Line Boring & Bore Welding Caterpillar 730 Dump Truck A-frame Eye | Part 1 | Sir Meccanica WS2
This video is Part 1 of line boring and bore welding a Caterpillar 730 Articulated Dump Truck A-frame that has a badly worn eye causing the bushing to be loose. We are using our Sir Meccanica WS2 portable in-line boring and bore welding machine. First we need to remove a seized bolt on the A-frame footing before removing 3 broken bolts that hold the retaining plate to the eye. We then use the Sir Meccanica centering device to set the bearing mounts for positioning the line boring machine. The eye position has been so badly worn and bolt holes damaged that we need to line bore out a huge amount of damaged material and bore out to the depth of the bolt holes. We position and tack weld a run off ring to the eye, hand weld to fill the bolt holes before line boring again to give a clean surface ready for the bore welding in Part 2!

Thanks for sharing mate
is this your company ? keep up the great videos . got too love the last min jobs .. can't wait for part 2 ..
@@randytravis3998 hey mate yeah my business. Thanks for watching
@@randytravis3998 no its. friends video from texas..
My Misses walked into the office, took one look at the screen, shook her head, muttered "machinists' porn", turned around and walked out. Right you are dear.
Did you have your hand on it at the time?😆
HAHAHAHAHA GOOD ONE !!!
Hope you charged them your finest “we NEED it Monday raté”. 👍
Good, fast and cheap. Pick 2. Hopefully your client agreed to good and fast, and it ain't gonna be cheap!
For real.
Definitely concur
Is that the ASSHOLE!!! or the You have GOT to be Fucking KIDDING ME!!! Tax?
Doubletime plus a "Market Adjustment"!
I realize this is a three year old vidi, but my comment doesn’t mind. Good on you Kurtis for having to give up your free time to fix a critical part. The customer, hopefully, remembers what you did and keeps bringing you more work. Good investment.cheers
Loving the technical phrases Kurtis...it’s fucked! Describes it perfectly 🤙😂
Hahaaa I'm all about using the accurate phrases 🤣👍
This might go slightly beyond that, more like shagged.
These technical "Terms" are beyond me 🤔😂🤣👍keep them coming 👍👍Geoff Lewis UK 🏴🏴🏴
Nothing like staying up till 3am, to hear kurtis say "it's fucked!" 😂
well worth the wait me thinks 🤣🤣🤣
@@CuttingEdgeEngineering its 3 am here in the USA and i am watching your videos ..
I love listening to some of the old fella's we had this old machinist contracting in our shop got free rent for some odd jobs he worked right across from me. Lol we had this sales rep working in the office nice bloke looked like a pretty boy but they would joke around I hadn't been working there long when the rep walks in walks past jack calls out morning jack. Jack looks up and says yeah piss off arseholes lol I was shocked but smirking the sales rep looks at me and smirks. Lol I really did expect that. Another thing he would say is if someone did something stupid I got caught out. That will learn em. Lol he was well past retirement lol
🤣 Roger that!
Can’t be tight if it’s liquid
The best meme
I was watching the tell-tale signs of oxygen cutting, then the hole.. internally I was like "the madman actually did it"
Curtis i am constantly in awe of your ability to survey the damaged parts and come up with a solution to repair the concern ; you are truly a professional in your field
If this truck need to be back at work in the pit by Monday, I hope you charged the customer for the privilege of making that happen ! !
I believe he will I also think that from now on the gona take care of their trucks because a repair like this is for sure not cheap
every time i see your line boring / auto welder i think how much time and frustration it would have saved me when i was working on heavy equipment
Best part is the videographer's giggle and laugh
my wife does the same thing when she's helping me with a project....meanwhile i'm cussing up a storm.
Best part is allways the pup
@@T-rock_chr0n1c the safety officer? Haha
@@zeropoint7665 mine too lol…. They’re all the same lol
Best part is the dog. Also she is funny too
Love how you show an example of the machine and where the part you are fixing goes. Really pulls it together. Great content as always.
In the hands of someone who knows how to use it the boring machine is really amazing.
Just incredible watching the process of repairing a major component rather then binning it
I’m a red seal carpenter, but did a lot of lathe/drill/mill work fresh out of high school and into college at a pressure vessel plant. I worked with a bunch of Polish dudes who hardly knew a lick of English but likely were involved in the soviet space program back in the day. Metal fabrication on another level. Your work is top notch, brother. Always enjoy hearing the tools screaming on the stock your turning up. I can literally smell the coolant every time you start up the pump! Keep up the content, shop inspector needs to stop by a little more often.
love seeing someone with your skillset and equipment just working through these jobs especially on a weekend youre on a whole different level but one of us just the same👍
Working the night shift here in the states, made the night better when I saw there was a new video.. Thanks for the content Kurtis and Crew!
