Repair BIG Final Drive Hub for CAT D10 Dozer | Machining & Drilling
In this video we need to repair a big final drive hub for a Caterpillar D10T Bulldozer. The duo cone seal area of the hub is worn out and needs to be modified and upgraded to suit a new duo cone seal ring (labyrinth seal). There are also two bolt holes in the flange that are damaged and need repair. So there is plenty of machining and drilling & tapping to get this job done. First we set it up in our LZMT lathe using a 950mm face plate and 6MT heavy duty live centre before machining to spec. After the machining is complete we use our radial arm drill for drilling the bolt holes to suit the new duo cone ring. We then finish off the job by repairing the two bolt holes in the hub. First we bore out the holes with an annular cutter, then machine up sleeves and interference fit using a pull bolt system. We hope you enjoy this video from our machining workshop!
In this video we are using:
- LZMT CW6280D Lathe
- Hafco ZX3050X16 Radial Arm Drill
- Hafco TM-1740G Lathe

@@gaz0463 thanks mate!!
If you bust a tap in an expansive part like that, little diamond core drills work to cut them out but they are slow and i mean painful slow and you will burn up a few to get through what's left of a tap but they have saved my ass a few times when all else has failed
This couple has done more for Australia's reputation than any politician. Cheers!
I was super confused about the drill bit size, but then he explained it in bananas ... all clear then.
That's got me thinking about what other fruit or even possibly vegetables you could use to describe machine tools/parts etc. The possibilities are almost endless. What could you do with a Mango, Turnip, Comquart or Aubergine - clean answers only please!!!!

Thanks for watching mate
Right?
Just retired from a 38 year machining career. Loved every day of it. I’d sort of forgotten some of the daily nuances of the shop. Loosely holding the bushing as you part it off. Feeling the torque of the spindle in the radial arm drill as you start the tap by hand. The sounds of 3 phase equipment starting and stopping. The feel and smell of chips and oil on your hands. Scraping burrs out with a rout-a-burr(careful, they’re also handy for slicing a hand open). I miss it already. Thanks, I enjoyed watching.
I'm not sure there is anyone out there more worthy of the title "master of your craft" than this guy.
I haven't gone to bed yet, this is the earliest I've caught a new episode. Love your explanations of what goes where and seeing the machines they go on
Thanks for watching so early!

Congratulations, you are very good and I like watching your videos and how you work, I like seeing how you restore certain equipment. I imagine that new ones would cost a lot. Ps, I was also in your country, in Sydey to visit my cousin who plays at the Opera House. I spent a wonderful month, the people are very friendly, beautiful city. Good day

My favorite bit was the imperial bananas. The ability to multiply and divide by 25.4 is an essential skill for a successful machinist. Followed closely by disassembling the lathe ways to be able to turn that massive drive hub.
You are an amazing man, Curtis. I sit in awe of your knowledge and your thoughtful explanations. Oh, and your outtakes show that even with all your capabilities, you're a regular guy anyone would enjoy having a beer with. Thank you for all your efforts, and kudos to the camera lady too, the giggles are priceless. I drink my coffee every morning in my Cutting-Edge Engineering coffee mug, it's my way of saying thank you every morning.
Just a great comment
His name is Kurtis.
My dad was an engineer, mainly with sheet metal. Your skill and knowledge for the job is rarely found in this ‘modern’ world, as is your dedication to do any job properly. Love watching this channel 👍🏻
The outtakes are always funny to watch, keeps me excited throughout the whole video !
And the spolier in there!!
I really like that you never do any heavy lifing. Youlet the machines to the work even though it might be the less convinient option here and there. Really smart to not wear yourself out at work!

@@rogerofrhodri That's the kinda shit I was always made to do by people that have the luxury of using all sorts of health-conserving equipment.
I've forgotten how many times I raised my eyebrows, at how coolly and calmly you described what you were going to do to repair this monstrous piece of an even more monstrous machine. Mesmerising doesn't even com close!
During my working period in the Machine Shop of Canadian Kenworth Truck Industry, I made Several Tap handles from the Scrap metals, Medium Size & Small Size, the general Forman was impressed of them & he asked me to handle them to the Companies Tool Crip, because it was a Company properties, so every one can use them & return back to the tool Crip. It's fair I guess. I am so impressed of the way you inserted the sleeve inside the hole hub.
"We are using a 5.15mm drill or a 13/64 in bananas." Every time he refers to imperial as bananas it cracks me up!

