Apron Cross Feed Gear Do to the tolerance stack up of the mating parts, South Bend used standard, oversize, and under size crossfeed gears in the apron. The fit was established in final assembly for the right backlash to the crossfeed screw. You may be experiancing interfearance due to no backlash. There should be a number stamped on your crossfeed gear (std, m10, p10, etc.) You might need a smaller one. Ted **********
