one more thing... on F2 -3's after a few seasons CHRECK THOSE RPM's... At high idle the fan shaft should be 1100 rpm and 1000 rpm at 2300 eng rpm.. don't trust the tach in cab unless its digital then I would verify.. a decrease of only 100 rpms on fan shaft will drastically reduce capacity of machine... Many times I have gone to field in corn and seen shucks coming over the cleaning shoe---99.9% of time its low rpm.. these machines must have walker and fan rpm to mechanically and air suspend material to allow it to separate properly...
