JD 467 Belt Tracking Issue

Hello all. Was out baling today when I noticed smoke rising from top right side of baler. Took a look at things and noticed that belt is tracking far to the right when traveling over tension roller. Belt is tracking far enough to the right that the belt edge is rubbing the arm that the tension roller is mounted to. My guess is that the edge is getting hot enough to throw off some smoke. I tried adjusting the tension roller as described in tech manual, but belt continued to track to the far right. Any suggestions before I call service tech?

Thanks,
Chris
