Starting at the front, the throat pan liked to wearout and the conveyor chains should be well looked over. The cage and bars should be checked for condition, if you can purchase it cheap enough, Hyperize it. The accelerator rolls and chains_gears and bearings wear out. The N6 has a front overfeed auger that can have pan and bearing problems, easy to see and get at from inside the graintank. Alternators can be difficult on these machines, they had several styles over the years, some swear by the Neioff and some swear at them. I believe that all SIII had the Ambac A100 pump and Bosch nozzles this is something to have, Rpms are slowed on the N6 for much longer engine life. Since you don't know how it was run with 2000 engine hours, do the Underhaul, it's real cheap insurance. Check the discharge impeller_chopper for wear. And last but not least look over the main clutch shaft and clutches, left side under the cab_grain tank area. Shafts, clutches and bearing can get expensive. Hard stops bent, broke, or damaged these shafts for future repair. Previous owner bent mine and it didn't help the bearings.$$$ The N6 is the better of the two for capacity for several reasons. I looked at both too and chose the N6 Series III and haven't regretted it. Good luck!
