Repairing Parts for 2000HP Engine! | Machining & Liquid Nitrogen
HTML-код
- Опубликовано: 18 янв 2023
- We need to repair a pallet of parts for a 2000HP Caterpillar 3516 Diesel Engine. These are some of the exhaust components from the engine that came out of a CAT 789 Haul Truck. The parts are made from cast iron and over time they have worn out. We show the step by step process to repair the exhaust parts including machining in the lathe, boring in the milling machine and shrink fitting new sleeves using Liquid Nitrogen. We're going to give those sleeves a 0.2mm (8 thou) tight interference fit because we definitely don't want them getting out and into the engine!
In this video we are using:
- Hafco TM-1740G Centre Lathe
- Hafco TM-26120G Centre Lathe
- Hafco BM-63VE Milling machine

Shrink fitting with liquid nitrogen is always good fun, makes up for having to machine all these cast iron parts 😅👎 Hope you enjoy the video!

Congratulations on 500k Kurtis, Karen and Homey
That's why when the job gets boring and repetitive it's good to have a "Homey-break"; couple of minutes with Homey and a rubber chicken...suddenly the world is a better place again...well maybe not the world, but a good laugh definitely makes you feel better! It does me! 👍Congratulations again on 500k.
@@Murphyslawfarm thanks for all your support mate, we notice and appreciate it!
@@dennisc3238 hey mate having the doggo in the shop/office definitely makes it enjoyable he's a big lump of happiness. Thanks for your support!
I hate you!, you make it look so damm easy ;)
At 77 years old, I remember as an 8 year old I spent a lot of time across the road from my father’s business watching a real blacksmith in a country town. I get the same enjoyment watching your work. Thanks.
that's awesome mate glad you enjoy the vids!
the ring of a anvil is a sound of its own.
He has a bigger audience than disney. A lot of us are just sick of the constant bullshit and want to get back to basics. A clever young bloke doing a great job, self taught, and kicking goals.
@@paulkeys175 Paul you are a gentleman and a scholar! I think you express our feelings of those of us that hold values and believe in traditions Disney has give us the double barrel butter finger! Sad part is the way Disney got to the point It was until recently was appealing to the family. No More. I'm with you If it's Disney I'm done with it!!
Nothing like watching a skilled craftsman expertly work their craft. Especially one patient enough to let you watch, and maybe throw in a few tips.
Shout out to Mr and Mrs CEE. There’s no other RUclips channel showing such high level machining content. This is a rare insight into a heavy machinery job shop.
Wow, thank you!
Absolutely true Paul!!
What I like about them is that they’re not trying to sell me something that I’m not interested in
@@dirtfarmer7472 yes, it’s unfortunate that Abom has lost his way. He’s now got a showroom full of sponsor’s CNC machines, and he has no idea how to run them…and…he has no more clients.
Ummmm.......id have to heavily disagree....yes this channel is up there but there are many many more whom are at the same level and ABOVE....all over youtube! Are you blind....or have you not looked at all? There quite easy to find also!
I enjoy the “intros” where you explain how the parts fit in the machines, and then the how and why you’ve chosen a particular repair method. Then it makes much more sense when you do the actual repairs.
the knowledge Kurtis has to repair so many different components that cover a myriad of machines is incredibly impressive!
He's by no means unintelligent but I would like to know how much of this information the actually retains versus how much he goes research before each video. That's not to say however that he does not have a wealth of knowledge in his head but there's a lot of small details he provides that leads me to believe he does some researching to make the videos more informative

👊🏻😁🇦🇺🍻🍻🍻
Better get started on casting a brass play button😂
Hey mate! Thanks for that support you know we appreciate it 😎👊🇦🇺
bet so :)🇺🇸
Showing all the machinists channels how it's done! Knocking on Clickspring's door!
@@CuttingEdgeEngineering I say 1- million subs on December 15, 2023, at 1530p.
My insomnia has been in overdrive lately but I have been working through older CEE videos and rewatching more recent ones and for some reason metal work and welding noises have been a huge help in turning off my brain to let me sleep. The only problem is I love watching the videos so much that sometimes I get caught up in watching and it keeps me awake :)
I love this channel so much and I'm so happy to have discovered it.
hey mate we've seen a few comments from others that the videos help their babies go to sleep! Hope you get some rest 👍
@@CuttingEdgeEngineering yea helps my wee man stop crying when his teeth hurtbut ins not like reading a workshop manule for a ford i dosint bore him to sleep hes ingrosed with his dadand his big sister loves to see homless
I so relate to this @Tarpo !
