Burning the bearing off would have heated and expanded the shaft making it harder to get the pulley off.
Yes you are right 👍
Sometimes it’s a wash, with some expansion taking place, but the heat fracturing corrosion on the splines (if any, a straight press can be monstrous.)
Yes and suddenly dashing with cold water will shrink it. May loosen the casement.
We're here for the drama.
A couple of two in rose buds and couple of five gal. buckets of water to quick quinch it , it would drive of easy
This is the first for me I've never seen these guys fail at anything regarding mechanical repair,
We can do that soon
You need several large torches all heating the rim at the same time. This should be done while the shaft is still cold. The expanding rim will open up the hole. Your jacks can be left in place while you heat it up.
Great way to put out this wheel
Considering the mass this pulley had, hitting it with those hammers is like throwing a paper plane at a tire and hoping it will come off
😜😂👍
All those sparks and molten metal it suprises me to see these guys in open toed sandals
You are right here is not many safety’s equipments available in this area
Bare feet would be better. PPE is overrated.
Esta técnica é bem ultrapassada pois deve-se usar calor na hora que tem que usar calor Somente está gastando o gás uma boa lixadeira e um disco 3/4 resolve corte de aço inox a cabeça angular e serve no momento do aquecimento calçar o cabo do britador Aí sim realizar o aquecimento para que isso não desempere o eixo
Thanks for your idea and appreciated 👍
Heat the pulley around the shaft, then put candle or paraffin around the shaft to lubricate it. The heat will melt the candle. And it will suck right in. Friction will be reduced significantly.
Thank you so much for your comment 👍
Bring one scrab handler machines!
Or use few more jack(4or5) with heating more places at the same time (at least 4 places)!
That is what I do..
Or Jack hammer. 👍
Thank you so much for your advice we can try today ❤️
Just a ball park guess, but I'm sure that you should start with at least a 500 ton press. That pulley probably has at least one half thousands per inch of shaft diameter interference, and the sledge hammer's and bottle jack ain't going to do it. But I would love to see you guys with some steel toed Redwings.
Thanks for watching and sharing your thoughts and supporting us
those wheels press on/off...you need a HUGE hydraulic ram
You are right
Pour cold water over the wheel spigot, it will shrink the spigot to allow the wheel to come off.
Thanks for watching and supporting us and for your advice we follow tomorrow
Cut across the inner bearing race with a 7” grinder wheel on two opposite sides, drive a chisel in the cut the brittle race will split releasing the shaft.
Great idea 👍

Fill the pulley with coal and get a nice hot bed of coals around the inside of the pulley like a forge. The heat transfer to the hub from the ring of coals would heat and expand the pulley enough before starting to transfer to the shaft.
Great information thanks for sharing👍
I just can't imagine working in that environment in pajamas, sandals, no hard hats and a high-pitched voice.

That's a hard way to call for a taco bell meal. BONGGGG!!!! Is there a reason why their voices sound like minions?
You have probably gotten it off by now, bit i think i would have tried a few well placed bottle jacks, combo'ed with heating and cooling. Just a thought. Respect that hard work you all do. Looks fun also.oops, now i see you tried that... Lol.
Okay 👍 I will try and shoot the video
I wonder if there is some large pulling device, the same kind they use for pump jack maintenance in the oil field, that would be better suited to remove these parts.
You are right but they never have that kind of device they have only few equipments for open this until now this machine is in same postition from past 4 days
If the fly wheel with that weight and not on level position before removing...it would be very difficult to remove...the forces or wieght acting on one side if the shaft will act as brake...
Great idea 👍
Pulling the wheel off is one thing, but put it back would be another thing.... You all are hard worker men... I respect that...
Thank you so much for your support and advice keep attached with us 👍
@@mimechanics1019 I'm pretty sure that heating the wheel with only one torch will not give you enough heat to expand the wheel. Heat will be transfer to the axle faster than to another side. Consider using of more hydraulic jack. Hope your job done soon...
There is a possibility that there might have been a burr during original installation causing galling in the mating fits. That being the case we should drill and tap appropriate pulling holes in the face of the stuck pulley, with robust allthread and strong back. Have two rosebud heavy duty oxygen/acetylene on standby if needed .Ofcourse get the highest rated pressure hydraulic cylinder available that is compatible with the bolting system and jack against the shaft to break the taper if it is not friction welded, and if that the case and if there is a spare pulley available, then be open sacrificing the pully by relieving the fit without damaging the shaft. Evidently this is a one off deal that rarely happens, been there done that, many good lucks with it.
Thanks for your information sir very appreciated
Is the drive wheel still against the floor,?
The item does not move at all when they are hammering it!
You are right thank you so much for your comment
use stamper machine,vibration can releasing the pulley
Yes we can try tomorrow soon
Hydraulic Jack's between the housing and the pulley.3 to four of them and heating the pulley hub.
Great idea thanks for that 👍
@@mimechanics1019 we had some interesting situations come up with flywheels on natural gas compressors. Similar but not exactly the same. I hope it helps.
Okay sir I will try tomorrow thanks for your advice and appreciate
Don't use heat,, turn it upside down on the crane holding on the end which has to come Off
Great idea thanks for that now I’m trying something like that 👍❤️
M5 grub screw holding it on. Should slide off after removing grub screw.

