Repair FAILED Hydraulic Cylinder | Part 1 | Making a New Barrel
ฝัง
- เผยแพร่เมื่อ 7 เม.ย. 2022
- This hydraulic cylinder failure is one of the WORST we have seen lately! The piston and seals are completely destroyed and the inside of the cylinder barrel is shredded from one end to the other. This is the stick cylinder off a Komatsu PC300 Excavator, it is a high cycle cylinder that gets a lot of use, so when things fail they can turn bad really quickly. The reason this hydraulic cylinder has failed is due to a number of reasons but it all started from the bad design of the OEM piston seals. The cast iron pressure seals are not a good idea! This video is Part 1 where we show step by step of making the new barrel. We need to remove the barrel end and head flange off the old barrel and machine up the new barrel. We also fit and weld on the ends to the new barrel using spray transfer MIG welding.

I really laughed hard at the Alle-key scene!
Hi Kurtis! Do you ever feed back your findings to the manufacturers? As an ex Komatsu(Mining) employee I can certainly attest to their quest for quality.
@@dermozart80 glad you found that amusing 🥴😂
@@Churchill250267 hey mate nah, not sure they would appreciate the feedback I have to give 😂
@@CuttingEdgeEngineering You're probably as diplomatic as I am, then... Great video, as always!
"At my own cost, I'm going to do this to make it look right: - and THAT, girls and boys, is called Pride of Workmanship. Nice one, Kurtis.
thanks mate
Absolutely. Cheers.
My dad used to say, right is right & wrong is nobody’s right
Plus it took off something like 24kg per meter of barrel length if I didn't totally mess up my math.
I was taught and have stuck with it the last 40 years " like it grew there".
At this point these Videos should be used as a teaching aid for students learning this trade in class. Outstanding production values and presentation! If you never made another video your body of work thus far cannot be overestimated for it's contribution to promoting the Millwright and industrial machining professions.
hey mate we've actually had a few trade schools reach out and ask to use the videos! 👍
@@CuttingEdgeEngineering Hope you made deal your skill is required learning!!!!
@@CuttingEdgeEngineering Hope you edited these for swearing? Don't want to give the yoof any bad habits now do we?????? Might scar the poor little darlings for life! Lol.
Or mechanical engineering of how not to design a cylinder.
Actually, what trade is it?
This video is documented proof that professionalism isnt the words you say, its the standards you practice. Cant stop binge watching these!
Express your distaste and do a hell of a job anyways. Commendable.
Re: turning the barrel at your own expense: one of the things that keeps me coming back to this channel is the pride you take in quality work. Very well done.
everyone should take pride and have top notch quality like kurtis. sad to see that alot of ppl just dont care that much.
@@hannesblomqvist6954 to make people care... they have to be paid..right now machinist and other trades are one of the most underpaid out there
I’m amazed at your skills. What would a repair of this extent cost the customer?
@sikkingtruth7488 you can pay to the moon, if a person doesn't give a damn, money won't make them care any more. Giving a damn and going the extra comes from inside. They either have it or they don't.
There’s a lot of things to like about this channel, but an under appreciated one is The Giggler’s dedication to a strict upload schedule. That can’t be easy. Keep up the great work you two.
Thank you for noticing I appreciate that and at times it's not easy can definitely create some stress 😩🥴👍 Karen😁

This is absolutely masterful. While this may be another day in the life for you, it's a rare pleasure to see something large done so thoroughly and professionally with zero bullshit and helpful commentary. My experience is limited to what I did in metalwork in school on the lathe. This for me is genuinely terrific to see. Thank you kindly from Dublin. The outtakes are up there with Jackie Chans! :D

These videos are an absolute masterclass. Your work is superb and the videos are great to watch, even for someone only vicariously interested in machining. It's always a pleasure to watch a master at work!
Your Technical Skills and Your commitment to “Total Integrity” to do the right thing for your customer! Looking forward to “Part-2” (also: nice clean shaving)…..
Cheers mate thanks for watching 😎👍
@Simon Sapot Thanks for the reminder.😂.
I think I will never get tired of seeing shavings spiral off the cutting head. It is like watching a fire. Thanks to Mrs. CEE for her great cinematography and filmmaking.
Glad it was enjoyed 😁
The pride you take in the work you do is second to none. The mindset of "If I were the customer, how would I want it to look?" Speaks volumes about how you run your business. I'm beyond impressed Kurtis. Your costumers are fortunate to have you doing their repair work. Kudos to you my friend. 😁👍
Agreed - new tech but old school values.That's a winning combination. Good on ya, Kurtis.
