Repairing WORN OUT Planetary Carrier for Cat 740 Truck | Making Custom Boring Bar
We're tackling a worn-out planetary carrier from a Caterpillar 740 Articulated haul truck's diff final drive. The challenge? The damaged gear thrust faces are located within a hard-to-reach location on the carrier housing, making them difficult to repair with conventional tools. So that means we need to make a custom boring bar specifically designed to access those tricky areas with our milling and facing head. In this video, we'll walk you through the entire process, from machining the boring bar on the lathe to the precise milling work required on the planetary carrier itself!
In this video we are using:
- Hafco TM-1740G Centre Lathe
- Hafco BM-63VE Milling machine

Another Wonderful 3 AM here in Florida......the other Sunshine State.... Thanks Karen, Kurtis and of course, Homeless and George and all his feathered friends.... Best Wishes, Paul
May I wish you and your family a safe Easter 🐣
So true playing with metal is much better than eating chocolate 😂😂. Happy Easter enjoy your holiday weekend .🫶🏻🇬🇧🫶🏻
Homie does, homie needs fake choco/meaty eggs for easter, cause gnawing on boring bars in unrewarding.
Have an awesome weekend guys, I'm off fishing!
what I never cease to love about this channel is the attitude of "to get this job done, we're going to need a custom/obscure tool - so let's get the tool made, and then get the job done"
Amazing dedication to his profession and trade. Kudos for not charging for the entire cost of the custom tool to the first customer.
It's people like this who keep the world turning!
@@busking6292 yes I agree. problem arises, solve the problem, create new tech for the world to enjoy
I do this exact thing with my kids. Teaching them if you want it, you need to make it happen.
The mindset of if i need it and can make it why buy it. That's what's needed more of these days. Let's get away from the plug and play syndrome that society has developed.
Thank you for not adding "fake dramatization" into your videos, this make it attractive and genuine. I am tired of some other channels moving a way of "showing the work" and adding "unnecessary drama" while being such a "bad actors".
And the apparent necessity to shout mock excitedly the entire time in an effort to 'keep it lively'.
When you're an Aussie... _there's no drama._ 🥁Ba-dum-tschh
Kurtis has a straight forward approach that puts me a bit in mind of RUSH's Tom Sawyer...
It would be interesting to see a bit of over-the-top drama here one day. Bit of fun...
This!!!!!! No drama. Just getting it done.
I can't get over the fact that I saw the legendary Homeless in person before I found out he was famous. I used to work down the street. Excellent video as always.
The videographer does a really competent job. She conveys all the information in a compact and easily to understand way. The jump cutting is great, saves time and doesn’t get hung up in transition effects which can be an annoying waste of time. The dog ties the videos together. He does such a good job making us care about machining to make money so he can have chew toys. Oh! And the guy who works the machine is pretty good too.
Also, nice to see upping the game with the split screen shots!
I want to take a moment and acknowledge how much you guys have meant to me over these past 5 years ? I can’t imagine what my Thursday night/Friday morning would be without homeless, Kurtis and Karen. Also a shout out to George, the Caterpillar Manufacturing Corporation and their many amazing and terrifying machines. Here’s to another 10 years of incredibly inspiring, fascinating and hilarious videos. All of my love and respect for you all. 🥰😍🙏❤️
Hey mate that means so much to us! We're incredibly grateful to have you along for the ride these past few years (coming up on 4 years since we launched our channel!) Here's to hopefully many more years of even better content! 😎😄🐾🐥
@@CuttingEdgeEngineering it's been fun watching the videos boy time sure does fly buy
What a great team you guys are
Hear! Hear! Long live CEE!!!
Right . For me it’s Friday afternoon🎉
Working Graveyard shift in America waiting for 1 AM every Friday morning to watch the next episode. They never disappoint. Currently trying to be the number 1 thumbs up but very competitive! Thanks for the great content!
Thanks for watching!
Could not say it any better. Need MORE of them WEEKLY.
67k views in 3 hours…🤣
I just got switched to days from evening shift, I have to wait until Friday morning to watch instead of after work.
It's unbelievable how fast people click on their videos😂 I sometimes wonder if there's a delay since we live halfway across the globe
My son was born today, he got to watch his first CEE video with me while he is in the NICU. Thank you for your videos, they mean a lot to us all!
