do you know where we could get this bulletinFans were speed up on all the long shoes per campaign in early 1997. There was a bulletin put out in 2000 on moving the splitter to peel more air off fan and distribute it to the sieve and chaffer. I know the dealer in Newton and Iola Kansas had did some machines. I believe for the high yielding wet corn and or milo. Your R55 likely has the holes to move splitter so you would not need the templates but you will want to get ahold of bulliton in order to make the changes as described.
