Many new parts!!. Sieve, chaffer, hangers, the whole pan, fan shaft, fan pulley (faster shake ) ect. Small mods on sub frame, move chaff spreader back and extend....... Was $$$$$$ but wanted to bring up to new specs. Traded in couple of years to get Cummins, witch has much better "hang" torque. Was it worth itIJIJIJIJ Did do Canola better. Able to use more air on wheat and barley so very clean sample. Wish I would have tried to open chaffer up before installing the long shoe like I do now. E-mail if you need more info.....
