The 275 shares a lot of parts with the Mitsubishi MT300 including the engine. I was recently looking at my Mitsubishi manual and comparing it to the 275 parts diagrams on the Case IH parts website and was surprised how much crossover there was between the two. The 275 was made for CIH by Mitsubishi after all. Depending on what is needed, you might actually try comparing prices with one of the grey market parts suppliers. I hear a lot of people complain about parts prices but shopping around pays off in a big way, especially if you can use good used parts for some issues. I have found WEST KY Tractor Parts to be a very good source. If I ever had catastrophic engine issues ( near total rebuild, engine block,etc), I wouldn't even consider going through case, I'd just try to get a complete Mitsubishi K3M engine through someone like Bruce Laten in Lynchburg TN. I'm not saying all parts for the MT300 are going to fit the 275 but I'll bet there may even be parts that Case now says are no longer available that can be bought through Grey market parts suppliers that can get them from Japan or the crossover parts may actually be cheaper purchased as "Mitsubishi" parts. Conversely, I have purchased Case parts for my Mitsubishi....it's just good to know there are "other" options available sometimes.