Awww poor old Homie, the look of sheer disappointment when he was left inside, great Vid guys
Such a big baby, typical Staffy needing endless attention 😂
Had dogs that would do this, nothing going on might as well sleep so I'm back to full madness when my dad comes back
I hope you never stop making videos in the near future because we love watching 5,000 people in 13 minutes should prove that lol.
Hey mate, no stopping us anytime soon thanks to viewers like you! 5,000 people in 13 minutes is some serious proof! We're working hard on bringing you more great videos 😎👊
If he did I’d probably drive over and try to convince them otherwise 😂😂. He’s only 10 hours north of me. 😂
136k in 7 hours is a huge number of people who enjoy them!
And that's with most people in the Americas asleep when this is released.
Not only does he make a custom tool for a job that seems to be 'rare' (after all, he didn't have that tool already) - he makes sure said tool is NOT a "rough temporary solution" but a properly machined, good looking addition for the tool rack in case similar jobs should show up in the future. Well done, Kurtis. And as usual, but always worth mentioning: Very good job filming the whole process, Karen (and putting up with all them bloopers)
Maintenance of standards for all jobs. Once you start taking short cuts it all gets lazy.
Let all take a few minutes to congratulate Karen. Without her, this channel wouldn't be what it is. Outstanding camera work. A true professional. And my final comment is "F**king trains" lol
No waffle no advertising. Cutting Edge Engineering and Snowball Engineering. Best marching channels on KZhead. Thanks.
🎼 Iiiiiiiiii, love a parade...🎶 🤔😏😉😁😎
@@markschweter6371 Yes I never could spell. 😄
Found out 'Sowball Engineering' from 'Watch Wes Work'. Good stuff from Good people.
Karen, your camera work on this was exceptional. You have a gift for knowing exactly what to film to explain what is going on. (The machinist is pretty good too!). Enjoy your Easter break.
Wow, thanks so much for the kind words! It means a lot to hear that you enjoyed the camerawork. I try my best to capture everything clearly, so I'm glad it helped explain the process. (I'll be sure to pass on the compliment to the machinist as well 😂) Happy Easter to you too!
@@CuttingEdgeEngineeringKaren you are the komplementary genius here.
@@CuttingEdgeEngineering I loved it last week when Kurtis pulled the trigger on the MIG torch and _POP_ the nut was filled! It was such a delightful effect. :)
You call it a boring bar, yet its actually quite interesting
😂 was waiting for the 'boring' comments to start
@@CuttingEdgeEngineering Hey someone had to say it and it may as well be me
😂
@@CuttingEdgeEngineeringI resisted the urge to make a comment about that coz I thought it would be a little boring.
😂😂@@chrisking7603
Favourite day of the week, Curtis being a genius in the workshop, Homey carrying out his inspections, George and Co bringing the soundtrack and Karen bringing it all together in one perfect package. 👍
It's a real privilege to watch a True Professional work. Your wife's camera work and directorship included! Thank you for sharing ⭐⭐⭐⭐⭐
Thanks for watching!
Wish I could give 100 thumbs up and dittos to this comment. It really is a privilege to watch a husband wife team that loves their work and does it so well. Thanks from northern New England USA.
@@Saltshaker2016 Dittos back-at-cha! Karen and Kurtis are Truly Inspirational! Discovery Channel should sign these two Aussie Love Birds ASAP! 🦜🐦
Seeing that damage on the thrust surfaces, I'm very surprised that there was no excessive wear on the pins or gears. Good catch whoever found the issue. Genius solution to manufacture a specific tool to enable an effective repair rather than a full replacement. Nice one Kurtis, you never fail to impress or to entertain !! Thanks dude.
I’m guessing it’s because those gears will have been face hardened whereas the housing has not
Could have been it damaged the shim stack, but that's cheap to replace.
Midnight here and up pops Kurtis like some crazed machining Easter Bunny…in other words,a normal Thursday midnight!
"F O T" on the wall by the door. Love it! Someday a little primer on how the centering device works please. Looks simple, but there is magic there someplace.
Life isn’t complete without CEE vids
Good morning Cutting Edge Engineering Australia, greetings from Germany 🇩🇪 !
7am U.K. = machining time!
I'll second that ! ⚙🔩
Good morning from the UK Folks. That was a very elegant solution to a tricky problem. Thanks to you Karen for the great video shots nice job Kurtis. It was great to see Homey enjoying his shop time, checking everything was in order.
