Repair DAMAGED Hydraulic Cylinder Barrels | Hitachi Zaxis 670 Excavator Part 2

This video is part 2 of a job to replace the hydraulic cylinder boom lift barrel and pistons off a Hitachi Zaxis 670 Excavator. Something has failed or made its way inside the cylinder and absolutely destroyed the pistons and scratched up the inside of the barrels, so we need to make 2 new pistons and replace the barrels! This part 2 shows the step by step process of repairing the damaged hydraulic cylinder barrels. We are starting with the old barrels and machining off the barrel eye and head flange. We then machine up the new barrel before fitting and welding the eye and head flange onto the new barrel to complete the job.

My dad was a machinist for over 60 years, I watched him parting off cylinder heads one time...He literally set the machine, sat on a chair and took a nap. the minute it made the sound it reached the ID, he snapped awake and grabbed the lever. He did this 8 times in a row...That's how you recognize a machinist that's got TONS of years of experience. He could recognize any sound on the machine just by walking next to it, and he used to tell the younger guys how to fix it. He worked for a aviation manufacturer and could machine parts done to the millionth of an inch on a lathe that was built in the 1940s. I'll never forget that.

Near the end when you said, "let's see how fast we can get this lined out", then showed you picking the barrel off the pallet, I expected you to go out of frame, then cut to immediately coming back in with the finished barrel. But that worked too. You showed all of the detail on the first one, then the big picture on the second one. I have never seen you method of wrapping the strap around the fork. My guess is that is to keep it from slipping. I also caught where you marked the strap position after setting it on the lathe. Little things like that save time and possible problems. You are right about the anxiety level when installing bushings with liquid nitrogen. Clean, check, double check, plan your moves, practice your moves, check for tools handy, have plan in place for if things don't go right. Then DEEP breath and go for it.

It's a first class operation from the videoing, to the editing, to helping Kurtis give his professional narration of how and why he approaches each job, always with the client's need to get their equipment repaired quickly and expertly and back into service ASAP, and the video presentation of Kurt's encyclopedic knowledge of repair work in action, his ability to make any tools or accessories he needs, and his ability to acquire and utilize pre-owned high-quality machinery that enables him to take on and complete jobs that require having those tools available to meet his client's needs. Notice that he respects the privacy of the name and work location of each client, and uses generic pictures of machines he works on, to help viewers understand what he is doing and the importance of a proper repair to the future trouble-free operation of each piece of equipment he works on. And all under the watchful eye of his Safety Director, who apparently thrives on a steady diet of plastic creatures not found in nature on this planet. Thanks guys, for showing the world how this type of work can be accomplished with precision and speed, if you have the knowledge required for the work, the drive to make your business succeed, the perfect location for getting it done, and marry a highly skilled videographer and editor who can show people what you do and the money your clients likely save by hiring you to solve problems that dealers and others aren't able to deal with effectively or in a way that helps clients keep equipment essential to their businesses running continually.

My dad was a machinist, he never taught me one thing but I watched him in our home machine shop to turn, weld, and to watch him repair things. He died when I was 12 years. I still remember the smells of burning cutting oil, welding rods burning, and the sound of the lathe turning and the sound of the cutting tools against the different metals. Later in life, I became a Quality Engineer for GE doing tests on copper and steel and brazing with GAS and also Induction heating tools. I also like the big equipment repairs. I was fascinated with large road equipment as a kid. Thanks to you and your wife for the channel. The doggy is precious and keeps me looking for more. The only bad part I remember is my dad and grandad were outside welding a frame for a dump mixer. They said don't watch, so I got back a distance and watched from the tree. I went to bed that night and my eyes were welder burned, mom put raw potato mash on my eyes. I hope the Doggie does not look at the welding.

"so I can see the puff of smoke of hydraulic fluid" 5) Getting the heavy flange stuck on the floor!! 6) Explanation of the size of the heat crush / expand machining dimension, 7) Welding heat shrink, and what you had to do to fix that. Gotta suck getting surprised by stuff like that, but it does show how hard your work is. 8) Explanation of why you didn't use the big honing machine to fix the end. "Won't fit in the machine, and can't do 1/2 and 1/2. Won't line up and be parallel." As always, keep up the good work, and I can't wait to see the next one.

I’ve been machining manual lathe,mill , programming cnc and running one off parts of all kinds for nearly 30years . And I’m impressed. I’ve seen so many “hacks” in my days and it’s refreshing to watch another pro at work! And the editing of course , she’s top notch as well . Lastly my daughters want your dog 😂 . You sharing him with us makes it a nice way to share a sat morning.

