The adjustment assembly comprising a link pivotally mounted to the side of the combine and circular camming disc which is located in the link. The camming disc is provided with a sleeve which projects into the combine and which is operatively coupled to a transversely extending hexagonal shaft. The concave grips the sleeve and in response to rotation of the camming disc the spacing between the concave and the threshing cylinder is changed. The concave is pivotally coupled to the side sheet of the combine by a cylindrical bushing having a slot into which is inserted a loosely fitting retainer plate.
