I bought a 1460 with about the same hours a couple of years ago. This is what I was told to look for. like any combine- check belts, chains, pulleys, and sprokets for wear. Check concaves, rasp bars, grates, augers, ect. for wear. Put the rotor in neutral, open the panels on the left side, and open the concave clear up. Spin the rotor by hand several times. You may want to put a mark on it. It shouldn't stop in the same place. If it does it is out of balance. This could be just a missing bolt, or a hole in the rotor, that has been patched, but not balanced. If you put the rotor in high and run it and speed it up to 900-100rpm and it doesn't shake the combine bad it should be ok. Open the panels above the feeder house(1_2" wrench) check the transition ( $900+ new)for bent vanes holes and wear. If it is grooved along the vanes- its wore., elephant ears_wear bars. They can be pretty wore and still work. mine wear bars had wore back , so the leading edge of the ear had wore bad. This is wear I had a missing bolt that had thrown the rotor out of balance. Price varies I'm guessing $10 - 20,000. 20 would have to be cherry. I went from a '84 M3 to '82 1460 with more hours. love the 1460
