- Hey guys, follow along as I make some temporary/permanent repairs to this Hitachi excavator track frame. Im not too familiar with these machines but I am not a big fan of this design. Is it me or does it look shortsighted?

The only people who dont make mistakes are people who dont do anything, thanks for showing the real world. Great job as usual!
I only ever made one mistake.....
This one time I admitted to having made a mistake....... turns out I was wrong....😎🙂
On the money there Jerry Lee. Sometimes no matter how hard you try, you still end up making a mistake. That can come about due to fatigue, rushing for a deadline, the list is endless. It's how you recover from a mistake that makes the difference! Failing that, if it is too far gone, then owning up to the mistake is all that you can do.
What an amazing combination of attitude and skill! Given the variety and novelty of situations you face, you make very few mistakes. And you just recognize them, solve the problem and move on. I'm an amateur at welding and you're an inspiration to me.
Im a retired master goldsmith and 50 years ago l was told "youre going to make mistakes. The secret to being a great goldsmith is knowing how to fix your mistakes." If someone tells you they never make mistakes, run away. You are your own worst critic and thats a sign of a great metalsmith. Love your videos.
Spot on Tina! If someone tells you that they don't make mistakes, check to see if their nose is growing and get a couple of clean cotton tips to help clean their bullshit out your ears.
If that doesn't work, tell them to GTFO and don't let the door hit them on their arse on the way out.
If you are not making a few mistakes you are not learning anything.
I make at least 15 mistakes a day and I catch at least 10 …. I learn from them all
Watching your videos always reminds me of two things. 1) slowing down and being careful almost always leads to a better and faster job. 2) everything is a chipping hammer! Great work. Thank you for teaching us.
The Old Expression/s.
The faster I go the further I get behind.
I have two speeds, you won't like the other one.
Your torch work is like no one else man... the way that plate came off after you just cut the weld is amazing.
Great work as usual Isaac 👍🏻
Agreed. The first video of Isaacs's I watched was his torch work, and I was blown away. Then I watched him replacing a kingpin on an equipment trailer and that was it. He really is one of the best welders I've seen. I've learned a heck of a lot watching his videos. Truly amazing stuff.
I STILL can't cut very well with a torch, I guess I don't do it enough. But, this dude is very good at his craft and it's pretty easy for him, he knows exactly what he wants to do and he does amazing work. One job that will never go away is the field repair of equipment, robots and AI will never be able to do that...
It’s easy. Anybody can do it
@@MustObeyTheRules LOLOLOL...uh huh. A monkey could cut a piece of steel with a torch, but it takes a heck of a lot of experience to do it at the level Isaac does.
@@pamike4873 you know what, you’re right. a chimpanzee could definitely learn how to run a torch.
I've worked on several EC 400's that had the same issues. The only thing we did different was once the wear surfaces were gouged out, we took 5/8" grade 100 chain from outside rail to outside rail with ratchet binders to tension them, and then used a 30 ton ram stretched between the inside rails to straighten them. We put AR 500 plate back in place to help reduce future wear. So far no call backs. You did a nice job the way you did it also.👍
How about lengthening that slider which is in the wheel assembly? The original one is so short that it creates a pivot point, and the wheel can wobble around almost in any direction/ creates forces which pushes those plates up and down and side to side.
Make the slider as long as the groove in the frame, then the whole length of the frame box and plates will take the forces, and not the short area of the plate which was now worn out.
I was also thinking AR500 would be a good choice for this repair while watching the video.
That measurement snafu isn’t really a big mistake. Now if you had welded both 3/4” pieces in place and the idler wouldn’t go in and you had to gouge them off and wait for new pieces - THAT would have been a mistake!
You make me see how weak and feeble I am at cutting and welding! That was artwork .I am glad Scrappy mentioned your channel on one of his videos. I am going to be learning how real welders do it now! Thank you and becareful out there.
Very satisfying watching you knock that lower plate off with ease!
World class rig welder getting it done right there. Knock out major repairs in an afternoon and do a good job of it. Not everything always goes as planned but the important part is you learn from it and get it done right. I hope the people in your work area properly recognize the value of what's at their disposal. Top notch 👍
There was nothing easy about this job, in spite of the setbacks you managed to deliver in the clutch! Well done and thanks for another informative tutorial.
Brings back memories, had the same job on a 330 that worked in a granite quarry on the west coast of Scotland, two of us had a van, welder/genny on a trailer and some one inch hardox plate.
Same as you the inside track box was bent in, out of line.
It was a very remote location and the weather was crap….so as you did we started to gas axe away the worn guide plate then realised the upper and lower plates were different thicknesses and the hardox we had was thicker than both.
