Repairing Parts for Caterpillars BIGGEST Dozer! | Machining & Welding
Вставка
- Опубліковано 16 бер 2023
- We’ve got an urgent repair job to do so we can get our customers big Caterpillar D11 Bulldozer back to work! We have a pair of blade lift yokes off the D11 Dozer with worn out bearing surfaces that need repairing. We show the step by step process of the repair starting with machining down the worn surface using the lathe. With this being such an urgent job, we use Stoody 965-g hardfacing welding wire to build up the surface which will give a hardness of 55HRC. Once the weld has cooled down we machine the yokes back to spec in the lathe.
In this video we are using:
- Hafco TM-26120G Lathe
- Weldmac WHP-2.5 Power tilt positioner
- WIA 500i Weldmatic welder

Some "interesting" sounds were made when machining these hardened D11 parts 😅 Hope all your ears are ok! And it's crazy to think how big these parts look spinning in the lathe but they look so little on that massive CAT Bulldozer 💪

Good Evening Karen, Kurtis and Homeless.....Cheers from The Other Sunshine State.....Paulie
Get kennametal new insert Fix8 suitable for every kinda steels and has 8 cutting edges
Previously, finished parts were simply taken away into the darkness😂😂😂
That’s quite a screech
I felt sorry for your truck when you put the pallet on them. One forgets how heavy steel can be!
Customers that can afford a D11 are good customers.
I won;t lie - I'm about 70% here for the machining, 30% here for the outtakes, and 100% here for any scene with your dog. He's just the best.
I'm 79 and I operated a similar business, albeit on a smaller scale, in Saskatchewan Canada for over 30 years. I really enjoy the fact you don't edit out the parts where things don't go as planned ie: harmonics in your huge "tuning forks". Those of us that have done these repairs know everything does not go as hoped and good on you for showing us the difficulties and how you overcome them. Keep up the good work. After you retire people will let you know how important you were to their daily operations...not so much when you're actually operating the business.
You never cut corners and Always look out for your customers. You make parts better than new!
To be fair, the out-takes are just as enjoyable as the serious engineering vids. Also proves that Kurtis is human, and not just a metal-working ninja !!!
ninja? another mis usage of a word. What does Ninja mean Japanese?
Image result for ninja
Ninja (忍者, aka shinobi, meaning "those who act in stealth")
@@araofmadisoncasey4247 are you a plonka ??? Or just a troll..??? The informal meaning of ninja is to have attained serious skill levels. Look it up, prick !!
@@araofmadisoncasey4247 Ok we get it you think you're cool for going "um ACKTUALLY"
(You're not cool. Stop it.)
My favorite machinery channel
Big shout out to Mrs CCE , she's the most talented camera lady on UA-cam 👌
Hey Jose thank you for the great comment I appreciate it!
From Mrs CEE 😁
@@CuttingEdgeEngineering You as well Mr CCE , you are a great machinist 👌 Cheers from USA 🍻
👍💪✌
Yesterday the UA-camr Dirt Perfect had an employee wearing one of your shirts, and the comment section was raving about it. You guys truly are highly respected globally, and genuinely deserve it. Your videos are the best part of every Friday.
@Cutting Edge Engineering Australia The best person on UA-cam at filming without a doudt!!!
I truly love the outtakes at the end. I've been following your content for years now, and the outtakes are about the only time one ever sees him crack a smile. Do more of that, Kurtis.
hey mate glad you enjoy them!
I love the outtakes and Homeless.
Oh… ok, that’s Kurtis…… we’re only 35 k’s down the road here on the Goldie !
ur wife, rather, her work can’t go unheeded … sensational! roooley & truely!!
Seriously? You like that? That is actually the only reason I can not stand this channel! Once, ok fine. Twice, I guess but 3 times and by now everytime? Just simply unacceptable!