Hey mate glad to help 🤣👍
I used to say, "if the operators and mechanics had to fix it themselves, they would take better care of things." Oh and I would have never guessed that tool holder was shop made even with the chain parts incorporated into it. You sir are impressive.
AAAARRGGGHHH we MUST have it back by Monday! ........Saturday after twelve and Sunday is double time mate, and a couple of hundred more because you panic arses couldn't even wash it down! Nice work Kurtis!
Used to have a saying from my days in the Marine Corps, ( We the willing have done so much with so little for so long , we now feel qualified to attempt the impossible with nothing) . Great content 👍 Slip seating most any machine creates a maintenance problem, no one is responsible they just drive until there’s nothing left but the steering wheel.
Nice saying there mate. And you're pretty well spot on dry hire machines cop it
Semper Fi, Devil Dog! Ooh-Ra!
"...no one is responsible they just drive until there’s nothing left but the steering wheel." kzhead.info/sun/qM6dps-SrGeHp4E/bejne.html
watching your channel has opened my eyes to how diverse the welding industry is...i never knew there was such a machine that could bore a hole AND weld the same hole! serious wizardry there! love the outtakes at the end of each video too! haha...shits fucked! keep up the good solid honest work mate!
Hey mate thanks for watching. Yeah some serious advancements in welding technology these days. Would love a submerged arc welder someday 🤣👍
@@CuttingEdgeEngineering, planning to put in a pool, Kurtis?
Done the way it should be....... cleaned down Better all round to work on. Cheers mate love your work
Hey Nick cheers mate 😎👍
If your missus can work a camera, she can work a jet wash ;-)
they say " you might have to work with shit but don't have to work in it "
Was totally waiting for a "hot down down a hallway" joke with that bearing "fit". Maybe consider a weld fume extractor to save the lungs.
Hahaaa yeah she was well flogged
Every time I watch that boring machine I wonder what smart guy came up with it.
The phrase "All of this is f*cked" should absolutely be on a tshirt. I would wear that proudly while wrenching.
Bloody typical. Flog the machine until it can't go any further. Then take it to the mechanic and tell him we need it Monday. And that boring machine makes nice swarf. 😊
Yeah seems to be a standard with some customers 🤦♂️
@@CuttingEdgeEngineering And I hope you charge them like a wounded bull! Great entertainment btw. You give an insight into heavy engineering that many of us have never seen.
Job security for the mechanics
Whenever this happens to me I try to not be angry about it . Thank god somebody thought of you when they needed the job done fast and correctly. Being too busy is a blessing boys ! Tho it can be trying at times much love from 🇨🇦
That’s been loose for a long time to be that flogged, that should have been picked up in the daily or weekly service and inspection of the machine. Some operators, and I use operator very loosely in this case, are too precious to climb under a machine or get their hands dirty.
Had one presented to me that had pulled through the eye. Seem to remember using the same technical appraisal term that you used. Great job Kurtis, looking forward to part 2.
Supervisor dropped a work order and a part to be welded on my table a few nights ago. It was covered in oil, brass shavings, and masking tape. I cleaned just enough to do the repair and dropped the nasty shit on his office desk while he was out. Yeah Terry, I did it! Don't bring me dirty shit! Love your work brother! I tune in after work around 2AM every Saturday. Give Homeless a good rub for us. Mississippi, USA.
CEEA turning eggs into circles since 2017. No hole's to sloppy for us! It doesn't matter how big your hole is, we can fill it! Well used holes are our specialty! Done tight, fit right!
I would charge them like a bull for all that work mate
This is a hell of a lot more interesting than online english class. Thanks for making my friday a bit better, as always
Gday, I’d say that was rooted, obviously the operator didn’t give a shit cause you would have felt it floggin up and down but more then likely told to just drive it, I don’t think you would be far off in the 9kg of weld guess, I wish I lived closer to see this in process done in person, one day I might get up there and have a look hopefully, can’t wait to see part 2 mate, throughly enjoyed watching, cheers Matty
Hey Matty for sure let us know if you are ever heading up this way! Cheers, Kurtis 😎👍
Your clients are very lucky to have someone like you who is willing to take on a job like this on a Saturday evening to have it ready on Monday. You're one in a million Kurtis. 😁👍
What's that, they want it back first thing Monday and they couldn't even be arsed to run a hose over it. Hope you charged a premium hourly rate!