congratulation grampa
Thank you so much 👍❤️
There is a slide lock, there hammering the wrong way, the lock is tapered like a wedge, the wheel needs to be push in to remove the wedge, , this is visible by the top pully
Eagle eye incredible idea thanks for that 👍
Does it have a circle key lock at the end of pully.Key way or something. Seem badly stuck. should the hydraulic jack will pushed it go.
Yes inside this pully a 2 by 8 inch long Keyway witch is stuck badly we are trying hard but results never come out
@@mimechanics1019 why dont make a thread on the key way, put a suitable size threaded bolt and pull it using a hydraulic puller.Just an idea! maybe the problem already settle 😀

I will be doing exactly the same job next week but on a jaw crusher that only the flywheels weigh 8 long tons each. i use a 100 ton jack on the outside of the flywheel and push against the axle. you have to make a beam attached to the flywheel that the jack pushes on. The crusher is a Morgårdshammar AR 180
Thanks for sharing your information stay with us 👍❤️
@@mimechanics1019 Hello again. If there are threaded holes in the flywheel closest to the axle, in that case use threaded rods to hold the beam and use as many smaller jacks as you can fit. I am aware that not everyone has access to such powerful tools as I do.
Use many Car Jack between the pully ad the body of the Machine. If jacks won't extend far enough use blocks. heat the pullys and cool the shaft.
Great way to open its but we already try it but that couldn’t work because this machine we trying to open after 5 years of manufacturing its very hard but I appreciate your idea thanks for your support and keep attached with us
On a scale this large, i would have suggested drilling the shaft center out, allowing the outer cylindrical wall to "taper", if possible. Then building a even burning fire under the "flat" pully, while packing the bearing race surface with ice. Yes all night if necessary. I've done this alone on a MUCH smaller scale. Weaken the shaft, chill the shaft, heat the pully, and possibly the weight of the pully will allow it to fall off. Then weld the hollow shaft solid again and clean up the outer surface.
Great information that you given to me thank you so much for your support and advice appreciated👍
Manufacture a hydraulic puller.
Nice idea 💡