Oh you too? Insomnia sucks!
And yeah, I've been bingewatching these videos too xD
I know exactly what you're going through, there really is something about machining and welding noises that help you sleep
Every video I hear what the issue is and i think "Wow that sounds so specific, that can't have happened much." But like this one, you not only know how to fix it but you have done it before. The wealth of knowledge you all have is very impressive. Great video as always!
Awesome!
I had the pleasure of working with the welders and other professional shipbuilders in the 1980’s as a US Naval submariner. As the first crew to go to sea on the Trident class we all took great pride in our work. I would have been proud to have you work beside us my friend. I enjoy watching your work on every piece of gear you touch! Cheers Mate!
I feel for ya mate. 1/2 million subs and still every move that you make is watched and questioned by the better half. Not only that but she's constantly laughing at your mistakes.
Congrats on the 1/2M. Your channel is bound to keep growing as you edumacate the interweb. Look forward every Friday evening to seeing Kurtis, Homey and giggles' feet.
As a hobby machinist I have learned so many things, and keep learning from your videos every week. Thanks for all you do!
Same here. I have learned a lot about holding the work that I can put to use on my little bitty hobby lathe and mill.
This channel is perfect. We get an explanation of the problem, and the solution. Then we see every step to implement it.
Also we get to play with the dog.
You deserve a lot more than half a million viewers. Congrats on that milestone.
HALF A MILLION, CONGRATULATIONS! THAT DOG HAS A LOT OF FANS. I really enjoy your videos, thanks.
Kurtis. Karen sure makes you sound great at the beginning of every episode. She's a pro editing.
I like the way you explain what you are working on and where the parts go and why the parts go bad, then show how you are going to fix them.
Congratulations on the half a million people who love watching you and Karen and Homeless/Homie.
Huge Congrats on 500,000. The quality of videos that you Karen and Homeless put out are top notch. Eye candy and great content for us wanna be engineers. Onto the episode and cheers to you from Vancouver Island Canada
Thanks heaps mate, pretty funny looking back at the earlier videos, we've come a long way!
Love your home. Family visited Vancouver back in 86 for the Worlds Fair. So very beautiful there.
Curtis, I found another channel a lot like yours. Snowball engineering. He is out of England and works by himself also and he just started the channel. Everyone help him out, seems to be a really good guy.
Mechanical engineer here... I enjoy your practical machining ingenuity a lot! What you do and show here on youtube is a form or art and a huge display of competence! Having daily changing train wrecks thrown at you and just dealing with them.
Karen,
I'm glad you showed us your safety sense when you backed away from the exhaust manifold before Kurtis turned the lathe on. That freaked me out seeing it spin around waiting to hit anything in its path. 😢😭
yeah I did not want to be anywhere near that one spinning 😅
Karen is the real brains behind the operation 🤣
@@glenjamindle They are a complimentary pair. I think Kurtis would be permanently scarred if he had to do the books for the business. 😂
Does my head in as a non hands on the tools guy, is how fine tolerances can be created as a matter of course. It is amazing how fine things can be made up without any 'special' gear. Although do appreciate that the gear isn't cheap, and the skill required to drive it isn't cheap either!
I agree with your thoughts on cast iron, dirty stuff. The reason I enjoy your channel is because I used to so exactly what you're doing for many years. Keep on smiling.
You got all the older Genius player watching you .Keep up the genus playing . Thank you I'm 70 years young love this site.
Happy 500k from your favorite Arkansan college student 🎉
Cheers mate! Crazy to think we hit that many subscribers on here 🤯
With your content and attitude it’s not that crazy
You have the coolest state police ever in Arkansas.
College student huh? That's our good ol' American education system.
@@ThatOldStoner I would assume art school, specializing in collage with a minor in scrapbooking, maybe? 😂 We kid, Eli. Cheers!
This the reason that you don't need to wonder why Kurtis does something 20:06 in any of his videos, there is always an explanation and he gives it. Great video for reaching the half a million mark, thanks guys.
