We had one of the wear plates on the elephant ears on front of rotor come loose today, machine has 800 eng. hours. It tore up puter peice inbetween rotor and feeder house, we put it back together and stuffed crap in hole and kept going. It looks like a big job to fix it right proabably worth checking bolts on wear plates. I keep having problems with tailings belt coming off. proabably at least twice a day, I have all sheilding in place has anyone had this problem? Iam running 9860 with 8010 had one sensor problem so far, capacity and everything else is comparable.
