Repair Difficulty:

Time Spent Repairing:

Tools Used:

Screwdriver, Socket set

The auger worm gear was stripped on my Troybilt snowblower. I found a YouTube video explaining how to do the repair.

There is an excellent YouTube video showing how to do this repair. I also replaced the belts since I already had the snowblower split. As in any repair, pay close attention to how parts go together when you take things apart. I am not a pro by any means so I have learned to label parts, lay them out in order, and take pictures with my phone.

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.

Worm gear driver the auger blades stripped

1. Watched instructional video online (Not much help).
2. Removed augers / shaft.
3. Removed gear (Was simple once I figured out it just tapped off).
4. Reassembled the gear case and auger / shaft for install. This took a couple tries and was the most difficult part of the repair. It is a very tight fit and interesting with only two hands.
5. Tightened all components and reinstalled plastic covers and chute.
6. Pulled the rope and everything worked as normal.