Always quality work from you guys, in both machining and content. You never disappoint. Congrats on 500K! And have fun with the rest of those exhaust parts 😉
Your shit's aight too doh
The sheer amount of wear and tear these parts experience is pretty nuts. The enginuity of the human mind is amazing, but to be able to fix these components is even more incredible. Love the attention to detail and care in the small things. Once again thank you for sharing with us weekly and keep up the good work. I wouldn't be surprised if an engine came in next :
Yes. As he fixes these pieces I can't help but think of them at work routing the exhaust of a 2000hp Diesel engine 16 hours a day, months on end. I imagine the endless heat, stress, and vibration. Yet they handle it because they were made right.
OH Karen the patience you have, the outtakes are great. Kurtis great video as ever and congrats to you both and Homey for 500k. 👍
BTW, What a great service you provide to your customers. I suppose you have one or two competitors, but customers can see how their job gets done to perfection, Kurtis, so these videos really are a credit to you.
Every time I watch your videos, I'm blown away by image quality: The colours, lighting and textures of various metals and tools is a stunning visual feast. (Who knew?)
It was Homie the safety officer pulling her back 😀
Cast iron is one of my least favorite metals to machine.The graphite dust is probably the worst part. I wear a dust mask while machining and cleanup.Another great job,Kurtis
I gotta admit - these heavy machinery repairs are facinating.
I thought my liquid nitrogen anxiety was cured after watching several shrink fits in the clip but then at 31:45 you put me through the alternative test!!!
This was a great video. Thanks.
haha yeah we thought that might make some viewers nervous 😅
@@CuttingEdgeEngineering I like that the bird made it into the final cut because there's no way to do a retake on those shots.
Wow.. you guys achieved 500k subscribers FAST! This clearly speaks to your excellent content and Karen's great work behind the camera. It's nice seeing that there will always be a need for a manual lathe and milling machine in this now CNC machining world.
Congrats!
????
Karen: What the hell?!?
Curtis: I don't know?
Gold!
Even in the shop, the wife finds it! 🤣
Love the outtakes; part & parcel of why I love RUclips. Even channels that do script their content are far more casual & human, often creatively incorporating that humanity in their content.
The example of a marine 3516 you used is actually a pic of my engine room on the tug boat I operate based out of Seattle, Wa sailing back and forth to Alaska! Pretty awesome to see in the vid
Hey Karen, I’m an old retired guy from Canada and I got say as much as Kurtis is absolutely amazing to watch, your camera work is brilliant! Thank you both for all the hours of enjoyment you both provide. (and of course Homeless goes without saying)
I just figured out why I like your videos. Once you get past the explanation and we get to see your workflow, it becomes apparent how many decisions you are making all the time. The confidence in your ability makes it look easy.
Not only do you two possess great talent and mad skills you also have the greatest sense of humor, OMG it’s always so damn funny!
Something very satisfying seeing new metal on old.
Congratulations on the 500k subs! I used to watch Abom79 for heavy machine work, but he's just a playboy now with a bunch of shiny stuff sitting around. You are my #1 go to for heavy machine content and I like the way you guys put this together for video. Please don't fall to the dark side like so many of these creators on here do. I would say you will be close to 1m subs by the end of year if you keep it up. I have repaired some of those exhaust parts like you did there. They were for a D9 Cat and the diffusor where it fit into the turbo had those expansion rings like the ones you were doing. I did the sleeving like you made up for your repair and it worked nicely. Keep up the good work and we'll see you on the next one!
Good to see people are finding the handsdown best engineering channel on you tube, i need CAT bolts for my milling clamp set too
Good to know that sleeving these is an accepted option. I have a few cast iron bits and was considering building them up with braze, but this is much, much easier.
Congrats on the 500k!!! Here's hoping for another 500k in this year!
Nice explantation of proper rebuilding of a used part. Also, editing is very dynamic on this, shows multiple perspectives, weaves the story together nicely.
Congratulations on the 500k subscriber, love your channel and what you do - Its not a sponsored tool show, its real parts and problems getting done.
All the best for the future!
