You'll want to pull the auger out do the job but it's not a big deal. You can access the inside end by taking the covers off at the top of the feeder house. Then just unbolt the bearing flanges. To access the outer end swing the cab ladder forward and remove the shield, drive chain, and low shaft speed sensor. Unbolt the bearing and screw the auger out. The rest is bench work.
We did it exactly that way. It was a little awkward undoing the bearing flange in the auger tube above the cylinder. After that it was a cake walk turning the auger out and changing both bearings. It took us most of the day, but we are back together and ready to go. Thanks again, Hugh
