Repair BROKEN End on D8 Dozer Push Arm | Gouging & Welding
This video is a job we did to repair & replace a broken trunnion bearing end on a Push Arm for a Caterpillar D8T Bulldozer. The trunnion end has a crack all the way through it and we need to replace it. This shows the step by step process to remove the cracked trunnion end using air arc gouging and prep the side arm before fitting and mig welding on the new trunnion end.
In this video we are using:
- Lincoln Electric DC-400 Welder
- WIA 500i Weldmatic welder

Yup it's raining AGAIN! We're in a La Niña event and have had so much rain this year it seems like every video it's been raining LOL. And of course Mr Big Nutz got beyond spoilt this week with gifts from viewers thank you! We would love to suggest instead of of toys/treats please consider *donating* to QLD Staffy Rescue foundation here: www.qldstaffyandamstaffrescue.org.au/ 🐾🙌 Follow us online here 👇🤳 Instagram instagram.com/cutting_edge_engineering Facebook facebook.com/cuttingedgeengineeringaustralia/ Official CEE Merch shop: www.ceeshop.com.au
She's a big girl that's a Lincoln ideal Arc 400 right
"Mr Big Nutz". HA !!
your lucky you have rain we had snow and ice last night got below freezing ice on the porch and steps .. I am in NY near Buffalo NY 1 hour away
Kurtis, you have a dog that the world loves to spoil
Another fantastic video! Oh the carnage (poor chicken)! 😂 I have 4 four legged friends and yes it’s hard to keep toys in stock! BTW. Need more content, I’m suffering from from CEE withdraw, I have the shakes 😂😂. Until next time, CHEERS from the east coast of the USA. 🍻🍻🍻🍻🍻
How many of us have been sitting here for several minutes whacking the refresh button waiting for our weekly fix?
😂 we reckon Matty @matty's workshop must have the fastest internet in the world think he's commented first every video for the last few months
@@user404d LMAO it's machine porn for a reason 😂😂😂
@@CuttingEdgeEngineering We appreciate how you filled that crack.
Its an addicting drug
Here! 👋
Loving your work. I'm a professional diver. We gouge, cut and weld underwater regularly. We mainly use Broco rods for burning, and stick welding to put stuff back together. DC always, positive ground, good insulation and make sure you don't get your body between the work and the handpiece stinger cable, (ie, comes in from in front or the side). Get lots of tingles, teeth ache, chrome plating peels off all the equipment but we all survive. You're taking all the right safety precautions.
What sort of money mate? Ever don't any sat diving work?
Respect for your work and commitment Phil, but personally I will pass on doing that sort of work.
Hey mate thanks for taking time to watch and share some of what you have to deal with, always wanted to give that a go but I'm not a fan of the ocean or sharks 😂
I’ll tell ya brother you guys have balls of steel to do what you do, going through decompression and risking your lives every time you suit up . Much respect ✊
@@CuttingEdgeEngineering I don't know about you Kurtis, but I love flake :)🤣
Another donation to QLD Staffy Rescue on behalf of Homeless. Although I enjoyed watching Homeless destroy (eh, enjoy) my gift to him, it also feels good to help another homeless Staffy.
That welding/scaling/welding/scaling time-lapse was genius editing. Well done.
It was pretty slick!
Always amazed at the depth of knowledge and skill of this man. It’s unbelievable that he is a one man shop.
I read somewhere that the only two creatures that can work with Kurtis are his long suffering wife Karen, and his long spoiled Homeless Safety Officer.
@@amazeddude1780 Yeah I was going to say, one man, one wife, one dog shop.
thanks mate, I enjoy and prefer working by myself, only 1 dick head to worry about 😂👍
@@CuttingEdgeEngineering Ha ha. Love watching your channel. I haven't watched tellie for years now. Content that you provide is heaps better than stuff like The Bachelor Does His Block at First Sight. Keep on keeping on, much appreciated.