Long story shortened, our fix was to cut a slot thru the track box full length of the wear plate, set the idler on the chain to it’s original height…ish 😎 cut the hardox to size and push it thru into position using wedges and a jack, tacked in the four plates, pulled out the idler and finished off the welding.
I’m feeling a bit insecure about my skills. This man cuts with a torch and leaves a smoother finish than I do with a grinder😂. I salute you, Sir. Thanks for posting your work and sharing your skills with us backyard warriors.
Isaac is just showing you the benchmark to aim for!
If you watch his techniques carefully you will learn how he goes about things and with practice you can replicate his actions.
Did you notice just how he was going about cutting away the projection of the lower plate on the right-hand side? He would bite off a piece and then go back and cut closer to the lower parent metal on the second pass.
Watch it again as it was an interesting technique.
I was told once at the beginning of my career "if a salesman is not in trouble he is not doing anything to sell"! I learned over 32 years in sales that was !))% accurate. Nice repair and recovery for the mistake. Thanks for posting and take care!
Great video Isaac! Thank You for showing the washing tip on the oxy-acetylene. Very cool! If you remember you used that because it doesn’t heat the metal up as much as the arc gouging. That’s important to know. Watching you I have learned a lot about heating the metal and in this case it was smart to use the oxy-acetylene on the warped side. You will probably get more hours out of that repair since you chose that route because you didn’t jeopardize the tempered steel that’s already weakened. Just a theory.
I imagine the hiccups and video uploads get overwhelming, but do know, we all highly appreciate watching your craftsmanship. 🙏
Good job Issac! We miss seeing you and your son working together.
I've kept foiled foods hot on the engine just like that for years. Works well! God bless!
At least you caught the mistake before you welded the 3/4 plate in. Lots of guys have mistakes bigger than that on their good days. Thanks for another good video.
Been a welder all my life, after all these years I'm still learning from you & you validate my work. Thank you. Your torch work is simply amazing
Dare to say we all love your work. These days peasants aren’t allowed in workshops but you bring us right in and make us feel we belong...you are a treasure Thankyou for sharing your days with us...we feel your pride of workmanship whatever background we have...we become a tiny bit of your experience...many will know what I’m trying to say....
Well said Peter!
All the better , in a day , for life , some are just a pleasure to watch working his skills of retro repair on the fly...✌️👍🙏🤔💎
I love the fact that you love/live for a challenge, and take it on not knowing, great video
Always!
As a Farrier the forge works well for lunch too! Well done. That's how I prefer it. When I worked in sandblasting we used the Ingersoll Rand engines for the burrito 🌯. Love your skill level.
Nice, I always learn something watching your channel. I have the most respect for someone who shows their mistakes when they could be edited out. That's why I'm a subscriber
You don't get as good as you are without making mistakes along the way! No matter how long you've been doing it! It's how we all learn! I've seen a lot of welders in the kind of work I used to do! You are one of the best I've seen! Thanks for keeping it real!
For a guy who made a lot of mistakes, he has a great attitude! Such an awesome person, always learning!
Grabs lunch off the manefold Like a boss. Some days it goes in like it's slick, and others like it's sick. But you're still the boss. Don't beat yourself up,it's better than I could do.
Lunch break! Great warmer!
Used to warm MREs that way when I was in the Army. Nice work. I appreciate your skill.
you are the master !!!! this time i get to blink. in the time you took to weld the new pieces in all that was needed was to build up the top ones, to bring idlar down and narrower. buildup bearing cap and hit it all with grinder! this time you brought it back to factory. this system is way easier than a d8k. but you did show me a better way to replace those strips you truly are admired by me
Excellent torch work..impressive
Thank you for sharing your talent.
Loved the lunch break. I did that 35 years ago on a 4 day boat trip up the Hudson river in NY. We had lots of food in the coolers. My friends thought I was crazy but I got the last laugh. I was the only one that got a hot meal.
I actually made a SS metal tray that I hard mounted in the engine bay of my first welding rig. it worked great because I could leave my tacos and canned food in there while I was driving. worked pretty good.
@@ICWeld I appreciate your thought process, some guys just dive in without thinking, you seem calm and have a plan good job love watching you use the torch!
Thanks for showing us Isaac, looks fine to me. I get lots of days like that!👍🏼👍🏼😀
I enjoy watching your videos. Real world. A welder must be very confident in himself and his equipment’s capabilites before attempting something like this.
