and a rear wall of respective retaining pin apertures.