Hey there from across the pond! Glad you liked the solution, it took some thinking for sure. Thanks for noticing Karen's awesome camerawork, she really captured the whole process. Homey's the official shop supervisor, gotta make sure everything's up to code!
It is not gonna be long now until you guys hit the magical 1,000,000 Subscribers. Already hit 750K. Just remembering back when it was Lockdown and I clicked on your video because of the Safety officer. Good times.
I'm receiving my first benchtop lathe on Monday and I feel like this channel has been one of the driving forces behind my interest and adventure into machining. Cheers from Michigan.
Thanks bloody awesome mate! You'll have to let us know how the first cuts go 😎👍
Which benchtop lathe did you end up going with? I'm just curious as I, too, am anticipating getting my first lathe and have been investigating for about 18 months now, and of course hoping that unicorn will show it head at the right time!, ya know the perfect lathe,regarding size,price,quality ect! As I've had my first mill for almost a year now and about 6wks ago aquired a rare peice to add,a Autometric jig borer, they are few and far between but any input on your choice of benchtop lathe and reasons would be much appreciated, thx!🤟👍🤙
@@coffeytime1979 I got a Grizzly G0602. I probably should have gone a bit smaller to start, but you know how it is. You read a couple different forum threads and suddenly your budget goes from a couple hundred to a couple thousand because it’s a bit better than the cheap ones 😅
Comment
@@hornetf18I have a similar size machine made by warco. You won’t regret buying that machine, it is very capable 🙂
Greetings from a hot afternoon in Thailand. I do all my chores and projects in the cool of the morning and blame the heat for sitting on my arse watching Cutting Edge Engineering videos! Keep up the good work!
People say It's hot this year. It was hot last year. It will be as hot next year. Hi from Pathum thani
Homie and I have the same white muzzle.
Very entertaining! Kurtis' skills in creating new tools and Karen's skill with the camera and production were seriously on show in this vid. Thank you both!
Glad you enjoyed it!
The first thing i do EVERY Friday morning is get up make a cuppa, feed the cat, then sit down and wait for the new video to appear, then Friday can begin!!! Having worked in a toolroom back in the sixties, it jogs my memory. Great skills from the pair of you, not forgetting your lovely pets!! All the best from the UK.
The new split screen and additional measurement information is excellent! Cheers
Thanks for the great feedback! 🥰
THAT WAS AMAZING! I love when Kurtis makes tools in the shop and uses them to work on whatever project he is doing
That boring bar thing blew my mind. I had no idea such black magic existed!
I was wondering what tooling was going to be used to complete this operation ... Beautiful work Kurtis AND Karen . I've probably said this before, but Homeless has to be the happiest pooch on earth . :)
Karen. You are getting wickedly good at the dual cameras and editing!
Thank you, I am always trying to improve 🥰
It's 3am here in Florida and I can't sleep, when your vid pops up. Happy Easter. Cheers
Karen, this one is another marvel of videography. Your use of real time audio with the compressed video starting at 04:00 was so smooth 🤩🥰🤩 And then to both of you, I cannot say how happy your videos make me. Thank you!!
Loved the out-take of Homeless, he's a real character!
2:40 am in NW Florida. Now I can go to sleep! Great job!
That’s the cool thing about being a fully equipped machine shop: need a special one-off custom tool? Just make it yourself. No waiting, and no paying through the nose. 😎
Love the way Karen asks all the right questions to ensure the highest quality content is produced. Eg: "Where does the thing go?". ;-)
Greetings from Boise, Idaho! The "Michelangelo of Machinists" has done it again! Don't have the right tool? Simple. Just make one! See the finished product and remove what doesn't belong! Simple! Karen, I marvel at your video skills. Your close-up work is remarkable. My only worry is getting cooling fluid or swarf all over your lenses! (Or has the Safety Officer made sure that your cameras have safety glasses?) Keep up the great work, you three! Thank you!
I watch several different machining channels, and its always ammusing to me how it feels like NONE of them tap the same way.
It's always interesting when Curtis has to make a tool and shows its process as well as doing the job it was made for
Your real time split screen shots are just awesome. Thanks for including the part location shots. Karen is already a pro videographer. That sweep overhead shot and pull focus in that hole to the thrust face was brilliant..
