Replacing BROKEN Eye & Repair CRACKED Cylinder for D10 Dozer | Machining, Welding, Milling

This job was bigger than we thought! This video is a job we did to replace the broken eye and repair the barrel end on a hydraulic cylinder ripper lift barrel for a Caterpillar D10 Bulldozer. The eye was completely broken in half and had started pulling out of the base of the barrel causing bad cracks. This shows the step by step process to replace the eye on the hydraulic cylinder barrel and repair the cracks in the barrel end. We start with cutting the broken eye off, chasing out the cracks in the barrel end and stick welding to repair the end. We also machine up a new eye before fitting and welding the eye onto the barrel. We use our milling machine to finish bore the eye to spec before drilling & tapping a hole for the grease port. What do you think of the finished part?

In this video we are using:
- Hafco TM-1740G LAthe
- Hafco BM-63VE Milling machine
- WIA 500i Weldmatic welder

Blows my mind how some people have the knowledge, the expertise and the skill to do things like this, especially how good you weld, amazing.

[GuitarDad]

Wow. This video had it all. Assessing actual extent of damage. Stick welding. Mig welding. Non-destructive testing. Torch cutting. Lathe and mill work. This was a master’s class. Well done. 🤯

[feynthefallen]

"I would not have seen it" - Love that dry and straight-faced delivery, pure comedy. Made my day.

[henvan]

The photography and editing of these clips is just fantastic.

It's pretty cool to see the channel growing. Who would have thought that over 387, 000 people would enjoy watching some Aussie bloke make metal chips. It's a real testament to Kurtis' skill, Karen's cinematography, and of course Safety Officer Homie's oversight.

Love that there is no excessive music. Time lapse sections don't seem to alter the natural sound of the machines working which is cool. The editing is great and makes the craftsman look perfect which we see through the outtakes, he is not, but it very evident he is extremely skilled and has a lot of practical experience. This is an all around fantastic channel.

What a breath of fresh air, no added bullsh. Just right to point and explanation along the way. It's obvious why this channel grew. Never change. Keep it just as simple

Before watching the video, I did not believe that such a welding would be very solid, but after watching it, I really was convinced. This is the first time I have seen such a long and careful work and such a solid welding process. I really congratulate you. Greetings from Istanbul to beautiful Down Under.

Gotta admire Kurt’s depth of knowledge and his common sense. Whether machine or procedure, if it ain’t broke, don’t fix it!

[rogerwhittle]

At first glance, it was; "Oh no, not another dozer eye wrenched apart." Then you found the cracks in the end bowl and it got really interesting! Your facility with welding anything to anything else with an armoury of techniques is awesome. Most of all, I can't help but admire your "I do it this way because it always works for me."

That's not 'old fashioned' or cantankerous, it is good commercial sense. If there is no good, commercial or practical reason for doing something differently, apply engineer's rule one; "If it ain't broke, don't fix it." I can't claim to be the engineer you are, but it's always worked for me. Great vlog Kurtis and Karen's videography just gets better and better. (Her time shortening sequences, coupled to the slightly undercranked sound effects are particularly effective. Thanks all round.)

I don't even know what is the best on this channel: welding work, or precision lifting of parts of one sling. perfect balance.

[Saybeth]

This has to be one of the best repair videos on YouTube. Everything done perfectly! Great job!

[Rsenior]

Whoever is doing your editing, the blending of the audio during the sped up section is superb. The start and stop audio of the tools lines up perfectly. Well done!

[gatorguy]

Another excellent video! Being a retired engineer living in north Florida, I really enjoy your machine content and Curtis' skill in performing the repairs. The camera work is also impressive! Here in the U.S., we are just beginning to celebrate the July 4th Holiday; a few years ago I was in Australia during your Australia Day celebration. What a party!

[ianpendlebury]

At 5.10 you had me dodging in incoming shower of sparks! Your close ups of the stick welding arc were very was the welder himself - of course. Thanks for continuing to make these appreciated.

[jimseviltwin]

I don’t know shit about machining, but I can recognize craftsmanship - this guy is a master craftsman.

[ramanshah]

The time lapse of all that stick welding drove home the mind-blowing amount of patience that this work requires.

[chatbox]

The idea with the clock in the background is genius! You make everything look so simple and quick, so knowing the time it takes to do some tasks, really makes an emphasis on how time consuming and hard work it is. Thanks for another amazing video!

[James-imvd]

I could watch this stuff all day long, I love the way Curtis is so precise and all around A+ content. You can definitely tell he's been doing his job for a while, his workmanship shines in his finish products.