Your a standup guy doing quality work. If I were a customer, I wouldn't expect or allow you to eat the cost of making it look right. I hope that your customers know what kind of person you are. It's rare to find someone who cares so much about the work they turn out.
I’m glad none of these companies do preventative maintenance. Otherwise we wouldn’t have these killer videos.
haha this is true
@@CuttingEdgeEngineering We used to call these kind of jobs 'cash for life' jobs.
I always etimate that in my shop 80% of failures are caused. Only 20% is because of stuff being worn out or failed from natural causes.
For a short while I worked for a heavy equipment manufacturer. Our very expensive machines (Also very manitenance-heavy) needed some frame repair on-site due to abuse, but we sent an engineer and a technician to do the job. The jobsite secured a welding machine per our instruction, but literally had no other tools. None. They lifted the cab off the machine with rope they found at the local village. They found a breaker bar and a large adjustable wrench to do the rest of the disassembly. How you can buy a bunch of heavy mining equipment and not have a maintenance truck is beyond my comprehension. I don't even think they had tools to do oil changes. 😕
I think this situation was big $5M worth of machines and pay local peasants to drive them. Get paid $10M for job completion, and abandon all the machinery in the remote village.
Makes me feel really good to see an honest, hard-working professional doing the right thing every time. I appreciate you and your work. Thanks man.
Cheers mate thanks for watching 😎👍
1.7 million views absolutely amazing, I just love your processes and the clever skilled way you go about your work.
Coming from a life time helping design and installation of the electrical parts of machinery but would love to know who is watching you both with such enthusiasm of your skills??👍😁
Cheers mate! Viewers are from every part of the globe it feels like lol
@@CuttingEdgeEngineering I hope you’re receiving funds fm TH-cam as are other Australians like LaVagabond etc if not would be worth contacting them you would be in the top Australians views wise👍😁
it never ceases to amaze me how he runs that giant machine shop all by himself such big equipment he's got to be one of a very very few machine shops that are equipped with that kind of capability quite amazed excellent work my friend
When I was an equipment mechanic I'd use a stethoscope and listen to the hydraulic cylinders and predict the next one to fail. I'd mark them by stamping my initials into the barrel by a pressure port. When machines would come in with metal in the hydraulic oil the yard guys would look for my stamp to know which cylinder to pull. My boss hated it because I was right so often. 🤣
haha that's brilliant
note to self: Add a stethoscope to my field toolbox...
@@Hyratel if you do not have one in your pocket grab hard wood stick. Pressed against object of interest and base of your ear works well to transfer thing internal sounds to your hearing aparatus
I used that technique to check roller and ball bearings. It also worked on bearing problems in the Diesel Engines used in the river boats when I was on a repair ship in Vietnam in '66-'67. Better to pull an engine before it failed and left a boat up shits creek with only one paddle.
It is incredible that the lack of maintenance, and the replacement of a filter of no more than 100 dollars, produces the catastrophic deterioration that I have seen today. Great job guys!! Greetings from Argentina
Nah they are a chunk more than that, but compared to the cost of repairing... well replacing this cylender its absolutely nothing in comparison, especially when every other cyl in the machine, plus the hydraulic motors for slew and drive are probably going to need the same treatment before long... also maybe the pump... OH and the valves
The filter's just there to protect the pump and stop circulation of crap in the system, once that thing started galling up there was no saving it.... All but the most attentive operators just run their machines until they break.
Bosses don't care about preventative maintenance cos they don't see the advantage, why take a running machine out of service? That costs them money.
Problem is they end up spending more when the inevitable catastrophic failure happens........ so it's a double edged sword.
@@LuggageStardate I have to thank you for the answers, since I am ignorant in this matter and I am only subscribed because of the admiration that Kurtis causes me for his skill in what he does. For me his work is art, perhaps for others it is something normal.
I appreciate his comments because they help me understand a little more about the causes of these damages. A special greeting from Argentina, from an admirer of Kurtis who doesn't know how to put a nail in the wall!!
@@nickmaclachlan5178 Thank You Nick, I agree with you
Repairs sent out are a tax write off, in shop just overhead.
An absolute joy to watch you work. Your expertise is exhibited in your clear and concise narration of what you are doing and why you are doing it. Great to see someone who knows his craft and is as humble as you.