Wonderful slow motion. Excellent work by the camera person. Love the outtakes.
I like that Curtis explains the process, the parts needed, and gives the cost of parts. I am a retired general residential contractor and now a registered nurse. I don't drive tractors nor do any machining and I find this type of work intriguing, rewarding, and just awesome. Let's be honest. Who doesn't like fixing things?
Now you fix people! Nice.

Loved the slo mo Karen did when you cleared the swarf with your finger. Funny stuff. Excellent video start to finish. Wished I'd found you guys sooner. Thanks
It was very interesting to see such professional work. I especially enjoyed the Duo-Cone Seal areas. I worked at Cat / Mossville in the 1970s in a program to develop a cheaper seal (but effective)for final drives and track rollers. It was just impossible to develop a hardened steel alternative to Stellite. It was neat how you could see the wear pattern on those face seals to determine how much time remained before replacement. Stellite as I remember was not only extremely hard but brittle as well...I remember how dropping one on a concrete floor almost guaranteed shattering. We had some success with the track roller size in the D4-D6 range, but with anything larger or for final drives, we just couldn't begin to attain the life or sealing capability of a true DUO-CONE seal. Thanks for the memories.
zionfrost,I worked on the old 46A and the finals on it when the worked in the dump always got wire or something caught in the finals and it was quite a chore to repair and the mating surface on the matching surface and the bearings were totally gone.
That comparison between this part and the same bobcat part really helps show the scale of the d10.
Yeah pretty impressive and to think that's just 1 part of the machine 💪🤯
I love the mix of precission engineering and hitting it with a big hammer☺
The camera work was downright cinematographic on this one. What a treat!
Watching you work reminds me of my father doing the same work 40 years ago here in the US ( new Jersey) when i was a boy and young man. Pure professionalism and precision. Love the pup too, he is a love.
I have an old American Lathe in my garage in the UK. 1930`s LeBlond. Reggal 7 inch. It`s still going strong and accurate.
Great to see how much care and precision is involved in machining such huge chunks of metal. This was, for me, one of your best videos yet. You have a great camera operator too!
Hey Perry thanks for the great comment mate we both appreciate it cheers 😎👍
It also goes to show how much work goes into making those great videos, it's not all just shoot, edit and load up. Lots of retakes and getting to camera shots right. I worked on a few big budget films and to get just one minuets actual film time can take ages to produce. Great team at work, thanks
+10, huge props for the camera op! 👍😁
When you think about the amount of energy stored in a 350kg chunk of steel that's spinning @190rpm, should anything break free the consequences would be bloody terrible - smashing the lathe, the part & quite likely the operator...
And nerves of steel, total focus, and patience with the bottom tap! Been there. (OMG, love the radial arm drilling machine!) Cheers!
Most satisfying thread tapping job ever, I'm sure the D11 appreciates the love!
D10T🤣
As young as you are , I'm hard pressed to see such dedication ,& the care and concern and all the times you got past what any run of the mill machine shop would do,no short cuts,original parts ,tips& tricks so none of your repairs come back ! Who taught you the majority of what you know, some only know just enough and cross their fingers & hope & pray ! You sir are the benchmark all others try to be their whole life !!! And I love your bloopers at the end of your videos,and I can see the love you have for your wife and your dog ! Good on ya!!! Keep the vids comming .
40 years a Maintenance Fitter Machinist, seeing some use a pointer to position the drill bit and use telescopic gauges to measure a hole! Brings a tear to my eye! Pity you don't have a vertical borer for stuff that big.🤪 Great work.
Очередной релакс для зрителей, спасибо! :) Алтай смотрит ))
I like the way you mentioned proper preparation or as I call it the 6 P’s in work. Proper Preparation Prevents Piss Poor Performance. Great work.
That's it mate! 😎👌
@@CuttingEdgeEngineering Ha! The British version is better, surely? Proper Planning and Preparation Prevents Piss Poor Performance... 7 not 6!!