Sometimes Arc gouging is the way to go on repairs in tight areas. It is always great to see someone els that also takes pride it all of his repairs and making them look as close and some times even better then the original peace. Great Job man keep up the good work 👏 one day i hope to be doing something like you are doing with a rig and all. For now im stuck at a heavy equipment company making repairs and lots of fabrication. Have a blessed day 🙏
Yep arc gouging sucks but pretty hard to beat for accuracy and accessibility
Awesome work,, reminds me of the days when we used to tare down , haul, and reup equiptment
Years ago when I lost my License, I got placed into the welding department.(I Was driving the Truck), I found out that you have to learn how to fix mistakes of others and also your own.
Climbing uphill all dang day, with all the mishaps, you still kept at it and turned out top notch freakin work! It helps you enjoy some part of your job when you see the quality of your work Inspires others. Also the people you have trained or taught show promise that the average "Joes" don't seem to have. * We had a chart when driving the company truck to check off Oil level, coolant, belts hoses etc. You Might have a checklist -(Of your own design) Welding wire, different gasses, tips etc. to be checked before the am jaunt Monday, so that you you are properly armed with all your consumables. (or maybe an assistant lol?) Great job by the way. My favorite content list you are high on the list Man.
Your awesome! You always impress me with your skill and professionalism. Keep being Deadly
I have built up worn area with 7018 then hard face rods and ground smooth for fast repair on a dozer rail once.
Nice repair.
Хороший мастер , хорошая работа ! Привет из России
Hello Russia from Oklahoma u.s.a
Well you did it again fixed the pile of junk so the contractor can go on his way . Good eye finding the problem with the spread on the opening hopefully the wheel stays on, all and all you did another spectacular job🤠
This is probably caused by 3 tip turns on the idlers instead of the drives. Puts tremendous strain on the framework.
I didn't blink all the time you were cutting out the metal. You cut metal better than I butter my bread.
U.K. It's nice to see an honest channel - you can't win them all first time but you ended up with your usual good job. I'll say it for you 'thod it'. Take care and all the best from soggy England.
Seen a lot of torch cutting over the years. You are right up there in the top five. Slick man. Absolutely slick!! Nice to see this as my jd 70 d has the same problem. It isn’t hucking tracks yet. But it’s very sloppy. What you did was exactly what I saw doing in my head. Thanks.
That is some fine torch work.
Glad you showed the finished job 👍🏻. I would have lost a lot of sleep not knowing how it turned out !!! Great job as usual
LOVE IT DUDE!!! FCAW IS SUPER RAD AND WILD!!! I JUST STARTED MESSING AROUND WITH FCAW-S.
You are the first person on RUclips that I've seen use a washing tip on your torch. We called them rivet washing tips. They were the cats meow for removing badly rusted bolt heads on engine exhaust flanges without damaging the base metal. I often yell at the computer screen "get a rivet washing tip" to guys burning off bolt heads or nuts and damaging the area around a bolt by using a regular cutting tip.
Thanks for posting your videos. I like all the different project you tackle.
"Not bad for a rookie" 🤣 I'd hand you rod for minimum wage any day brother - it's a pleasure to watch you work
Im not a fabricator or welder professionally but I do like to run a bead from time to time. Not only have I learned techniques from you I've also been exposed to tools that I didn't know existed
Great job! I always refer to those 'Statue' days as 'continuing education'. You learn at an expense. Keep up the great videos. More carbon gouging please!
Hahaha...!
“it looks like a mess, because it is a mess”...
I have seen many of your other jobs, that have warranted “those words”..., but I know they always turn out awesome...
Great video,
Thank you sir.
P.S., I have never made those kinds of measuring mistakes..., more than a dozen or so times... hahaha...!
As the line in a song goes..., “some days are diamonds, and some days are gold”...

Right on
Coffees on!! ..Enjoying !! Cheers!!;-)!!!
Isaac, you are an artist with the torch. Amazing work and a great save from a small mistake. Thanks for taking us along. 😎👍
Hell of a good job mate, don't be so hard on yourself...👍
4 wear plates and a few countersunk screws: no work for IC-weld ;-)
The gentleman in the videos gives me the confidence to have a go myself but not on big stuff❤👀👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
Looking Good. Started out like a Monday but you made it work.
☆☆☆☆☆rating. Be safe/Healthy.
It happens. Get the bad day out of the way and move on. Thank you for your videos.
Hitachi Ex200 dash 5. Great machines. A lot of dash 5s still at work here in Ireland. 3 Ex800 dash 5s still working in our local quarry
I live in NZ and worked on plenty of Hitachi excavators with that exact problem. Some threaded rod, cut a couple of small holes in the track frame and use a enerpac with some heat to pull them in straight. Then weld a stiffener on both sides of the track frame horizontally from the front about 4 feet long. This will stop it spreading again.
Noted. I will mention that to the customer. Thanks bud.
Sounds like my normal day 😁
Murphy's law strikes again
Great video, always learn something! The struggle bus was stopped at that work site for sure!
