Pivot pin assembly

In a loader bucket having a bucket bracket assembly secured thereto and mounted for rotation about a loader arm assembly of an earth-working implement, an improved pivot pin assembly for mounting the bucket brackets to the loader arm assembly comprising:

• an elongated cylindrical pin having a first end face and a second end face;
• a first retaining sleeve having an inner surface and an outer surface and an interior end and an exterior end, the inner surface engaging the cylindrical pin, the exterior end of said first sleeve being secured to the first end face of the elongated cylindrical pin, the outer surface of the sleeve engaging the bucket bracket assembly of the loader bucket;
• a second retaining sleeve having an inner surface and an outer surface and an interior end and an exterior end, the inner surface engaging the cylindrical pin, the exterior end of the second sleeve being secured to the second end face of the elongated cylindrical pin, the outer surface of the sleeve engaging the bucket bracket assembly of the loader bucket, flange means extending outwardly from the exterior end of the second retaining sleeve for abutting the bucket bracket assembly, the flange means defining two spaced-apart sides;
• a sleeve bearing having an inner bearing surface engaging the cylindrical pin and an outer surface engaging the loader arm assembly, the sleeve bearing captured between the interior surface of the first and the second retaining sleeves;
• and
• a cover plate mounted on the bucket bracket assembly having a channel for capturing the flanges between the cover plate and the bucket bracket assembly for restricting axial movement of the elongated cylindrical pin, and said two spaced-apart sides retained in the channel for restricting rotational movement of the elongated pin with respect to the loader bucket.
