Did it eat alot of dirt to wear that fastIJ 1600 sep hrs we did feederhouse floor, second chain first sprockets, clean grain boot, lower clean grain auger, first shaker bushings and shaker drive Now at 2200 sep hrs it needs elephant ears, cone bolts, and maybe cone. still on first sieves. We cut corn, wheat and milo, (more corn than anything) I leave the front drum in the top corn position and middle lower position all the time. That may help on feeder house wear. One thing i did when rebuilding shaker drive, i welded jump clutch ratchets to the hubs (not to each other) this takes out slack between the 4 lugs on the ratchets and hub. I also got .006 inch shim stock and put around hex shaft between shaft and hub and put locktite in it to remove all slack. That made the sieves run real smooth and quite (no banging and flopping)