Just that part 730 lbs or so? Oh my gosh those dozers are heavy!!! Beautiful job, as you said saving the customers thousands of dollars. Love the videos.👍👍
Seeing all the bloopers makes me realize that it helps you to be so much more vocal about your work, and how complex things get, trying to explain what people don't actually understand because they would need to know how the process works. Happens to me all the time with electronics. hahaha! So kudos for the effort!
I'm so glad you decided to tap by hand, watching guys tap holes with power makes me a nervous wreck. That quite an impressive drill press.
It’s exactly the same at our work, it’s Czechoslovakian design made in China, when the Czechs were communist and friendly with China, a bit of history
Mate, my first trade was fitting and machining, then I did my sparky trade (there were almost no manufacturing jobs in Sydney back then) and became an automatic gate technician, I wish I had stayed in machining every Friday night watching you work. Good to see a fellow QLDer (I've only been a Queenslander for 4 months) doing great stuff, love watching every week.
Welcome to the smart state 😂😂😂 thanks for watching mate always great to have Aussie support
I love these videos. I have 3 male inherited nephews from a parental death situation. I share these videos with them to show them what a “ man’s man” is. One of the three is now a machinist.
Nice. Using the pulling bolt + rattle gun to insert the bushing is nifty.
What I enjoyed the most? The whole damn thing. If pressed, I'd say pulling those sleeves in was my favorite.
awesome mate thanks for watching!
I like how you only make sure the tap start square after drilling the hole, and then tap all the holes in one go at the end. Much more effecient then switching to a spring loaded tap guide for each hole.
I am reminded of that old chestnut that I charge not for the time it takes me but for the experience it I have spent years in gaining. In your case not only acquiring the skills you display but the investment in machinery and plant that make your workshop one of the most complete go to locations for machining and repair. Just great to watch.
Using that blank to center the cutter was a bit of genius. The kind of finesse that takes experience!
WOW, I wish when I was young that I would have had the intelligence that you have. You do awesome work. Very smart young man. Great video as always.
hey Jeff thanks mate
You n ever cease to amaze me with the breadth of your knowledge, you also got immense talent in you hands too. Just a pleasure to watch.
Cheers for the great comment
I have to say that was a real relaxing vid to watch on a sat afternoon(enjoying binging on your older content as I catch up). As you say preparation makes the job go so much easier than not doing the extra work before you start. The dog slot and the outtakes is a perfect touch to these great vids. The 3 of you make the perfect team and making real quality !! Keep up the amazing content..
The absolute size of the parts you repair is mind-boggling.🤯
Pear7777,if you worked in a steel mill machine shop with a 60 inch lathe and 50ft. long you’ve seen some big pieces of machinery
Even though I never have, I'm not, and never will do any machining, especially for earth moving equipment, I'm addicted to this channel! I'll take a wild guess and I bet 95% of the viewers also are never going to operate a lathe. But it's so interesting to watch. I really appreciate that he explains things like the reasons why he goes through procedures and how the tools operate.
hey mate thanks for watching the vids glad they are enjoyed. We did a community poll and about 70% of viewers don't do machining!
I think perhaps a fair portion of us don't do it professionally - I don't - but may have a lathe, welder, drill press, etc. Even my brother-in-law, a banker, has lots of tools and is quite handy.
You know when the bed extension and the face plate are being fitted with you standing on the lathe bed that we are in for some large parts to machine ! I much appreciate how you use precision measuring methods when required by simple jigs etc when it doesn’t matter.
VERDADE bem explicativos, DIFERENCIADO.
As a machinist, I agree completely, especially about his explanations. Over the last couple years I have been teaching adult education trade school programs, and have taken quite a bit from how he explains things. He's a great machinist, and I can tell you there's lots of good machinists out there who couldn't present and explain their work anywhere near as well.

