Repair BROKEN Hydraulic Cylinders for CAT D11 Dozer | Part 1 | Making a New Eye
This video is Part 1 of repairing a pair of BROKEN Hydraulic cylinder rods and eyes for a Caterpillar D11 Dozer ripper lift cylinders. The eye has completely broken off one rod, the threaded end has broken off the other rod and there is also a seized nut! This shows the step by step process of making a new eye for the hydraulic cylinder rod including machining, boring, milling, drilling and tapping. We also show gas axe cutting off the seized nut using an oxy gas cutting torch and machining the good eye off the broken cylinder rod ready to fit onto the new cylinder rods which we make in part 2.
In this video we are using:
- Hafco TM-26120G Lathe
- Hafco TM-2140G Lathe
- BM-63VE Milling Machine
- HMP-150T Hydraulic Press

Never before seen video
Усталость металла, инженерам необходимо пересмотреть конструкцию, усилить
"coming soon" - OK. I'll stop looking for it now... *whistles innocently*
Another great vid. The detail is good. How come the lathe got a clean?
have you had a chance to use any of the boring bars you recently made, or have you not had projects for that big of a bar yet?
The explanations are the differentiator for this channel. There are many machining channels but the knowledge here of machine failure modes and how to fix them is pretty unique and makes the machining more interesting to watch, because the part kind of has a story now.
Hey mate that's a great piece of feedback and glad the explanations are helpful 😎👍
That's why its cutting edge engineering... not cutting edge "machining"...
The best skilled tradesmen usually know more about their field than most engineers..
@@CuttingEdgeEngineering I second this, i really like how you explain what happened or why you are doing what your going to do. :)
Totally! Big TV networks think people Like us want to see the drama of the construction company having a down machine with a bunch of dramatic music, when in reality people like us want to know the details of how it’s repaired haha. Keep it up CEE!
D11T's are something I work on daily at work and have replaced many many of these cylinders. Your channel is that interesting enough that even though I work 12 hours a day fixing this stuff, I still watch video's like this, just a little incite to how good the channel is Kurtis. Can't wait for part 2.
Hey mate that's fucken awesome thanks for watching glad it's enjoyed 😎👊 respect
Karen, your camera work gets better and better with every episode, it has always been great, but the angles and shoots your are getting are fantastic.....hats off to your skill with the camera and editing..... .Cheers, Paul
Wow, thank you!
"I'm going to set this up in my smallest lathe", way to make us hobby machinists feel inadequate 😄 Great episode guys, keep em coming!
If I look at it just right, that means my Sherline "beats" Kurtis at something. Yeaaah, not really.
I recently moved from California to Alaska and my 14 x72 lodge and Shipley lathe was just to heavy and big to move wit me and after 15 years of having it I had to sell it. Only thing I miss about California is my lathe!!
"Smallest slathe".
Great vid. I can almost say from experience that the rod was repaired on-site and the owner at the time was told this is a temporary repair as the owner had said "I need the machine asap, I can't afford the down time". I love how you have looked at all the components and deduced the root cause and subsequent failures ;) Top job ;)
It’s only temporary unless it works- Red Green
*"I'm the Boss!"* .........."when you're not around!" *"I do what I want!"* ............. "if Karen says it's OK! 😂😂😂😂😂😂😅😂
So true! We all know who the boss is 😂
‘’ trying to push something in where it doesn’t belong ‘’ words of wisdom right there
YOU FINALLY SHOW THE INDOOR CEILING CRANE, EXCELLENT!!
Another great vid! It's surprising just how much detective work is needed, along with the machinists work. (And some really good camera and editing work too!) Thanks and keep 'em coming.
Glad you enjoyed it
just love the way you explain where these things come from and why it failed as it takes the guess work out of things for us that don't do the big stuff or hydraulic rams E C T also you explain the fix then show us in detail of how it's all done just love your channel keep them coming
That's some great feedback cheers mate!
