Did you look at the parts blow ups at the link given? Savage pumps, most anyway, were pretty much the same design. The ejector is screwed to the left side of the receiver on the inside. If the ejector scrfew loosens the operation of the bolt shears the screw retaining the ejector and it falls away. An easy fix but annoying if the day ends for your hunt because of it. I've replaced more than a few. Look at the Mod 30 diagram as it seems pretty common.
