Cylinder Disassembly & Repair for D8 Dozer | Machining & Welding
This video is a job we did to disassemble and repair a D8 Bulldozer hydraulic cylinder. This is the blade lift cylinder on the bulldozer and the rod is damaged and needs to be replaced. This shows the step by step process to disassemble and tear-down the cylinder, make the new cylinder rod and then re-assemble the cylinder. First we use our 150T Hydraulic Press to help with the disassembly and tear-down the cylinder. We machine up the new cylinder rod using a 3” inch diameter induction hardened chrome bar. We need to machine both ends of the cylinder rod, the first end we machine and cut internal threads to suit the piston & bolt. Then we machine the other end of the rod to weld prep by machining a bevel and drilling a hole for the eye spigot. The eye is welded on using metal cored wire and because the customer wants the rod to look as standard as possible we set it back up in the lathe and machine down the weld. We finish it off by installing a new seal kit and re-assembling the hydraulic cylinder in our press.
In this video we are using:
- Hafco TM-26120G Centre Lathe
- WIA 500i Weldmatic welder
- Metalmaster HPM-150T Hydraulic press

So the world is short of good rods glad I love holes then 😂😂🤣🤣😂😂🤣🤣😂😂
@Mr. Avuncular G'day Oregon
@Mr. Avuncular loving it, ordered some more tool holders it's a keeper!
Возьми меня к себе на работу
How can you bend the rod but keep the cylinder straight? ....
The best part of the repair was the barrel wiping tool: A length of PVC pipe with a towel duct taped onto the end! What are the two main tools of a man's repair kit? Duct tape: If it moves and it shouldn't. And WD40: If it should move and it won't.
heck yeah mate that's how we roll 😎👍 thank you to Karen for the donation of the towel LOL
@kentuckyken keep your stick on the ice.
I also use duct tape for things that are stuck! Do you ever get tiny metal slivers in your fingers? I do, so I push my fingers against Gorilla tape and it removes dirt at first, even in the grooves of finger prints, and then I can see the slivers and usually the adhesive removes them. Sometimes it takes a few tries and angles, but the slivers are so small that it is hard to get them with tweezers and often times the duct tape is closer.
I would enjoy an extended "Blooper Video"... something that could be looped at night before bed.
The way the smoke wraps around the rod as you’re threading looks really cool!
Lovely "that's not a wrench..." moment at the beginning! 😂 Great job as ever, folks.
Being retired, I sometimes forget what day it is. Your Friday videos reset my memory. And they're informative and educational. Then there's good ole Homie. Not to mention the bloopers...
Thanks for watching each week. Karen might just do a mid week video soon to mess up your days of the week 🤣
Amen...I have th3 same problem...I need a calendar not a watch
the same boat😀
Another great job Curtis although it has to be said Karen's editing makes you look so smooth and professional. Really enjoy these, keep up the great content guys.
She agrees 😂 and thanks for watching mate glad you enjoy it
I think it's Kurtis that makes him look smooth and professional 😉
Behind every good man , is a great woman, teamwork and hardwork also count for much, great job, congratulations.
Totally agree these presentations are totally professional.
@@pbysome Let's just say Kurtis makes it look professional, and Karen makes it look smooth 😀
As a machinery mechanic, I appreciate all the explaining. I love the learning that I am doing by watching your videos….Thanks
I'm no machine shop operator and do sort of know one end of a spanner from a screwdriver. But with watching these videos I'm starting to recognise the different tasks that need to be done and have started to say to myself "i bet that he'll do %thing% next". Sure enough, 90% of the time i guess it correctly, so I think I'm learning a little here, which I am quite happy about.
Most of your videos should be required viewing for machining and welding classes in either high school or colleges. The way you break things down into readily-understood terms and provide context for what you're doing would be invaluable for newcomers in the engineering fields. It's probably one more reason your customers come back: if you can honestly and clearly explain how why you're going to do a job a certain way, they'll be more understanding and less reluctant to agree to the cost. That in itself is a valuable 'soft skill' to possess and goes a long way to keeping your business viable. A tip of all the hats to you and yours.
cheers mate thanks for sharing your thoughts!
Our american't skools...are falling way short on teaching the fundimentals And mechanica
Mechanicals Required by todays standards...In the early 60's i had printing , woodworking, metal shop and electrical. Plus 4 semesters of technical drawing...pencil. pen and ink on velom sheet... all now lost in time... Shame is on skool bored unions not parents.
The amount of stuff I've learned about random heavy machinery from these videos is awesome, such great content
Glad you like them! More to come!
