    Gabby, I think #10 is a bushing that just keeps the driveshaft centered in the auger tube. It shouldn't be rough as there isn't motion there unless shear bolt shears. In normal operation, the driveshaft and auger spin together.

    I guess I'm quoting myself but editing time expired... just to be clear.

    In normal operation, the driveshaft and auger tube rotate in unison and bushing #10 is just there to provide centering. The driveshaft is driven by the large sprocket which transfer power to right side (as sitting on tractor) oval coupler which transfer power to auger through shear bolt and mating oval coupler.

    HOWEVER, when the shear bolt shears to protect those expensive gears in gearbox, the driveshaft has to spin independent of the auger tube and the bushing #10 CANNOT be rusted and freezing the driveshaft and auger together. This is why wise #49 snowthrower owners recommend removing the shear bolt once/season, squirt a bit of lube/penetrant on bushing #10 and make certain the auger can rotate while the driveshaft is stationary.

    I stand corrected. I checked the auger I am working on in the garage. It is a bushing, not a bearing. The LS bushing is galled on my auger probably from incorrectly installed locking collar. Think I found the issue with rotation of my auger.
