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

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.

[@zionfrost]

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.

[@JoeyToth-ti9tp]

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.

[@imkindofabigdeal4308]

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.

[@denjhill]

That company should be very grateful that you work for them. You instill confidence that the job will be done right.

[@lopezlopez7132]

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.

[@brettymike]

BTW, the beautiful filming and editing is just the best! , and I love how she shows your hands on all the controls and dials as well as the cutting. The Master commanding the big machine to do magic seamlessly. Love those giant verniers too! :-D

[@CuttingEdgeEngineering]

Thank you very much 😁

[@mattdoyle9772]

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!

[@brianfalls5894]

Kurtis, I don't know how much you make for doing the jobs that you do but I suspect whatever it is isn't enough. Your attention to detail is on a whole other plane. I love watching you work your magic!!!!! Nothing is ever good enough. If it's not perfection then it's not acceptable. And I love that about you.

[@guygriesmann1234]

I watched this before and still find it fascinating what a person can do with big equipment, experience and talent. Still impressed. I can’t like it again on the thumbs up but if I could, I would. Cheers.

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

[@todd0474]

It amazes me what you can and are able to do. When I was in the US Air Force, I loved taking our parts to the machine shop. I worked in the hydraulic component repair, so I love watching your stuff. I know all about sealing surfaces, and how one tiny flaw, and its out of tolerance.

[@Timothy-lb2vr]

You and your wife deserve an OSCAR for your separate talents. Congratulations

[@realtruth172]

enjoyed watching you work down under from a 77 year old retired trucker my first career was 9 years in a repair machine shop with a lot machine shop training prior to the machine work did some lathe work on a 36" long bed but loved the machine work but i found out that i liked working outside and i dump trucked 39 years but i still miss the machine shop i remember boring out a transmission with a spun bearing that appeared to be junk made the sleeve pressed the bearing race in it was about 24" inside the trani the guy was so happy he hugged me real hard that was done on a kearney & trecker horizontal mill ..

I'm starting to wonder how many jigs Krutis has made for handling Cat parts.

[@HappilyHomicidalHooligan]

More than a few... And less than too many...

[@ks_1111]

Probably quite a few, Australia loves their Cat equipment.

[@gorillaau]

@@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.

[@totojejedinecnynick]

@@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.

[@gorillaau]

@@totojejedinecnynick True. I was being a little sarcastic.

[@moikehunt8928]

Having watched many of your videos I am none the wiser with all things engineering. Regardless, there is nothing more satisfying than watching a master craftsman execute his trade with such command and finesse. Your engineering skills are exceeded only by your partners good looks, camera work and editing skills. Well done both of you and thanks for sharing.

[@teamidris]

I was always impressed with the fix-it kits CAT did like oversize seals. As a design engineer I loved the extensive data sets they had on engines. :o)

[@nickjohns1192]

A CAT engineer told me one day you only check the oil on a cat engine when you don't see any oil leaking out of it

[@teamidris]

@@nickjohns1192 yes, on the old engines you checked the main bearings with a bar under the front pulley. If it was clunky it might need a rebuild :o)

[@fredbrooks1386]

I really enjoy watching a true craftsman working. Thank you! Your skill, knowledge, and work ethic is wonderful.

[@1963uspl]

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.

[@kenkobylka8172]

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!
