Looks like it was previously repaired. Badly. These poor folks must rely on repairs because replacements are so costly, if they can even be sourced at all. This man does a pretty good job. Definitely better that the 'last guy'!
Lotsa doubters here and they may be right that this fix won’t last but this machinist has obviously done it before so perhaps he knows something you “experts” don’t. In any event, a “temporary” fix may be just what the trucker needs.
If 2 inches of cast steel was not strong enough a 1 inch hammered in plug and a thin ring of weld is not going to be stronger. That will break at the first missed gear or quite likely at the first slight incline.
O'CONTRARE.. mon Fraire .. That was case hardened steel and the weld was deep using -18 weld rod.. nasty fix as the fixing machined pin probably should have had a small hole drilled through it and heat pressed with solder at the bottom of the hole, but this 'ain't the first rodeo' for this old machinist and that tractor is old and will last another 40 years with that fix.. This is not a high 'horse-power' endeavor, more like 223-250Hp /200Kw and 60-80 Kilometers per hour max.. but probably German made.. from the '60s at best. Note the new tyres... Not only that, the break was rusted, indicated that it was a long time coming.. and the fix was on the road, relatively cheap.. most of all, timely.
@@tsclly2377 Fair enough but that is even more reason for it to fail if solid case hardened steel (could not cope then no amount of less that solid case hardened steel (although I did not see any evidence of surface hardening so probably just through hardened (tool steel was able to cut the outer surface just as easily as the middle) will also fail. Is any weld (let alone a stick weld) going to be stronger than solid case hardened steel? Is any threaded connection stronger than a solid connection (cast or forged)
Em África, vi muitos "reparos" desse tipo feitos em viaturas militares. As peças originais quebravam, mas não me lembro de peças reparadas que tivessem problemas
this is one of the less convincing videos of this type. however, the result may turn out well. as far a comment about welding here, i am certainly told that a correct weld is stronger than the original metal many times. it is all an art ...
How is not all the machinist and welders not blind in Pakistan from welding without a welding helmet, only a small shield with a dark glass mounted in it, when they use anything at all !!!!!!!!!!!
The pinion isn't broken, it was a piece of junk that was cut with a torch. You can see the bluing on the pinion shaft and the torch mark at 3:50. The repair will never hold against the torque. clickbait.
freeze the male part and it will shrink in OD by .001". Heat the female part with a torch and it will expand in ID by .003"+. This lets you easily hammer (better yet, hydraulic jack press) the male part into the female part. When the temps normalize, the parts will be frozen together.
Not an internal or external micrometre or DTI in sight, if you performed any type of welding on a lathe in any engineering works you'd be sacked on the spot. This will be at most 2/3's as strong as the original that sheared so this will last for year's just as long as you don't put any more than 2 tons of load on the truck this came off, if it doesn't shear off with a load of 40 tons (the average for one of their trucks) l'm a Giraffe.
this really breaks the bottom of the barrel. when you don't even have an air compressor to clean the parts from chips.... instead you just firmely blow on it.... good lord. If basic tools are a major purchase, than sorry but I have no trust in the quality of your work.

I don't have much confidence in this repair , I could be wrong but I wouldn't want to depend on it, can't you not buy a replacement ring and pinion gear there?!!!

I would really like to know how long that repair lasted.
Stop overloading your trucks!
There is no oil at all on the broken part. And the broken parts are produced from behind a tyre out of camera sight.
Not much life left in that large drill
You would have to be dead in the head to believe these shows😂😂😂😂
Did it break right where it was fixed before?
It starts off bad and just gets worse. They work with what they have, but really?
I’d give that repair about 200 miles….or one good sized hill
200 miles i giv it 200 feet max
anyone notice when he threw the pinion gear our from under the truck that it didnt have any oil on it?
I love his parting tool😂
You'd need a stopwatch, to see how long it lasts

Notice it's been welded before, but thanks for your "EDUCATED" opinion of us who are 'EXPERTS".
Love their safety sandals. Steel toes?
No toes 😅

Seems rather sketchy to me.
Hauling a 100,000 lbs doesn't help either.

Seria muy interesante ver alguien que lleve estas piezas "reparadas" y las compare con originales en un laboratorio de resistencia!

never strike finish-machined part with a steel hammer. If you do, you'll distort the part.
Сомнительный ремонт,тем более ресурс этого узла,гарантия до ворот. Судя по тому сколько они грузят в машину,надеяться на чудо не стоило бы

Hola el responsable es el conductor por la falta de pericia pero para los del taller que mejor que sigan muchos mas como ellos,

Hola los" dientes" de la espiga ya tambien estan dañados lo mas recomendable sera una nueva,poque haci no se puede garantizar un resultado seguro
freeze the male part and it will shrink in OD by .001". Heat the female part with a torch and it will expand in ID by .003"+. This lets you easily hammer (better yet, hydraulic jack press) the male part into the female part. When the temps normalize, the parts will be frozen together.
If they could machine and measure, a .001 interference fit is all that is needed.

watching this was quite a sacrifice of my brain. so after 2 minutes I stopped watching.
Jumper cables on the pole outside?
Boss!
I doubt that opinion gear came out of that truck,splines too dang rusty
this really breaks the bottom of the barrel. when you don't even have an air compressor to clean the parts from chips.... instead you just firmely blow on it.... good lord. If basic tools are a major purchase, than sorry but I have no trust in the quality of your work.
Nice work ..... Pakistani wow Mechanics
you think they would sweep the floors occasionally, the build up of dirt is disgusting. you can eat off of our workshop floors
Amazing workmanship by some truly skilled mechanics. Primitive does not necessarily mean inferior. These guys proved it. Good job from California USA

As usual, no safety glasses. Did anyone notice how filthy the streets were? Life expectancy must be 40 years.
Nem világos, hogy miért lenne a csapolás "lehetetlen új módszer" még akkor is, ha menetes. Egyébként a fószer egy pillanatig sem foglalkozott a tengely hosszával......
.
Did I actually see the splined part crack when he hammered that plug into place?? Yeah, I'd trust that part........NOT!
I saw it too!. .....Eeeek!
Just stop uploading videos....
Brilliant bit of engineering, these guys could repair anything
Good machinist, terrible welder. No set up for the weld at all. Still voids inside.
This gentleman is a magician. Bravo!

Nice
A very professional job
この方は旋盤の使い方イマイチですね😢
You can use the equipment that you have this is 3rd world country
I don't have much confidence in this repair , I could be wrong but I wouldn't want to depend on it, can't you not buy a replacement ring and pinion gear there?!!!
i would not let such guys WASH my equipment, much less 'repair" anything.