@@realemonful you know you could always not watch them? 😂👍
Dammit, I love hardfacing, and bearing surface replacement in particular (hey, don't kinkshame me!). Too many people will try and tell you lasers are the future for deposition, and having worked with lasers for 30 years - long live arcs! MIG deposition, done well, does a tremendous job for so many applications. This video shows you just how.
CEE make my Friday mornings complete. Keep up the good work!
Homeless is such a hoot. Those packages don't stand a chance. Interesting video. Thanks for sharing.
I'm thinking of the stress the owner of these massive machines must be under when urgent repairs are needed and the machine shop delivers within the strict time limits, I think CEE has a customer for life from now on in. Thanks guys, great video.
They're probably fine. I imagine their stress is like Fry in Futurama when he drinks that 100th cup of coffee and reaches full zen and gets super speed
Time is money when one of those machines goes down.
One would think so, but a lot of time they quickly forget when someone else is 15 cents cheaper.
@@cullenmiller8170 Local and smaller operations will never forget and be forever grateful - big companies can quickly forget when the new manager knows a guy he use to use....
As an ex maintenance superintendent it depends if it’s a pm related issue or found work …….. while this machine is down it will be having other critical maintenance done to it …. Maximizing down time to increase up time in the future …… it’s all part of the game
Sympathetic resonance can be a hard thing to eliminate. Well done Kurtis job is a good one. Karen and Homey, being the back room support. Thanks to all 3 of you for making Fridays a great day 👍
Brake drums ring badly as well. A leather strap works. I grinned when Curtis went for the banding strap. I was expecting leather.
Leather straps smell too much like a new car to be used like that 😂 🤪
It’s been 20 years since I have ran a lathe, but I can vividly remember the unique feeling of that surface, that was “smooth” yet rough at the same time, from the harmonics. Thanks for the memories.

TAFE needs these videos in their curriculum for real world machining and servicing demonstrations. No bullshit, only relevant information without product bias and real-life examples of problem solving on the job. Kudos again Kurtis and of course it's all because of Karren for the amazing videography, it's purposeful and lint free.
Yeah...what not to do... Jesus Christ
I think your welding skills are often overlooked due to how proficient you are on the machines (lathe, mill, etc), you do an outstanding job with that MIG gun.
Very well put, sir!
I really like watching you repair those bigger pieces of the machines.
Karen you're so wonderful at all that you do.
Homeless loves when he gets to open his mail. It so much fun for me and him.
I ALWAYS enjoy watching your shows.
Kurtis you probably have very satisfied customers when you can get them back to work that quickly.
Keep em coming.
K&K: _prepare mail shoot_
Homeless: _appears_
K&K: _Somebody set up us the toy._
Homeless:: _All your mail are belong to us._
Do not bother but today, the best of the video is the face of the puppy when he has opened the first package and is with his paws on the table waiting for the second. LOL.
Thanks for your invisible smiles Karen.
Straps, scraps, sticks…you can turn anything in a tool, that’s what makes you the best mate!
Somehow the wife and I (she’s an accountant I do network stuff) have been watching you two for a week straight during dinner, much love and appreciation for you both sharing your shop with all of us.
Despite the time constraints you cut no corners, and (on camera) appeared as calm, cool and collected as ever. Well done !
Your skill, talent, & knowledge BLOW MY MIND. I hope your customers know how lucky they are.
@jamesarnold6059 - strongly agree.
That’s the second time I’ve seen straps used like that to drive a part on centers; both by Kurtis. I didn’t know it could be done until I saw it on this channel. Hats off from America!
The strapping "drive dog" was genius....hell of a job!
This guy has forgotten more than some so-called "machinist" of today know. WTG Curtis!
I'm sure there is no pressure at all when you know that they have to ship first thing tomorrow morning. Great work Brother. Thomas, Mississippi, USA!
Time to burn the midnight oil!
I'm always impressed with how much you know about mining/excavating equipment and their repairs. Quality job and great camera work from Karen as well!
Oh wow! I watch your channel too! Although your work is on a far smaller scale, it’s so fine and intricate and just as entertaining to watch.