Thanks heaps mate we appreciate it! When we started the channel we wanted to it be real work in a real workshop. Good to know that's coming across in our videos 😎👊
I used to work for Deimler/MTU/Detroit Diesel for 25 years(until 2018). Alot of the large MTU marine engines(and smaller truck engines) had steel rings that you could replace for a better seal. I'm surprise CAT still uses that interference fit like that. Thats what older Detroits used years ago when I was just starting out in the 90s(the engines were from the 70 and 80s)
The 3516 is quite an old engine - it began production 1996 or before. the 35xx and 34xx series predate the current C-series.
@Keit Hammleter The first 3500 series engine rolled off the line in 1981. Fundamentally, it hasn't changed much. The fuel system has been the biggest change.
They were using steel insert rings on some of those turbo discharge tubes even back in the 60's. Some engines got them, some didn't.
@@typrus6377 the 3500 and 3400 series were my absolute favorites when i worked at CAT many moons ago. I in-framed more 3500's in tugs then i care to remember. The 3500 was just so epic in its simplicity. And they just freakin RAN. Forever.
@@keithammleter3824 yeah I'm not saying that it's not an old engine. I'm saying that after all this time nothing has been improved on the engine
@Patrick Gordon I still work on both series on occasion. The 3500 may be old and simple, but there is a reason that it hasn't hardly changed. Same for the 3400- the C15 is basically a 3406. The C18 is basically a 3456. The C27 is basically a 3412. The C32 is basically analogous to the C18 vs C15, just V12. All 4 still installed in brand new machines, EPG, Pumps, etc. If it weren't for the Aftertreatment hoo-hah, they'd last as long if not longer than the old 3406E.
Gday, congratulations on 500k, how awesome is that, this was a really interesting job, I’ve had manifold sections on Detroits over the years that were completely rooted and leaked more out the joins then the stack, this would have been a perfect fix, we couldn’t get new ones at the time, awesome video as always mate, have a great weekend, cheers
It was a very interesting job
Cheers mate thanks for your support pretty much been with us since the beginning! Yeah pretty simple fix for something that is quite common on these sorts of engines. Hope that spidey bite heals up quick for you Matty! Cheers chat soon
@@Murphyslawfarm howdy Murphy I hope all is going good for you.
Production values have increased since I last watched one of your videos, good job 😊
Your narrative over the Timelapse is just right good explanation of the project. Good video
Great show mate. Keep it coming. I'm not a machinist specialist like you. I'm a hobbyist welder. I love watching your show. Thank you
All impressive stuff! An innate ability to engineer things! It’s in you matey! I did 20 years of very varied engineering from miniature, to things weighing a ton or two! I liked the challenge, as you must! It’s a satisfaction to a relative few, who can do! I enjoy your methodology, utilising so many skill sets and equipment knowledge! No empty vessel to be found here people! Well done all round ! Cheers
Hey, in the Outtakes you have for the first time a smile :-) in your face , that makes you much more sympathetic in the front o the camera ..
People are telling me for 35 years now , "Hey german, put a smile on your Face " and it works !🙂🙃
😀and by the way , love your vids , I am a Fitter and Turner by Passion, keep on going !
You are definitely a Master Machinist. Impressive work.
Congrats on 500,000! I bet you never imagined such a level of success and interest in machinist work. You have a great team! Take care....
Always fun to watch the Master at work on Fridays! I did feel cheated with the outtakes last week, but this week made up for it. Great job again all three of you!
Karen has come up with an important new innovation in machine shop videos with the split screen shots. Absolutely love them!
I usually watch RUclips on my phone in bed but today I put it up on the 76" tv with fancy speakers and the video looks and sounds awesome!
Can't believe I missed this first time around. It's just in time: a friend is using these techniques, I help
Thanks for all the great content guys you both rock 🤟 much love from 🇨🇦
Thanks for watching! We appreciate it!
always interesting how cast iron throws different chips
Cast iron is basically large grains of iron stuck together so when machining it mostly comes off as grains popped out of the surface.
The reason you folks reached a half million (and now onwards to a million) is because you both are so talented in your field of work that compliment the two. Don't tell Homeless but I think he could have his own very successful RUclips channel.👍
Many people have never seen a small block V-8 and here is 4-turbo diesel. 2000hp. The shrink sleeve was great to see. I think the Most Spoilt Dog is the smallest thing come in the doors of your shop. And the cutest.
