It's not a very difficult project at all. Aside from unhooking belts and hoses there is basically two bolts that holds the feederhouse on. We made screwjacks to support it from underneath, then unhook everything that needs to be unhooked. On each side of the feederhouse there is a bolt (roughly 1 1_8) that holds a cast iron u shaped piece onto the frame. Make sure everything is supported very well, remove the bolt and the cast iron piece on both sides and back away. We only back up about 5 feet so we are out of the way of the feeder house should it decide to fall (been there)and do your work. This makes re-attaching easier. It's almost easy to get to the cylinder, but it still has the air of John Deere inconvienence... There shouldnt be any need to farm this out if you are least reasonably competent working on projects. Good luck
