Repair DAMAGED Hydraulic Cylinder for CAT 651 Scraper | Part 1

844 миӊ. көрүүлөр154

    This video is Part 1 of repairing a damaged hydraulic cylinder for a Caterpillar 651 Scraper wheel tractor. This is the Apron lift cylinder on the machine and has been damaged by something causing massive amounts of scratching inside the barrel and on the piston. In this part 1 video we start with the old cylinder barrel and set up in our lathe for machining out the welds to remove the barrel end and head flange. We use welding on the head flange and heat with flame torch to expand and remove. The head flange needs to be bored out, built up with weld and then machined out to suit the new barrel tube. We then set up the new steel tube in the lathe for machining the outer diameter and boring out the inner diameter to match OEM standard and interference fit for head flange. We then measure and drill in oil port holes into the new barrel and heat up with flame torch ready for interference fitting the head flange.
    In this video we are using:
    - TM-26120G Lathe
    - BM-63VE Milling machine
    - WIA 500i Weldmatic welder

      Hey viewers Happy Easter and thanks for watching todays part 1 video of the damaged 651 apron cylinder! Sorry about the background noise of the rain we had plenty of it for a few days. How's that cliffhanger ending 😅 keep an eye out for Part 2 to see how it ends up! 😎👍 Subscribe and hit the bell icon to turn on notifications so you don't miss our weekly uploads. 👇 🤳 Follow us online here: Instagram Facebook

        @CGT80 thank you so much for your comment. I really appreciated. I hundred percent agree with you and of course thank you for watching :-)

        @Jimmy's Auto Clinic It was well lit, well shot, well explained, and looked straight forward...........then I got to the bloopers and all hell broke loose! As a pro in a number of trades, I can tell you that people who think pros don't ever fuck up or run into problems are wrong. A pro just knows how to fix it or work around it effectively so that the end product is great!

      10 out 10 for both video quality and your machineing skills.

    3. Matthew McCormick

      Dont see many skilled machinists anymore. My grandfather was one and when he passed on my grandmother sold it all off. I wish i had it all. You are a craftsman for sure

      I truly admire your work, never been one for lathes or machining, I am a boilermaker, leave this sort of to the pro's, just love this sort of thing, fascinates me for some reason, keep up the great work Kurtis 😎😎 love the dog, even better was the FUCKUP's at the end, now this is a typical Australian workshop 😂😂😂

    9. Luke Smith

      I work in machining shops and this guy is the guy you wish were your mentor during your apprenticeship. Got a sub from me.

    10. Shawn Strode

      Wow Kurtis can smile.

    11. Jason Hirsch

      Not knowing how any QC is done for this, I take it Xray isn't part of the final checkout ? (Aero work)

    12. Persoana a 3-a

      I still don't know why I'm watching this... I should be working myself, not watching someone else work... LoL. At least someone's getting their work done...


      Great video, I enjoy it. I just wanted to know if it would be cheaper to buy a new cylinder or is that cylinder not available for purchase

      God I love Youtue, you get to learn about all sorts you would never even find about in your daily life. I work in manufacturing but this is not an area I know anything about. Great stuff.

    21. Tony Nameless

      WIsh i had a lathe, even for small parts.

    22. Team Phene

      Why gender specific? You sayin gals don't watch?

    23. OhYeahBabyOhYes

      Would it be a feasible solution to build the inner surface up by spray welding?

    24. liddell157

      what do you guys think this repair cost? vs buying a new cylinder?

    25. Larry Masters: Power Building & Conjugate Training

      How did you acquire so much knowledge about all these mnachines? How can I begin to work at a shop lik yours when I graduate welding school in January 2022? You never seem to have a boring day! Cheers from Detroit!

    26. Onisivoro Qio

      You've got me Hooked Mate,great Skill Level and Resourceful in your Work.I've Subscribed now.

    27. Frank Bullitt

      Very clever work. What does a repair like that cost ?

