Thanks for responding Brian. What were some of the settings as far as clearances and cylinder speeds compared to the old rotorIJ Also, I am having some trouble zeroing the concave out as in the included instructions. I installed a new Agco high wire concave before installing the CDF and the sides of the concave frame hit the solid part of the cage before I can zero the cylinder bars against the concave. They get real close, about a quarter inch away from the concave but will not touch. Of course, one dealer I talked to says they have installed a lot of CDF's and have never run into this. All parts are Agco so what is the dealIJ I would like to ask you some more questions about the installation if you don't mind ,could you email me your contact information if you would like to help. Thanks. My email is rodander@onawave.net