A man who knows his job, also knows that it's just as (if not more) important to know why something failed. Too many monkeys are just happy to stick things back together and wait for them to fail again.
@@donfink7063 Could not agree more as i say i don't do the big stuff but small stuff fails for the same reasons from watching you learn from leaning you improve your knowledge and as we know knowledge for the next job makes things easier cheers
I paused the video at 8:00 to write this comment. The detective work you did in determining what actually happed is the mark of a true professional. You could have just did the repair and sent it off. Instead you did due diligence. Its nice to see people with this integrity.
Finally someone who knows what he's talking about.. Love your channel bro. Greetings from Germany
Glad you enjoy it!
Structurally speaking, when the two rods differ in length, their movement introduces a moment force in the rods. Moments are multiplied forces that twist. So, a 1 pound moment over 4 feet results in a 4 pound force. In your pistons, we're talking about 1,000 pound plus forces multiplied by 4 feet resulting in a 4,000+ lb force. These forces cause one or both rods to fail. Although steel is extremely strong, moments can tear it apart.
When I was young I liked watching older guys blow things up. Now that I am getting older, I LOVE watching younger guys fix broken things. Great channel. Keep things working for us.
Super nice that you investigate the cause of failure and explain it to us and you repair it correctly after! Easy to give that a thumbs up right at the beginning
Curtis, your customers are very fortunate to have you around as a resource of knowledge and skill. Your explanation of the mode of failure, the die penetrant test to determine that the other ram was about to fail the same way as the first one saved them time and money in the long run. Its obvious that this is not your first rodeo. Quickie repairs in the field done under pressure to get back into production very often result in creating more problems than they solve. Love your channel and Homeless the dog. I look forward to all your vids.
Another great video! Explaination of failure, quality of machine work, and video editing is second to none. Homie and his chicken were a great addition. Keep up the great works! Cheers
Cheers mate thanks for watching 😎👍
Having had Staffies for many years, I am convinced in asserting the fact that The Safety Officer's rubber/plastic chicken did not remain in one piece for very long.😂 Thank you for always including him in your uploads, seeing him always makes me smile. Great video as always, looking forward to part two. All the very best to you Karen, Kurtis and Homey.
Every episode has wonderful machining and engineering for me to watch. However, I get to call my wife in to watch for a bit when Homeless grabs a package off the desk and rips it to hell. We have Scotties and any new "indestructible" toy is gonzo in minutes.
@@normstafford2142 Not surprising, my wife also gets great enjoyment from watching Homey open his packages, as I am sure that many other wives do as well. Hahah........quite amazing what our special four legged family members consider "indestructible".
That big smile at the very end.. How can you not love that dog!
Thank you for keeping language clean. I've been watching your vids with my 4 and 6 year old and they are asking tons of questions.
don't let them watch the outtakes 😬😂
@@CuttingEdgeEngineering I always shut it off before when they are around. You have to let it out sometime!
The ability to explain is a rare quality. 10/10 once again.
Computer repair tech here. I found this channel and love it. Really enjoy the thought process, problem solving and overall attention to detail. Keep up the good work. You are a fine machinist Kurt!
Glad you enjoy it!
I have no machining experience except a little household fixit stuff....these videos are so interesting and educational. Thanks for doing these !!!!
Bruh…. King 🤴🏻 I hope you have an apprentice because Australia needs this
This is very educational. I will show this video to the apprentice, and show him why bolts tend to crack right where the thread ends. The weakest point. Thank you and Karen for taking the time to make these really great hands on videos... It needs repair.. cause it's F****d LOL. Greetings from Denmark, watching the video in the morning, having a day off. Cheers
Hey mate! That's awesome thanks for watching and sharing 😎👍
Love that, "I'm the boss, when your not around" "I do what I want, when Karen says its okay" Cant wait for part 2! Thank you!!!!!
“I’m the boss of this house, and I have my wife’s permission to say so!”