@@CuttingEdgeEngineering It would be impolite of me to disagree about your qualities. Laugh 'cause I am. You are a good operator Kurtis and have said so in comments on other videos. But you have a Larrakin quality about you as well and in true Australian manner, you don't take yourself too seriously. Good onya. The missus and the mutt also have Aussie characters of their own. 70 yr old retired mechanic/machinist also from Land Down Under.
It is an absolute pleasure to watch your videos U2. Firstly, Kurtis has achieved "God Level" machinist. Secondly, and of equal importance, Karen has an absolute uncanny ability to know when to 'change it up'. There are exactly ZERO places in these videos where I start to get bored watching the same action. I know Kurtis indicated in a previous video that he is 100% self taught. But I don't remember Karen saying if she was self taught or has formal training in videography. Either way, she is awesome at creating these videos.
I agree, there is never a skip ahead moment in the videos, that is down to Karen.
Yeah I’m loving her quiet demeanor during all the crazy milling. She must have seen enough “boring milling” and “boring boring” to just understand that we all watch BECAUSE it’s this way. I don’t watch a lot of milling things but I watch Kurtis and his work. Other channels talk waaay to much. If I ever post anything about my own DIY shit I’ll try to remember that its the project and not someone droning on and on a on to the camera.
@@johnkruton9708 Agree with you John, but there are times when an explanation comes in handy or if the host has a question about a particular topic and would like viewer feedback.
Man thanks for doing this safely. I have so many patients with lung cancer that were welders. Love seeing the respirator.
The precise loading of the welding machine wire and the filming was another Masterpiece!
i would have thought being from down under the threads would be backwards like the toilets. lol
One of the few channels I give a thumbs up too before I even start watching because it is always good. Keep up the great work! Dog flexing his chest with buttons open like a boss cracked me right up.
thank you mate we really appreciate support like that. Yeah Homey doesn't skip his workouts 💪😂
@@CuttingEdgeEngineering his jaw muscles certainly get a workout turning his toys into plastic swarf
Better order up another shipping container for Homie's toys. The perils of being famous!
I reckon the toy box is over flowing!
Don't let him go full movie star on you. He's getting kinda pushy with those boxes!
I do believe that people from around your area are blessed to have someone who can fix these machines. With most companies pushing technology to prevent owners from fixing them, this also made most people treasure old school machines as they can be diagnosed easily without any need for software.
You are referring to the John Deere Right of Repair issues and the dangerous path that they and other companies are headed down. I think that to have any success, customers are going to have to start with an old fashioned letter writing campaign. The reason for suggesting using actual letters is to make a point about technology as well as going for the great vision of letters arriving at J D HQ. Let them know and their shareholders know that Customer Loyalty is a two way street. Tell them that you are considering buying a different brand when it comes to replacing a tractor or other item and let them count up the potential lost business.
@@markfryer9880 I've heard of JD's sorry behaviour (here on the Toob) from farmers who've been shafted. Knowing the names of any companies heading down the same path would be good. I've been thinking JD's actions would be good for the likes of Yanmar and Kubota but .....
Homeless must love the mailman.
Love the extra steps in making the job right. Changing the feed rollers in the welder, the nozzle tip, the wire, moving the thing outdoors to gouge, grinding the excess off the new part instead of just hitting it in with a bit of force. All these things make the videos so good to watch. Fucking love it man.
Hey mate thanks for watching and glad you enjoy all those little things that make up the video. Cheers
Beautiful work !
Loving the content from Kurtis as always but Karen’s video editing is a real treat. Thx for brightening up my Friday.
Glad you enjoyed it!
I LOVE THE OUTTAKES AT THE END!!!!!!!!
Great job mate. But homeless is definitely the star of the show and with the interesting things you do Kurtis. Great job Really interesting
Any videos starting with Homeless gets an instant like 😁
Hey Mrs Cutting Edge…Good camera work on that gouging operation! You got right in there! Looked very intense.
