like was said before the pulley is not hard if you have a good puller. I didn't have one so I used a porta power and a thick flat steel plate. I first took the smaller pulley off of the big one , then drilled holes into the plate to match up with the ones in the big pulley. then I got some threaded rod, stuck them through the plate, and screwed them into the big pulley, put the ram between the plate and shaft, and she came right off. And do BE CAREFUl, the pulley is heavy, and in kind of an awkward place to boot. To make it easier to handle, I removed the grate on the deck between the cab and grain tank. This right above the pulley. I then attached a rope to the pulley run it up over a pulley mounted to a truss above, and back down along the side of the machine. I then tied a 75n weight to the other end, and I was able to lift and align the pulley back to the shaft with little effort. Good luck Joe