Not very agree but a little bit you are right because here is not working safety’s thanks for your support 👍
2 hydraulic jack min 100t each setup in line,when you set up jack,titne jack properly and heat then pore the water,have to openet garanty
Thanks for your idea and appreciate you doing this help 👍
First find out how the flywheel is fitted to the shaft. Is it a tapered or straight fit? Is there a keyway? What about locking pins or bolts hidden under the paint. For a sharft of this size at least 200t will be needed to pull the flywheel of. Using a single hydraulic jack can bend the shaft, that's bullshit. So heat the flywheel hub to about 200°C and use several jacks evenly spaced around the hub and pump at the same time.
Great idea thanks for sharing this with us and appreciated stay attached with us
...creo que al extraer el rodamiento, el eje se ajustó aún más en su alojamiento...por ahí si logran refrigerar el eje con CO2 podría pensar que por ese frío se contraerá el eje y podría extraerse...es una idea, refrigerar solo lo que sea eje...
Great idea for this type of work thanks for watching and supporting us keep attached with us 👍❤️
Four 5 tone hydraulic jacks are are about 50euros each in my country. If that bearing was good, you destroyed about 3000eu (meaby more) bearing... You should try with more jacks simultaneusly( its 20 tons togeather+ weight of The wheel), with heating The shaft, then quickly coolimg it with air compressor or water. Heating the wheel also makes The hole smaller...
Great idea thanks for sharing with us 👍
Clean shaft properly, if it has gib head keys remove them [you might have to weld a slide hammer on them]. make a puller out of 100x40mm 2 off to go the width of two holes of the pulley/flywheel , cut another piece of 75x75 x125mm long drill and cut thread to match the 50mm dia 1.5 -2mm pitch thread you will cut on some high tensile 50mm x400mm round bar.You will also have to make clamping bolts and washers. use antiseize on the screw.
Put a lot of pressure on the screw if it does not budge heat it with a number of torches .
Extremely well done 👍 thank you for your help stay safe and healthy always keep attached with us ❤️
How many hours/years of operation until those jaw crushers eccentric shafts are worn out beyond repair.
This machine repair after 5 years
@@mimechanics1019 If these guys can get some liquid nitrogen, they might be able to freeze the shaft to extract it.
Maybe wedges. Two opposite wedges pushing against each other. Like how to remove a Jacobs chuck
Great idea thanks for that
stronger hang chain(avoid falling) and suspended bigger hummer weight, these small hummers are insufficient for such heavy disk.
Yes 👍 you are right we are trying tomorrow thanks for your support and idea💡
@@mimechanics1019 There is another tip: suspend it on opposite pulley chains horizontally, get it stretched and use big jackhammers
Wow you are amazing thank you so much for your help I think now we can do like it ❤️👍👍👍
Could try packing the shaft with lots of dry ice , provided they could get it
Nice advice thanks for your comment 👍
A large wedge with a slot in the middle for the shaft. BIG wedge.

I dont think OSHA would approve that working environment. I mean, hot. Molten metal and open toe sandals? Hand how does the dude with the torch see anything anymore without goggles or a helmet? I know he's not welding, but looking at that flame for a couple minutes and you're seeing spots for the rest of the day!
Yes sir you are right but it’s need owner buy for us safety equipments
Put it in a press ..... it'll pop right off.
Here is not a big press like that who pull it out 👍
Lift the wheel of the ground
Ok sir
...waiting today video!
I have a great video but I want to upload after monitize my channel
To much weight on one edge of shive. Get it blocked up off the ground.
Nice idea thanks for that stay attached with us 👍
They know exactly what to do, they only want yours comments to raise there CZcams points!
Not really
Never give up. You got it! Just a little more extension on dem jacks.
Thank you so much for your support and idea we are trying best 👍
Poor cutting tip. Looks like it's clogged.
Yes it’s opening after 5 years👍
More hydraulic jack. ..
Thank you so much
1)Make sure that no any lock nut or lock bolt around the front shaft. 2)more ton forcing pressure( predict at least 200 ton ) force it need,due to that shaft diameter...sit properly the jack for equal apply pressure 3) apply asid throught the inside shaft if possible? 4) build a super big size electric hydraulic pully puller if you can. czcams.com/video/mUPCZE96Zg8/video.html 5) either u heat up the pully or place it under hot sun n measure the pully temperature for metal expansion Ontop is something can try... key is use tool to fight metal..not human to fight metal...
So with super pressure..either u hear a POP sound (acoustic emission) pull out the pully or broke the pully
Okay 👍 I will check
"Aziz, light!"
Who’s aziz light
@@mimechanics1019 watch the movie The Fifth Element -1997. Aziz grows up and becomes a heavy equipment mechanic!
You know it would have been so much easier if you would have picked it up by the wheel you were trying to pull off.
Thank you so much for your advice we are trying tomorrow 👍
2 or 3 20 ton jacks to separate the counter weight might have worked if they didn't hammer it off center so badly
Thanks for your idea and thanks for your support wish you live longer 👍❤️
An excavator might be able to apply enough to force the pulley off.
Excavator is very risky
no the bottle jacks are more powerful that an excavator.
Working with no safety foot wear , clothing, gloves, eye wear , hard tops , ear protection or masks . Ridiculous…
I'm on the fence with this one. Sure if you're using an abrasive disc to cut or grind and you have sparks flying towards your face, wear at least goggles or a visor. If it's loud wear ear protection. Simple. Gloves hmmm, limited dexterity unable to tell how hot something is until it's too late, getting caught in a drill or worse a lathe. I'd rather lose a finger tip than my whole hand or arm. I guess it also depends on the operator.
You need some Kroil , the oil that creeps , it will move then
Nice idea thanks for that 👍
BHAI NUMBER KA VIDEO BNA DIYE PLEASE BHAI AAP MAISSEGE KRO
Oni belive even Ness can't be over stressed.
Did you try some WD-40 ?
Not now but it’s a great idea 👍 now we try it today
Everything is wrong. No safety. Tiny chain holding up many tons. Hammers 1/500th the mass of the parts. Mismanagement of the cutting torch. 150 year old jacks with the illest fitting levers ever. It takes more than earnest willpower to get things done.
Agree with you 💯
5:57 апчхи! 6:05 ААААПЧХЕЕЕ!!
i was thinking , they need a hydraulic jack and yeah they're listening , ohh still failed to open , i think maybe need one more for both side , ehh ehh they listening me , mmm still can't open it , then i'm think , hell yeaaahhh they just need a WD40 , hmmm they just walk away for biggest failure 🤭
We already try WD40 and acid also
it sounds like "hell´s bells"