Yeah Karen is awesome with the great camera work. Very smart. What a talented couple !
The camera operator and editor (the wife!) is VERY good! It's not easy to shoot and edit a video. It requires a skill and a lot of work.
I've done a lot of shrink fit bushing repairs. Sometimes it is helpful to put the bushing on your puller and freeze the whole thing. That saves you time and helps keep the puller from heat sinking the bushing. The smaller the bushing, the more it helps. Nice work!
Usually, that gives you about a minute and a half to get it seated.
@@docalexander2853 It depends how much you freeze it. I like to get some dry ice and keep the bushings/bearings in there overnight. I almost never need a puller.
Cusomer:"How much is this going to cost?" Kurtis:"A shit ton."
But not as much as those bastards from CAT will charge!
@@connahjones8178 That's right!
Never user the term "cheap in comparison", try "financially advantageous" ;-) Great work as always, makes my Friday!

@@gorillaau Great idea! Thanks for bringing this to the table! ;-)
@@Churchill250267 No worries. Glad I could be of help.
Yup, the quality of his work is anything but cheap to be sure. I'm guessing it was about 2800 or so vs over 10K for a new part. Plus, when the seal wears out, it's field replaceable. He literally saved the customer 10's of thousands of dollars in the long run. Financially advantageous indeed.❤
You and your wife deserve an OSCAR for your separate talents. Congratulations
As an American, I love the “bananas” unit of measurement. Machining in US Customary units is second nature to me/us, but I can imagine the struggle for the rest of the world. 5.16mm is 13/64th bananas. Lol. Love it! Also, I love the clips at the end with Kurtis frustrated and swearing.
4:27 Me, who is used to wood lathes: "Now THAT is a faceplate!"
Love getting off work at midnight and and starting my long weekend with a CEE video. Cheers from Canada!
Have a good long weekend mate and thanks for watching!
Customer looks at the video thinking, "He makes it look so easy!" Then they look at the outtakes, "Ahh yess, that is the job as I remember it!" Love your work guys.
Love to see the new machine tools (post 1970). And the outtakes? Priceless.
The brick factory I used to work at had a Cat D8, we had to had the final drive completely replaced after a wire wrapped around the cone and worked it's way in to the gear assembly. It was almost as much as a new dozer to get it fixed. a little over $20k for parts & labor. We could've bought a new dozer at the time for $30-35k. Now you can pick them up for $10k. This repair is definitely worth it
I don’t need to watch suspenseful movies; my heartrate elevates seeing those threaded rods pass within millimeters of the machine. 😳 Great video, and love seeing the SO having a pleasant day in the sun! ☺️
This video takes me back to 1964, when I started work at 16 as an Apprentice Engineer. Awesome stuff.
I had to chuckle when you gave the drill size in bananas, then immediately proceeded to describe the tap in inches. Gave me a smile. I like to watch a CEE video daily, even though I am neither a mechanic nor machinist. Best to you all.
Hello Kurtis, Nice work on todays project... I have always thought the labyrinth seal is a very cool design... Well done to Karen for condensing a days working into 55 minutes... See you next week. Cheers Paul,,
Hey mate hope your week has been a good one. Yeah was quite an efforts on editing for this one glad it's enjoyed all the way in the UK! Cheers, Kurtis 😎👍
Dogs are great, aren't they?! Always pleased to see you, never judge you, just glad to receive your attention! I'm glad to see you're doing well, hope it stays that that way for you and yours.
I find it impressive that you can make measurements that are accurate to the point that you can make parts fit. And you do it on a regular basis. All the tricks that you know are learnt and assimilated are from being the God of engineering.
It really gives me hope seeing a younger man with real skills and knowledge. Old hands like me are dying off, good on ya for keeping the craft going
These video's are well suited for technical colleges. They contain so much detailed information about the whole process. It's phenomenal. The explanation segments are somewhat quick though. The amount of technical details you're communicating is too much for me to understand in such a short time, and you speak very fast. You're done taking before I get the message completely. It's well worth to elaborate a little bit more on these valuable technical details
Great explanation, as always the schematic view of part location is a great add. Alway good to see larger diameter jobs being completed with the same precision and tolarances as the smaller jobs. This some times hard to explain to non machinist. Keep up the great work CEE.
