Repair TRUNNION for Caterpillars BIGGEST Dozer! | Milling & Welding

We’re making full use of our milling machine table for this job! We have a pair of blade lift cylinder barrels off the D11 Dozer with worn out trunnion mounts that need repairing. We show the step by step process of the repair starting with using our milling machine to turn down the worn mounts. We then set up the parts in our welding positioner to weld a consistent layer of new material. Once the weld has cooled down we machine the mounts back to spec in the milling machine before finish grinding and fitting the new bearings.

[@paintedblue1791]

You missed the opportunity to weld hanging from the ceiling on wires like Tom Cruse in Mission Impossible... Cue Music.. Du..Du .DuDu.

[@Telephonebill51]

Wow. Kurtis, that replay on the welding looked as tho you were getting flogged pretty bad by the barrel ! Almost looks as tho you could automate the welding there by duct taping the welding head to the fork! Kudos and Happy weekend! You've got the world by the ass!

[@cv990a4]

Very creative use of the forklift to weld the trunnions. But... not enough number 8 wire involved in the repair (or is that only a Kiwi thing?)

[@randytravis3998]

I was waiting for the Mission Impossible music to start and Kurtis to be in a sling from the chain hoist welding up the parts LOL,, 101 uses of a toaster oven . Homeless does a great job in his camera work ,, the world looks different at his view ..Another Great Video thankyou for taking the time it takes to put them together ,,

[@Renville80]

Gotta love Kurt's "if it's worth doing, it's worth doing right the first time" mentality and his creativity in getting the job done safely.

[@swms26]

I liked your last statement. If. If the customer doesn't ...then the repair will last a lifetime. "If" is keeping your business growing.

[@Psychaotix2001]

I absolutely love watching the videos you guys come out with, mostly because they're absolutely spot on. No BS, no awful music (And no, the music in the earlier videos isn't awful) and full of interesting methods to attack the problem. The rotary table and forklift solution was pure genius. Then there's Karen, who seems to get even more skillful with her video skills, edits and camera placement. You both are an excellent team and I think it's safe to say that if a repair comes to your shop, it's going to be done right.

[@ohasis8331]

I was a bit concerned when I saw the rotating barrel kissing his shirt front till I realised that we wouldn't be watching this if it turned out to be an issue.

[@ferrumignis]

@@ohasis8331 It's also turning very slowly, he'd have plenty of time to breath in a bit if he could feel it starting to push against him.

[@ohasis8331]

[@tototere]

Always impressed with your understanding of the physics,chemistry and spatial orientation involved. I love the out-takes where where Kurtis gets his turds wisted. btw: good gyro camera on Homie's backpack.

[@IanTheWoodchuck]

Kurtis... Your attention to detail and professionalism with ensuring that all your work is OEM-spec is nothing short of amazing! I've seen so many machinists half-ass the repair, and when I learn something I want to learn the RIGHT way to do it. I'm always comfortable that the info you pass along is solid. Good on ya!

[@emdkent]

I really like this channel. I like the people. I like the dog. I like the metal. I like the machines. I like the backup beep of the forklift. I like the BF parts. I like the precision and attention to detail. I like the editing and the editor's laugh. And I really like the outtakes

[@CuttingEdgeEngineering]

Glad you like all that mate 👍

[@MrPancake0825]

What is not to love about them!!❤😊

[@ctdieselnut]

Same. Whats not to love? Satisfying to watch anyone who takes pride in their work, and that goes for both of them. Ill add one, i like the explanations. A lot of it is experience you cant pick up from a book and you can't predict until you've done it before.

[@petegraham1458]

[@jjbkozack]

This channel, and This old tony, are the only channels that I hit like on as soon as I open it up. Never been dissapointed on either.

[@papaburf7275]

Love the versatility of the methods to repair components! Homeless cam was awesome -what a good natured dog. That call out by Karen in the outtakes after the first cutting pass on the mill was priceless -"uuuhhh, look at this". Thanks again from the Lone Star State!

[@brucematthews6417]

I saw Homeless bearing down on the chicken and then the scene cut. I'm assuming much noise ensued? Always a treat to see these snapshots of what life is like in this sort of machine shop. I'm a home hobby machinist so my scale of sizes is MUCH smaller. Cheers from Canada!

[@CuttingEdgeEngineering]

yeah that chicken is still alive and squeaking he can't kill it! 🤣 thanks for watching mate glad you enjoy the vids

[@barrygrant2907]

Man! This is hard work watching you work. Your attention to detail is awesome. Homey always adds the comedic touch, and Karen brings the video to life.

