Repairing Final Drive Spindle for BIG D11 Bulldozer! | Machining & Drilling

Ever wondered what goes into keeping a huge Caterpillar D11 Bulldozer moving mountains? In this video, we're tackling a worn duo cone assembly off a Cat D11 final drive spindle. We’ll show you the step-by-step process of replacing the old ring with a brand new, upgraded one. We'll be heating things up (safely, of course) to remove the old protective ring, then it's over to our big lathe for some precision machining. We’ll make some metal chips and sparks fly as we create the perfect seat for the new and improved duo cone retaining ring. But that's not all! We'll also be putting our big radial arm drill to work, meticulously drilling and tapping the new bolt holes. So, buckle up and join us as we give this D11 final drive spindle the overhaul it deserves!

In this video we are using:
- Shenyang CW6280B Lathe
- Hafco ZX3050X16 Radial Arm Drill

This repair put our recently repaired big lathe tailstock to the test, and it passed with flying colors! ☑ Plus, the shiny new digital readout scale and light made the job even more enjoyable. Upgrades all around! Let us know what you think in the comments! 😄👍

Are you guy's aware how much more interesting this channel is than ANYTHING produced by TV is?
Blessings and prayers from Sweden 🇸🇪

This is such high level work. It’s incredible that we low level novices are able to see such a master at work. YouTube is cool, but it’s still unique that a master owner…just happens to have a wife/business partner/office media manager/wildlife wrangler…posts their videos, so we can see how this all works.

I am a mechanical engineer in China. I will brew myself a cup of tea before 3pm every Friday, and then wait for you to upload the latest video by 3pm. This is the most anticipated and relaxing time of the week for me.

Kurtis, you remind me of my father. He’s guy that has worked his whole life, using his hands and his brain. His hands are hard but his heart is pure gold. Seeing you with Homie, Jeffrey, and George was very touching and just shows your gentle nature. God bless you brother.
Karen, thank you, sincerely, thank you for capturing those moments and letting us see the gentleman that you love.
Much love and respect to both of you!

[sawboneiomc]

Thanks mate for adding some cost perspective on these gives us a greater understanding of the work you do.

[barillius]

Karen! My dear.... THANK YOU for the few minutes of peace in the beginning with Homie, Jeoffrey and George. Just exactly what I needed without me really knowing or realizing it. You are amazing. Thank you!!!

[hoofhearted]

Because of the GoldRush show I know most of these big machines in mining.
Because of Curtis and Karen I know the value of competent machinists who can put and keep these in service. Well done cheers from Texas!!!

Those Butcherbirds really do have a beautiful song, the sound you expect to hear in tropical forests. Thank you Karen, Kurtis and Homie, have a great weekend guys.

In my younger days I worked on a horizontal borer in an aicraft repair facility. The comment that you made about the component belonging to the customer and any mistakes and consquent financial compensation would be born by you reminded me of the occasion when I'd carried out a modification on a customer's main undercarriage leg of a large aircraft only to find that the slot I'd milled was in the wrong place - aargh!!! Mainly sleepless nights followed but the situation was saved after the stress engineers and draughtsmen re-wrote the modification plan - phew!

[adamadkins]

The bird calls at 1:25 . . . and safety manager's obedience. . . remarkable. I love everything you present, these are just special. God bless you all.

[kcolombo]

Unbelievable! After 71 years on this planet, Im learning new things all the time...especially from Kurtis!

[rjung_ch]

Seven minutes online, what an honor to catch it early. Kurtis and Homeless and the birds singing in the background.

[warrendon]

This production, as usual, is first class. Starting with George, Jeffrey and Homey was brilliant. Kurtis displaying his fantastic skills and attention to detail and Karen's videography and editing makes it thoroughly entertaining, unmissable! Best channel on Youtube!

[stFlyingeagle]

It just blows me away to watch one man with this much knowledge move and repair parts that weigh so much. Well done.

[Rochesterhome]

As a kid, I worked with large, heavy equipment and steel structures. And while your videos have encouraged me now, as an older man, to purchase a 10L 1949 South Bend lathe to make chips, when I watch the size of the pieces you work on and look at my tiny 6" chuck, I really appreciate the thought and responsibility it takes to make or repair such large, expensive items. You are a great machinist, and although my parts are tiny in comparison, I learn from your experience. 

I look forward to your videos every Friday morning.

When it's snowing and blowing up here in upstate NY, USA, and I can't fish or golf, your videos inspire me to go make something.

[andylee]

May I just say, Mrs CE is a really talented cinematographer. The detail shots and slomos are great. What a team!

[michasternik]

Due to the time shift I can watch it in morning in Poland - what a perfect way to start a day :)

Something that never ceases to amaze me is the flexion that happens on larger pieces of machinery, regardless of its composition. Duo cone ring, aircraft wing, they're all flexible - to a point! Hope the weather starts to cool down there. Thanks for another great video!
