Repair CAT D9 Bulldozer Yoke | Machining & Welding
HTML-код
- Опубликовано: 13 сен 2024
- This video is a job we did to repair a Blade Lift Yoke off a Caterpillar D9 bulldozer. The yoke is worn out on the bearing surfaces and needs to be repaired. This shows the step by step process of machining down the bearing surfaces and welding new material (we are using ER80S-D2 mig wire) on to the surfaces before finish machining to spec.
In this video we are using:
- Hafco TM-26120G Lathe
- Weldmac WHP-2.5 Power tilt positioner
- WIA 500i Weldmatic welder

I hate it when tools catch a bad case of gravity. R.I.P Turn table
GOING TO COUNT BANANA'S too fall asleep after this video .. or should I count MM'S .. 1MM 2MM 3MM AND SO ON ..lol great video
Where can I grab me a set of those calipers? Are they good enough to measure bananas with?
That’s 5.2546” bananas get it right man! 😂😂😂. Awesome job. Oh I forgot, RIP Welder, poor bastard.
Love the banana caliper. I'll see if they have them on the Snap-On truck when he stops by the shop today. Nice job thanks for sharing it with us.
Cheers,
Bill
You guys kill it every week. Enjoy the content and the interaction in the comments. This is the only RUclips channel I don’t skip through the video. No click baits, adds, promos. You guys never disappoint. Keep on killing it, and go easy on us folk who rely on the banana.
hey mate thanks very much for this comment we appreciate it and the support! Our banana system is growing will be an international unit of measurement soon 🤣👍🍌
You are spot on, skipping is a offence and long live the Banana.
That's exactly what I came here to say. The only content on YT that I watch start to finish without skipping.
@@CuttingEdgeEngineering About the only thing you could improve on these videos is to explain why you are choosing certain inserts etc. I'm not in the trade so it might be nice to have a little 'fact card' or a few bullet points as to why. Oh and more Homeless breaks!
@@CuttingEdgeEngineering I in fact started to introduce the banana unit system in my family... Especially my youngest daughterm who is currently learning the concept of units (metric, of course!) finds measuring things in banana units hilarious! Of course, I us your videos as undeniable proof that this unit is real! :-D
As an American, I loved you throwing shade at imperial measures. Well done!
Love the banana graduated caliper. Whoever made that is clever and a true fan of yours. Great content. I learn new things for my woodworking from watching you machining. My grandpa was a machinist and I have a place in my heart for all doing that work.
OMG, never stop uploading, fridays will never be the same. Bring on the banana's.........
Love the banana calipers. Especially after getting out of a car that has the steering wheel on the wrong side.
The production quality is why this may be the best machining channel on RUclips.
wow thank you
@@CuttingEdgeEngineering I guess add "community engagement" to the list too. Lol.
No music, just the sweet sound of metal being cut, welded, ground...and the occasional squeek of a doggie toy and some laughter. Killing it as usual. Looking forward to seeing that big old keyway cutting monster getting rebuilt!😀
Those Banana Callipers are fantastic they made me laugh so much 😂😂😂
Awesome video again guys great content and an interesting part to repair. I personally can’t believe how much welding has changed since I learned to Arc weld many years ago and never even saw a Mig welder until the middle of the 1980s. Homeless is a gorgeous Staffie and he reminds me of my 2 especially having to be first in and out of the car. Keep up the great work and looking forward to the next video.
I was finally feeling good about my mics and calipers as a hobby machinist, and it took me a long time to get the Starretts and Mitutoyo's that I wanted. Now I see that I don't have top of the line Banana calipers and will always feel second best, I guess this is why I will never be more than a hobby machinist at best.
I think the thing I like best about this channel, is that you are always up to something different...always keeping things interesting...keep on keepin’ on
hey mate we get plenty of the same/repeat work but know that gets boring for viewers so definitely like to keep things interesting and different
@@CuttingEdgeEngineering hi my name is mikhalea and I have a question do you know how view or download RUclips videos that are private deleted or copyrighted even if they are not your own videos if you don't I understand
I have to say I absolutely love your videos! I've been a machinist for 45yrs now, mainly CNC machines and robotics the last 20yrs and I really appreciate your knowledge and attention to detail. You are a very knowledgeable man and have a very nice machine shop!! Also your wife does an excellent job filming all of your content, very professional and makes watching them very realistic. I love when you take a break to open mail and homeless gets a new toy, what a great guy he is. Thanks for a great channel and always look forward to the next video. Oh love the bloopers too!!!!
