Repair TWO Damaged CAT 777 Dump Truck suspension parts | Line boring & Welding

This video is a job we had to repair two damaged Caterpillar 777 Dump Truck Suspension parts. These are the rear strut suspension cylinder barrels on the dump truck and the truck has been scrapped for parts. On these parts the internal bores are worn out and the outside of the eyes have been damaged after being gouged or oxy cut off the truck. To get the job done we are using our Sir Meccanica WS2 portable line boring & bore welding machine. First we need to repair the outside of the barrel eyes by grinding out the damaged material, welding up and using our 9” inch angle grinder to grind back to shape. The internal bores also need repairing as they are worn out so we get on to 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 eye is then ready for facing, cutting the chamfers and snap ring grooves. The repair is completed by drilling in the holes for the grease port and cleaning up the surfaces.

In this video we are using:
- Makita 2400W 9” inch Angle Grinder
- WIA Weldmatic 500i Welder
- Sir Meccanica WS2 Portable line boring machine

Hey viewers thanks for watching todays video from our workshop! Sadly Karen lost all the timelapse footage for this job so if it feels like there's some parts skipped that's why 😞 she was gutted and hopes you still enjoy what she edited 😎👍

One thing that I've learnt from this channel is that welding isn't just for joining metal together.

Can we just take a moment to appreciate the dexterity and careful touch on display with the forklift at 9:10?!?! Mad props.

[cali_nerd]

Caught this weeks right away. Last week I was too tired and passed out lol. Also some footage is better than no footage so thanks Karen for posting at least some of it.

Happy Staffy at the end he had such a big smile on his face proud of him self for killing that ball good

Moral of the story, cutting corners costs more in the long run. And Homeless need a new toy.

I can't see how you can carry on without extra staff. This channel could only drive more work to the company. As soon as a potential customer watches this channel and realises the expertise being put into these jobs along with complete transparency, they must be just praying something goes wrong so they can send in a job & watch CEE do their thing. I for one, love the idea of knowing exactly what is going on behind the scenes for a job my hard-earned cash is going into. This channel provides so much more than just interest, education and ideas for young adults thinking about engineering. This is appealing on so many levels. Love it.

As a nurse, interested in metal works, who worked in ER for quite a while, I DEMAND you to use your angle grinder only with the guard cover! Each and every one person who came into ER with (always massive!) injuries had 3 things in commen: 1. That never happened to them before. 2. They all thought that an accident like that could never happen to them. 3. They had no guard over the grinding disk! Keep up the good work, I love your channel!

Whoever came up with the snap gauge going *through* the boring bar is a genius. It sure beats trying to freehand measure the bore with an internal micrometer.

The thumbnail image looked like those eyes were chewed up and spit out. The video showed the full extent of the damage. And you brought both back to rights. Excellent.

[universite]

Thank you for finally using the excellent face protection for such hazardous work!

Those would make great lift props for The World's Strongest Man contest.

The quality of the work carried out each time just shines through brightly Kurtis; doesn’t matter, we all make mistakes Karen.😁 don’t sweat it!👍

[terrycannon]

Tools have come a long way from when I did this kind of work. I used to do the build up by hand. Great job look forward to the next one. Give Homeless a big hug for me.

[josephalexander]

I’m neither a machinist nor a welder, but I recognize skill when I see it. Filling those chips on the exterior was a pleasure to watch. Cheers!

[zarn]

Its always amazing what someone with skill and the right tools is able to do. Making repairs on equipment that costs thousands and making it look almost new is amazing.

[assassinlexx]

I am so impressed with how you tackle every job.
Just like Homeless tackles that job of destroying the green ball.
That squeaking? If that is a old turbine air vent. It is time drive a rod through it and end its miserable life. If you are reading this Karan. Have a couple of beers and forget about the slow-motion.
The both of you do a great job.
Aussie engineering at its finest 👍🦘💯🇭🇲

Nothing else is like the feeling of working with steel. You're a lucky fellar to be a machinist, having a good pup and a good gal filming ya while you pla..er, "work" in the shop :)

[nategreycanopywelding]

Top tier work. Kurtis made the repair look like a work of art. Karen still made the video top notch without the time lapse. Homeless however, needs to work on those hiding skills. Can’t be a good safety if you can’t hide🤣. The CEE team setting the standard!
