If you are talking about the sump are of the lower unload tube...it kinda sucks to replace. Don't know if i did it the easiest way, but you have to take the drive gear box out, the horizontal augers out, and the ratchet for the concaves has to come off. Probably would make it easier to put the combine on blocks and take that tire off too, but we didn't want to do that so we faught it in. Its pretty much a 2 day job, and a 2nd person really helps too.