Thanks for sharing some feedback and taking time to watch
I love this channel. It's just straight ahead hands on machining and practical, professional repair work. Usually on some pretty good sized pieces that the average machine and repair shop doesn't deal with.
Proper planning, careful execution, and clearly pride in your work. Thanks for sharing, truly a pleasure to watch.
I'm a first year fitter.. your videos are really helping me with my trade! To see how everything I'm learning is applied in a practical sense. Thankyou for uploading it's really helping me out and I'm very interested in working in heavy machinery once I'm qualified cheers!
That was some fine work! Been machining for a little over a year now (late career side-hustle). Understood everything you did - you don't just make things look easy, you make things really clear in these videos. Love the focus on the setup and operations. The slow-mo chip shots are great too.
Man, Giggly's filming is just incredible, great job guys.
These are the most adictive videos on You Tube, once you watch one you are hooked. What a great husband and wife team,(not forgetting Homeless, your dog!) she is a fantastic camera operator and her husband a world class machinist, it's hard to believe that he manages all of this work on his own. I worked as a heavy equipment/diesel mechanic (Florida, USA) over the years (retired now) this is probably why I like watching these videos so much. Keep up these videos, you have a lot of fans around the world judging by the comments!
Homey is family too, because he’s the resident Safety Officer for Cutting Edge Engineering
Great stuff. Thanks for the out takes - appreciate your persistence against flubs and the continued good-humoured support of your camera team.
I look forward to your new videos every week. I notice you're very detail oriented in how you complete your repairs. No short cuts in your shop. Good on you!
Another quality job saving thousands on a replacement. I hate tapping out small blind holes like, just in case
28:56 The "Curtis Fingler Flick" style. When you do that, you don't just think- YOU KNOW YOU'RE BAD ASS!
I love the photography - your close in and I can see everything - perfect - and it's also perfect to see you make mistakes because otherwise it makes the rest of us look like we are - more or less the same as you.
Just fascinating! Watching these huge machining jobs, and the tremendous skill required.
Here in Finland the duo cones sometimes fail because of freezing weather. You run the machine in water or deep snow, water gets into the labyrinth and then the temperature drops and the cones freeze together and when the machine is run again the cones will rotate against the rubber O-rings instead of each other, wearing the O-rings down so they lose their tension. I have seen final drives filled with muddy water instead of oil because of this kind of failure. Nice dog by the way, staffys are the best, so friendly and loving. My brother has one, unfortunately he's getting old at 15 years so he probably won't be with us for long anymore. I'm afraid that chew toy won't last long though, they tend to make short work of those.
You know, Pitties probably love being a dog more than any orher dog! Just hilarious!!
Always impressed how you use the crane to move parts like the chuck or tailstock. They could possibly be lifted by hand but at risk of busting your back; why take a chance. OHS in a one man shop is so important and you set a great example.
As an apprentice fitter/machinist, your tips and knowledge really help me. I’m going to make some of those drill bit punches. So handy and so simple.
Thank you for taking so much time to explain everything. Your work is impressive. You can see your dedication in everything you do and it's paying off. All that new equipment doesn't come cheap. Your progress is a direct reflection of your drive and dedication. Keep it up man!
The amount of skill this guy has is probably lost on most of us watching. You have my respect
I'm starting to wonder how many jigs Krutis has made for handling Cat parts.
More than a few... And less than too many...
Probably quite a few, Australia loves their Cat equipment.
@@HappilyHomicidalHooligan You are probably right. If a jig makes it safer and easier on both machine and operator, do it. It's an hour(???) well spent. I wouldn't want to be anywhere close when a 320kg block breaks loose. Even the shops safety officer will be one of the first out the door should that happen.
@@gorillaau should it happen, then said 320 kg block will be the very first one out of the door... regardless whether door was closed or open. Do not underestimate flywheels.
@@totojejedinecnynick True. I was being a little sarcastic.