Well Kurtis, an ABSOLUTE masterclass in problem solving! With your skill and experience, do manufacturers actually listen to what you say?? Always look forward to friday and your latest revelations. I have learned ALOT by watching your videos and long may it continue nate!! Wilk have to visit your merch page!!
haha nah don't think they would like what I have to say
@@CuttingEdgeEngineering Such as that thread-lock on the piston head. Like... WTF was that
@@CuttingEdgeEngineering Btw, greetings from Brazil. I might be the oddest viewer you may have hahaha. Im a biologist, and I just finished my Master's in pathophysiology. But my hobby is metal and wood working on the weekends haha. One of my dreams is to have a shop that is 5% of what you have. I find very interesting watching your videos, and as Tarkers65 said, the problem solving. I LOVE to watch someone with experience do things that for me were unimaginable. And not only having the right tools, but the right approach. Btw, amazing collection of tools you have my friend.
Anyways... An outstanding machinist who is teaching a biologist across the world how to approach things in a more efficient and inteligent way.
HOW DID I FORGET ??
I need to say that I fucking LOVE your dog
One of the things I've most enjoyed watching and working with true professionals is the economy of motion they use to preform their tasks. You are a joy to watch Curtis! The absolute minimum of wasted motion, your obvious planning your motions three steps ahead, your getting the maximum benefit from you lifting aids. It's like a master class in great body mechanics.
I'm thinking of the 'economy of words' in the post above.- (making do with less) - bravo!
Curtis, I've watched a lot of your videos and each one your dedication in what you do astounds me. No shortcuts taken and proper pre-planning of each operation is clear to see. The motto measure twice and cut once probably sums up everything you do. You and your better half are a joy to watch and listen to - keep it up!
both of you do a masterful job in presenting this work, and demonstrating the best way to provide full "customer satisfaction". I really enjoy your work and the videos you produce.
3:00 am in Atlanta, Georgia...worth getting up to watch!
All that damage is incredible!
Love the video and great photography.
Dang mate that's dedication! Thanks for taking time to watch hope you enjoy it
5:10 AM here in Atlanta for me! 🤣
Yes, our Aussie Bloke is a hero of engineering. ;-) A very welded-on follower of these wonderful Aussies, bloke (engineer) & blokette (film-maker). Not in my city BTW.
I love how the new barrel is wrapped in "Fragile" packing tape as if its not a tube of 1" wall thickness steel lol
It's so refreshing to watch and listen to a guy that absolutely knows his stuff inside out. Top notch work Curtis!!
When all the movies out lately suck I watch CEE and am never disappointed. My inner childhood fascination with machines comes out. I become awe stricken by the amount of precision and care taken in this profession. keep up the good work
That ceiling hoist has well and truly paid for itself I'd say, a well set up work shop Kurtis! Great work Karen, the video work competes with any professional channel on TH-cam
A few other things on the wish list for the shop for it to be setup how I would really like. and Karen says THANKS!
Hi from Canada's East coast 4:00AM here. This one was well worth getting up early for. Kurtis your Knowledge and experience make these vids so educational. should be required viewing for operators and maintenance people everywhere. The operator of this machine should be sacked! no excuse for allowing this to get this bad. looking forward to part 2
Hey Mike seriously big thanks for taking time to watch so early! Glad you enjoyed it 😎👊
I actually just noticed that the steel from the shavings got to the point where they turned into "Blued steel" due to the heat. Always liked the look of blued steel, so it was a little interesting to see that happening right before my eyes!
You have a very impressive skill set! I love listening to you explain what you are doing, and why you are doing it that way. Also, your thoughts on why the failure occurred is very interesting. You pull no punches in what you think, which is a sign of a good teacher. I can tell that not only do you sincerely love what you do, but that you take immense pride in your work! It shows. If I were a customer, I would not think twice about recommending you. Although you might cost more, your work is going to perform and last! Fantastic video! *Compliments to your videographer and editor!* 1st class content!
Oh man, was looking forward to this! This looks properly destroyed.
😎👍 enjoy
@@CuttingEdgeEngineering After listening to your analysis of the design of the piston I was really looking forward to the end part for what you really thought of it. Was not disappointed 😌
I shudder to think about what the rest of the hydraulic system looks like if it doesn't have a filter! 🤮

Absolutely f*cking munted. 😀
"That's a little Mitsubishi that's a little Ford" you had me rolling on the floor! Much respect Kurtis keep up the excellent work.
The camera work is outstanding. Kudos to the camera person.
