In certain cases, because dimensions are not standard, it is sometimes necessary to file off about 2mm at the end of the 5th arm. For this, see photo 8. This is the arm opposite the Shimano standard crank, the one behind the standard Campagnolo crank. This is done so that the chain can rest on the bottom of the plate groove and not on the edge of the  5th star.