Id dunk it back in the mud before returning it, “yeah, what? Apart from the eye i returned it in original condition”
first thing i noticed too!! could of even hit it with a wire brush. hit em hard in the wallet!! 11th hour rush jobs, gotta love it..
What do you expect. They were too STUPID to do the maintenance that would have prevented the damage and down time in the first place. If it were me the project manager would be short about 9 pounds of ass and the cost of the repair.
Love the channel. The impossible we do straight away - miracles take slightly longer. Greetings from Townsville, Col.
Hey Col cheers mate 😎👍🇦🇺
so glad to see the amount of views and likes you are getting on your channel...you three are really rocking down under.....cheers from USA
Hello Kurtis and video person not forgetting Homey, if I have spelt his name correctly. As you said Kurtis the amount of material you have to put back is considerable. It amazes me the pounding the inserts take when matching the metal. (Are they carbide or ceramic) allways enjoy watching your videos and Homey, give him a "Cwtch" from me. Best wishes, Geoff Lewis, Wales, UK, 🏴🏴🏴
Proving once again books and grease are for nerds! Working in the shopping today guy says I haven’t seen that Australian guy lately he still on Every Friday Cool
We work for nerds though.
😎👊💥 legend
I imagine you’re measuring it off of those flange plate holes to centre it as best of an educated guess? Like I used to say in the trade, grease is cheap, mechanics aren’t, as with your case, neither are machinists.That’s some PM program they have there.
Standard procedure in the transport industry, why pay 50c for a copper washer when you can pay $20 grand for an engine rebuild. lol
No kidding. I am not surprised the bolt pattern on the flange is not usable. Nice Repair
That boring machine is the bees knees. Totally addicted to your channel and the funny thing is I'll never once in my life do anything that i watch you do every day. Great stuff Kurtis!
Kurtis - Weekends are a state of mind when you work for yourself. Gotta do what ya gotta do! Thanks for the vids
Kurtis, was it faster to work with the stretched eyelet and its egg-shaped bolt circle? When I first saw the damage, I incorrectly assumed that you would turn and bore a new eyelet on the lathe. I felt confused throughout the video because it seemed like a lot of extra work to salvage the existing eyelet. But I'm sure you can shed some light regarding your decision. Thanks!
Fantastic repair. Thanks for taking us through the problem, issues resolving the problem and then the eventual resolution process. Absolutly fascinating
Cheers mate thanks for always a great comment!
This is becoming one of my fav channels. That cliffhanger ending tho! Can't wait! Last bit of the vid is always the cherry on top
Can't beat the hot spanner for those stubborn bolts Keep up the good work
2:44 man thats some hot water in that can....look at it heat up that bolt :)
🤣 yes that's my coffee brewing water
Definitely not your first rodeo, tricky shit with the bolt holes can't wait for part 2 Cheers 🇨🇦🇨🇦👍
Thanks for watching mate!
These businesses are lucky to have a bloke like you around to fix their short sightedness and cost cutting measures. Hope you charged them 10k
What a cliff hanger!!! I love how you show us the machinery that these parts come off of. Very helpful in understanding what's going on! Thanks!
Rule #1 with tight bolts, they can't be tight if its liquid
The joys of being a business owner having to work on a Sunday late at night. I hope you told the customer "it's fucked and it's going to cost you". Great video!
Kurt you sure straighten up people's neglect don't you great job
Thouroughly enjoyed this .... until the end. “Ready” then you cut!! I forgot it was a two parter 🤬🙄👍🍺
Good one mate! If brute force ain't working, that means you're not using enough... LoL
Looking at the boring bar’s depth of cut into the surrounding bolt threads, looks like your centering efforts were dead on! Love this channel!
That was very interesting.. I love seeing how different parts are line bored/welded... Thanks for taking us along !
It’s awesome they gave it a really good wash before dropping it off to you! 🙄🙄
They are soooo thoughtful. Just love it when I get a weekend drop covered in shit 🤣
Hi mate, I always enjoy your videos and they're getting better and better !! Keep going the good work, all 3 of you !
Hey Jay thanks heaps mate! Appreciate the ongoing support
@@CuttingEdgeEngineering Love the "Ready ? YEP " CUT !!!