Very simple to take off
Yes but how

Странно, что до сих пор никто не предложил ВДшкой попшикать...
Я бы попробовал прогреть ось по обе стороны колеса, при чём сильно, градусов до 300, потом дать остыть и снова попытаться выбить колесо. Нагревание что даст? - при нагревании оси она займёт максимально плотное положение внутри колеса, т.е. как бы выровняется внутри колеса, т.е. натяг оси и колеса станет равномерным по всей поверхности касания. И тогда колесо можно будет попытаться даже не выбить, а выпрессовать. Это немного похоже на процесс нормализации стали.
Greatest idea brother we will use in workshop know all you’re doing well for us thanks for the tricky knowledge love you brother 👍👍👍
Ты размеры этой оси видел? Предложи способ прогреть такое. Чем и как? Если только опупительный костёр под колёсиком не развести...
@@endprg6477 Видел, и даже, сравнивая диаметр домкрата с диаметром оси, визуально могу оценить его величину, что и предлагаю сделать тебе. Чем? - автогеном минут 5-10 с каждой стороны. Зачем опупительный костёр под каждым колёсиком разводить - хз, ведь задача стоит не впустую железо греть, а исключительно прослабить соединение после остывание из-за такого вот искусственного, если так можно выразиться, перенатяга. Плюс к этому: искусственный натяг позволит раскрошить грязь, пыль, ржавчину, остатки краски, т.е. те частицы, которые усиливают абразивное трение между осью и колёсиком...
Has he run out of oxygen 🤔
Who’s?
@@mimechanics1019 The guy cutting the bearing...too much gas and not enough oxygen 🙄

@@mimechanics1019 not jacks big hydraulic press 🤔
Oh yes 👍 well we are try it tomorrow

I wish they had work boots
Only safety equipment
Please give the contact number of this manufacturer
Mobile Number chahiy in ka ?
I don't know about you, but we say "take the bigger hammer".
How much bigger and weight?
Expanding the metal with heat isn't going to help you. Its going to bind up at that angle also. You need to suspend this off the ground and then use the weight of the bottom pulley along with sledge hammer.
Nice idea thanks for that 👍
no how do you hammer the pulley then if you flip it over. the weight of the machine is not very much compared to the jacks. they are at least 20 ton each maybe 30 ton each. the machine weighs maybe 10 ton.
do it later
Yes we done this work
Os três são cabeça de ovo kkkkkkkkkk
He's hitting it when it's on the ground at the start... Are they really that stupid?
Don’t call stupid please keep supporting us 💕👍
They lived happily ever after, and died on the same day ... (c) There will be no second series - when the wheel was removed, the alignment of the unit was sharply disturbed, the hoist could not stand it and the operator was crushed to death.
Not sure but a little bit you are right but they have to work for own familys not have another way to get money easily here
Very stupid people ,before torching the bearing you first remove the pully . That you do heating the pully from below . Between the houding and the pully more than 1 jack (best to use 3) ore use double wedges wich forse upposit with 2 hamers at the same time .......keep cooling the axel ! I used this technic lots of times and never failed ! Still 1 thing tey use not enough oxigen wile torching !
Great technique for learning thanks for it👍
