Have an M2 with a 16' LMG head. The conveyer auger fingers have started tapping the feeder beater fingers (kocked out 5 auger fingers and only one got a chopper knife) The fingers appear to be in line with each other. How are they supposed to be. In line with clearance or offset to pass by each other. Or could the finger timing have changed somehow if so what is correct timing. Help appreciated.