Greetings from Colorado, USA. I look forward to 12 midnight Thurday because Cutting Edge videos come out. I enjoy the show, but because of Kurtis, I cannot see a banana in a grocery store without thinking about Australia!
hahaa that's awesome glad you enjoy the vids and thanks for watching
No asistí a ninguna universidad, pero si tuve mucho contacto con máquinas pesadas.
He visto varios de tus vídeos.
No manipules el nitrógeno líquido sin protección para tus manos.
Y si tienes que atender otro asunto que te aparte de tu trabajo, apaga la máquina o permite que otra persona la vigile hasta que regreses.
Eres verdaderamente todo un gran tecnico y profesional.
Hay muchas cosas para aprender en tus videos.
Gracias por permitirlo.!!!
CONGRATULATIONS !!!!
Olvidé decirte : hermoso pitbull.
Hace más simpáticos tus vídeos
Hobby shop: This part is way bigger than I usually do, i need special fixture.
Curtis: This part is way smaller than I usually do, I need special fixture.
God I love this channel.

From the other end of the world, The Netherlands, I found your channel last week during a Covid19 quarantaine.
I'm a female sparky, and love the way you talk about your work....
Still looking the episodes back in time, 3 a 4 a day...
Go on....
Jinny..
Hey Jinny welcome to the channel thanks for watching!
Still beating your personal best every week!! Ticks all the boxes.
Educational
Entertaining
Unique
Great work all around as usual. Thanks so much!! 👏
Much appreciated! Karen definitely likes to try and keep the video level high
Your welding and machining knowledge is that of someone that has been doing both jobs for over 50 years. Amazing. Your clients are lucky to have your skillset.
🤣 the banana calipers. Well done! Karen does a great job on the videos too. Just the right mix of 1x and time lapse. All the retakes explaining things are totally worth it too, the videos are really great to watch!
Kurtis you lucky man. Giggles and wiggles have trained you well. That pup is so cute.
That set of recently calibrated calibrator is right on the money. When in doubt, we use chewing gum, bailing wire, and pieces of straw.
Great piece of work from you all !!! Thank you
Calipers
Switching to that ceramic in the beginning made a huge difference. I've said this before but watching such a master at work is very satisfying !
I'm really impressed that the green strapping and the bit of friction the fixture provides is enough to drive the part.
Entertaining and educational as always, well done curtis 👏
Yeah it works well glad you enjoyed it 👍
Yeah, I was expecting him to install as many as can physically fit on the yoke, like a dozen or so. That strap machine puts a lot more tension than I though.
Adds new meaning to sand bagging the part. Worked with a real old guy years ago and some jobs he sand bagged when using a mill.He had about a half dozen bags laying around all the time. 😂I like those ceramic inserts also, use a lot of the ceramic inserts in my work.
I don't know why but I like to watch that kind of stuff. I work in a restaurant but I like to see professional repairs.
Greetings from Poland
Another great one. Karen, the Safety Officer, a weird chunk of steel, a brilliantly simplified explanation of what said chunk of steel is actually good for, flying swarf, welding, more flying swarf. And shiny fresh metal, of course. And outtakes. And so much more! Thanks a lot, CEE, this was fun!
I love the detailed information on welding metallurgy you provided in this video for this specific part. The discussion of hardenability, hydrogen cracking, pre/post weld heat treats etc was all really interesting to see it be applied in a real world scenario. I'd love to see more content where you get into the weeds on the metallurgy side.
And another work of art leaves the workshop. As others have mentioned, who would have thought packing strap could be used as a drive dog. Very lateral approach and one worth storing away for an option. Doubles as a tuning fork muffler. Great stuff.
Thanks as always team for bringing us along for the ride.
Cheers
Pete'.
Hey Pete yeah it works well glad you enjoyed the vid 👍
you make everything
look so easy. having the rite tool makes a diferance
Wanted so much to hear the tuning fork! it must be very rewarding to have other people appreciate all the videos you do.
Good work as always Curtis, the "missus" and homey...