Just unbelievable the professionalism and extensive knowledge you have. I bet you’re a damn good operator too. Also the filming and editing is perfectly done. Some may say the stars have aligned for you two. But in my opinion it’s hard work, intelligence and determination.
thanks very much with both appreciate the comment!
i would add a serious Attention To Detail and serious Pride In Workmanship
I don't know why I like watching your videos. I have been an aircraft machinist for over 40 years so you'd think videos of machining and repairs would be the last thing I'd want to watch. It's probably because the majority of my time has been as a CNC production machinist. A glorified button pusher. Never did this kind of work.
I assume Kurtis reciting his wedding vows was quite entertaining. :-)
It is always reassuring when CEE videos begin with the company Safety Inspector doing his rounds.
I love how you say they are capable while still bringing you work, that’s a real man right there everyone. Take notes all you ‘nobody can do my job’ men, you could actually learn something here.
Glad to see the FSO wearing his hy-viz vest. And says C. Dundee, “That’s not a tool post, THIS IS A TOOL POST!”
I love the totally normal table drawer/chest full of cleaning liquid.
Getting a "whole new rod" sounds like a nice upgrade for someone with a bend in theirs.
We agree! 👌
When you know how to use the bend properly it could be a selling point ;)
@@grotevin Selling it to measure Bananas
A bend is ok. If it starts weeping fluid, then you need to see a professional.
One of my favorite things about your videos is how, when you rig heavy parts to move them around, you always seem to find the perfect center of gravity such that the part hangs level and true. Either you have a great eye for the balance point, or the Mrs. is good with editing! Love the content, both of you. I teach science in the States, and regularly show your videos to my students as an example of science in the trades. (Not the outtakes, of course! Lol) Many thanks for making these videos. -Dave B
Hey Dave, i've had enough experience rigging & lifting these parts to get balance point pretty much every time. Thanks for showing some of the content to your students that's awesome. Cheers 😎👍
Just found your site. While reading the comments discovered Dave B same as my name! Couldn’t believe the skills you have! It would take a lifetime to learn them. Oh, I’m a retired public school teacher- D Butler, Circle A Ranches, south Texas, USA

Why do I like watching this more than a talkshow? I'm on the other side of the world, you sleep when I watch. :)
I love that you guys are making longer videos. I never get tired of watching your videos. I've watched every single one 2 or 3 times each to pacify me while I'm waiting for the next video. I'm addicted to you channel! =-)This one is really cool. Different than what we're used to watching. Kurtis' job is cool AF! Always something different and he gets to use different tools all the time. Love you guys and I especially love Homie! I want to hug him so bad!
hey mate, welcome to the #CEEAddicts club where just 1 video isn't enough 😂 Glad to know you enjoy the content!
Two exemplary craftspeople at work: Curtis's machining and Karen's videography! Your content is so good that it invariably ruins the next day for me, since I can't help but to immediately watch your videos when I get a notification that a new one has posted - which means I am up until 4 am here in the States!
Hey mate comments like this are really encouraging for us to keep making these videos, it's awesome to know the videos are enjoyed that much. Cheers! 😎👍
@@CuttingEdgeEngineering - You're welcome, but the pleasure is all ours. Wishing you, Karen, and Homie the best from Cleveland, OH, USA!!
notification squad, Have a nice weekend!🔥🔥🔥
Hey mate! Notifications working well 😎👌
Here in Canada, I repair cars for a living and am inspired by the way you guys fix and fabricate heavy equipment. While at work, I often am reminded of how you approach problems and systematically deal with one issue at a time until the job is done. In the end, the work is as good as new, if not a bit better. Your attitudes and commitment (in front of and behind the camera) in the work you do is refreshing and a pleasure to witness. Keep up the great content and I wish you both the greatest of success in your endeavors.
I am an amateur, very amateur, machinist. I watch you to get ideas on how to do things in my little shop. I could watch other channels and get some of that knowledge, but those channels don’t have Homey.
awesome mate thanks for watching glad you can get some tips and tricks!
Friday always brings a joy with these wonderful videos. I love the meticulous and methodical approach you use to rebuild these rods and cylinders. Seeing the fit of that spigot is really satisfying. Thanks, too, Karen for the excellent videography! This is my last day in the rehab clinic. I came in here in a wheelchair four weeks ago and yesterday was able to walk 3 km without help. It has been a struggle, but definitely worth it. I'm grateful for the excellent medical and therapeutic help I received.
Praise God for your healing! May He comfort and strengthen you in the days ahead.