Dear Kurtis, I love the fact that your primary drive is to make your jobs look “right” rather than get them out of the door quickly. If only all manufacturers had the same attitude, the world would be a better place. Thanks.

Could not say it better!! Nice work Curtis always a pleasure to watch your videos. Keep up the the good work!
Love the look on your face when you said "NO, not doing this" -> i think that proud workmanship get you a lot of customers! Well done sir!
That's the mark of a REAL professional. Sometimes you just have to swallow the cost and time of unplanned extra work. Reputation-building, customer service and taking a long-term view of business. Downside is that you're going to get MORE of those epically-munted cylinders to fix! 10/10 for the blooper reel.
The sound of all that gravel in the piston would have been lovely to hear in operation
Hey Guys, thanks for another outstanding video! The production and editing is spot-on. If Kurtis ever got tired of machining and fabricating, he could be a first-rate instructor if he wanted! Especially liked the discussion about the manufacturer's design faults. I hope the manufacturer takes his advice to heart instead of sending a cease-and-desist letter. Greetings from the US, where that sort of thing happens all too often!
What amazes me is the fact that Curt keeps in mind that he tries to make a happy satisfied customer and Curt is doing most of his work keeping the cost to the customer at a reasonable price! Customers reply to the job provided is the best advice one caan expect for future repair jobs if required. Love all his work and good luck to him and her!
Great job on the graphics, Karen! Very pro looking. Well done!
I always love watching y'all's videos while I'm at work. They help to keep me motivated while I'm drafting plans for our cladding projects.
Thanks so much!
I'd say that's probably the world's fanciest cylinder barrel that large, being nearly 100% machined on all surfaces like that. 😂

Glad you enjoyed it!
It's amazing that the chrome on the rod is not damaged.
When I first read the video's title, I thought it said the "REPAIR FAILED, hydraulic cylinder, Part 1...." and thought "oh, boy, this ought to be good!!" As it turned out, it was just another job well done for Curtis. Love this series of vids, sir.
Nice job,
I’ve been doing this for 35 years, you do an excellent job explaining.
I’ve seen this same scenario many times, it’s hard to tell once the damage is so extensive. Normally this starts from contamination in the system and every stroke just makes it worse as you see. The cast iron piston rings are used normally when the piston passes over the port, although harder than the Teflon piston seal it’s still a good bearing surface against the honed tube. The unfortunate thing is that now all that metal is everywhere in the system, including most likely all the cylinders, valves, track motors ,rotary swivel and hoses.
One thing also to consider is the oil might have broke down in the heat and lost lubricity and started the whole process as well.again great job on your repair, it’s nice to see someone who knows how to do the job the right way.
All the way from Louisiana USA. Love your content and might I say what a slick ass shop. Keep up the good work.
Cheers Sam thanks for watching over there
Wow Kurtis how the hell could you not hear that happening on the machine, it must have been squealing like a banshee. Great informative video as always thanks to you both, oh and Karl. 👍
yeah they would have heard it and a good operator would have felt it
Between the sound of the engine, the hydraulic pump, the radio, the heater/AC, the bucket scraping on rocks, the other machinery around, not to mention the squealing, ungreased pins and I'm not surprised they didn't hear it.

Hey Curtis, serious question mate: Why don't you elevate the welding rotisserie so you can stand at a comfortable height when you weld eyes on barrels, etc?
I think sometimes it's easier to sit on the floor to weld. Is for me anyways and your body is steadier too.
@@LawF250 Interesting. Thanks. He's certainly holding a fixed position for a long time during that operation.
I have the same thougt. And why not build a simple stand (seen one i personal) that holds the torch and weld by it "self" maby you activate the torch switch by a foot operated pedal?
@@fulf Sure - the lineboring welds are automated.
@from the dark side of the moon I'm interested in the reason he does it that way. Certainly he could elevate it if he wanted to.
“That’s really a shit design.” 😂 oh the honesty. How many engineers have messed up something by making it over complicated. Thank you to those engineers that make things better.
Great video as always. And incredible camera work as usual 🤗
The engineers/designers were probably told by management to 'Find a solution that doesn't look like company XYZ's design, we don't want to be hit by a IP theft charge".
@@rgmolpus Maybe, usually it goes like this “that cost to much, find a cheaper way”.

