Removed and disassembled auger and gearbox per your tube video. Carefully cleaned gearbox of brass gear filings. Checked output shaft to ensure it is not ruined. I ordered brass gear and seal which arrived quickly through ereplacement parts. Reassembled using EP00 grease. Fairly simple as long as you keep parts in order and saved a c ouple of hundred dollars.