Hey mate glad to here your recovery is progressing, sounds like you have been in good hands there. Hope you continue to feel better Bruce. Take care!
Great job Kurtis. I work to with a lathe an milling machine in Portugal, and I like see our vídeos. Very good vídeos! Greetings from Portugal
Awesome mate thanks for watching, respect to you!
What manufacture is your lathe? I always like hearing which manufactures are in a country.
@@ShainAndrews I have a lathe shop and I make and repair machine parts, cars, motorcycles, boats, etc. Go to my channel and watch my videos. Greetings from Portugal kzhead.info
Thanks very much for the Entertainment we appreciate what you do. You your girlfriend and that lovely little dog.
Kurt/Karen you folks ROCK, Homey is Awesome as well! Stay safe, Stay Healthy, most importantly stay FREE! Saying Hello from Florida USA.
Thanks mate hope you're doing well over there
HI ! Having tat dedicated cyl tie down bench is such a blessing. Those big nuts were almost impossible to break loose. I remember a feller buncher boom cyl that we had in the 50 T press with a 12 foot snipe and 10 of us bouncing on it and only managed to break 2 standard 3 1/2 inch regular sockets. We ended sending it to the town north of us to break down. I eventually made our own V groove piece I could move in and out as I needed. I never really tire of watching you do what you do so well. Seeing the chips form and fall away was a big part of my life now gone. Thanks for bringing back sooooo many great memories of days long passed my friend. Take care eh.
Really enjoyed hearing what each seal did, I've never heard it all explained individually as people usually just refer to lot as the seal kit. Great stuff as usual.
Thanks for the comment glad you enjoyed it!
i really enjoy watching your vids. Burnt out at work and booked off about to lose my salary and not job opportunities for engineers where i live. The joy of making things and watching people make things makes me feel happy, one of the few things that still make me feel that way.
Hey mate you know what the say, when things are looking down only way to go is up. Glad you enjoy watching our vids you take care
Homeless lifts my spirit every time! You're a champ Homey!
I'm waiting for the "Out takes" video. Make it a drinking game, every time Curtis says "right on" you take a drink..
I can't believe how professional she makes you seem with the edit. The reality comes at the end! No judgement, I curse and yell my tools too. It's part of the process.
lol yeah the "real" workshop comes out at the end, would be good to leave it all but Karen is worried about youtube strikes 😂
@@CuttingEdgeEngineering reminder: April 1st is a Friday coming up VERY soon, and perfect timing for a "true" shop video, with the bowdlerizing at the end.
@@CuttingEdgeEngineering you should do an uncut video, leave it unlisted, and post the link in the comments lol I don't know if they will still strike it, but less likely to!
@@ke6gwf Good idea, and someone filming Karen filming Kurtis.
Just a tip for using the big impact. When trying to loosen a tight bolt if you manually hold the socket in the direction of travel the impact blows are more likely to transfer more energy to the fastener instead of letting the socket loosely bounce around and not efficiently transfer the impact energy to the bolt. Thanks for all the tips you share, I thought I'd share a tip from Canada.
That makes sense cause you are taking up the slack.
When the dugga dugga dugga isn't enough threaten it with the gas wrench.
Sir, you are a master craftsman. I was a machinist a long time ago. You should be very proud of your work and professionalism
You are the Man!!Cheers from Toronto Canada!!
Your hard work and drive for success is truly admirable. Keep up the hard work and all the best in the year ahead!
Thanks mate appreciate it!
Kurtis so glad to see that even someone with your skills sometimes misplaces stuff, makes me feel much better about myself 😀
Great content mate! A shit ton of great information for everyone around the globe! Heavy equipment rebuild and repair takes more knowledge than anyone really understands. Keep up the great work!
as always an exceptional job
I am always amazed at what Kurtis can do. He makes it seem so easy. The videography and editing play a big part in making this one of the best channels on KZhead. Oh and the comic relief from the safety officer doesn't hurt either. Keep on truckin guys. Cheers from Giddings, Texas..........
Another fascinating vid guys. Great production as always. Have to say the (lack of) runout on those chucks never ceases to impress / amaze me.
I know enough about mechanical stuff to know I don't know $hit. I marvel at the depth of knowledge and experience it takes to do what you do. And the fact that you two take the time to show us how you do it... I'm sure the filming and explaining costs time (and time is money), so you're giving all of us something of real value by making these videos. Thank you.
Blimey!! There's a whole Seal Colony in that cylinder!!
Awesome timing, I was just looking for a video to put on to fall asleep to!