Your descriptions of the various operations to complete a project have become much more coherent since I started watching. Nice chicken. Fantastic videographer.
Thanks John, good to know i'm getting better, might get it down to one take soon! 😂👍
@@CuttingEdgeEngineering I have a great appreciation for your skills as a machinist. Plus the outtakes are a bonus. My trade is hvac/r and has been for 45 years. Anyone who has mastered a trade and has the guts to film it, has my vote. The biggest thing I take away from your videos, other than the machining, is that your wife seems to tolerate you 24/7 with minimal violence and also edits the videos. Cheers.
Absolutely loved the forensic dignostic stuff at the beginning! Keep up the great work 😀
Great to see the investigative work beforehand to understand the reason for the failure.
It is always great to hear that "loaded up" cutting noise when you get through the skin and have a good clean cut, well done guys and Bully.
This video might be about engineering but it is the chemistry between 2Ks and H that makes them so enjoyable. Regards from Scotland and a massive thanks for making a dull winter day seem much brighter.
The chip breaking geometry on that CNMG insert is fantastic. Lots of little chips.
Knowledge sharing on a whole new level. We could listen to you guys talk about rods all day 😉
I have to ask you Karen: Are you professionally trained in camera and editing ? If not your natural talent is amazing.
No professional training I'm 100% self taught but always had a passion for photography and like to consider I have a bit of an intuitive style 😁
@@CuttingEdgeEngineering Then I am even more impressed than I was. You are quite gifted
This video is a perfect example of the difference(s) between a Welder, Fabricator and Machinist. Kurtis is a Machinist.
LOL, Great fun, I haven't seen a rubber chicken in years. He is really a happy boy eh. I so love to use the overhead crane to lift a piece into the lathe. It starts out as a thing we have control of the beast. Kind of an empowering feeling for sure. You know how I love big and Kurtis, this is perfect ! Thanks for the fix on this fine Friday afternoon my friend. Big thanks to you and your talented lady.
Cool to see the wear rings and seals in their application when your repairing some of these machines. As a Machinist/Mold maker, I've worked for SKF for 30 years making molds for many of the type seals and wear rings you use. I enjoy your videos, thanks for sharing. 👍👍
that is cool thanks for watching
Excellent demonstration of failure analysis, this is how we learn, asking how this happened and why. Great job and great filming, enjoyed, cheers K&K&H!
Glad you enjoyed it!
That's my Saturday morning coffee Viewing done,brilliant. I love how every decision has purpose. 😁
Hello from Ukraine,I will see you every new video. Very nice work 👍👍
Great stuff as always. I really enjoy the failure analysis discussion to start videos. Pretty fascinating to learn how things go wrong.
After watching about every single video and seeing every outtake. I don’t know how the hell you do it. Cheers to you for saying “end stroke” several times, and having it in the video without saying “fuckkk”
🤣 pretty much seen it all and heard it all now
Love the sound of a sharp drill going through that material.
Kurtis, Rance here. Can’t say enough good things about your work and Karen’s editing and videos. Very enjoyable !
Not only fabulous engineering content, but also exceptional video editing. Thank you for taking the time to make and share such interesting and well thought out content. 👏👏👍😀
Welcome mate thanks for watching
I love Karen's concern when you said it was gonna hit the machine. "Oh Dear!" cracked me up.
Привет из России Я не токарь но все Ваши ролики смотрю с удовольствием Приятно смотреть как работает ПРОФИСИОННАЛ Удачи во всем
In out house I make all of the important decisions. Karin just decides which decisions are important. I really enjoyed this video. I try ahead of time to figure out how I would do the job, which really means I try to figure out how Kurtis is going to do the job since I am a KZhead machinist. I did think ahead that there might be a spigot in there and it made me smile when there really was one. Looking forward to part II. Thanks for another top-notch video.
