Hi I am working on my9750 sts and find the top feeder house shaft is pounded out by the keyway and a chip if steel is broken off result is that the slipclutch is a little loose, does anyone know is the 9760 has a better or thicker shaft? I don't like to put it back in the way it is, too much work to repair it during harvest if it were to break, anyone else had this problem?
