Agree with the previous commrnt the first minutes are much too long..... problem demonstrating for dummies. It's a spigot bearing or can be a spigot bush in many cases, supporting the input shaft of the gearbox. The fit can't be a pressfit or you will struggle to dock the gearbox home. A slight slip is OK .
There's no way the shaft needed so much building up, if any at all. The new bearing was canting slightly which is ok as in situ it can't do that. I'd be more concerned now about heating the shaft and obviously running earth thru the lathe bearings (that's what it looked like, forgive me if it wasn't).
he did not repair it. he just made it worse... the heat from welding made the shaft soft. in the future it will snap or broke. at least he could quench it to make it hard again. the barring on the shaft should press on that and should not go in to place by hand freely. he made the shaft too small for the barring.
That is so true my brother that is so true they should’ve gotten an insert like a bearing of that size and cut it down to size to fit the bearing but instead they had a heat and destroyed it for the future and it’s going to fail miserably God bless you brother ✝️✝️✝️
@@ГошаВеликолепный-ь1ч в его случае уж лучше легкопрессовая. Наплавка мягкая, подшипник её раскатает. Да и вообще стремно всё это... Сколько там теперь трещин по граничному слою - одному их Аллаху ведомо, и когда эта цапфа оторвется - тоже только он один знает. Я лучше бы втулку на горячую посадил под внутреннее кольцо подшипника.
Why do u guys steal videos off each other? Can’t u find a shop and shoot ur own videos? I’m not surprised that even in India/Pakistan… where scams are huge you guys would scam each other 😂🤣
That is the fastest way to absolutely ruin a lathe. The proper way would be to set up a rotary ground directly on the spindle where it exits the rear of the headstock. Use a couple brass rings with some spring-loaded copper fingers, or carbon brushes. I have seen people rob the commutator and brush setup of an old motor.
Микрометр не лезет, значит надо ещё снять, чего, сколько, куда похрен, внутреннее посадочное какой то хернёй меряют, потом эту херню штангельциркулем измеряют, нет бы сразу штангелем измерить, потом напильником доводят, и как следствие прослабили изнутри, скраю толще! Токаря от бога, не фигли вам!
was ein Pfusch, als nächstes wird der Zapfen abreißen, man hat ja direkt die perfekte Sollbruchstelle mit eingearbeitet, der Lkw wird nicht weit kommen ;-p
Klinger got him a Dial Indicator, looks like it confused him. 🤔 That input shat will be back, welding the end removed the hardness. No matter, they have plenty of welding rod.😝
@@TheFeller1554 Probably a You tuber sent him the mic. Most likely it was in decimal, not metric & that threw him for a loop. One video actually had a dial indicator to check run out...floored me!
18:26 when you can rock the pilot bearing that much on the input shaft, you're shaft size is .005" to .010" small. It should have been a few tenths below the bearing ID. OOPS!!
After that he took about 20 strokes with that big course file! Thats probably another 2 to 4 thou. It's too loose. File it 20 more times, and it should fit perfect.
That’s exactly right that’s what I’ve been saying but some of these people are amazed at this lousy repair job it’s going to fail and fail miserably and caused further damage. God bless you my brother thank you for your input✝️✝️✝️
Always the same crap. welding it, milling it, thats it - but its hardened - and they take that away, because of the heat, will not last long....but, the mechanics are soooooo cheap, that nobody cares ^^
Al final el rodamiento quedó demasiado flojo porque con el torno le quitó mucho material a la pieza. Sería necesario para que quede bien soldar otra vez y volver a quitar material con el torno.
You all making fun of these poor workers. I am sure they at least watched a RU-vid video on how to do this repair... probably saw it on Amazing Technology!
All those guys around the machine and none of them know how to work those tools micrometer and I don’t know the name of all the others but they’re specialized tools for machinist and I know this for a fact I’m not a machinist but they’re not using those tools properly so they have no idea what they’re doing they’re gassy and cutting and cutting until they get it to fit. A true machinist would have the calculations and only do one or two cuts and that’s it but you never weld anything like that especially on a standard transmission the stress alone would disintegrate that within a month, what they should’ve done is found a bearing insert they would fit the shaft after they clean it up and then cut it down to size to make it fit the bearing that would give them double protection and it would work for a lifetime but the way they did it it’s going to work for a short time God bless you my brothers and sisters do you know what I’m talking about these people are not that bright.✝️✝️✝️🇺🇸🇺🇸🇺🇸
These guys are flaming idiots honestly anybody with any common sense would have put in some type of bearing and cut the bearing down to size to fit the other bearing on the shaft. What these guys decided to do is well some more metal and then cut it down to size it will work temporary but the welding will become weak and start to disintegrate within time they are not thinking properly or they’re not engineers to make a long story short I really think they got their experience from trial and error which is the worst one. You have to be trained properly to keep machinery going God bless you my brothers and sisters take care✝️✝️✝️
great machining... but the bearing should be much tighter on the shaft - it should be a press fit and need to be pressed or hammered on. If the bearing is able to rotate or slide on the shaft like this it will cause exactly the kind of wear that you were fixing in the first place!
А зачем показывать проверку индикатором, если потом не последовало никаких оргметодвыводов? Да и вообще, похоже, что индикатор чувак в руках держал впервые...
Redundant first few minutes, BUT then.... That is the best welding videography I've ever seen. I not certain what you're doing different, but it works! As for the repair, that's a different matter.
@@loveofchrist5808 And if you had any reading comprehension you would see I was referring to this channel alone, where the repairs are typically butcher jobs. I have no need for your blessing thank you very much.
@@yarrdayarrdayarrda i’m sorry brother you don’t understand but it’s kind of complicated to explain it has to do a lot with engineering and manufacturing of steel have a great day ✝️✝️✝️