Sweet dreams 🤣👍
I can remember vey clearly watching my father doing a very similar procedure, this was over 60 years ago, a very nostalgic experience watching your videos.
that's pretty amazing, always interesting to know if the videos bring back memories for viewers
Can't wait for the large walnut, but that big cherry should be interesting
I've been a machinist/toolmaker for 37 years and just watch this for the dog.
😂👍
Kurtis makes it look so easy, is professional and informative, then at the end, you show all the problems that Carl has, great work keep it going.
I love watching machinists work. I never know what your up to until I've watched the entire video and it's always a pleasure watching em turn out real good.
Brings back great memories.
Another job done. And done right. You two ROCK!
Another Friday has come Curtis, Giggler and homeless are back at it again, life can't get any better. Cheers to you all, hope your feet are drying out.
Much dryer here now thankfully! Enjoy the video 😎👍
You always make these incredible jobs look SO SIMPLE. Thanks for another great video!
3:30 That got a laugh. That's some serious torque.
1:24 thank you Kurtis for supporting my country at this difficult time. Subtle, but I spotted
1 of the few channels where I Click the like button "Before" I watch! Great content for so Many reasons! Thanks for the Entertainment! Cheers ♥
Hey mate that's awesome we appreciate that support!
I am in awe of the depth of your knowledge and the skill of your editor. I am continually impressed by the level of professionalism on this channel. Please do no stop making videos!
Thanks very much!
love that new lathe tool holder !
Once again, it's cool to see our products in application, our shop makes the molds that produce many of the SKF and CAT wear bands and seals I see you use.
Another good job mate. Well done. Karen is good at editing to make you look good mate. And homeless is doing a good job keeping you all safe. Good work and thank you
Not too close unless it touches eh? Another great video guys, love what you do and glad you share it for others to see, thank you
Well done Curtis, as usual! Your friday video is always a good relax and top intersting moment, when a war is going on 1000 Km above our head and CoVid19 pandemia still alive between us. Greetings from Italy. Go on!!! Mauro
Love the improvised giant cotton bud used the clean the cylinder out.
I love your passion for the work and videos! It's clear that talking to the camera isn't always easy, but I appreciate that you keep on at it!
Thank you both again for the fantastic content, it's always a good day when the notification pops up to say there's a new CEE video available! I love that Kurtis explains the components and their functions as well as the process involved in the repair. I have zero engineering knowledge but am truly fascinated by what you do and thoroughly enjoy watching your videos. Keep up the good work!!
Hello, Thank you for showing all you skills, my father (1919-1999) worked on a lathe for 30 years, I came along too late to see him at the machine. I know know much more of what he did thanks to you.
Thanks Karen for the shorts of Homie. Looks like the grass is growing in Australia. We are at the end of our winter here. Great job Kurtis
Your channel has become my absolute favorite! I look forward to Friday when you post a new video. Kurtis-I really appreciate your explanations of each job, what your going to do, and why- you’re concise and to the point. Watching you work is an education. Karen- I agree with all the comments, great filming and editing! And Homeless- keep up the good work!
Hey James thanks for the great comment mate, it's awesome to know when a viewer enjoys the content and channel that much and we appreciate the support. Cheers 😎👍👍👍
I start my Friday mornings with Kurtis and Karen. There is something very relaxing about watching the chips fly. And you make each job seem very easy. Anyway thanks much, stay safe and best regards!
Cheers mate thanks for taking time to watch
Hi mate Im Shane the more and more I watch of you doing those jobs, The more more I Think I should have got more into the machining part of my fitting trade. Im an ex serviceman Navy Marine Technician (Stoker). Yes, I did my trade in the Navy, left, and moved into the minning industry for 12 years. Well done, enjoy your channel.
I was expecting Homeless to have the D8 Dozer Cylinder in his mouth, not a toy.
He is loving the pineapple! Won't even drop it for a treat 🥴
The three of you make a great team. :-)
thanks mate!
Best part is, no "experts" commenting and negatively criticizing your videos. You know what you are doing, greetings from Texas, USA.
Cheers mate! We appreciate our viewers and community for the great support, armchair experts or keyboard warriors are always welcome to have a go 😂👍
Nice job Kurtis! Be safe!! God Bless!!
Nice work. I've got a tech here at Texarkana that does the same thing with my worn out, bent, or broken cylinders for my old Ford 4500 backhoe. Very important to get done right and quick so the machine can get back to work. I really enjoyed seeing the process done right. Stay safe.