Friday 8 AM is CEE time in my part of the woods. I wish you a nice weekend from Austria. Cheers!
5 РМ. Привет из России 👋
Cool. Another custom boring bar. It's never boring at CEE.
I’m so invested in these videos, I’m hopeless at anything like what Curtis does but I get a ton of satisfaction from watching !
There is more than one heavy equipment mechanic that owes his job to Kurtis and CEE; your tool making is next level, especially fixing an impossible to repair part. The giant fixture-blocks for mill are cool and your eye-precision / hand work required setting the angle for the insert tooling that sits inside the bar. BTW great finish on the bar, and thanks mentioning the insert. Karen, excellent work. Your split screen edits and interior color grading / exposures are wonderful. Two camera shots using timecode? Your precision is awesome! The hand crank movement lathe drilling was a great idea - Including the spindle slow-down and stop on both splits, no less - are great. The time-lapse dissolve of the finished part at the job's end was really cool. Nice to see footage of Homey and the George the Butcherbird. (in the past - not this video) It would be cool if you had a polarizing filter or second camera set for exterior shots. Its difficult when your pressed for time an running in and out, easy for overexposure, cursing the light and fighting it later. Interesting, your both precise in your own right - yet expressed in different ways. Filming must stressful. His lines, problems with setups camera angles and exposures eat at equipment deadlines - yet it's your wonderful relationship, the love, giggling and laughter which makes the outtakes and channel great to watch - fantastic job as ever CEE!!!
Shop made tools are always a nice present
You guys have really upped your video game. The editing, split screens, voice overs, etc make keep making your videos better and better. And more enjoyable without adversely affecting the technical aspects of the machining / work you do. Great job!
Thanks so much for the positive feedback
I am not a machinist, but I love watching your videos, especially how you make the tools that you need if you don't have them. I'm in awe of your expertise.
Just when I thought there was nothing to watch !!! CEE never lets us down!!!!
It's always a great pleasure to watch two professionals at work...... Karen, you can definitely add sound engineer to your cinematic resume As always Massive Respect from Aotearoa Leave, Same or Better, Everything Be Kind ☮️🙋🏻♂️
I love the sound of quality drills in the morning.
That boring head looks pretty damned handy! Definitely adding one to the list of future purchases
If nobody makes sells or has the tool you need you just make one that is extraordinary. Excellent job thank you for sharing.👍
А так молодец. Настоящий токарь. Сделал державку, и обработал плоскость.👍👌
Loved the ending, he’s such a sweet boy!
I dig the way you guys has been putting/saying the prices of some of the stuff. I understand the not reveling Your prices and such, but have wondered about the prices of some stuff, and the repair vs buy new comparisons.
Thanks for that feedback!
:)
@@CuttingEdgeEngineeringdon't have to be smart to see how economical this fix was, top cee work, go and have some Easter fun
You are of course my favourite engineering channel even if you didn't have the cute birds and that silly Homeless...Happy Easter Bunny!!!
I have watched CEE videos long enough that I had it in my mind that he was going to use the new boring bar like a fly-cutter with X & Y axis movement of the table and Curtis hits me with another new-to-me cool tool in the boring and facing head. I am so used to working with what I have, not what I need. These videos are so satisying and I am addicted!
Gotta love the commitment to make shop made tools to get the job done! Part of the reason I love watching the channel is just that, if Kurtis doesn't have the right tools for the job he will go the extra mile to get the customers machine working again.
Good morning from California's beautiful wine country 😊😊😊 It's been a long week for me. Thank god its is Friday!
Safety officer job is done for the day . Time for a quick sleep. Great engineering to over come a problem. Karen great filming the perfect team.
I was a machinist for 10 years then I was a NC programmer for 30 years. Now retired. Love your channel.
I love the very typical Staffie despondency on being abandoned. How dogs can look sad is a mystery, but they do.
Hello CEE team, greetings from Belgium. Nice work on the planetary carrier, another job well done and an additional tool in the toolbox, a machine-shop without any side projects for getting the job done isn’t a real machine shop. Have a great weekend.