Giving the viewers up close shots i'm definitely for that!
I hope Karen has a PAPR, too. She records from such a close distance :-) Another cool video. Always a great way to end the work week.
safety first!
But hers will be pink.....
@@SeanBZA Hot Pink!
Homie is like im not spoilt im just well loved. He is just the happiest dog in the world. Thanks for another great video.
Those are some very pretty welds, sir. As a side note, every time I see Homeless now, I think of a D8's ripper shank - Australians... Cheers!
Fab filming Karen 👍, great work Kurtis as ever 😉… always love to see Homeless 🐶 get new toys 🧸 best wishes from 🇬🇧
Thank you!!
What a joy to refresh KZhead and find a CEE video! Greeting from Brazil!!
Hey mate thanks watching!
Very interesting seeing what makes the things you work on fail, how you go about repairing them and how they are designed and put together. Learned a lot of things that I didn't know from your videos.
awesome mate great to know things are being learned!
Another fantastic video! The detail and in depth explanations of the processes along with the quality videography have kept me coming back again and again! Can’t say how much I appreciate the time and energy that I know goes into these! Thanks again!
Awesome, thank you we definitely appreciate the comment
Nice torch work on the hand bevel, also keeps surprising me how quick and clean the air-arc gouging is.
Great intro back story on why the damage could happen and explanation on repair. I was also thinking that the work only took a few hours but the intro took the best part of a week 😂😂. Thanks guys.
mate you'd be spot on with that thought 😂
Of course it's a beautiful sunny day as soon as he's finished outside.
I used to know some welders that worked for a railroad tank car shop. Their welding equipment was not in good shape and they had to work outside in the winter, or rainy days. I saw one of them after getting off his shift. He had long black curl hair and a beard. When I saw him, the hair looked like an afro and the beard looked like it had caught fire. He had been welding under a tank car, the welding cables had bare spots and they touched the tracks where water was sitting. I'm surprised he was alive!
My worksite foreman today asked me how far down was the coolant in the wood chipper my response was 1 inch. Immediately my foreman responded with "so about 1 banana" your channel is growing faster than you know it!
haha that's brilliant mate! Metric Vs Banana war is going strong lol
The only thing that should ever be measured in imperial is thousandths of a banana, and even then, I often convert it back into hundredths of a mm, proper money, in my head so I can make sense of it . . . . . .
@@CuttingEdgeEngineering One day have Karen video you using a banana tape measure. See how many people notice and comment.
Another great video to all the grasshoppers out there in youtube land from the master of repair, the master of video production and the master of toy destruction.
Thank you mate!
Homey's always so spoiled! He's hilarious!
They are spoiling that crazy dog with so many gifts
👍 can’t wait to watch! Have a great weekend you guys!
cheers mate hope it's enjoyed!
Kurtis, Karen, and Homeless.....checking in with you and making sure you have a great weekend, I was just over at Max Grant's place in Swan Valley, figured I better get over to the Gold Coast and check in on you......Best Wishes, Paul
hey mate! thanks for checking in, we've got another long weekend coming up hope you have a good one Paul
@@CuttingEdgeEngineering you know I will...best wishes......amazing how straight you cut that trunion off...Karen, your camera work is amazing and the editing too.....
These close shots of Kurtis' particular actions remind me of La Nouvelle Vague movies. Fantastic job Karen.
Love watching you work. But best part of video is Homeless and outtakes.
Gold as always. Thanks for another GREAT 29 minutes and 39 seconds of escape on a Friday night here in N.Z. Cheers Pete'.
Hey Pete thanks for taking time to watch and comment over the ditch
@@CuttingEdgeEngineering Cheers to you threesom. Hope the weather comes right.
Homeless is not spoiled. He’s just well taken care of.
and loved by many!
Karen, that slow motion of the needler striking the flux, one needle at a time, was marvelous. Made me smile. Thanks.
5:19" must have earplugs for gouging" Must have earplugs for all metal working.