[@wayupnort6271]

World class editing as usual Karen! Well done on the repair! There’s a difference between doing a repair and doing a repair correctly!👍👍👍

[@kennycayson1485]

Hey mate from florida usa This is so soothing to watch for me lol I could watch your videos all day

[@kurtkorenko8943]

I recently did a very similar job with the same set up. But I used a pallet on the forks and laid on it to weld. It was pretty comfy actually. This is why I love job shop work. Every day offers challenges and it makes one think. You both do an amazing job. Great video as always!

[@almostanengineer]

One of the things I love about this channel is that when you have similar jobs, you always show us a different way to achieve the same result, and explain your reasoning why your choosing each method 😊

[@LukeA_55]

The one thing that always amazes me about your work, aside from the quality and craftsmanship you put into every single job, is how quickly and efficiently you get things done. It seems like you never waste a single second. Like maybe it's because I'm completely new to the world of machining and welding but it feels like it takes me 2-3 times as long as it should for so many things. Like with figuring out how to machine a part or fitting up a part for welding or even simple things like inspecting my parts, I get caught up on so many things. "Paralysis from over analysis" as IC Weld calls it Watching the way you work has definitely helped me find little tricks to get things done a lot faster

[@WilliamWagner-hq9ut]

The tolerance of the parts is amazing on a piece of machinery like the bull dozer.

[@markmunro8753]

Thank you team. I can watch your professional work all day. Homeless is the best toy inspector.❤❤❤.

[@emerenriquez1195]

I love the acrobatic talent you showed while welding! What a versatile talent you got kurtis. Followed by meticulous eyes of karen's camera, a perfect tandem with a playful mascot! Congratulations for another interesting video. Thank you.

[@neilfairless4589]

Been a while since we had a bit of Homey cam. Gotta love that hooch.

[@erniemathews5085]

Seeing the orientation of the trunnions and the long, unhandy barrels I couldn't imagine how you would do the work. That was really smart. I continue to be impressed.

[@jamesarnold6059]

You both never cease to amaze--doing the work we see on camera is a feat in itself--but add to that all the filming, editing, & who knows what else to produce these--so impressive.

[@bgcal50cal]

I love the way you used boring head as a turning tool. Most people think of a boring head to do internals only. I have used a boring head many times to turn a part too long to swing in my lathe.. Since I am located in the north east USA I can’t wait for Friday morning see what you are up to today! Love the camera work Karen does and watching Homey being Homey always make my day. Thankyou ALL

[@robertfullarton3020]

Hi Kurtis, always a pleasure to watch your videos.....a real professional.

[@hot_wheelz]

Kurtis really taking one for the team there half laying on the forklift to weld the giant spinning meltdown arm of death! Oh and Homey has really settled into wearing the camera harness! I love how he stopped mid journey on his way to the paddock to make sure that Karen was still following him and hadn't got lost 😂

[@centexmachineshop]

Excellent work on those big ol cylinders. Before I had a horizontal boring mill I used to do a lot of small scale internal and external “boring” on a #4 Kearney and Trecker horizontal mill that mostly was reserved for cutting large keyways. No where in the literature is there a load limit of workpiece but on several occasions had 10” dia shafts on the table with the outboard end supported by overhead hoist while cutting 2” wide keys. One time put a partially disassembled CAT D8800 block on the table to do some external turning of the front Trunnion type engine mount with a large Flynn boring head. I have no clue what it weighed but the power feeds didn’t seem to notice.

[@rb95051]

Kudos as usually for your skills and creativity but, this time, a big shout to Karen for her editing. Better each time, avoiding repetitive shots and better angles each time. You two are a tremendous team

[@CuttingEdgeEngineering]

thank you for the great feedback!!

[@petermackay8981]

[@paulsullivan6392]

High quality repair as always as well as some unique approaches to accomplish the job. Using your positional spindle & chuck in a horizontal plane and then the ladder and forklift is pure genius. The way you figure out your material handling methods is amazing to me,.

[@armick57]

I love watching a master at his craft!

[@billmartin7637]

I've done some welding but it amazes me with amount of knowledge he knows about the gases, wire types and everything. It just comes down to experience of which I'm very limited but I'm learning. Thank you very much for the lesson. 😂

I've really enjoyed watching you do the kind of work I've done, but on a much smaller scale, cars, motorcycles generally. I worked in a shop making boat shafts for a few years, setting up their CNC machines and we did shafts about six inches diameter, forty feet long. I really enjoy your great set of machines, quite impressive all around. Homey reminds me of my dog, Raven, a few years older, quite a bit bigger and heavier. Homey has a really great personality! Thanks!

[@davidmcmichael8113]

Trying something different reference welding I thought you were going to stand the tube vertical placing the trunnion horizontal and use the line boring machine welding feature. Not thinking you were going to reach all the way out there and do it by hand. WOW what skill. That was totally amazing. I’m so impressed with your skill level and quality of work. Truly it’s inspirational.
