Line boring and Bore welding Caterpillar D10 Dozer push arm | Sir Meccanica WS2

In this video we are line boring and bore welding to repair a Caterpillar D10 Dozer push arm. The bushings are oversized so we are welding them up and boring them out to bring them back to size for standard bushings. We are using our Sir Meccanica WS2 portable in-line boring and bore welding machine. First is setting up and tack welding on the bearing mounts for positioning the line boring machine. We need to line bore out the eye material before bore welding to build up new material and then boring out to spec. The job is completed by cleaning up the eye surfaces and cryo freeze shrink fitting the new bushings using liquid nitrogen.

Your wife does an amazing job of the videos, very smooth, always in focus, and none of the crappy music fillers that other youtubers do. Her editing is top class too, VERY NICELY DONE as always! Oh, the machining is brilliant too. Thanks for posting.

That bore welding setup is one of the slickest things I've ever seen.

Your dog just cracks me up - just wants to be loved. The outtake with the dog jumping on your lap was priceless.

Customers, customers in my 50 years in the service business I had one customer on a 5month contract told me from the start, he didn't care how long it took or the cost just do it right . Although I had only one, it made up for all the penny pinchers and cheap scape, something for nothing dweebs I worked for . Nice job . God bless you and yours .

The person behind the camera you do a great job 🍻

Thank you for explaining about some of the measuring. You said on an older video it was boring but it’s not to me. Taking good measurement is an essential part of the job and I’m interested to see how you do it and any tips you are prepared to share. Thanks for all the videos that convey your passion for doing top quality work.

It makes me smile so much to see how happy Tank is, he loves being around you guys! I also have a little suggestion. When bore welding, I have found that if I take a piece of aluminum and use it as a back plate, it will help build that first corner so you don't need to do touchups afterwards and there is no extra grinding/cutting as the plate just falls off when you're done.

Thank you for giving me a crash course on line boring. I am a farm manager for over 13 years. And in order for me and my wife to live in the same town I'm going for an interview in a week on a possible line boring job. You have taught me allot on only one video today. Thanks and God's speed

Live on a farm here in Texas. This video is fascinating. We run dozers and until now, we’d of done bush mechanics to solve that issue. Amazing to see the right way to fix it. Thank you for sharing it. Keep it up and may Jesus bless y’all.

That fast-forward of the welding arc glow was beautiful, good filming job :)

[zzzubmno]

im not a machinist, or will ever even work in a shop, but love to learn and see how things are done. i find this really interesting. i had no idea some of those tools even existed. i learn something new everyday, thanks for the vid. and i love the ends of your vids with the bloopers. great work, keep the vids coming.

[humancattoy]

Jumping up to get a little love from you shows just how affectionate your pit bull is. He's quite a character.

[cottonp]

IT IS ABSOLUTELY INCREDIBLE TO SEE THAT YOU DON'T CUT CORNERS AND DOOLDSCHOOL WORK, EVEN THOUGH YOU HAVE UP TO THE MOMENT TOOLING!
A REAL CRAFTSMAN CAN DO THE JOB RIGHT, USUALLY FASTER THAN TRYING TO USE SHORTCUTS!
IT IS GREAT TO SEE THAT THERE ARE STILL REAL CRAFTSMAN LEFT, AND IT IS A PLEASURE TO WATCH, LIKE A FINE DANCE, BALLET!

[brennanlukas]

always interesting to see what rolls through the door to get fixed vs what gets scrapped, I imagine this service is a small fraction of what it would cost to replace the piece if one could even be had. must be nice working on something that is still a circle for once lol.

[ferrumignis]

The line boring and welding machine is an amazing bit of kit, just trying to get my head around how the wire feed for the MIG works without the wire getting twisted up! A great job as usual, and another excellent video.

[stephenthompson]

I love how it starts out clunking on a couple of proud bits of metal then it starts clunking around. Then progresses into a sweet smooth cut.

[rickguerrero]

I really must compliment you on having the brains and the balls AND the machines to tackle big, big jobs. This stuff isn’t for the faint of heart…..people entrust you to fix their serious rigs! And you get it done!

[rord]

Love the sound of metal being cut, just like freshly ground drill bits! You two do a great job! Keep em rolling, out the door!!

[minasianjohn]

It is good to see someone using their brain to complete a product that is well done and save money doing it, more important you have a happy customer that will keep you. Thanks for showing us " how to". Great job and i love the dog, keep the chips out of his paws.
