Hitachi EX5600-7 ultra-large hydraulic backhoe excavator has an acces door, maybe your excavator has a tiny one too. Send in your smallest employee he can weld from the inside for extra strenght. Have a nice weekend 😊
The first hub that was difficult to remove. If u heat the hub directly over the keyway. It will come off much easier. So heat the entire hub, then while trying to remove focus the heat at the keyway. 20 years+ experience in heavy equipment.
when you put that yellow coupling back on heat it up to about 300 degree and then it will have expanded by 0.00000654 inches per degree. Calculate .00000654 times 6 inches times 200 degrees hotter than workshop temp = .007 or seven thousands expansion. If workshop is 70 degrees then heating the coupling to 400 degrees would make its bore expand by 11 thou and it would just slide on.
Охренеть, сварщик 😅😅😅без маски,в очках варит ...😊шо будет с его рожей, кожей,глазами??я сам сварщик с 30ти летним стажем работы в теплосети.да ,охренеть ты мужик себя ненавидиш.
I think the gearbox is a copy of a Fuller-Traylor unit. I am actually watching this as prep in-case we have to rebuild ours... If you are using units like this, make sure the oil is THICK. Don't try using low viscosity oil or you'll be getting some new and exciting growls from it.
A few days ago, we copied a cast-iron welding procedure from one of these videos (pile of burning charcoal, borax, gas-welding with cast-iron filler material). Worked great despite us not being able to find the safety sandals or robes for the job. We also deviated from procedure by using a dead wheel-barrow shell as the basis for the furnace.
Oh you're "that guy" Maybe you can upload your videos to your channel so all the experts can leave their opinions about your work. I hope you cheer up and life gets better for you soon ⛳
Just a bit of grease on one end of the rollers. Grease is expensive. It will not be re-greased until it seizes up again. Even the silicone sealant, they only put a bit near the center. The gears do not seem lubricated very much. They did not clean the mating surfaces of the two halves before bolting them together and machining, there is dirt in between them. The shop is a mess. Junk everywhere on the floor. A mountain of chips sitting in the middle.
Easy to be a critic but this job was difficult.Well done overcoming the challenges but the floor should be kept clear before an accident happens,we’ll done workers….
There is a reason to use a proper sized key-way instead of a bolt. It helps keep things aligned under load so as not to cause the damage these guys have just spend days fixing.
И что же у него по пизде пошло? Отверстия не разбиты! Подшипники на месте! А вы промахнулись с посадочным под подшипник. Ну бывает и такое.он бы еще поработал. У вас ремонт ради контента.
подшипник провернуло в корпусе, размер ушел. А подшипник заклинило от нагрева, тк там нет смазки. Отверстия под централизованную смазку заткнуты. Слесарь рукой набивал пластичную смазку, которую нужно было прокачивать пресс маслёнкой! ua-cam.com/video/5J8n-G6ooPU/v-deo.html Да слесаря сами угорают с того что они делают : ua-cam.com/video/5J8n-G6ooPU/v-deo.html , ua-cam.com/video/5J8n-G6ooPU/v-deo.html Это похоже редуктор для своего предприятия, начальство сказало - нужно срочно, "сделать нужно было на вчера" А редуктор уже видавший не один ремонт, походу его постоянно клинит. Выходной хвостовик вал-шестерни видно уже обрывало, полумуфта после ремонта со следами РДС видимо шпонку часто срезает
Собирали на холодную а разбирают на горячую с помощью кувалдьі и еще какой--то русской матери Что нельзя постелить какой--то брезент или доски При такой стерильности работать будет недолго

Maravilhoso trabalho e dedicação desses profissionais, todos eles, mas me admiro com o torneiro mecânico.