I'm stuck in bed with a stomach bug but binging your videos is making me feel a little better. Thanks!
Awesome relationship between videographer/actor and/or husband/wife. Of the 40 min edited episode, errors or differing opinions do occur. Out takes truly make me laugh for a Friday evening NZ time. Keep up the good work team.
one of the reasons why we only make 1 video per week, for the sake of our relationship and me not being in the dog house 😂😂😂
@@CuttingEdgeEngineering Kurtis, best place in the house is the dog house, get the best grub! Best toys too! 😉
Top shelf stuff! This is more educational then a month in school.
Love that new turn-table and KUDOS for being able to sit still and accurately place your beads for the period of time it took to weld the part out. Anybody that hasn’t done it couldn’t possibly relate to how much pain you can be in trying to sit still and concentrate for that long.
They should've had their "time lapse clock" in the background for that job!
My arm was getting tired resting on the keyboard for the time it took to fast forward through those welds.
Kurtis braced himself for the smaller weld with the pallet on the forks and I kept thinking he must be braced (for the lower weld) and we just can’t see it. Gotta be comfortable if at all possible.
For some reason I really enjoy every time you use the green strapping machine.
After subscribing for many videos I'm so glad you've kept your format of starting with Safety Officer, clear explanation of the part to be repaired, and excellent video recording throughout.
If it was here in the US you'd be Top Bananas!
Well done, many thanks.
Much appreciated
I have 2 cylinders that need rebuilding, too bad he wasn’t in Canada.
I'm totally amazed that the green packing strap had enough friction to drive the shaft like that. I kept expecting to see it stall as the cutting was going on. I had expected you to have to put a dog on the end to engage with the chuck. Bloody amazing. I think I've made this comment before but I'm very impressed with your welding. When you re-cut the bearing surfaces I didn't see even one tiny hole anywhere. That's almost as good as x-raying the weld to look for voids :).
Your problem solving ability is amazing. I am so glad that your subscriber numbers keep going up as your content is always interesting and the videos are edited so well. Thanks!
Thank you very much!
Ive been a tire fitter ,40 years and most of that time Ive been around heavy earth moving equipment , Im no engineer though your vids are educating me .
Thanks for going through and explaining why your are doing ...what you do !
You do very good work. Love watching your show. The endings of the mis takes are wonderful. You're wife's laughing is PRICELESS and Homeless is a mess.
Your videos have taught me enough to change the eyes on my (very small) hydraulic rams. All the way from creating the centering nubs on the shafts to how much to chamfer for welding for maximum penetration!
Awesome mate glad it's helped
I used to work with a larger version of a positioning table. It comes in real handy when welding Sub Arc when you need positioned welds. Because I worked 4/10's this week I get a four day weekend. Time to make good use of it!
Awesome mate enjoy that 4 day weekend 😎👊
The outtakes are amazing!! You’re miss has amazing patience
You sir are a real PRO i enjoy watching your videos and doing repairs on heavy pieces of equipment isn't for everyone , Mrs karen kills it every time with her camera skills giving us always the best angles and slow motion shots , so she deserves a big shout out to her ... Much success to both of you , Greetings for Usa
Hey Jose thanks very much mate we appreciate it! 😎👍
I can’t wait to see what oddity comes to your shop the best thing is you tell us what and where the piece is used. I enjoy watching a master at work. Keep it up.
I never get tired of watching you and your skillful work of art. Thanks Kurtis.
Got my weekly fix of Homie! Thank team CEE!
We use a bicycle tire tube to reduce ringing. Just wrap it around. Loved how your strapping doubled as a drive dog. Once again great skills and knowledge. Nice repair. Great video.
I really enjoy when you discuss the theory - why some types of rod are used, etc. Your experience is clearly deep and wide!
Another CEE professionally reconditioned heavy equipment part ready to go back to work. Always an enjoyable watch, you guys are the best and how all of my Fridays begin! 👍👍👍
Pretty awesome repair. I am amazed how steady your hands were when welding on the new material. Expected some kind of holder for the welding head, but was surprised you did it by hand. Welds turned out great and pretty damn uniform for doing it by hand. Anyway, Thanks for another great video.
I'll second that. VERY steady hand! Nice video, Kurtis! And yes, bananas can take a lifetime to master!
