Repairing a Cylinder Barrel for BIG D11 Bulldozer! | Machining, Welding & Honing

Published 2024-01-25
We’re about to inject some fresh steel into this cylinder barrel off a massive D11T bulldozer! This isn't your average DIY project. This cylinder barrel is part of a key hydraulic component off a Caterpillar D11T bulldozer blade, responsible for tilting the heavy chunk of blade forward and backwards and also tilting the blade left and right. Watch the power of machining as we disassemble the old damaged barrel before transforming a plain steel tube into the perfect new barrel courtesy of our trusty lathe. Then with the help of a trusty welding torch and a steady hand we’ll weld the new barrel to the cylinder head flange before using our Sunnen horizontal honing machine to hone the new barrel to precision spec. We continue the job by fitting, aligning and tacking the barrel end to the newly honed barrel before some more flawless welding to complete the repair!

In this video we are using:
- Hafco TM-26120G Centre Lathe
- WIA 500i Weldmatic welder
- Sunnen HTA-4100 Horizontal hone

    Karen's production skills are just as impressive as Kurtises work. No wind noise, no waiting for autofocus, appropriate fast-forwards, and interesting subject matter. I like it when there's a clock in the shot. Good work!
  • @Hey_Its_That_Guy
    The look on Kurtis' face when Karen asked him if that was her tea towel...precious! 🤣
  • @LesDexia13
    It never gets mentioned but the sound recording and editing in Karen's videos are phenomenal. The ambiance is always very natural, and the way she mixes normal speed audio with sped up video is so subtle it's easy to miss.
  • The look on Curtis' face when Karen asked, "Is that my tea towel?" in the bloopers is priceless! I knew exactly how he felt when confronted by the wife!
  • @warpo007
    no words ever spoken to a man more terrifying than: "is that my tea-towel?"..... the look on Kurtis's face, we have all been there.. RIP Kurtis..
  • @boydwoodgyer2139
    “ Clearance is Clearance “
    That has to go down as the first Kurtis Klassic for 2024 .
    Keep up the good work & the entertaining bloopers .
    Bit more Homeless content too .
    Cheers 🍻 , Woody NZ 🇳🇿 .
  • @Fearmocker
    Man, the anxiety I get when I see those tight clearances lol. I can see how easy it would be if someone wasn't paying really close attention to the details of how things can go really bad real fast. Such a pro man. Bravo. Also a huge kudo to Karen for her filming and editing. Such a great job as well.
  • Just like clockwork 11 PM in the Pacific Northwest up Pops, Kurtis ,The Mrs. and the safety officer… sleep can wait yet again
  • @mercutilis
    That freeze when she asked if it was her tea towel, that look is so epic! 🤣
  • @keithm6117
    Kurtis always looks to be confident in control and on top of the game, right up to the point where Karen ask's "is that my tea towl" then the look of doubt & second thoughts on his face for that moment is priceless..
  • @jaybailey8044
    Crutis, I feel like I have been going to machinist class watching your videos. I wish I could have seen these when I was a young man going to trade schools. I'm too old now but I fully enjoy watching you and Karen working on these videos.
  • @AshleyHorne1
    As a D10/11 operator it’s really good seeing these because every time I walk up to the machine I look at all these parts and know how they get disassembled and built back up 👌🏼
  • @L36VS
    Happy Australia Day All the Aussies in the chat .🇦🇺
  • @Ty-bz7zx
    "Is that my tea towel??" Gave me a good chuckle. I have been caught by the "boss" a few times in the shop with inappropriate "rags" for various tasks & cleanups. =)))) Safety Officer should have given you a warning bark!! =)
  • @Marty54GMC
    You asked what is our favorite part of the video? That's hard to pinpoint. What I think is cool is when the button insert just cuts to the point where the smoke from the hyd. fluid ignites. The anticipation of waiting, is something I've always enjoyed. As always a great video. Today has to be the "is that my tea towel".
  • @MK-jo1gi
    'Is that my tea-towel?', followed by a seriously guilty look. :D
  • Is it just Me, or is there something cool about watching Button Tools Cut!
  • @billmullins6833
    Watching that barrel drop out of that flange was SO COOL! Pleasure to watch you work, Curtis. Absolute pleasure to watch you work.