Amazing craftmanship!
😊😊top workers, perfect, prima !!! 😅😅😅
Thank you 🙏 still new for me GEMS but great 👍 job 👏👏👏👍🎥☮️
Love that brooms even get the custom, Indian paint job.
It took every man in the village to get that coupling off!
The lathe in the second part looks like a well-kept machine.
Восхитительно .
Boy the hub was sure seized in there. Nice job guys
Why didn’t you clean the join area before resurfacing the holes. Nice the diameter is oval because of all the crap that was in the join.
round is extra
So that it will come back again soon 😂
At least they keep the shop clean inside and out
Bravo majstori!🇸🇮♥️♥️♥️👍👏💪
Veliki pozdrav iz Slovenije!
Nice work

facing that metal with a three-jaw was fire
Trabalho magnífico parabéns
Спасибо❤❤❤❤
Impressive thread cutting
Nice job guys.
Congratulations
The guys perform miracles to the best of their abilities, but in industrialized countries such work is called "wiping your ass with glass"
12:43 professional lifting.....OMG!
Asia... Who cares...
Hier mag je wel trots op zijn, Groet uit Holland.
That guy with the sack is very brave!
😮 excelente
I used to make the parts to go in these gearboxes - shaft grinding case drilling, etc.
when you put that yellow coupling back on heat it up to about 300 degree and then it will have expanded by 0.00000654 inches per degree.
Calculate .00000654 times 6 inches times 200 degrees hotter than workshop temp = .007 or seven thousands expansion.

@@paulapalooza8655 you are sick. seek help.
A estos muchachos les tiras una nave espacial y la sacan andando 👍

There goes the Hitachi warranty 😄 It would help to grind a bit of the paint off before welding.

1:03:50 shoe on fire, pause.
It’s like watching a horror movie
Why aren’t your people wearing safety boots?
They do wear safety flip-flops.
A few days ago, we copied a cast-iron welding procedure from one of these videos (pile of burning charcoal, borax, gas-welding with cast-iron filler material). Worked great despite us not being able to find the safety sandals or robes for the job. We also deviated from procedure by using a dead wheel-barrow shell as the basis for the furnace.
They have steel toe capped sandals
You forgot the jetway on assembly.
Apparently the quick-change tool post has yet to be introduced to Pakistan
😊 🤙🤙🤙🤙 🙏🏽🙏🏽
Why didn’t you grease the bearings prior to assembly.
Not impressed with the quality of assembly or maintenance.
Your shop is dirty and unsafe.

No surface prep not even a degrease. Straight over he top oof impur? Bodge job right there
Now I'm older, my back can not take being stooped over for long periods like many of them.
Gearbox needs better lubrication system.
Guy with big-belly, burning hands off, then is allowed to use cold water on them, aaaaahhhhh.
Easy to be a critic but this job was difficult.Well done overcoming the challenges but the floor should be kept clear before an accident happens,we’ll done workers….
Would engineers not do better to fit replaceable bearing shells--like automitive main bearings?
no big deal. I'm 78 and worked maintenance in papermills and rebuilt many gearboxes and ran lathes that were very old
Да, мороки много было.
el proceso de soldadura de la extensión de la pluma de la excavadora esta mal ejecutada
شكرغ
Urge un buen soldador.

The loafers…
Был Хитачи, стал Xуeтачи.
Why don’t you clean up the floor? It would be so much safer to work. Get the apprentices to take turns sweeping.
It’s so unprofessional looking.
Its a poor workshop, on an underdevelopped country.
This are smart , efforted guys! My respects❤❤❤😊

They either weld with no mask or have to hold it on by hand damn get a real shield.
Whatever machine that booms going on will be severely overloaded.
Just like all their trucks

Любимый ключ у них - разводной . Плохо им работать
Looking working not as teckinition, not using knoledge.
Why would you not use a welding mask. Arc eye is no fun.
Do not work with lathe wearing gloves
Look´s like massproduktion in Germany in 2029 ,
but wait,
there is no electric power any more🤣🤣🤣🤣🤣🤣🤣🤣
всё примитив ни какой электроники а как работают ребята молодцы привет из РОССИИ
Bravo! Pozdrav iz Slovenije 🇸🇮♥️♥️♥️👍👏💪
Menyedihkan, tidak ada safety shoes, sarung tangan, helm, pakaian kerja, seperti perbudakan.
Собирали на холодную а разбирают на горячую с помощью кувалдьі и еще какой--то русской матери Что нельзя постелить какой--то брезент или доски При такой стерильности работать будет недолго
сначала всю смену епались с распрессовкой, потом кто-то подтащил домкрат и дело пошло быстрее
👏👏👌👌🪛🪛🔧🔧