    28. FriPilot

      You got the 'Oh Fuck's down perfectly! I'm proud of you.

    29. Sean Cummings

      Hey Kurtis could you possibly go into more detail on the alignment portion occasionally on your videos? I have some minor experience on lathes and I know how critical the process is. I'm just amazed at how well you can align these giant pieces of hardware. Otherwise I love the videos! I'm fascinated by both heavy equipment and machining processes!

    31. glowdusty

      i am gonna say this is amazing work cx

    32. Robert Jones

      Hey guys, I used to do this exact same type of repairs when I first started machining in 1981 (Fuck (!) I'm old.). 40 years in. At first, it was very, very intimidating, but after doing a bunch of them, "Piece O'Cake". I really enjoyed that video. What isn't quite so enjoyable, is standing up on top of one of those paddle scrapers, putting a custom made portable boring bar and fixing that pivot that wears out between the front half and rear half of the machine. Standing in maybe 3 or 4 inches if hydraulic oil in that valley up there. It's been a while, thanks for the memories.

    33. Vlad Kudasov

    39. Baron Clime

      What is that contraption in the shot of the rain that has a crane boom and a clam bucket (looked like)?

    40. Coen Johnston

      Hate those plastic deburrers, brake them like tooth picks, or maybe I'm just an animal. Thanks for the video.

    41. woopimagpie

      I thunk the slow motion shots are my favourite part of these videos. And watching repair work on machines I will never use is fascinating. I'm amazed at how much knowledge I'm gaining, especially by comparison to many of the more "regular" machine channels. I'm not entirely the knowledge will ever be useful, but I'm really enjoying the content regardless. There's just something fascinating about watching the big equipment getting fixed. Great stuff.

    42. Johnny Mac

      Thank goodness all that foul language was cut out of the video.

    43. Erin Manthey

      Love the outtakes


      Le informo que es UD. Un profesional tu le doy un 10 en su oficio. Yo me he dedicado toda una vida a la mecánica en sistemas de inyección diesel ,en todas las marcas del mercado ,ejemplo CAT. Komatsu,Perkins etc.

    45. Zeno elea

      Brilliant, cant stop watching your videos. Your engineering capability is awesome and the equipment and tools you have is to die for. The video music and especially the slow motion is really effective.

    46. ITO

      Cutting thread looks like voodoo magic.

      Nice Job, nice late

    53. David Rinpe

      at 3mn10 he s remember me the t1000 in terminator 2....^^

    54. R3NTAC0P

      How important is the O.D. in applications like this? I was wondering due to the time save it would be to not cut the O.D.

    55. NickmannedOne

      In last moment he knew he fucked up... My regrats Kurtis! That was painfull.

    56. NaberAuto

      As a machinist for over 50 years, I really appreciate seeing complex machining solutions such as this on large parts. I am curious that you never turned on the coolant until the boring of the new cylinder? Do you normally machine dry?

    57. Juan Di Martino

      Desde Argentina muy bueno el trabajo que realiza,y el método de solucionarlo, felicitaciones!

    58. Sociopathic Narcissist

      Do you source your raw materials here in Australia or do you have to buy offshore?

    59. alekivk

      How do the zig zags help it come out?

    60. Bill Moss

      Enjoyed the sound of the rain, rather relaxing. Thanks for the video.

      1. Cutting Edge Engineering Australia

        Glad you enjoyed it

    61. Fung Chi Leung

      Experienced worker takes years to train ! The one able to do such an operation at least over 10 years in the trade ! Thanks for sharing this experience !

      1. Cutting Edge Engineering Australia

        Thanks for watching mate appreciate the comment

    62. Jcreek201

      Goddamn it, Carl.

      1. Cutting Edge Engineering Australia

        Thank you very much!

    65. Ojo Felix NM

      Isn't he the lucky dog to have you give him such a wonderful life? And how lucky are you to be part of that fine fellows's life? Thank you kind, caring soul. And regards to our allies who have stuck with us thru good and very bad times.