Hey Roger! So it must be only 2 hours ahead there now? Good time to be watching hope you enjoy this one 👍
Same here, Central Otago NZ
Hey CEE! Halfway through the video I already see several things I love. As usual. #1 the "yelling" at crap design and maintenance procedures... the world needs so much more of this. #2 the water through the anti-vibration bar around 24:25... a bit messy with water fwipping around outside but I can see it helps controls shaving/particles as well as keeping the piece cool. Awesome! #3 Your camera+production "crew" continues to be amazing. #4 (best for last?) You continue to be amazing. Thanks for another great video!
Hands down the best machinist on this planet, great work curt. I wanna be like you when I grow up, says me at 34 lol 😂😂😂😂
I've seen wheel bearing failures with less material than that. Incredible. 😳😳
yeah this one was a good effort
G'day! from the USA! Totally 'Munted" is a frikken understatement. I know you are up to the repair.The explanation behind the damage is perfect. The only thing I find questionable is running over the electric cord/welding/air hose at 26:05, learned a long time ago about the failure possiblity. Loyal weekly subscriber!
Cheers mate! Always good to see your comments 😎👊
You are amazing.. You do what I call investigative repairs.. The opening of the hydraulic filter is a great way to start.. I wish I would of known this 55 years ago. We had a 966 Cat we used to contract plow snow with.. One of the rams got weak. We had it repaired and then kept changing the filters plus initial all new oil.. This worked but eventually another bucket ram started to get weak. We should of had all the rams inspected for contamination initially. But the big brute ran well after that and 5 years later my dad sold it. It seems that excavators just get abused.. I been watching on ic weld for the last few years …the many things the get broken on excavators. Great channel.... Well mate I like the coin jar too. I just can’t stop watch you repair things.. Great for old man to do …than watch anything on tv..Your out takes on this video are right on too.. Thanks..
My goodness you are saving your customers so much freaking money. They're essentially getting an OEM replacement part at a fraction of the cost. Very cool work you do.
Brilliant as always guys . I'd say that was definitely mullered, good job they got you re manufacturing a new one . And careful or your gonna fill that swear jar in 1 blooper out take . Cheers guys
Absolutely terrific video, as usual! Kurtis, you are such a stickler for perfection, as you showed by machining the complete barrel to make that cylinder look correct, to fit the tube mounts.
Videography amazing, Karen. Love the slow-motion of machining chips flying! Swear jar gonna be full, soon😂
Hey mate! Yeah I have pretty high standards and been made even more aware of it over the years of fixing other peoples fuck ups 🤣
Amen to that!
When I saw that swear jar and it's fancy lid I thought there might be a speaker in it - drop a coin in and it would say "Thankyou" or "Good one" or "Scrooge" or ..... wait a minute! Just had a brainwave! I'm going out to my cave!!
Been binge watching y'all for a few episodes. Meticulous and exacting work! Well done. I'm sure nobody will read this but I thought the swear jar was going to say swear words when you put the coins in. Cheers.
Nice work! Love the details and explanation of each step! Keep up the great work!
Curtis you’re a walking machine shop. Mad respect. I worked in super precision for centerline for years. It’s a whole different animal. Making things under 2”. You my friend are an amazing engineer! Btw have you ever checked out KT3406E before? I thought you might get a kick out of the content.
Trying to imagine what a complete re-plumbing job on a machine of that size would entail....clearly it would cost an absolute flaming fortune.
Generally, the hardest part is removing hydraulic tank and getting it clean. Of course, removing the operating spools and spool; blocks, cleaning and checking them is a F****** horrible job. (it's fitted and plumbed before a lot of parts are assembled when machine is being built in factory) When I moved from 'workshop' fitter to 'Site Service Engineer' I made sure all the filters were checked instead of getting things sent back to workshop as I knew I would probably do a better job 'on site' than some of the people I was working with were capable of in a workshop. When a 'temporary' on site repair is still being hired out 2 years later it shows the 'quality' of work shop charge-hand was doing. I have no idea how he ever kept his job?
Amazing! I know a little bit about machining, and engineering in general. I had no idea a shop could do repairs this large and complex. I would have assumed it would require factory replacement. Great stuff.
I'm really impressed very professionally undertaken
Another fantastic job by the man, the myth, the legend! :) This has to be one of your best videos, Kurtis! Looking forward to part @!
Out of curiosity....are you self taught, or did you attend any kind of engineering school for what you do? My guess is self taught. :) Cheers from Alberta, Canada!
Hey mate thanks for watching glad you enjoyed it. Yeah mostly self taught and then went through the trade school used RPLs to get certified