Great to see you Interesting job for the start of the year. Mercedes were the only car manufacturer we had to perform dye-penetration checks on the years we produced for them. Looking forward to Part 2 of the series. The investigation of failures was one of my favourite jobs.
Holy crap. those rods were knackered alright. Good bit of detective work and nicely explained in the intro. This video has to be the best one yet that Karen has produced, well done! Love Homey and his chicken! 😎👍😎👍😎👍
Hey Fred thanks very much always great to know our long time viewers are still enjoying the vids 😁👍
Watched part 2, but had to come back to the beginning to see the full effect.
So cool that you added labels "before" and "after"!!! It was always odd in the previous videos to suddenly see out of order footage without warning. 👍👍👍
Really great episode with lots of new techniques being used. And really super camera work. Thank you!
Absolutely! Karen is a pro with the camera!
Love the wheel barrel for catching your torches molten metal/sparks Thanks for another informative video
That's my workshop swarf wheel barrel 🤣👍
A fella can learn a lot watching you....I don't care who that fella is!
That 50mm Twist drill is brutal!
Yup, jut as I thought, very interesting vlog. Well done, Kurtis for figuring out what went on and in explaining where all that lateral force/torque came from. The final reveal was most interesting too. I bet the owner didn't know that either? Looking forward to part two. By the way, neat work with the gas axe. I must admit I couldn't see how you were going to do that without melting the whole thing down. I've never seen "Precision Gas Axe" work before!.
Great video! How's the new quick change working on your super clean lathe? You liking it? Can't wait for the new video, hope I don't have to wait 1 week but completely understand. Thank you for taking the time out of yours and your wife's life to make these videos. They bring a lot of joy to your viewers. For me it's a lot more personal, my dad died 5 years ago and he worked for California State Hwy (Caltrans) and he worked on just about everything, like you and your orange shirt looks just like the one he wore everyday. So watching you is like watching my dad work and it brings me so so so much peace. Thank you again for both of you two working so hard.
You're a smart man, Kurtis. You and the Mrs. make a good team. My wife worked with me trimming houses until she realized she was doing the grunt work. That and the ridicule she received from contractors as a woman on the job. If youtube had been around back in the day, I might have had her shooting video...if I had the brains.
I love how you guys post a great video and then spend a lot of time reading and replying to comments, even if only to say thanks for watching!
6:58 That gently, not-so-confident push on the stop button
Was waiting for Kurtis to yell "bang" 😂🤦♀️
Yeah, I noticed that finger to be a hell of a lot better looking than Kurtis's.
What a pleasure to watch you guys. Time flies when I watching you. Thanks for sharing.
I love the way you explain each part and how they are used on the job out in the field.
As a D11 operator it’s interesting to this side of things! Great work man🤙🏼
Hahaa nice! Was this off your machine? 🤣
@@CuttingEdgeEngineering hahaha not unless you doing work for a blackwater mine then chances are no 🤣
@@CuttingEdgeEngineering Of course it wasn't his fault! I wasn't there, I'm in a different country, but I work in trades and the simple fact is that F ups are the fault of the guy who isn't there when then the boss's is asking about it, or even better the guy who left last week😁
Awesome, would you feel or hear those sort of breakages from the drivers seat?
@@brettymike with the eye breaking like that you will definitely notice it being broken even trying to lift the ripper itself
Hey mate - thanks to the three of you for another great video. I was wondering 'how much is too much' in rod length discrepancy for machines like this, so cheers for measuring and explaining! Hangin out for the next part.
glad that helped thanks for watching
Hammering the flaming nut was awesome!!!
Gotta echo a few comments here. The explanations you give are to the point and informative, then right to work.
Another great piece of machine work, and fantastic camera work also. Nine times out of ten when doing repairs there is usually a surprise hidden inside.
Good times 🤣👍
nice format! dig the extra explainers peppered around!
Thanks for the feedback!