    66. trangia94534

      I noticed all of your measurements are in metrics except pipe OD and ID. Did you know there are only three countries in the world still using English units? Unfortunately the USA is still one of them.

    67. Helio de alcantara da silva

      Muito bom se isso fosse mostrando ex antes creio muitos seria especialistas e mestres parabéns. Muito top VLW

    68. Rad Restorations

      Love these restoration videos. Cool to see the professional level of restoration. Mine are alot more amateur.

      1. Cutting Edge Engineering Australia

        Thanks for watching

    69. Jim Brent

      I love the caption at the begging... "We are having alot of rain" ... oh thank you for informing us, that's very helpful in the event we didn't see the rain in the video... very helpful... LOL "Thank you Captain Obvious" LOL

    70. 125spectrum

      This is absolute, quality. Really appreciate what you do and the time it takes, to allow us a view into your working life. Thank you. Paul, Scotland

    71. Steve Markovitz

      what kind of TIR spec on this particular shaft? i see quite a bit of "wobble" when youre turning the actual shaft. just curious

    72. Дмитрий Нелюбин

      ничего не понятно, но очень интересно

    73. MrRaf134

      big respect from Poland very good job

    74. Hague1970

      would be really interesting to know what you're charging for these kinds of repairs

    75. Paul Mann

      As a senior heavy equipment mechanic from manitoba canada it looks like your doing a great job. Now I can see what it takes to rebuild all the cylinders we have sent in for repair thanks. 👍👍🌟🌟🌟🌟👍👍

    76. john maxwell

      You sir are an artisan. I'm not a machinist but your skill and knowledge are spot on. I am fascinated with watching your work and skill. You take an otherwise damaged piece of junk and rejuvenate it into something beautiful and amazing. Cheers from mid West US. I Look forward to more videos.

    77. David Sharkey

      "Hi Carl" 🤣🤣

    78. Bienvenido, Jr. Cabrera

      You guys are amassing.

    80. davevanden1

      you are a master buddy

    81. peace frog

      Love the way how shiny the metal looks

    82. owl3764

      I actually really loved the sound of the rain all the time. I guess it comes from us being an often rain starved country. But to me, there's nothing quite like the rain on a tin roof or shed. Unless it fucking floods...

    83. baggerf14

      Is this a one man one woman shop? One dog too?

    84. Joe Huff

      It would be interesting to know how long some of these processes take.

    85. linkuei83

      You've done all this great work only for the doggo to steal the show lol.

    86. Toby Groves

      I wonder if your customers ever watch these videos to see how their job was done.

    87. georgianbents

      That's some amazing work and tooling. What are the tolerances on a job like that?

    88. Рамис Ахметов

      Ты наш ! Наш родной сварщик!

    89. Рамис Ахметов

      Мужик ! Ты супер ! Ты мастер !

    90. Chickenandfriends7883

      I think I just found my new favourite channel! Love the videos. Keep up the great work!

    91. Not Dave

      What happens if you try to weld without any grounding on the part?

    92. Pitt Brad

      I should have listened to my Mom and learned a trade! ... great to see a professional tradesman at work! ... thanks Kurtis. 👍

    93. heavyweight

      25:46 - we all know it, lol.

    94. Maximus Aviation

      If you dont mind me asksing. How much would a job like this cost a customer?

    95. Toys by George

      Amazing one-man machine shop (not neglecting Dog & Mrs Kurtis). Curious to know what a job like this costs being so labour intensive as opposed to getting a new part?

    96. Dave Brown

      Pardon my ignorance, but why no cutting/cooling oil or fluid? Would it help with longevity of your cutting bit?

    97. Валерия Маликова

      Очень нравиться ваше видео! Спасибо за русские субтитры

    98. Iain Chalmers

      Just as well you can weld, cause you sure as shit can't talk hahaha!¬

    99. Zarimi

      Love your channel. Keep it up and and don't bother your video with bullshit background music.

    100. Patty O'Doors

      Excellent thanks.