Of course, I like the welding and cutting but the Safety officer is my favorite part of the shows and the outtakes.
Curtis you and Karen are some of my favorite people.I am very impressed with your skills and work ethic.
Super stoked to see the local companies like OZ Welding Supplies hooking you up with merch. In the US you'd have a new Miller and Speedglass helmet already. It's a shame local Aussie companies don't invest more in great channels and tradesman. Great work again!
Your customer should be very happy to have someone who can not only do a superlative job but who will do it in such a short time span. Excellent video. Thank you from Texas.👍👍
I really enjoy your videos. You give your family " Bragging Rights". My grandfather was a machinest for 30 years. When i was a kid, i never understood his profession until long after he passed away.
THAT is a long, hot job. Especially in your antediluvian heat! People don't understand, it's not just the heat from the job, it's the layers of leather & protection that adds to it all. Nice job! 👍
I watched this early on Friday morning, sitting in the car while Karin, Halgrim and Bella were out for their morning walk. Those big tuning forks play a mighty tune! Great job and I'm sure the machine owners are very pleased to get that monster back to work.Thanks a lot for another very interesting and exciting video. Karen, I hope UA-cam soon has an Academy Awards for videography! You will win it hands down. Hope you have a good week.
Love how you take these dead line jobs in your stride.
Throw in a professional video to boot, that's teamwork.
There is money in rush jobs
It’s always amazed me how time lines change engineering specs! You did a great job as you always do. Keep Homeless happy!
Karen's bracelet gift put us all to shame, she really deserves that nice piece! This time I really liked the follow-the-wire shot from the spool through all that drive sprockests in the feeder up to the welding gun!
Thx a lot for taking us along on that hard (facing) job!
👍👍👍
There are two constants in life: change, and a CEE video to wake up to on a Friday.
I'm glad to know that flicking a strap after tightening it and saying that'll go nowhere works down under as well. Thanks for the videos.
P.S. Karen is nailing it with the videos and editing.
Nice for people to send nice gifts like them TIG parts. All helps building the business and money that does not have to be spent someday. All helps keeping the company afloat. Some really great people out there.
Using those packing straps for traction and sound dampening was simply genius. Great idea!
Quite interesting! Heard many machinists mention harmonics, but this was a fantastic example!! Also even hearing that high pitched one at 26:13 was brutal lol
So was it the harmonics that caused the preferred bits to not bite?
@@steven.h0629Think about it this way: the Harmonics are the result of vibrations. When it vibrates, it causes small movements.
So sort of, yes.
Fridays just wouldn't be the same without your Machine Shop vids - awesome stuff guys!
Absolute TRUTH! Then "I Do Cars" on Saturday night! Deluxe!!
Rainy day in France, it is always a great pleasure to see your videos. My game with your videos is to guess what technique you will use to do the job. The last time I worked on a lathe was in high school 40 years ago. Bravo and thank you for your videos.
Homeless is a happy camper. Awesome parents.
Thanks for posting now! 3am here on the east coast of banana land, and I'm still awake 😮💨. Love the calm pace and machining content. Was browsing UA-cam, and looking for something to watch. Perfect timing! 😅 cheers!
hope this puts you to sleep, although the sounds of machining on this video might keep you awake 🥴
@@CuttingEdgeEngineering I'm one of those wierd people who sleeps best with machining videos or background noise. By the way, we might be getting a CO2 laser engraver in the coming months. Anything you guys think you might like? 😄
Hey Kurtis, in the future try rapping the shaft of the yolk with a 4" X 5' strip of rubber the thickness of a inter tube. It should help to deaden the ringing when machining, like when turning a brake rotor. Good Luck!! Keep the vids coming, enjoy them all and some times watch them a second time. Thanks
Given the huge elastic modulus of the steel, and teh huge mass of steel compared to the elastic modulus and mass of rubber, I think it would not make the slightest difference.
@@keithammleter3824 it is all about taking energy out of the system. If you leave it vibrate on its own, it will amplify in natural resonant frequency. If you let it waste in something like rubber, you might get lucky and get rid of some harmonics.