0:07 When this first appeared, I saw your hoisting strap and thought, "Isn't that cute. Someone welded that and put a wrapped bandage on it." 😂
I really like your Channel. Compared to other channels the things I really love are: Having a real camera operator Your interaction with the camera operator The text overlays on inserts etc Your commentary The out takes And the dog Keep up the good work.
Some classy joint replacement surgery, mate! Charge accordingly.
I thought you would cut the end but off and weld on a machined eye piece, cause that whole eye looked elongated.
Was looking for this comment, had the same thought 2/3rds thru the vid. Probably cant get one in that spec, even if you could it's less labor to bill out. I know theres a point of diminishing returns with that logic but then theres also the urgency. Customer wanting equipment back up monday after dropping the part off fri night. Either way you go, this wasn't going to be inexpensive.
i agree, because it looks like they thrashed the piss out of that A-Frame and half-assed the maintenance on it
I am 10 minutes in and already want to say, “nice work on the bolts and installing the centering jig!”.
Nothing like watching a Master do his work!!
This is my first comment for this channel after watching a few videos ( of course I subscribed!) and I've got to say how impressed I am . The subject matter is fascinating and the production and editing is spot on. The slow motion close ups are compelling and details like the opening font are excellent , thankyou for taking so much time to make these videos!.PS the staffy is a real character
Homey is the actual star!
So what your saying is that a few bottles of green Loctite bearing retainer wouldn't work with that gap?
Nah she was well fucked 😂😂😂
Love that doggo! He's a happy pup.
On the bright side, if you asked the customer to "keep an eye on the bearing clearances..." it might mean less business. Fantastic job bringing the old back to better than new.
молодец приятель! как всегда профессионально всё сделал 👍🏻👍🏻👍🏻👍🏻
если бы он мог говорить по-русски, он бы, наверное, сказал спасибо.
привет, приятель, спасибо за просмотр, оцените комментарий!
@@CuttingEdgeEngineering Россия смотрит!👍
@@shlossu6825 No idea what yall say but typing those characters on a standard keyboard seems like a feat.
Gotta love the old, "I need it first thing Monday morning" line. Every single customer that says that seems to think its our problem that they don't look after their shit. Seems to be typical in heavy industry and with anything hydraulic.
The boring machine is always great to watch.
Just watched this video for a second time, I simply cannot believe that the bearing housing was allowed to get so worn, and another thing is the turn around time your client expected. Bloody good show Kurtis on how you went about getting that pigs ear sorted!
I hope you called Cat and got a price for the replacement A frame and then charged him 9/10 that $$price for all the labor and aggravation you're putting into this. They deserve it for such shitty maintenance practice.
I agree! I had a customer who constantly pulled this crap until he brought me a part that was no longer available. I called around to find out what the new one would have cost if one was available. Of course he lost it. "I can buy a new one for less than that!" Of course I invited him to do so, which then he admitted there aren't any available. "So you got a deal, you brought me a pile of crap and I return to you a fully functional part ready to be used. Next time bring it to me for routine service and will cost you but a fraction! Of course he never did!
List price plus 20% ... they're not going to get the Cat part by Monday... ;-)
What a job! Love it can’t wait to see the next vid. Them things must expensive if they wanna pay for all that to be done
www.constructionsales.com.au/items/caterpillar/730/ I’m fairly sure even if he charged them the “suffer for ruining my weekend” price, he’s not getting close to 6 figures for his repair job xD
Thanks for watching mate. A new A-frame part about $8k but that's if they are even available here usually a 6-8 week wait on stock.
@@CuttingEdgeEngineering far out mate that’s crazy!!!! Lucky they are in good hands brother 👊
@@dylanshandley1246 I meant the a frame not the whole machine.
@@CuttingEdgeEngineering Kurtis what is involved in making up complete swap over parts for something like that? Is there the option to go from just repair work to fabrication of components?
GREAT music! Just wish there had been more. Well, you left me wanting more - a good thing.
Your one of the best machinist I've ever seen and as a pipe welder welding xbox ray piping all my life you are a fantastic welder as well.....
I can do it right, I can do it cheap, I can do it fast....choose any two! Hope you got a premium price for a rush job! Holy smokes...might have been easier to just saw the thing off and weld on a whole new eye...daggum
I was beginning to wonder about that option myself. Getting the alignment right in the three or more dimensions could be tricky.