Right on mate, sounds like you've got a good tech there 👍
Bardzo jest świetna ta robota i elegancki pomysł i uwielbiam ten film i ten cały kanał pozdrawiam twórcę tego filmiku mile i serdecznie 👍👍👍👍
Enjoying your videos here in Kentucky. You three are the best.
Watching you work and fabricate things makes me look at the guys in the shop that work for my company and think " how on earth can you get so many thing wrong with so many resources? And how haven't you been fired?"
Another great educational vid from 'Downunda' ! There must be a reason, but I would have a bench of some sort to weld eyes with the weld rotator. Thanks again from the USA.
hey mate thanks for watching, yeah a welding bench to fit the size of the cylinders we do just don't have the space for it, these rotators can get put away with no space lost. We do have plans for a welding lathe project in the future 😎👍
They must have boiled a big rock up over the blade to bend that ram like that .There was a lot of life left on that trunnion gauging by the stack of shims on the cap . Thanks for sharing .
yeah not sure the back story, the customer got the machine 2nd hand and was giving it new life
Very instructive. You folks put out wonderful product as well as educating. Thanks for the look!
1056 plantations away 🤣 as a Melbournian I can confirm this 😉
I just recently came across your channel and I've watched two of your videos so far and both have been great to watch. I'm a welder by trade and although I'm not a machinist I've worked along side a few good ones. You are a triple threat in the repair business for sure. Knowledge and skill for mechanical, machining and welding aspects for whatever job comes in. Looks like you have an awesome shop too. Based on other comments, seems like your wife does all the camera work and she does a great job as well. Both of you stay safe and God bless.
Interesting to watch & a good job done, Editing was spot-on with good close ups, well done to you both 👍
Brilliant thanks for the comment
You took a rod eye off with your bare hands! So strong!
Another great video Kurtis and Karen !
Thanks again!
Gostei do seu serviço, muito cuidadoso em sua execução, muito técnico, com todas as explicações e um serviço bem limpo. Parabéns!
Q - How much torque on that piston retaining bolt Curtis? A- All of it! Loving the level of detail you went into on the explanations here mate, thank you - great vid.
All the ones I’ve seen have been torqued by god lol
@@RainOnThursday If Curtis weighs 80kg and the pipe+wrench are ~2 meters then 1100+ ft-lbs
It’s a pleasure watching a great craftsman at work. Your welding skills are amazing…!
Well, I said when I got my tax return I'd buy some merch. I just ordered me a nice hand made leather wallet from the shop and it should be arriving here in Texas sometime in the coming days or weeks. I'll post up a picture once I get it. Thank you for all the great videos.
Once again, a wonderful Friday night's relax with a beer with great content from Kurtis, Homeless and Giggles, the wonderful camera operator. Just one question, who does the editing of these videos? Cheers from Auckland, NZ :)
Hey mate thanks for taking time to watch and comment. Karen does all of the editing 👍
That's not a pipe wrench, THIS is a pipe wrench.
Nice job Curtis 👏👍
You make it seem so easy, yet still attention to all the details. Great job
When you cut internal threads, do you cut a run-out groove at the end or just watch the DRO to know when to disengage the half nuts . Just thought that I would ask a pro. Of course, nice machining and video as usual. Thanks.
hey mate I watch the DRO and disengage at the same spot each time
@@CuttingEdgeEngineering I think cutting a run-out groove is well worth the time. With the watch-the-DRO approach you will disengage *close* to the same spot each time, of course, but as the thread cutting tool is at deeper cuts: cutting for just a smidge longer means the cutting tool is suddenly encountering a lot of material at once. And then, even if you would be able to disengage at exactly the same spot each time, stopping the spindle while still cutting is hard on the tool anyway. Finally, with a groove where the thread will end there is the option of mounting the thread cutting tool upside down, running the spindle in reverse, cutting from left to right. As Joe Pieczynski puts it: that removes the pucker factor.
@@cleon_teunissen I don't see him breaking many tools and I don't see him puckering either, threading to an undercut is a good method so is watching the dro, I've seen people turn the last bit by hand crank, whatever works for the individual mate and it looks to me that watching the dro works for him.😀
Thanks for the vid - Friday can start now 😁 Just wondering what wonder material the pineapple is made from - it has survived Homey for several weeks!! 😃 All the best, Paul
not sure, it's a Sugelary Squaky pineapple dog toy, high-quality food grade rubber is what the ad says 😂🍍
Love shop-made tool; the mop! To clean out the cylinder! PVC pipe, Duct tape, and a rag! That's engineering! : )
might have to patent that one 😂👍
@@CuttingEdgeEngineering right! Lol
Thanks Kurt! Have a nice weekend!