I am not a machinist. I do like watching a true craftsman at work. The dog steals the show . He makes me laugh every time I watch. Keep the videos coming
Your getting a lot more relaxed and confidence in your presenting 👍
only taken a year 🤣👍
Your production is much sharper and detailed as well whatever your doing keep it up (five star champ)👍
Great fun. Sometimes you must feel like an archeologist trying to figure out what has been done.
I had a cat like that I had to fix that we bought at an auction. Just like you said I finally figured out one ram was longer than the other and it was tearing itself apart.
Well there ya go, someone must have done a bush fix on that one as well
Me to, but I brought it to the vet.
Alot of people who work in fields like this say thier job is boring after a while but to those in other non machining fields its fun and really informative helped me assist my grand pap in some of his garage work
All due respect to Kurtis for the amazing job but kudos to Mrs CCE for the camera work and production quality. It is absolutely spot on perfect. No annoying background music or look at me narration or joking around that you find on some other channels. Just honest hard work interspersed with a little safety officer screen time. Great job as always guys. Cheers from Giddings, Texas. Glad to see Homeless is still enjoying his blanket.......
What do welders and wheel barrows have in common? They’re hard to push around and easily upset!
🤣👍
Ah yes, My Friday afternoon ritual. 2 Chicken burgers, Pepsi and CEE Video. Good way to relax.
Kurtis! Outtakes. We can see that you are a very skilled operative with a lot of experience to fall back on. All you need to do now is remember that it's the chicken who's in charge.
I LOVE THE BUTTON INSERTS!
Sounds like the first eye was Camarata'd back on. "Eh good enough, let's get back to work"
"I'm the boss, when your not around" there's a man who knows his place
THIS 💯
Awesome investigation!!! I love solving these type mysteries.
It's great that you know what comments are going to be asked and address them in the videos. Great job as usual. Thanks for sharing.
"My smallest lathe" *Literally largest lathe I've seen in my life*
Great work team 👍 looking forward to part 2 👍😎
Cheers mate 😎👊
It's the photography that hooks me...... and editing.
'And there you go' ! that says it all from the master! Great content, thanks
Ah the old bush fix..how does the saying go..there nothing you cant fix with a welder and a grinder.. Guys (Karen) your video quality is the next level.. thanks for another great episode.. cheers and beers..Patchy 🍻🍕🍻🍕
Hey Patchy hope you're looking after yourself mate
@@CuttingEdgeEngineering yeah guys where good down here in the bega valley.. hope you guys are keeping safe with omicron going rampant up there..
Welcome to another "for fucks sakes" and "im going to scrap this machine" video starring Kurtis!!!! Go Kurtis!!
🎉😎🎉 good times
After a couple of days dealing with numptys, watching yr vids is better than a bex…
Glad to see you're collecting your sparks!
Do you sharpen your drill bits by hand or do you have machine for that? I can see that Karen is helping more than usual :D Great video, looking forward to the next one
When you said there was 5 mil difference in length my first thought was "holy shit!" As someone who measures in bananas even l knew that was a significant difference! Lol. That's roughly 1/5 of a banana!
Hypnotic. Relaxing yet educational watching a craftsman doing what he does best.
Amazing craftsmanship can't wait for part 2 it's only minus 39 tonight here hate winter.
Kurtis, i find it hard to figure out how you could get a 2 ton Helicopter in a press that size ? Regards Richard 🇬🇧
🤣🤣🤣 i'm a man of many talents
@@CuttingEdgeEngineering you certainly are, great Video, and how do you keep your hands looking so good ? i liked your nail varnish when you turned the press off as well, ? 😁
👍
OK, how the hell Matty?
@@lancer2204 on the ball mate like a fat kid and a cupcake 🧁
Curtis you truly are a professional at your trade and your wife’s filming and editing skills are a match. You as a team are a pleasure to watch. Keep up the great videos.
I was totally going to ask what a spigot was but i waited till the end ... WORTH IT
Yup. In the States a spigot is a faucet, a cock of sorts.
