Auger not working on Toro snowblower
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 couple of hundred dollars.