I see your request for viewers to stop sending gifts for Homey is working well!!🤣
🤦♀️😂 very grateful for the generosity and how thoughtful viewers are but he is SO spoilt now LOL
You do know the dog is the star of the show don't ya? Great videos, keep up the good work.
What a shower of gifts to the movie star....Great work.
In construction we called those offset marks and they were very handy for laying out away from the actual device.
A crackin' masterclass in planning, preparation and execution! Always a pleasure to watch Kurtis!!
Glad you enjoyed it!
*_YAKETTY SAX_*_ as a ringtone?_ A man of culture, I see...
Karen, maybe you should do the intro, except that the out takes at the end are hilarious. Love your security, he is priceless at the table. He clearly knows what’s about to happen.
Homeless gets so focused on getting those goodies
every day he checks that desk for any new packages 😂
Great video again guys..the close up on the gouging was class 👏 👍
awesome mate glad that was enjoyed
This bring back so many memories, air arc, lovely warm feet in the middle of the winter, in the UK 🤣
Fifty years ago the shop I worked at used gouging rods (Oerlikon Citocut) for removing welds, not noisy but stunk the place out! Best Wishes from Somerset UK.
This is one of my favorite KZhead channels. Great work and attention to detail by Curtis, also the pup gets a few toys as well. Thanks for the content CEE!
hey mate glad you enjoy the channel 👍
always lloking forward for your fridays
Joy to have a new mig tip, and a new reel of wire.
That weld sizzle, dialed! Love the needle finish btw! IC approves ;)
Right on!
Nice job again by a great team. Explaining the possible causes of a failure like this was interesting and explaining why you use the method of cutting for this job also interesting. Being a retired electrician I understand well your precautions and safety measures you explained and use. It was nice to see Homie receive some goodies in the care packages,he's such a treat.. Keep up the great work,I really enjoy your videos. The camera tech did a fantastic job as usual. Stay safe and well.
A lot of goodies for HOMELESS......Great video
Amazing work
I've had to do that to many cat push arms years ago. D6 to D9G. Good job Kurtis.
awesome mate thanks for watching
I’ve been amazed watching your videos for the last couple months. Thank you for putting out these videos very in-depth I’ve learned a lot thank you
hey that's awesome mate glad you can learn something from it and we appreciate your support
as usual, when u are ready with all work outside the rain stop and sun will smile
Always a treat to watch you work.
I really enjoy the videos your wife, you, and the Safety Inspector produce each week. It is not only an enormous amount of work to film and edit it, but then to make a truly quality product is an amazing task - TOP NOTCH! My sincere hope is that your business and your KZhead channel is highly profitable. You and your small team deserve to keep every penny of it that the government won't take from you in taxes. I hope to see you add this incredibly great content to additional distributors' platforms. You'd do well anywhere you placed it. Thank you for the quality of your work in the shop and in these videos.
Always amazed at what you can do with the machinery,great work to both of you fabrication and camera,hello from the uk
hey mate glad you enjoy it!
Great work as usual
LOVELY WELDING BEADS !!!!!! Officer is WILD.....~~~~
Rain, LMAO try living in Wales, you start to grow webs between your toes. Fascinating insight into the life of a 'push arm'. Getting the odd electric shock as an apprentice definitely made us aware of best practices when working in the wet. The video was really good, thank you both.
yeah can only imagine! We're lucky enough to still get plenty of sunshine, has been a very wet year for us so far compared to normal
I put the electrodes under my arm to stop shocks when working in the rain , when i worked outside for 2 years as a apprentice in the sixties.
@@aytonbob I was an apprentice from 1971 in a medium sized engineering firm. We had a branch which manufactured industrial furnaces, that where we learnt our welding and cutting modules. I swear some of the welders were sadistic and would do things just to taunt us young apprentices. As we learnt more and more over the years, we paid them back. We were taught how not to get shocks at college, I found wellies and dry clothes / gloves worked, but speaking to guys since then they all had their own ways.