I would've liked to try just another strap, but near the of it, or just tack weld a small bar across it.
I agree with John. When turning brake drums the shape of the drum causes nasty harmonics which will result in a herringbone pattern like Curtis had. We use big rubber belts to absorb the vibrations and it makes a much cleaner cut which is nice and smooth. The bigger the brake drum the bigger the rubber belt we use.
That’s also an old watchmakers’ trick to get those last few tenths on humming parts. Sometimes it’s pitch instead of rubber.
Observing how you are always so very good and careful and professional to use all safe practices in lifting all these heavy parts, I can't help but recall the few times I have happened on similar work being done in places like India squatting barefoot and barehanded in the dirt with next to no lifting tools, welding helmets, gloves or anything really at all present for protection and safety. Not blaming anyone. Just feel so sorry for people working so dangerously and heedlessly. And how great it is to watch Cutting Edge show us all how this very dangerous work can be done safely as well as properly. Responsibility, the ability to respond. Man at his best like water, they say, seeks his own level. And saves his own life and limb too. Live long and prosper there Aussies.
The colour of the chips! brilliant. Homeless!❤
I have just come to appreciate that you do a good job of showing the machine and where the part goes.
i like how you explain what machines these repairs are off.brilliant
Very happy that Karen received a gift from a subscriber. Kurtis and Homey, deserving no doubt, but Karen is just as much so. These videos are done to as high a level as UA-cam offers IMHO. Solid performances from all 3 of you as always. Thanks from a entertained/knowledge received subscriber.
Amen, and Amen!
Automatic "Thumbs Up" !!! Quality work at it's best.
The colours of the chips are way cool! You almost had a full rainbow.
Excellent job team CEE. I've said it before, but the best thing about CEE is that although the jobs are massive, all the techniques are scalable down to us home gamer types. It's also interesting to learn little snippets about heavy equipment, an area I am not familiar with. So thanks Kurtis for the excellent machining demos and Karen for the great production. And thanks Homey for just being Homey.
You are right about the scalability of the techniques and it is also good to see no matter the size of the lathe that you can have issues with inserts and feed and speed rates.
Mark from Melbourne Australia
Thank god there are people like you. I hope you can pass your knowledge on to some really lucky SOB
Good video. That pup really has a love for living.
Never fails: "Oh I'm sure I'll never need this thing again, it's been a decade since I've needed it"
tomorrow I'll need it twice 😅
that happened to more than 10s of times
Wow, loooved wire-to-torch camera transition @15:00. Felt really organic in scope of these videos.
I love you guys but homie melts my heart and im a bloke he reminds me of better times. God bless all you guys keep up the great work. Thankyou.
Kurtis, you are amazing. Using packing tape as a drive dog is ingenious. My hat it off to the three of you.
That was really sweet for someone to gift Karen; you certainly deserve recognition for your patience (with both Kurtis and Homey) and care in editing! Homeless was, as always absolutely priceless, and it looks like an added bonus on this job is that it finished while still light out! I've seen a lot of your jobs loaded with the forklifts lights on. Have a great weekend you guys.
I must say I admire your patience and stamina with all that welding and turning considering the size of these parts.👍👍
Best in the business, Kurtis! Great job on your camera work also, Karen!
Had a great laugh at Homey snagging the first package and opening it all by himself. Awesome job on the yokes Kurtis, they turned (ha, turned 🤣) out great. Karen, as always you do a awesome job on the filming and production of these. See you next week.
Never lose the out takes, always have me smiling!!
Stay safe out there you three!!
I’ve unfortunately, only found out about your channel just recently. But I’ve been binge watching all your videos since then! You do amazing work and I love to see it!
hey mate welcome to the channel & thanks for watching 😎👍
Traducir
Watching Homey opening the packages could have lifted straight from the How To Basics channel.
I looking for your videos every days and every weeks, in the first time,n because it was my job when i working in my young time and after because i don't see bullshits on the others videos. AND ABOVE ALL, I REST IN THE PROFESSION.