Another master class! Awesome effort as always. Many thanks K, K & H 👍
Ahoj,pěkná práce, a jsem rád že máte i české titulky, člověk ví o čem je řeč. Zdravím z české republiky
I believe this was one of your better ones , cast iron exhaust parts machined with steel sleeves . Thank You .
Congratulations again on 1/2 million! So nice to see some work being done, unlike other channels making a multi-part video for no reason. Watched one recently that took 30 minutes to put a chuck in evaporust… Keep up the fantastic work Kurtis and Karen. All the best from the UK
You two guys are a pleasure to watch. Your machine work is outstanding, and Karen's video work makes every video very educational.
I often find myself thinking about these videos days after watching them.
How does one keep from falling asleep wen watching this channel? the sounds from the tooling and machines running is just so soothing......
I once tried to install one of those engines in a Chevy Nova ...
Back in reality, I was quite impressed with this refurbishment.
Another job done well! Your knowledge is amazing for a young guy! Your technical talent is only second to the superb camera work and editing!
Curtis, You make this look like child's play, my friend. Another excellent video displaying your incredible skills. Thank you, Mate!!
Heard the bird and I thought George had brought the kids 'round to see Gramma and Gramps... realized quickly it was a crow. Ah well, you can't depend on kids these days to visit when they should!
After the shrink-fitted sleeves, this engine can be repaired next time with just cutting off the old sleeves and putting new on... something Cat should've caught when this engine series came online about 1980. But this way, Cat sells more expensive parts, I guess.
It's good to see that Homie has definite ideas about where his squeeking chicken should be.
Thanks for explaining what you do; too many people try to keep it a secret, that only they know. There's a difference between having the secret, and being able to execute it, and you have the execution of these secrets down to an art form. Thanks for filming it, and congratulations on 500K subs! The channel deserves it!
All the explanations by Curtis shows his massive knowledge of the machines for which the parts are for as well.
500k, congrats! 👍keep it up, it's great and almost mesmerizing to watch your machining! and your explanations make it very accessible, even for a woodworking guy.. 😁
Wow 500k. Well done guys, well deserved. Thanks for the great videos, its what Fridays were made for :p - Have a great weekend o/
Thanks so much!
I don't know why I find this stuff so incredibly fascinating! You are a natural born teacher........and then I saw the out takes. Lol 😳 🤦♂️ 🤭
Been with you from the start mate. You think your doing engineering, I think your doing therapy for us all. Thanks K’s.
Congratulations on your subscriber numbers; well deserved because you and Karen do a remarkable job every week. I love the out takes, which highlight Karen’s patience. Best Regards
Awesome stuff as usual! You've earned your following with hard work and great respect for your audience and your craft. So happy to see the channel keep growing, it's been an amazing couple of years 😊
Nice work Kurtis ,We used to throw these manifolds in the scrap bin when they fretted out , great to see them getting a new lease of life keep making great videos mate it’s what Friday’s are for cheers Mate .
I like the format that you have chosen for video content. The entrance of the work, Kurtis' explaining of the job and parts. Karen's cinematography. Homeless, George when available. And the outtakes. Both of your personalities are the topper of the whole project. Thank you both for your hard work.
Congrats on the 500k mark here on YT, absolutely well deserved to you both for great content. Wish you all 3 best of health and fortunes and look forward to enjoying more videos in the future. Greetings from Denmark
I’ve said it before would love to work with you. Your pride you take in your work rivals mine. I just hope RUclips always stays secondary to actually doing the work you do. I would much rather have one Friday video of the quality that they are over a video everyday!
hey mate thanks for the feedback! We want to keep our channel as real as possible, our business/customers are our priority and I think that makes for something unique with our channel, we don't want to turn into just a content creator or product promoter 👍
Worked for a company back in 2007 that used to buy those Cat engines in the natural gas version for gas compressors. They were a million US dollars apiece and did not give discounts for multiple buys at one time!! Oh, shipping was extra. Thanks for sharing!! Ken
Primo video again guys, congratulations on the 1/2 mil. Your editing is on point Karen. Machining is ok as well.
haha cheers mate!
It is a testament to your work and confidence in your ability that your customer would send additional components before receiving the first batch back ⚡️👍
I have a complaint about your videos !!! , they are addictive. They are a great way of getting through a cold wet day in N Ireland. A true master at work.
