John Deere ran a 250 in some of their smaller combines. I don't know about the 292. Gleaner and Massey Ferguson ran a lot of 292's. They are no different from the one used in trucks. Combines are a good source of engines. They are run at a constant rpm and if they have been serviced at all, most are in decent shape. I have helped do three combine engines and only one of the three had to have the crank turned and that was only enough to clean it up. Hope this helps.