@@CuttingEdgeEngineeringBeen in Wales for 2 and a bit years , lovely spot in West Wales half way up the valley wall facing south. When it rains the stream on the right side becomes a small river and the waterfall on the left goes mental. The view is almost all green trees and fields, lovely. We moved to Wales as my wife has family around us, the move was because I'm terminally ill and wanted her to be mortgage free and among family when I do pop my clogs.
Great video, for those pop up canopies, I use 12 inch lag screws & an impact gun to hold them down. Faster and stronger than tent stakes.
Always solid information, great job !
Great job Curtis.
I helped build Subs for the Navy here in the States.Nice to see someone use a Arc rig with a skill set.This is a routine job in the shipyard.Nice work sir.Once you find that fuse line your golden.Im surprised you didn't Arc that bevel on while you were outside.Nice to see you welding that vertical uphill instead of down hill like alot of no welding clowns would of done.
I really admire the safety precautions you take around your shop. Your videos should be required for apprentices in the machine shop. And your explanations on the "why and how" the work needs to be done - well, they are simply the best I've seen.
Another great video you two .
Spot on!
Great job Kurtis 👏👏👏 Greetings from Manuel Torneiro channel Portugal 🇵🇹
Thanks a lot!
Karen, great filming and editing - I love how you show the first pass of welding in pretty thorough detail, then show "summary" shots of the rest of the passes over the same area, instead of just skipping ahead to "done!" I like the creative stitching together jump cuts, etc to "speed up time" without just resorting to a time lapse. really well done.
Top quality stuff!
Love the videos. Thank you for bringing us along with you.
This feels very much like an IC Weld job, very cool to see such similar skillsets in use on opposite ends of the planet.
Just found this video I always watch ic weld, grew up in machine shop, old welders had me welding at 8 years old. I love to watch men fix things the way they should be done. I get so tired of hearing ( it’s good enough for government work)
Well, I have been in mining for 12 years now and haven't heard it being called a "Push arm" before its usually called the draft arm here in WA, It may be different over east. Love the vids anyways.
Slamming off the broken part with a giant sledgehammer after carbon arc gouging in the rain...I think this is a new high water mark for manliness of a repair operation on this channel 😂
Another fine job - thanks for sharing
_»That's no hammer. THAT's a hammer.«_ Someone had to say it. 😁 Once again, thank you for a great start into my Friday. I really liked the damage analysis and the explanation of how that has probably happened. It's a bit weird to me that rock can actually break steel like this, but I suppose that depends on the rock. Anyway, good one, cheers! May everyone have a great weekend!
going to have to do a Crocodile Dundee impersonation one of these days! thanks for watching mate
@@CuttingEdgeEngineering Yeah. You do. You REALLY do.
@@CuttingEdgeEngineering Yes, my biggest one is called "Gentle Persuasion", even made a label that is on the handle to remind of that. Could not find the right handle, so a pick handle worked for it, with epoxy to help the wedges hold. It spends more time being the anvil than the hammer though.
@@SeanBZA Could make a great name for a race horse?
@@CuttingEdgeEngineering which leaves the role of Lind Kozlowski to fill?
Another nice repair made to look easy. Good work man, always nice to see!... lol, RIP poor little chicken.
haha cheers mate yeah little chicken did not last long!
Beautiful work and welds
I was very surprised that the arm is hollow. I figured it would be a monolithic piece of steel. I like how serious he is about safety.
