Abstract:
A hammerless attachment assembly for releasably maintaining a ground engaging tool and an adapter in operable combination relative to each other, with said ground engaging tool defining an open ended blind cavity between multiple sides, said hammerless attachment assembly comprising:an insert nonrotatably fitted within a recess defined on a side of a nose portion of said adapter, said insert defining an internally threaded bore; a rotatable fastener having a head portion and an externally threaded shank portion, said shank portion of said fastener being sized to extend lengthwise through an opening having a closed margin defined in a side of said tool, with the opening in the side of said tool generally aligning with the internally threaded bore in said insert when said tool is positioned on the nose portion of the adapter, and with the externally threaded shank portion of said fastener forming a threaded juncture with the internally threaded bore on the insert such that, in response to rotation of said fastener in a first direction, said insert is drawn toward and ultimately moved into clamping relation with an interior side surface of said blind cavity while remaining, at least partially, within said recess, thereby releasably maintaining said tool and adapter in operable combination relative to each other; and wherein elastomeric material is disposed in operable combination with said rotatable fastener and said insert for inhibiting contaminants from adversely effecting said threaded juncture whereby facilitating rotation of said fastener in a direction opposed to said first direction when said tool is to be released from operable combination with said adapter.