Where to start, the incredible machining that Curtis makes it look easy or the amazing filmography, editing is on another level! Amazed by the iPhone, but I believe a more pro camera needs to enter the scene.

I couldn't help but laugh as you were trying to lift that end piece of the floor😂😂😂 Surely the customer has half a brain to know that the supply chain had failed, which meant that you were not to blame for the delay???

[@CuttingEdgeEngineering]

that bloody flange practically superglued itself to the floor I tell ya! yeah unfortunately we were given a time frame by the other shop boring & honing that we allowed for, which was not met and very frustrating for us and the customer

[@garymurt9112]

It's a chain thing. Head guy is yelling at the one under him, then he's yelling at the one under him, and so on till it gets to you. Most upper management is just looking at numbers on paper and typically had to pay for their intelligence (my name for most college educated people). But when you have a machine sitting there not doing anything it's not making money and machines like that tend to make 1000 thousands an hour.

awesome mate thanks for the great comment

Really good work Kurtis. It must be extremely satisfying for your customers that they can see what they are paying for when they get quality work done with you.

The best part is that you could paint the cylinders literally any colour you like and the customer would still be happy to see them.

Bottom line the costumer got his hydraulic rams back no fault on your part. Finished to CEE standards. You must be happy it was just two rams. The filming and editing is as silk. Homeless proudly shows off his latest toy. Team CEE the best engineering 💯👍

Not once have I seen a cutting corners from you. As always, cheers mates! Give homeless a scratch and have a wonderful weekend! Sincerely, Rob

Speaking of stress levels going through the stratosphere, I can totally relate! Been there, done that! I reluctantly drove big rigs for many years (nearly 2 decades) and frequently I'd be told that if I'm late on that load, I'm fired. Couldn't sleep, couldn't go to the bathroom, couldn't do anything but drive - sometimes for days on end. I think prison camp would have been far more enjoyable. Anyway, I can relate. High stress is no fun! :)

[@AquaPeet]

So your superior is literally telling you to break the law and safety regulations or you'll be fired... that's..... awesome. Be safe man! Enough drivers fell asleep during a long haul...

[@Fireclaws10]

@@artmckay6704 sucks about your back man. Everyone talks about why young people aren’t getting trade jobs, it’s cos i’ve seen the result. You end up getting paid better at the start, then after 20-30 years your body is fucked, and you can’t even properly enjoy retirement. And you still need to work another 5-10 years after before you can retire with a broken body. Not for me. The boss doesn’t care about you. Don’t want to be in a job where someone else can sacrifice my physical wellbeing for their bottom line.

[@artmckay6704]

@@Fireclaws10 yup, guard your health and don't sacrifice it for anyone if you can avoid that. I was trapped in an area without much in the way of jobs and I had family I had to care for. Many of the older drivers I met were out on the road to take care of a family member at home. I think the best option (but risky) is to pick a business you enjoy and find some way to work for yourself. Risky as it is, at least you can enjoy going to work and you have the possibility of doing well but there's no guarantees....

An excellent 2 part video series Kurtis. Nice work on scoring those tubes too. Would you believe we are also struggling to get material (BMS) for the school workshop. It’s getting ridiculous 🤦‍♂️. Thanks for showing your method, not many people share their “Trade Secrets”. It’s great teaching an old dog new tricks 😉. Hope you’re all doing well up there?

The editing awesome job !! Kurt you are an incredible machinist the job was completed with so much professionalism. I know there is more behind what's show in the video, but over all the job was completed, customer is happy that's what's matters. Take care now thanks 😊

[@hydroman99]

From Winnipeg, I agree with your decision to rebarrel. I have also seen extreme honing leave a horrible taper at the deep end of the cylinder which leaves a guy with the choice to run with a terribly undersized piston or risk a proper sized piston getting stuck in said taper. Keep up with the great content and you'll have a million subs in no time.

Kurtis, you do some things the way you do because you're a god damn good professional machinist with ton of experience and high skills for solving the problems. And there's no need for justifying your modus operandi. This week's is "professor Kurtis explains; and somehow roast all the keyboard warriors". Educational aspect of your videos is priceless. And it's filmed perfectly.

[@CuttingEdgeEngineering]

haha cheers mate!

[@kellyblack4897]

As a former CNC machinist who came up from Brown and Sharpe single Odd, I enjoyed when you explained the lack of coolant. Some rare jobs coolant is a bad idea, and tooling +/- speed is everything. Well done!
