Over the years of living out in the sticks, I have made a few sketchy repairs in order to keep moving ahead instead of being dead in the water. Many of them were re-done more correctly and with proper parts a.s.a.p., others worked fine for years. A very experienced mechanic I sought advice from when I was young gave me a range of options for repair of an engine. Of the most expedient and inexpensive, he said "It's a poor way to do it, but poor people have poor ways!". I chose that way of doing it so as not to get any poorer any faster and as far as I know, that engine is still running. It's amazing to watch these guys making field expedient repairs with limited resources. My hat is off to them. Not only do they keep rolling ahead, they provide endless opportunities for the countless armchair experts who like to criticize their work.

Yet again hats off to the skill but one just cannot expect a gear filled with weld and finished using an angle grinder to last. Such gears are machined, hardened and then finish ground using very accurate machines. I would love to see the wear pattern after a few months. The caption says "I repaired the pinion that no mechanic repairs" well, there is a very good reason why nobody repairs them.

[@jaymoney119966]

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

[@erronellington8800]

It is a good repair to get you out of a bind but it will not last. In my early years as a mechanic living in Jamaica, I had this done at a machine shop called Ramdial Engineering in Kingston. Those guys requested the crown and pinion to be present for the repair. It was done to the pinion gear in a chevrolet D20 diff and lasted about 4 months then we had to do it again. The second time we did the crown and pinion which lasted another 4 months. The parts had to come from America and were very expensive at the time and took about 4 months to come into the island. The repairs really bought us some time. I highy recommend this repair but keep in mind it is only temporary.

[@nevinkuser9892]

Agreed, good work restoring that part to get back running. Longevity, as others have said, is the issue. The part might look good, restored and polished up, but how well it meshes, in terms of the pressure points on the gear teeth is another matter. To see it installed, and Prussian blued up to show contact pattern would be nice, then the repair could be judged a bit more accurately. Regardless, hats off to these sandaled mechanical madmen! Loved him polishing the bearing mounting surface with his finger just about resting on the tool bit! Cowboys!

[@robertoruiz7069]

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.

[@mawe42]

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

[@unkertech]

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.

[@aaronsimpson8329]

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

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.

Hint: making it look good does not mean it will work good. Welding and grinding make all kinds of internal stresses and adds impurities and alloy discontinuities. It might be okay under light loads for a short time. But it’s definitely worse than the original, and remember, THAT failed. Also it’s nearly impossible to regrind it to the original spec, as the dimensions are very hard to measure. So the gear contact areas will be wildly different even if the surface is only a few thousandths off.

There's a really good reason why people who understand the nature of these parts don't attempt to repair them. This "repair" is useless as it will eventually ruin both the ring gear and this pinion because there's no way he can equal the accuracy of the CNC that cut this. Not only that but for whatever reason he ground on *all* the teeth, basically ruining the accuracy of all of it. It'll probably last a little while but it'll be noisy as hell (which they probably don't care about) and will fill the entire differential with metal shavings as it grinds itself down, thereby ruining all the bearings along with it. With the loads they put on these trucks, I don't give it long. These guys are pretty handy with what they have to work with but, again, this is not a repair.

There is a reason why it's called precision spiral bevel pinion gear. It's not something that can be repaired with a stick welder and angle grinder. Here are the reasons why "the scrub pinion which no mechanic repairs" and how you can at least try: 1. Prep work. None has been done. Part came from the truck and it's impregnated with oil. It needs to be burned off or cavities will form in the weld. Also you need to remove some of the remaining material to cut out micro cracks. The best way was to gauge out or grind out some metal. 2. Hardness. The part was not aneiled before work and hardened after. The boundary between weld and the part will easily open up when load is applied. 3. Prescision. Bevel spiral was restored by eye. No templates were made or not shown. Wandering contact point between two gears will create high impulse forces and will start damaging the main pinion and bearings. At the very least some ink could have been used to try to mesh this spiral pinion with the main one by grinding and scraping. 4. LOAD. It's very highly loaded part. Those are forged before machinig and that's why they splinter. Under high load the welded material will start to "flow" closing the gap between teeth. So in the end we have a "new" shiny part which is only good enough for the dumpster or to get to a local service where it can be replaced with a proper one. Even a highly worn one is better then this. No one in their right mind should attempt to drive a loaded truck with that inside. But what do i know, this comment will get less likes than "Good job", "This is what they have to do to get by" and "They need to feed family. Shit repairs like this can kill people.

Yes, you can make it look like new - but you cannot make is good as new. Huge difference. Considering the load that the gear handles, the welded metal is not as strong as the parent metal and will fail again. Much sooner than the original part failed. This gear went through a hardening process. What you did is just create a weak and brittle point in the gear. You have a solid grasp of the mechanics, but miss when it comes to the science of it all. Starting and stopping so much without clearing the slag will allow for inclusions. A wire wheel on a grinder would be of significant benefit for you while doing these welds. It would help with the inclusions. And watch out for porosity..... However, still. Sometimes you just have to go forward. This would fail everything in the US, but where you are, it works - for however long.