Smooth operator!🤓👍
you will no doubt need the 3/4" pieces for the other side it's more than likely in the same condition stay safe have fun
Watching you cut steel with a torch,was like watching a surgeon cutting skin,clean,fine cuts,just amazing to watch you work!! And then to have the description of how,and why you make the repairs always great additions to the video's!!😎😎😎
I'm surprised you don't use propane. Hugh Callihan from Victor said propane is best.Cleaner,cheaper ,more readily available,safer and everybody has a gas grill.I asked him because Victor had no stake in the game. Probably expensive to convert but no more to start with. Submarines have 6"hull s of Hy 80 burned with propane ,beautiful job! You are a torch master! Please use your choice!
first 👍's up IC WELD thanks for sharing
your knowledge with all of us and your expert skill at welding has taught me tremendously from watching your videos
When the A-TEAM fired up their Oxy/Act torch, you must have been the real working double. I don't think many welders would want to take on a job like that.
Wow you make it look so easy!
Great repair job. There are fewer and fewer people like you that can show up estimate what it will take to repair the problem then perform the work and return the equipment to use. Again,you do great work! I’m impressed!
Awesome torch skills!!!
I don't think anyone would watch you work and think that it is easy, but watching you I can see that it is _possible._
Not bad for a rookie he says. Probably the most skilled torch man on RUclips.
Once got myself a verbal warning in a warehouse for placing my lunch on a steam heating pipe. I was sick of queuing at lunch time for the microwave and warmed my lunch on a pipe. The verbal warning because the smell of hot food away from the canteen caused too much distraction. Yeah soft people!
It’s one of those days when you get nervous driving home. Been there.
Lol I work at an OEM that eliminated 5/8" from all weldmnts and stock because there were so many mistakes grabbing the wrong sized plate
Always enjoy your work ethic and honesty!
Nice work.
My pop called those tips a rivet cutter. I guess for washing rivet heads. Super handy
There you go! I forgot what they were called! :)
Great job
Really good field repair. The error on the plates is what it is. I was impressed it didn't open up more after you cut the ride plates out, craptastic design.
Your thumb nail mad me think you used Johnathan Winters picture from "its a mad mad world" movie. A legend IMHO. I am a Subscriber
No harm ,, no foul .. the customer got a good shop repair in the field on a crap design .. Hero or zero the job got done ;-}
*I C Weld* Bravo great idea making that piece tapered. Thank-you sir for taking the time to show us your work. God Bless. ((PS, One of those days, Lolooo))
great job, even with all the problems ........................what kind of steel did u use for the new plates? AR400? 4140?
I asked for AR400 or T-1 but who knows what they bought.
Anyone can get into a mess... its the skilled men that get out.
Thnks for ur instgrm messge.
We are human=not perfect...and as long as you learn and gain more experience on a broad range of eqpmnt its all good. All you can do is try with evrythng u do
I was taught those issues are called “learning experiences”,,,, after you work through them you should never experience that one again AND everyone is susceptible to them… 😁… I’ll bet you and your son had a conversation about how not to have this occur… great video… y’all stay safe…
Comment #501 never seen this Chanel before but they called the correct guy to go this Job. Nice work sir.
Welcome aboard!
amazed at your get it done ability when others would just say the machine is worm out and needs major part replacement is honorable, please tell what type of welding rod and wire you are using, thanks for making vids of your ability, you are a professional.
IC, I'm laughing with you. If you have never been out, you have never messed up. You have to get on the Bull to ride him.
very nice work there, as usual, thanks for the lesson/
This is extremely common for various undercarrage designs ive spent years of my life doing tensioner pocket repairs on komatsu doosan deere etc.
Cool fix
On older Hitachi 360s the track frames were very good and had gieds on all bottom rollers.
Abraço do Brasil, trabalho perfeito 😃👍
Catching the mistake early is always good. I would have opted to shorten the side plates and use the 3/4” plates so I wouldn’t have to come back but after having bad luck like that sometimes it’s best to call it a day. Those idlers definitely can move around at times. Thanks for showing us your work it’s very helpful ( where do you get those washy tips from) I’ve never seen them before?
That “cutting nozzle “ seldomly seen.
I’ve known its used to remove rivers by cut off the head close to but not damaging the plate. Good to see it still having a use.
I love your work!!
Man, I wish my torch work was just as half as good as yours is. I have all kinds of collateral damage when trying to separate a piece off of something I need to save/not damage.
Take your time👍
@@kirkrichardson4443 I do. I don't mean to make it sound like everything gets destroyed, it's just the it usually requires a bit of clean up with a grinder. I'm just jealous that his cuts are damn near laser-like lol.
