Love all the OSHA compliant PPE
This repair would work. For a while. If the repaired teeth were ground such that they provided clearance then the pinion wouldn't bind. But there would be serious lash. If the gear set spun slowly it might last a long time. Still, if I absolutely had to do a repair on my tractor's ring and pinion the job would be similar to the one in the video. The difference being that I would not trust grinding the teeth by eye and calling it good. I would first fix the pinion gear by using the ring gear as a gauge and then fix the ring gear by using the pinion gear as a gauge.
I posted those as a joke. Those repairs are bogus. Anyone who knows about manufacturing, metallurgy, precision machining would never accept those welding and grinding techniques as a proper repair.This repair would work. For a while.

it looks like I'll just have to keep hunting for a junk yard or tractor salvage place....I am a proficient welder but I don't think I have the patience to rebuild this thing.It's unfortunate but that repair is not an easy one. I'm a retired machinist, still have my shop, and would only attempt that repair if I had to. The reasons being that the ring and pinion are heat treated, hardened, and then finished on a machine made just for hobbing and/or grinding gears. If I had to make the repair myself I would weld up the broken teeth, rough grind by hand close to the proper profile, and then very carefully grind by hand using bluing to fit the ring and pinion. This would be a very long process. If you can find a place that does gear cutting you should talk to them and see what they think. Maybe try these folks: Replacement Parts They will reverse engineer your gears.

Those Indian/Pakistani videos are unique. Keep in mind that from the 1900's to the 1950's, and even later, vehicles and equipment were made ground up with similar tools and equipment.I posted those as a joke. Those repairs are bogus.
