One of neatest things about your channel is learning complexity used in building scrapers & other industrial machines. Watching repairs is just as good to watch, keep up great work, thanks!!!
I've done weld and fab for over 40 years. I could have done that, but I would have been a nervous wreck. Amazing work as always, and one hell of a service truck also. Always good to see you when I get home from the ammo plant after midnight. Keep em coming Brother. Be safe! Thomas, Mississippi!!
It's easy to see why you retain your clients, knowledgeable, capable and professional service is not that easy to find. Always enjoy watching you work =)
Amazing work quality!!! I’ve said it before but I’ll say it again, your work motivates me to do better work in my own business. Pleasure to watch. Thanks
Greg, You guys impress me each and every time!! Your approach is spot on, and the way I would absolutely want my machine done!! Better than new!! Thanks, Vic!!
It is amazing the levels of repair you achieve to bring good equipment back to life. As I've told you before I worked at the Decatur, IL plant where parts of the tractor scrapers are built. Many of the scraper bowls come from a plant in South America, actually Brazil. CAT has had a strong presence in Brazil back into the 60's and 70's. I'm looking forward to the videos to come. The complexity of this rebuild is over the top!!!!!!! Go Big Daddy!!!
Good video. One thing I will say is that giving your guys compliments goes a long way in enforcing a good work ethic. It's great that you do that in the open on youtube.
So, an entire ear broke off at the root of that "plate"... That must have taken some serious stress! I do notice you fix a lot of cracks and such on earth movers. I guess like most engineering, there are tradeoffs... Makes me wonder about ore trucks used in mining. They have to be stressed as much as an earth mover.. Love watching your channel! Thanks for doing these videos...
Your videos just keep getting better and boy, do you get some marathon field jobs! Like the farmers out east used to say; "make hay while the sun shines" - money in the bank, baby!
Holey moley Greg! That is some heavy duty repair/rebuild work. Looking forward to the next in sequence videos. Glad you showed all the plasma work you did!
I like the videos you do in the field best, and your explanations of how the machines work and how the parts fit together. I find them educational and enjoyable.
A series, NICE! Rebuilding/retooling a machine this size outside on an empty lot, on a hot summer Cali. day, is impressive as hell! That first cold beer is going to be GOOD!
Amazing how you can cut those scrapers to bits and weld um up like brand new again.. Awesome work. I wonder if you've ever done work for the Mellons down in San Berdo at all?
As usual, impressive work. Can't wait for the next parts. I'm curios what that part would cost, and do you get the measurements from factory manuals or prints or from the broken piece. Always amazed at your work.
Hi been watching and just wondering what size plasma you have to cut some of the materials you do with the thickness. Knowing a 80 amp does about 3/4 inch 19mm using 3 phase 415v
I have noticed in many of your videos that you extensively use a Miller Multimatic 220 running what I assume to be a 0.035 or 0.045 Dual Shield wire. Do you ever run into the Duty Cycle or Thermal Limits of the welder? Also what kind of shield gas/flow rate do you use? Love the content!
I use my 220 a lot but only run .035 solid wire through it. For dual shield I run the arcreach 12. Never trip any duty cycles. I run 30-50 cfh with 75% argon 25% co2
@@OFW Do you think the Miller 215 and 220 using the oem MIG gun could run 0.045” if not 0.035” dual shield wire, power and feed wise? The Miller 215 is capable of 27v and 600 on the WFS - in theory the 220 uses the same MIG electrics as 215. Thank You for thanking the time to answer my questions, and I just wanted to say I love the field work on all the heavy equipment. I am learning a lot not just about welding but heavy equipment too.
@@OFW 0.045 wire on a Miller 215@@OFW 0.045” wire. Since your reply, I have set my Miller 215 up to run 0.045” dual shield wire with c25. The Miller is capable of up to 27vdc and 600ipm WFS. On 1/4” to 3/8”I have tried several settings but seem to find myself back at 25v at 350ipm, but I’m struggling with settings and travel speeds etc. and getting wormhole porosity on the surface. Or the bead is roped up and not really wetting in. I try to keep a 3/4” stickout. If I get too close I get porosity, if I get too far, it seems to slip from Spray transfer to Globular and I get big spatter BB’s. You said you always run Lincoln 71a85, but I can only find that in 15 pound spools, so I settled for Blue Demon 0.045”, (and I’m a little underwhelmed by its performance), and I don’t think the Lincoln 15 spool will fit inside the Miller 215. I was forced to go on disability, and I am trying to find something I can do within my abilities and tight budget. I know every machine is different and wire brand makes a difference too, but could you please recommend a basic starting point for settings. I have tried standard 0.035” Flux Core, but I think the welds are brittle, and I. Hoping the dual shield will help improve penetration and weld strength. I have learned a lot from your videos, and truly appreciate your content. Your knowledge of heavy earthmoving machinery is very impressive.
@@OFW Thank You - those settings worked well for me. I want to try to run the Lincoln 71a75 but I can only find a box of four 15 pound spools. Do you know if those 15 pound spools will fit inside a Miller Multimatic 215, and if it is available anywhere as single rolls? Being on disability, I just can’t afford that much wire just to find out the roll is too big for my machine. Thanks for answering my questions, as it means more to me than you know.
Hi Greg, thanks for your Videos. I hope for a 1o part Series!!!! of that extensive re-build. Welding inside the transmission Housing must have been a job in hell. Luckyly your new Crewmember seems to be a bit "undersize" so he fits in there nicely: No offense! Greetings from Germany Manni the CAT Man. P.S. Get Jacob new pants. He is no credit to himself or your Company runnig around like that. Even the colour of his undershorts is no longer a secret. With all the weekend Jobs he is doing with you in the Apple Valley he should easy buy himself a new pair of workpants.
When you get finished with this machine I’ll ask about how many hours you billed for it. Do you ever use a cutting torch anymore, Or just the plasma cutter ???

Awesome work Greg ,huge fan of your work ethic
Wow. You guys are really getting after it. Congrats, and well done.
Nasty!! Time for a bigger shop, and 4 more swamp coolers
Great video. Huge man hours in the refit there. But cheaper to refit than buy new. Looking forward for part 2 and 3.
You could make an emergency phone stand out of welding wire and welding rods. 😊
Big undertaking but the right person for the job.
You're a guy with an impressive skill set! Excellent job completed once again.

Stay cool drink lots of Gatorade it's a heat wave
Hopefully customer is responsible for full cleaning of housing interior prior to reassembly 🙏

I'm curios what that part would cost, and do you get the measurements from factory manuals or prints or from the broken piece.
Always amazed at your work.
I would guess about $5,000 for the part. I get the measurements from CAT. But they are hard to get.
It would be interesting to know how many man hours you have in your jobs
Looks like a job for JB weld
If there's one thing I've learned from JustRolledIn, it's that spray foam is the new duct tape.
@@Cancun771 combine the two and it’ll hold anything

Yeah for spray foam, how did we survive before spray foam.

What do you call this? Restoration, Overhaul, Deposit level rebuild, ???
A little bit of everything. Rebuild and restore.
I wonder where the line goes in cost before it's not worth repairing these scrapers.

Hi been watching and just wondering what size plasma you have to cut some of the materials you do with the thickness. Knowing a 80 amp does about 3/4 inch 19mm using 3 phase 415v

What do you use a cutting torch for anymore
ever hear of a shop vac? lot of dirt trebeck
Shop vac….. there was one sitting right there.
wow, cat has really gone cheap on bowl sides now, I can see where they save material and assembly labor but at a huge cost to the owner
I agree. They engineer it to work, but not last.
