I purchased this old McCormick Deering Sheller (w/ fan). I would like to run it using my JD 1 1/2 hp hit & miss at the Sycamore steam show. I am looking for a belt pulley to fit the 15/16 flywheel shaft. Per the Deering owners manual they did make an 8" belt pulley for it part #2278A that could be ordered back then. Any idea were I can find a pulley that will work?