I bet your customer is really happy to get that machine back into production, the time saved is probably worth far more than the part cost. Amazing ingenuity to be able to make that custom tooling from a few scraps, saving yourself and your customers time and money. Amazing work Kurtis. Fantastic videography and editing as always Karen. And wonderful work by the safety officer keeping us all smiling along the way, thanks Homey. ❤
Karen, What a different ending to the video, that is class you guys keep on videoing. D
First rate work, as usual--both in of the camera and behind it! Thanks, guys. Enjoy your long weekend and see you next week. Cheers.
😮 Another good example of how to save money for the customer. Enjoyed the show.
Thanks for watching mate
*Cutting Edge Engineering Australia* Always a pleasure to see another video, thank-you for taking the time to bring us along. GOD Bless.
I love seeing you restoring those good ole CAT parts for new life. I can only imagine how much money you've saved your customers. I bet you are near and dear to their pocket books!!!!!! LOL
The "fuck off train" wall art is mint
Always love some close-up machining action - and credit for the efforts and edited results of the close-ups, slow-motion swarf etc... The focus work and framing, as well as the audio, is simply superb... This channel takes me back to high school and my first experiences of turning and metal work... wish I had stayed in that trade, my Uncle offered me the chance to build dragster parts as he did for some of the top teams back in the day... really wish I had taken him up on that...
Thank you for watching and the positive feedback!
Happy Easter Karl, Kurtis, Karen, Homeless & office mob!
Engineering and photography at its best, thank god you have a wonderful safety officer !
Seriously, this is the best machining videography on youtube. Light, shots, focus, sound, story organization, its all top shelf!
Wow, thanks!
Awesome work, as always) I just caught myself on a though: when Curtiss rides in the hangar on the forklift with some hardware, just wait for it, you'll see some art)))
My friday is now complete!! Blessed Easter guys..
Your use of splitscreen at the beginning was spot on and added a great deal to my enjoyment of the scene.
Helllooo All the way from the Caribbean.. My friday morning video before i sleep
Wow awesome thanks for watching all the way over there!
Love the office sign about trains. 😀 As usual a well set up and performed job Kurtis. I would have been scratching my head for awhile about exactly how to do it even though I have a slightly smaller B & F head.
TLAR = "That Looks About Right". Quite an eye.... :). Another fun video!
thanks for the easter weekend video. We will be spending the holiday with our two adult children and their family’s. eating drinking and just enjoying each others company.
That sounds like a great way to spend Easter weekend! I hope you all have a wonderful time together, Happy Easter!
I like it when you give the value of the replacement for the part you are working on ! as always very good video !
Such great timing of the video. Invariably, every time I think I'll jump ahead a bit, I don't need to see him do this a second time, something is different or Kurtis is explaining something better, and I have to rewind. Great job Karen
My Fridays wouldn't be the same without CEE. love how you're able to adapt with custom tooling to get the job done. Happy Easter guys from W.A
Great video work mounting the camera on the carriage (7:30 mark). It's great to see Kurtis on the lath. A true master.
Hello, I am a turner, my name is Mohsen, I am Iranian, and I follow your work👍
I snuggled up with my little 7 year old tonight and we watched this for a while. He loves this channel.
Watching these operations every week is never ‘boring’ 😉. Then when you make a tool to do an awkward job is like the cherry on top of the icing on top of the cake. Keep up the good work everyone.
Thank you Kurtis for all the great videos. Perfect timing for me getting home from work.
Thank you for sharing your time, I haven't missed a video in a long time, the best tools are your heads, both Karen with the videos and editing (she gets better every day), and Kurtis' work, which there is no word to define something wonderful, my respects from Uruguay.
Wow, thank you for the support and great comment!
Karen: Thank you for including the split screen showing how Kurtis hand cranks the lathe. I really liked the micrometer segments too. Great additions to the video.
Happy Easter to you too, thank you so much for sharing more of your eminent work with us. I almost expected you to be on holiday leave, so this is a pleasant surprise indeed.
Karen, great shot at 27:11 to show the old vs new! AVAGOODWEEGEND!
Как обычно, высочайший уровень профессиональных навыков и отличная съемка, всё понятно даже без перевода. Смотреть вас одно удовольствие 👍
So over the time I've been subscribed and watching your videos, I've gotten inspired to go back to school for machining, metal fab and welding. CEE has been an absolute invaluable resource of info in the form of real-world examples of what I will be looking to do once I graduate. As I watch each video my future tool list keeps growing as well. Cheers from Minnesota, USA!
Happy Easter CEE world…..🌍
Happy Easter