Whatever that job was, it was not cheap. Good thing some outfit have more money than critical thinking :)
Do you have more right hand welding gloves then left? I got 3 pairs of gloves but 3 extra rights
Hahahaa yeah mate I've got a dozen or so extra rights and drives my missus crazy. Now I just get packs of Left Hand gloves from my supplier 🤣👌
Love watching this channel. I know absolutely nothing about this stuff but I’m definitely learning thanks to this channel. I’m watching from Billings, Montana. Very informative
Man alive that thing was worn badly. It’s a shame to see people treating equipment like that. I guess it was cheaper to ask you to do a rush job on a Sunday and pay you well,, than it was to have the machine sitting idle. Looking forward to part II Cheers from Tokyo Stu
Hey Stu thanks for watching again mate yeah they wanted that machine downtime to be zero!
Fuck, they'd owe a few cartons as a tip for a rush job like that.
Ah plan B, "it can't be stuck if its a liquid"
Nothing like a late friday rush job to ruin a weekend !
That is definitely what you call an "Engineering Weekend", caused by a lack of a few grammes of grease. That was out of round big time, ouch. Brilliant work Kurtis, great vlog both. Thanks for sharing. Regards John.
Hope whoever was supposed to be doing the maintenance on the dump truck has been as reamed out for letting things get so bad
Some of those are design flaws. They don't use big enough parts for the use it gets. They use a pin with a grease hole in the center that breaks or the self aligning bushing is too hard and it breaks from impact.
@@tiredoldmechanic1791 After working in mining the last 10 years Servicemen aren't shown there is a grease port there. I had an Intermediary shaft bearing friction weld and explode from rapid cooling on a Volvo A40D as an operator.
Not a welder or machinist, just trying to learn: why wouldn't you be able to sleeve this after boring, instead of welding the bore back to size?
would work for a while but then fail as there is not enough meat on the outer diameter to hold it for long. economics come into play here. been a farmer for 50 years and make and fix my own gear. when you haven,t got gear like kurtis you can come up with lots of alternative fixes
Hey mate fair question. We would never sleeve a job, personally don't consider it an adequate quality repair. They are prone to fail, as mentioned here lack of structural integrity plays a part too.
Looking good as always Kurtis !!!!!!!! It looks like you will spending the weekend at the shop , I'm looking forward to the finale !!!!!! Be blessed Brother !!!!!
You have a good woman there mate. Love the giggles, great editing, and willing to put in long hours. A true gem.
best narration video yet, you sound a lot more comfortable. Cool Job, I wish I had learned this type of career as a teenager
This video brought back many memories. Over 30 years ago I worked at a Cat dealership in eastern North Carolina. Because I was a certified welder I got to do lots of lift arm, boom, and bucket line boring. I'd set up the alignment bar first, then bore out the imperfections, and then using 1/8" 7018 welding rod build up the inner surface for final reboring to spec. I really loved doing that work. Great video and thanks for sharing! And for those of you who don't know, a fly cutter isn't for taking out pesky insects! :)
I like to drill out seized in bolts . Did one today a 14 mill stainless screw that bound up in the stainless housing . As long as the pilot hole is pretty well dead centre you can open up the hole till its a bit below the thread size and it will just screw out . You didnt have much time though .
Wow that cliff hanger at the end, top work, and loved the bloopers at the end!
Здравствуйте, очень нравится Ваш канал, больше всего радует что Вы профессионал всего дело, и, да кстати, хотя-бы говорите от чего эта вещь, некоторые голову ломают от чего и для чего это! Класс😎😎😎
Like we used to say "that's not really a Friday afternoon job!" Problem is, that one wasn't a Saturday afternoon job either. 🤣🤣 You're a good man though to keep working on it. I came across a mechanic once that couldn't be fucked working an extra hour to get a vehicle on the road that was desperately needed despite all the late hours that were put in on his behalf by other people. Definitely not happy Jan! 🤬 Vastly different circumstances I know, but same sort of sentiment. You're committed enough to see it through and you've earned a lot of respect for it, just don't let them take advantage of you too much. Good job so far! 👍
I love how the eye protection and lens protection are synced :) they work so well together
Did this type of work for 25 years in the field. Repaired these bores on the machine with barely enough room to do the work, all the welding and machining.
Yet again Kurtis in his element welding has heart out
Such a cliffhanger! I cant wait for part 2! Great work as always.
Don’t know Why the hell I watch you work after a full day of work at a fab shop myself
never seen that type of boreing head design. your the master at your craft!