I always like seeing a weld build up being turned into a machine surface, cheers mates!
Great video 👍 I know some of the stuff you do must feel pretty standard to you but to us mortals it’s super interesting and I thank you for taking the time to share and explain 👌👍
Very true! Good to know you enjoyed it
So happy for your successful business brother. Your videos helped get me through my long painful days of Leukemia. Godbless your family and channel.
Love the cushion drive between centres, brilliant set up, fair depth on original induction hardening
Great machining and camera work both 👏 👌.
Thanks for sharing
Being from the USA I loved the banana calipers. Here I was expecting something totally different. Love the videos keep them coming.
I've only participated in one midlife overhaul. It was Not fun.
The "Calibrated Calipers" had rolling. Definitely hilarious.
Love the new welding positioner!
I'm sure it'll make your life easier. You need more of that.
Interesting to see one of these that's actually worn rather than failed. I fix a lot of these for D6Rs. Typically the front bushing wears faster than the rear, and that allows the rear to be held captive while the front half moves slightly. Over time they snap in half on the front edge of the groove for the horseshoe key. Considering what they cost, the contractors are very happy to be able to get the back end replaced rather than buying a new part.
how much do they cost new? These videos always seem like so much work goes into fixing such huge parts that the repair cost would be huge. I can't imagine what the cost is new if they are willing to pay for it though.
@@pudo3792 I think it is more of an issue of availability. The transmission housing that was spray welded in another video just was not available anywhere and had to be produced. I suspect that is the same for this fork as well.
@@stunmunky2 these yokes are readily available but they are ridiculously priced. For a D6R this part from caterpillar (here in Canada) last I heard was $10,400. For a 9R or 9T I'd expect it to be in the neighborhood of $15k. My shop rebuilds them for around $2000 for comparison sake
@@geoffflato6065 Just out of curiosity, does a rebuild include building up bearing surfaces like he did here?
@@shakeydavesr I finish the bearing journals out a bit differently, but yes. At least in my experience even if they are in perfect shape it's just not possible to weld everything back together accurately enough for it to actually fit. No matter how careful you are, it always pulls when welding. And there is only a couple thou of clearance in these fits
Shoutout to your partner doing all the photography. She has a good eye. Well done!
Thank you 🙌
I kind of want to hear what it sounds like without out the strapping. Awesome job you three.
This guy is an artist smaller things are much easier to fix but big ones are real challenge
You three are an incredible team! I love watching such talented folks in action, before and behind the camera. Cheers!
My favourite Machine shop vid, its the dug that swings it..
When I was in school for auto mechanics we had a brake lathe used to turn down rotors and drums and a leather strap to wrap around whatever to stop the god awful ringing
That welding positioning table is a thing of beauty.
Thank you team CEE, great work as always. Superb descriptions/explanations on what is going on, as such your videos would make for exceptional education material. Bonzer viewing.
You prove that a machinist is master of many disciplines, but is also a artist at a shaping material to exacting tolerances.
Ah...the two things that go together are Mother's Milk and cold hard steel!
All the best...enjoy the videos sooo much.
It's 2 am here in Atlanta, Georgia when the videos hit RUclips!
Woah that's a crazy time to be watching!
1am in good ol Oklahoma! 🤣
I am watching this at 1:34am Saturday morning here in Sydney AU. But I am running late on my CEE fix, they published this 14 hours ago (about lunchtime Friday).
It’s good to watch a true machinist and craftsman It gives me faith that there are still folks with god given abilities working with their hands making magnificent items from scratch or just mangled up old parts. Keep doing what you do ,I don’t live far from a cat center that works on those behemoths here in the states
Absolutely awesome. You are an incredibly talented welder Kurtis. All joking aside your work methods and results are pretty incredible. And you make awesome videos with Karen. 🥰😍❤️
👋 Carl welding free hand looks easy when u do it, I have to say at my age my Back got stiff just watching u weld in that position for the amount of time it took. Awesome job you guys rock 🎸
Отличный материал. Как всегда, спасибо команде за то, что взяли нас с собой в поездку.
Hi, Kurtis. I liked the centering tool you made and the damper for the harmonics. Thanks for sharing! Stay Healthy!
hey mate glad you liked that!
