First world differential repairer for 12 years here. More than a 1000 diffs rebuilt in my career. Very few people in the world with my experience that’s for sure, maybe none. I can gospel about this. If it even rotates in place I say it will explode into pieces within a mile. Must be carbon rehardened. Nevermind the noise and the fact that he ruined the other good teeth at 8m20s...

Good welding skills though! Other than that they are completely clueless about the super tight tolerances such gearings have to work with. That why they tried to “repair” it. I guess it’s just a learning experience for the shop or just a KZfaq visualization trigger.

MY thoughts exactly.These guys do great body and frame work,but this is much more critical. While this repair may get INDIANA JONES TRUCK across the rope bridge,it most likely won't last.If he had a 5 way CNC and carbide cutters and the ability to program it correctly,then maybe.There's a reason gears like that have a polished precise surface and use high pressure lube. It is the ability of the lube to allow the parts to slide past each other while transferring the pressure of movement across ALL of the tooth SURFACE{or contact patch in the case of gearing}. But at least this allows them to make one more delivery of goods or product,so my hats off to them,never give up!!!!This channel is an inspiration to others,anything is possible.

It better than before and you got to give it to him, you cant tell which tooth got welded!! 😁

I think they know it won't last. But it's either that or paying 100 times more for a new part. Maybe they will need to fix it again another 10 times until the truck need to be totalled. That is still significant money saved. The money saved could probably feed his family for few months or even years. In terms of safety, well I guess they are willing to take the risk. I guess it's not easy to understand when you are living in totally different quality of life.

All I've got to say is a weld is stronger than the original material. The rest of that entire tooth will have to sheer off before that weld breaks. That's just my life experience and also what they teach you in welding school

You guys have been living in the first world to long. Give them credit for attempting a repair.

That's an amazing story. If it worked until your part arrived then it worked! As someone living in Indonesia for the last ten years I know how long it takes for parts to arrive from America! It's right when you say I guess it got lost that it shows up 😂

I think the welding rod he showed is a high in nickel rod, one that’s made for “wearing in” . I used rod with high nickel content to repair a track system for an assembly line. I had to weld flush enough and not to grind because it would wear it’s self to shape. I’m wondering if he’s trying to do kind of the same thing but with this gear. That explains why he can get away with a grinder, but then again how hard is the ring gear that will either drive it or be driven by

This is why no mechanic repairs these. For as much work as they are doing only to have a finished part that has questionable strength wouldn't it have been just as easy to get a new part?

@@Buddy-po4hv quality control

Wouldn't be surprised if this part doesn't last all that long. I also thought the title was a bit moronic, of course a _mechanic_ wouldn't do a machinist's job, the most a mechanic would do is replace the part, and an actual machinist would properly make the part. Not to mention pinions and ring gears are fairly easy to get, it's not like this is some hard to find part that requires a one-off machining job. I honestly wouldn't even be surprised if this is a random piece of scrap used for the sole purpose of making content, like all of those low-quality 'DIY project' channels that make nothing of practical use with random objects they find lying around. Also the reply about me being so well versed about spare part availability in poorer areas of the world is hilarious. People quite obviously don't understand how easy it is to salvage parts off of another inoperable vehicle, especially when the part in question is as abundant as a differential. If it doesn't fit, adapt it; doing this would be a better job, a faster job, a cheaper job, and a safer job than what this video shows. Cuba's car culture, which is a very well documented situation of lack of available new parts, can teach you a thing or two about this. Some of you actual idiots should go educate yourselves, though I wouldn't expect much from people that lack common sense.

I wonder how this would work with hardfacing rod.

@@mrmikemanify the hardface welded portion will be hard but perhaps the weld heat will reduce hardness of adjoining un welded portion unless his welding technique as it appeared to be in small bursts didn't heat up the adjoining portions too much .

They don't have the option to just buy a new one. That would come from somewhere like Germany for example. Do you think they can afford that? Its just not an option. This is probably the only real logical option. Its still steel, hardened or not. It will hold up for some time. Some gears are only induction hardened on the teeth, which could also be potentially incorporated into the repair process in future. The tooth looks like it broke because it was brittle to begin with, which isn't going to helped by hardening? Perhaps it will last longer this time? I doubt the machine has enough power to shear apart unhardened steel. Steel is incredibly strong. Perhaps the small weld blobs cool in the air and adjacent steel fast enough to slightly harden the steel? @Michael: I doubt enough heat will make it into the other cogs before its dissipated by the center shaft... I doubt this is the first one he's done. Probably means they work well enough to bother. Gears are even repaired by welding in the west. uwp.ca/en/gears/ All the best to all Volk; from New Zealand :)

I work at ZF Friedrichshafen and I have to tell you that the teeth for gears or differentials are not inductive but nitrated or case-hardened! This means that the surface of the material is very hard and wear-resistant and the "core" of the material is still "soft" so that the teeth do not break directly when the load changes. And it's like cams and crankshafts, the surface has to be hard and the core soft. Of course, when the parts are well welded, the teeth don't just break, the surface isn‘t hard. It is clear to me that this is how repairs are made in many parts of the world and the workshops help each other as they can despite everything good work
