Just bought another combine, and when we engage the feeder it has a loud bang coming from the bottom feeder gearbox. It runs perfectly fine when its running and makes no noises, but when u shut it off it almost sounds like a brake clunks in the same gear box to stop it.Any idea what this actually is and if i should be looking for a new gearbox? Its 2007 8010

Splines on the gearbox shafts getting wore? How many hours are on the machine? I know of several x120 series needing a new shaft. The splines don't engage very far into the feeder drive shaft so they wear out eventually. I think when they do them they replace the whole gearbox. I would talk to a dealer and get some advice. The gearboxes are heavy.

If it is the splines you can probably keep running it until you can't.

The feeder coasts to a stop so that noise when you shut it off is strange

Is the chain tensioned?
The 10’s were really good for long lasting splines so I doubt it’s that

A bent slat would be constantly noisey.......

Maybe you better dump the oil on the bottom and top gearboxes and if that’s okay, look closely at the Unis on the big pto shaft

do a feeder cal, go into the calibration page in the Pro 600, select feeder and follow the instructions. If that doesn't take care of it your gear box has problems. Just did one in my 8010, the stub shaft the spins were gone, was lucky, got it before the big money had to be put in.

If the bolts are installed backwards in the double u-joint, the 12 point bolts will contact the threads or the nuts on the 1/2” bolts when feeder is raised . Loud metal to metal noise and vibration. As far as top shaft splines go, shaft in gearbox is easy to replace. I suggest removing feeder first. Remove feeder gearbox, point output shat up. Remove seal, snap ring and shims. Make an adapter to go on slide hammer that will screw into shaft. And slide hammer shaft out . When done bore sight from new shaft to bearing on right side of feeder housing. Shin box if needed. Grease splines and it should last longer than the original.
