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 p hone.

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.