I just enjoy watching you old memories come back also I'm seeing tooling and machines I didn't have in my days. I started my apprenticeship in the 1950s I'll be 81 in March 23
Another good video with different parts just to keep us entertained. Congrats on the 500k. You have earned it. Thanks for sharing
Thanks for another great vid - and congrats again on the 500,000 subs 🎆✨🎆
Great slow-mo of the boring bar in action - kind of makes it worth the cast iron clean up 😃
All the best,
Paul
Karen's just got a new phone/camera so she's hoping to take the videoing and close up/slow mo to a whole new level soon
A perfect engineered solution to correct a poor exhaust connection, a quality repair job, that'll pass a close inspection. Great video and another excellent professional repair.👍😏🇬🇧
The boggling fact that you're a one man show producing high quality work blows my mind. I tip my hat sir
Hi Kurtis...congrats on the 500K. Your content is consistently interesting. With such a wide range of jobs, is there a "standard" way of doing each job or do you have to plan each job considering what you need to achieve? The range of processes is amazing.
there's definitely a plan for each job, even a part that's the same as one I've already done could throw a curve ball and need a different setup or repair.
Great new topic and congratulations to you three on 500k, really well done.
Thank you so much 😀
@@CuttingEdgeEngineering For 1M world needs to hear f off train,f off plane ,f off bird montage song.
I just started learning to machine a little over 6 months ago! I found your channel and I've learned SO MUCH about machining from you and your channel that helps me out at my job here in the states!! I would give anything to be able to come and apprentice under you just to learn everything that you know!
I love your channel..... keep up the great work friend!
So nice the customer cleaned the castings before sending. Congratulations 0.5M subscribers!! Glad to be one of them…

I really appreciate the explanations about what the parts are, where they come from and what your diagnosis is before the machining starts. Many other channels just start somewhere and jump into the machining.
.2 interference sounds hard to do with just a fire extinguisher in the bush. I/we never I am still finding posts from you two after all this time. I blame it on RUclips not advertising the ones we used to get notice of in our emails. Refits like this will likely be the last these pieces will ever need as long as they are aware they do need a bit of care being the 2 different metals involved. A dialectic grease on assembling will help that situation for thousands of hours in that application. I admit the piston ring seal is a good idea initianaly but I see they have had the two metals bind with each other and just plain not a long term repair. My hat's off to the one that thought about making that happen.Kudo's to your Karen for the great footage and editing. You two have a video nailed.
I had an artist come into my corner in the shop wanting the long, endless chips like these. It was weeks later she came in and showed me a mountain setting, framed picture with the various coils. One day she stopped coming and of course I didn't have one of her pieces. She had them sandwiched between glas panes so they wouldn't cut every finger they encountered. She was a master at getting them apart in the barrel. Take care you two, I hope this week is a winner for both of you.
Great work as always sir, trust a machinist to improve in 1 day what CAT engineers probably took months to design!!.. did anyone else's heart skip when the first sleave you heated didn't just drop onto the manifold 😂
Karen's heart skipped a few beats 😅
@@CuttingEdgeEngineering She has faith in your abilities ♥️💕♥️
It looks like someone under-charged and is paying the reward. Work is work though, thank you guys for a informative and entertaining video once again. Have a great weekend.
* Yeah, well done for the 500,000 subscribers. Onwards and upwards, superb work Karen, Kurtis, Homie and George.
hey mate yeah probably didn't charge enough but we'd rather make a little bit a lot than a lot just once
@@CuttingEdgeEngineering Always best to have work coming in that people going elsewhere. Have a tinny for me. :)
@@CuttingEdgeEngineering or, as I was taught when I was young, “You can shear a sheep many, many times but you can kill him only once.”
When the first heated sleeve didn't go on right away, I gasped... Of course, you were still cool and made it work.
Been watching you (and Karen) for quite sometime. Couldn't get the piston to go into the bore of a caliper on a vintage motorcycle I'm restoring. I watched one of your vids where you used liquid nitrogen. I didn't have liquid nitrogen laying around of course, but instead put the piston in the freezer overnight and piston dropped right in. Works as it's supposed to. Thanks for showing us!
