Patent ID: 7032334

Claim:
A system for coupling excavation equipment components, comprising: a pin assembly configured to couple an adapter to a horn, the pin assembly configured to be received at least partially within a pin bore of the horn, the pin assembly comprising: an elongate insert defining a plug bore extending at least partially through the insert from the first end, the insert comprising: a first end proximate to a first side of the horn; a second end proximate to a second side of the horn; and a shape corresponding to a shape of the plug bore, the shape of the insert being a geometric figure having six sides of equal width; and a first plug configured to be received at least partially within the first end of the insert, the first plug comprising: a threaded surface adjacent the plug bore, the threaded surface of the first plug corresponding to a threaded surface of the insert, wherein tightening the first plug couples the adapter to the horn; and a generally cylindrical, tapered surface adjacent the plug bore, the tapered surface of the first plug corresponding to a tapered surface of the insert, wherein tightening of the first plug forces the tapered surface of the first plug along the tapered surface of the insert, to at least partially prevent overtightening of the first plug beyond an installed position.