*Cutting Edge Engineering Australia* Bravo well done, thank-you sir for taking the time to bring us along. GOD Bless.
Excellent, Excellent job, The knowledge and understanding of INSERT composition, abilities and application is a science to itself and very often NOT recognized nor applied to the needs of the job. Kurtis you are spot on with this, hats off for your abilities to do that. Karen as usual is making it all outstanding with her cinematography skills and is deserving of an EMMY......Keep it up.....CEEAUS ROCKS !!!!!!!!!!!!!!!!!!!!!!!
Don
Like many UA-cam watchers, I hve seen many, many, tradie videos.
Yours Kurtis are the best I've seen, by far. Insane skill my friend.
I felt rather inadequate when I changed the spark plug on my mower this morning. I can only dream.
Thanks to all 3 of you for making Fridays a great day
Thank you for another truly well made episode of this week's work, excellent both in production and content. Thank you also for your ever so good patience getting the description shots done, it must be very trying when you have so many outtakes during the filming. Funny to see how impatient the Safety Officer Homeless can be with your packages in the mail, thinking everything is for him. He is well and truly spoiled, but that is half the charm. Excellent entertainment at the end of the week. Thank you again.
Brilliant video again Kurtis and Karen. When you look at the design, the materials and production values that have gone into just a "small" part like that, you wonder how they can sell a complete D11 for as little as $1.2M. That new carbide insert seemed to be the dogs whotsits. Always amazes me how different grades of carbide can make such a difference in a cut.
Because Caterpillar is not in the heavy equipment business - they're in the spare parts business.
@@crunchysupermanSame with just about every manufacturer. Have you noticed how car manufacturers are always advertising incentives to get your car serviced at main agents' workshops?
@@davidstewart4570 better example would be those newfangled all-LED headlights. Sure, it is only 1200 bucks extra on top of standard issue xenons, but god forbid you break them in a fender bender, it will be 4grand for replacement part. Plus labour.
Economies of scale; if you're producing dozens or even hundreds of these dozers a year, it'll take significantly less time for each part's setup. Also, they probably cast and machine parts to size before heat treatment and the final precision cut, which really reduces how much material you have to remove.
Must be gold worth for the mining industry and other heavy equipment operators to have a shop like yours, who can fix these thing in a day and save them from big losses if the machines are not working. I admire how good you are to fix and machine new parts. Greetings from Norway.
Kurtis and Karen - I always enjoy your videos this week Homie made me laugh so much. Great work by the CEE Video/Engineering team as always !👍👍
Every video is not only entertaining but very instructional. Thanks, Kurtis for letting us see you hard at work. The projects you do are just amazing and they show the amount of skill and professionalism that is required to get these jobs done. Respect, sir
Another top job job there Kurtis, if you're going to get a rush job it's better if it's an easier one. Some pretty awesome gifts for everyone this week, this is one channel where I like watching the unboxing portion because of the cool and interesting stuff you have sent your way.
It honestly blows us away the generosity and thoughtfulness of our viewers! Very grateful for such a supportive community 😎👊
You think the harmonics on that are bad, you should hear me trying to sing. Americans are so generous and their postage is just as ridiculously expensive as our. I loved the bracelet, some one put a lot of time into that. Cheers Stuart, Canberra.
Im an old school fitter and turner here in Australia, really enjoy watching your videos, i learn a bunch of stuff with every video, its great! Thankyou to you and your wife, much appreciated, keep up the great work, cheers!
Dan 👍🙂
It finally struck me today, your welding is impeccable! To have no voids with that amount of material added on. Such skill. This of course coming from someone with no physical experience, just a general understanding of the process. Great job and thanks for sharing you three❤
Regarding the howling, I've had decent luck with surgical tubing. Pretty cheap, stretchy and works surprisingly well. You would need the green stuff to drive it, but wrapping the tubing around 3 or 4 times in figure 8s would probably make it silent.