Good Friday morning Kurtis 🥰😍 would you ever consider doing a video on how you cost out your work? I’m always trying to guess how much some of your videos would cost. Cheers as always 🥰😍❤️ hug the homie for me 😊
hey mate good question, we probably wouldn't do a video on that and make it public knowledge but might be able to including cost repair vs replacement etc on some future videos
Safety is paramount and I like that you let us know what some of the things are that you do to stay safe when you have to work in conditions that are, otherwise, definitely not good. Also love seeing work done where you've used gouging as a tool to remove ends from pieces that you're going to be repairing. I've never seen gouging used, or even heard of it, until I started watching your channel. My only question when it comes to gouging is; Why they haven't created something a bit more ergonomic to hold onto when doing the work? In regard to welding; You're the only person I've seen who heats up material before welding. Why don't more people do that? Is it more for types of materials used? I've also seen that on some jobs, like this one, you've welded in both directions. Does that matter at all for the strength of the weld?
hey mate thanks for watching and great questions here. The handpiece is designed to protect the operator has a lot of power and heat going through there so needs a lot of insulation. Pre-heating "heavy" and thick materials helps to reduce chance of thermal crack in the weld joint but not needed for light metal fab. The multi direction doesn't make a difference here for the weld strength. Cheers
@@CuttingEdgeEngineering Ty for the answers. :D
@Redman147 From my prospective as a power engineer, I can attest to Kurtis heating up the 'material' first is very wise indeed. For example when I fired up a steam boiler from a cold start, it took a long long time and was tedious, but was crucial to do it slow, timer in hand On/Off. The last thing you'd want is to go fast on start-up and initiate an unwanted crack. Without going into great detail about cyclic rates, it's VERY important from my side. I understand this fully. Cheers. ps: I also wish people here in Canada would STOP revving their car engines on the coldest days of winter on start-up. I hear it all too often, and I would bet those broken down stalled cars I see on my way to work are the people that don't realize what they have done, and blame it on the cars instead of themselves🤦♂. I thought I'd mention that too.
NICE WORK.
Good video. That pup is a smartie.
Love your videos! I'm curious why you couldn't use a band saw to cut the square tubing versus the arc gouging system.
hey mate good question, you could use a bandsaw but you don't have any "control" over the cut & location of the weld joint, you'd have to get it spot on or run the risk of extra cutting or extra welding to fill the joint. Where with gouging can be much more precise at only removing the material needed to separate the end and find the weld joint. 😎👍
Anyone can use a band saw :P Also blade deflection , squareness etc...
Thanks for the answer! Fascinating! - Joe in Seattle. 😁🤙
Love your posting schedule. 5 on a Friday, tired as shit, CEE video, happy as shit. Don't know absolutely anything about machining metal but I find your videos extremely interesting
awesome mate glad it works out for you haha
Excellent job guy's, keep'um coming..
Great video guys! It's awesome watching you work.
Curtis another great and informative video many thanks. One question that is probably so very obvious to you but would like "your slant" on it why use your gas mix with a flux cored wire as obviously the gas is not free etc? I am assuming it just shields the weld that much better etc so gas cost is offset by possible time lost grinding and cleaning?
hey mate, the wire is a dual shield and requires mixed gas combo in order for it to work correctly. Yes it does shield the wire but if you attempt to weld with this wire and no gas it would end up full of porosity.
@@CuttingEdgeEngineering Now I'm really puzzled, I looked up the Fabco tech sheet and it doesn't say flux cored, which with the slag it obviously is, and it says 75/25 argo co2 !!
@@rl3898 I did the same thing and the Hobart site doesn't really make it super clear does it? After a while I did determine/confirm that it is indeed a flux cored wire, and it's designed to work in conjunction with the shielding gas. My understanding is that you get better penetration, and properties with the combination of the two arc shielding methods. It's not something that I've had to use, but nothing I weld here at home is this heavy.
You don't need a swear jar , you need a 44 gallons drum😆😆😆 In thought that one of your jobs over the holiday break was to build a roof between two containers so that you don't have to work in the rain ?????? Don't knock us train drivers ( especially us retired ones )👍👍👍
haha yes planning on putting an "igloo" shelter up and was regretting not having that done yet!
Lol, mail time with Homey is hilarious! These videos make me want to get a machine shop and a dog.
You should!
As always, care and precision!
09:32 don't force it get a bigger hammer 😎
my favourite tool haha