I can not belive it! The pallet is actually in one piece!
Great video ( as always ) :D Have a good weekend!
the customer splurged 😂👍
Greetings from Brazil, God bless you all.
Fantastic video, thanks Karren.
The work looked good.
Thanks again!
My pleasure 😊
Another great team effort, thanks, and now looks 10 years younger.
Would be kinda interesting to see how they harden it.
Electric induction hardening would be my guess!
Basically like this, ruclips.net/video/a6YpJXoADCA/видео.html
Actually this one was more informative ruclips.net/video/wOv3i0eoo0Q/видео.html
Always a treat! Love the new positioner, looks like top quality. My back always aches to see Kurtis working so close to the floor!
Now you just know Kurtis will store away the equipment he made just for this one job. Because as soon as he throws it away another job just like this will show up. And we all know he doesn't throw anything away that he think will come in handy.
Great job guys !! A massive tuning fork is right !! This saved your customer a truck load of money not having to buy a new one of these !! Top notch work as always you guys are wonderful !! I love the out takes at the end !! 👍👍
Piękna robota. Wesołe ludzie jesteście, zdrowia.😊
Tak, to bardzo weseli ludzie. I zdolni.
I love it how you try to look so damn serious. The outtakes are great. Thank you. God bless you and your family and aloha
Mate great job, you make it look easy! Not many people can fix the things you do!
A great repair as always👍
It was nice seeing Mark’s yellow stickers, they are truly seen all over the world by now👏
yeah was awesome to get those!
The new positioned is a great addition to your shop. I am always impressed by your attitude expressed at the start of each job, also how well the shop is kept clutter free and equipment kept in working order. The film shots , sound, and editing are also great. Take care of your camera'man' / producer. Makes for a good channel to recommend.
Thank you very much!
love the jobs that come thru shop, I really miss that kinda work, before health problems 👍🏾
Ripping some serious chips :) Quality job- happy customer.
Thanks Lars! Glad you are enjoying the vids
Hello from USA - your work is excellent and inspiring. Thank you for sharing with us!
Sorry to hear about the equipment loss but the new one looks to be a nice upgrade. When you calibrate the yellow caliper do they use "Fruit Loops"?
ahhahahahaha
My goodness the sound that comes off that! You where not joking.
As usual: totally fascinating. I love the new rotator, but while watching you weld using it I wondered if you could not combine your Sir Mechanica line boring/welder with this rotator and automate these sorts of jobs in some way. Bending over like that has got to be hell on your back after a while.
Yup, he will regret it in his older years !! My body is worn out from 40 years of welding !!
The banana caliper cracks me up. So good! This coming from a yank. Great work sir and I appreciate your outstanding work and videos.
Vc é um profissional muito competente gosto de seus vídeos...
Another part has been brought back to life. Nicely done.
Phantastic work!
Offtopic: There is only one thing banana in Australia - you're driving on the wrong side. :)
That's what you think! Ever consider that you might be the bananas driving on the wrong side of the road?
@@markfryer9880 Today, right-hand traffic predominates worldwide. Of the 221 states and territories in the world, 59 currently have left-hand traffic, mainly in former British colonies and dominions with a population of around 2.34 billion.
So 😛
I appreciate the part explanation at the beginning. 👍
No problem 👍
Me when I started watching CEE: "What is that? Why are you doing this? WHAT THE HELL IS GOING ON?!?"
Me after 2 years: "Yes, this could be done on the Mill, but since it's already setup on the lathe, it's more efficient. That's a big piece to Weld, will definitely need to pre-heat it to get the bead to stick. I see the problem, the maintenance wasn't done or was done by numptys"
😂👌 Spot on mate!
Im the same mate, ok thats gonna need a 12mm button bit on there, good to know Im still learning things lol
Its amazing what you can learn from RUclips.
@@ctdieselnut RUclips, well the educational video parts are a great way to show working techniques and points of note for the many trades. In effect it can be like being coached by a top tradesperson, but with the advantage of being able to rewatch key points as they are being learnt.
Homey is one committed safety officer and clearly can't wait to get to work every day, making sure Curtis doesn't screw up.
Great repair. Question; after heat treatment does it need grinding to final dimension? Some materials distort slightly, just wondering.
Same here, I'd like to know!