I'm a retired machinist as of last fall. My experience with vibrations has led me to using any old rubber hose ( like an air hose) wrapped tightly and secured seems to work very well. I also noticed threaded holes on the forks, a plate could have been bolted on using all 4 holes, just my thoughts.
Great videos and I too agree the ending out takes are great ! :)
Good idea. I’ll try to remember it, next time I have a high pitched screamer.
Howdy Cowdies. 😁... here we are once again. I went and took my daughter out for tea, came home and Voila.... my favorite you-tube channel just posted another video.... YAYYY
From one machinist to another you are truly an amazing machinist Kurtis! Your problem solving and setups are absolutely genius. Karen you are great also! Both of you keep up the awesome and very very entertaining videos!
Спасибо. Как всегда все на высшем уровне. А работа оператора изумительна.
Да! Наши могут!
о, наши здесь!!!
It's very cool to watch the occasional piece of swarf flare up & glow brightly as it gets just hot enough to ignite.
The classic “going nowhere” when strapping down. I love to see everything you do, thanks for sharing with us
The welding shots around 15:35 are beautiful, great camera work.
"TURD"
i loled. great work as always team. especially liked the journey of the mig wire through the rollers, excellent!
Just amazing that you are understanding the harmonics of the individual metal! You humble me, and you deserve all of the accolades that you get from us Lessor "Machinist's"!!
I wish my Grandfather, who was a Tool & Die trained machinist with 60 years in his trade, was alive to see your abilities at problem solving! He'd be very proud to watch your work. Thank you for teaching us how to be better at what we should be doing!
Your videos are always good, Kurt and Karen, but this weeks was exceptional. I learned:
1. The use of banding to secure the yokes in the lathe.
2. Damming up the ends of the welded area on the yokes prior to welding.
3. Homey opens packages almost as well as a human!
I've recommended your channel to some friends and have gotten nothing but positive feedback.
Thanks for the tight editing and keep up the good work!
Beautiful work, great camera work and editing too. Quickly turned around as well, that should be one happy customer. Well done.
The camera/editing work at 18:40 was really cool. the sound of the arc and the time lapse effect was really creative!! Great work!
Not only knowledgeable with machining but very knowledgeable also with Caterpillar Heavy Equipments inner workings that’s a killer combination and real talent, very good job on that yokes Maite 👍🏻
That sound must go right through you proper job mate you know your stuff
Karen you did an amazing job on editing today.
thanks so much James!
Man, what a monster that thing is! I am not even surprised that these yokes wear out like they do. I hope the customer was appreciative!
Thank you and as usual: May you all have a great 'effing weekend!
hey mate the customer was so appreciative they sent us another pair to machine 😂👍
@@CuttingEdgeEngineering No good deed goes unpunished, eh?
@@CuttingEdgeEngineering can't argue with a repeat customer.
@@CuttingEdgeEngineering just like printing your own money🤣
@@scruffy6151 You can if they don't cough-up on time...
hehe, nice "time lapse" on the second weld up and grind... just ZIPPPP and done =P I always appreciate how much actual time goes into each step, and how neatly and unobtrusively you compress time in the video. I've seen on other channels the joke on a t-shirt that says "welding god" with the word welding crossed out and the word "grinding" written in. Kurtis illustrates the other end of that spectrum. Great video as always.
(another welding joke is "grinder and paint make me the welder I ain't, which certainly doesn't apply here either)
Editing for the second weld and cleanup is brilliant.
They look like stub axles off a giants go cart. Great job again to you both. Don't you hate things that vibrate when machined. Cheers Billo.
Your knowledge of materials is impressive.
The "When I mean a (closes eyes) God-Aweful sound..." I.. felt that in my shade-tree mechanics heart...
New shop-made tool idea: chuck center dog with appendages that couple with the tines of that tuning fork thing. Once the yolk is held by centers, the yolk tines are coupled to those appendages somehow. That will provide drive torque and likely dampen the resonances from the yolk being turned.
