Good to see you guys marking your bolts that are torqued even if you are going to paint over it at the end you guarantee you won’t miss any great work guys thanks for sharing
You rock, the torque I referenced was the long extension, According to the instructors in the AIR FORCE when I was IN, MY INSTRUCTOR SCREEMED HOURLY ABOUT log flex torque #s. (in the very early 70s) And they made us check the extensions daily for torque flex. But we may have a lot better steel now. love your content, keep it up. thanks for getting back to me. Have A great day.
Thanks to Casey, when he delivered the service truck, this channel is phenomenal. The different aspects of the different pieces of equipment is great. What's the weight of that final drive.
Hay mate just some things I’ve noticed as I’ve built plenty of these the duo will not last long as there should be a mud ring the goes on the spindle underneath the duo to stop mud build up and also when u set the bearing u should also rotate the hub as u do it to correctly seat the tapered roller bearing still a good video just thought I’d let you know
Hi! Love the channel and the content you guys produce! By no means throwing any hate but I noticed the last bit when installing the outer cover and the struggle of finding the correct torque spec. Been there a few times before with cat equipment! I’ve found if you find the bolt p/n in sis it gives you the correct bolt diameter. Often times you can search the bolt p/n in sis and it will give you the correct spec. For an akt serial prefix that bolt p/n is 8T-9400, torque is 516 Lb Ft listed under the “specifications” section for the final drive in sis
What you doing is thump up.i work in fort-McMurray on time with fluor and big dozer komatsu under rental broke down we this dozer back work due built pads huge cranes so we found wreckers in usa rebuild in house parts with OEM.i send private jet pick up parts yes.the dealers said take couples days well I got in 24 hours on shop floor.this video show people down time huge machine tied down lots around.thank you video calgary alberta canada
Great video. I would like an explanation of how it works on the dozer. I understand planetary gears but confused with the orientation. What is the torque output of the drive? How expensive are the parts i.e. price range? What does CAT charge for a rebuild? Do you know what symptoms it showed to needed a rebuild?
I'll take a stab at how it works: The spindle shown @1:16 bolts to the side of the dozer chassis remaining stationary. The outer hub rotates around the spindle. Inside the outer hub is the stationary reaction hub which is mounted to the spindle end. The axle stub passes through the spindle center & splines into the first sun gear installed @13:25. This narrow sun gear causes the first planet carrier (13:30) to rotate within the reaction gear. This first planet carrier drives the second, wider sun gear. The second sun gear drives the second wider planet carrier (15:32) which doubles as the outside case plate. This case plate is bolted to the outer hub causing it to turn. The track drive sprocket is mounted to the lower shoulder on the outer hub. So in short, the power comes in the center via axle shaft, runs through two stacked planetary gearsets (one narrow, one wide) and exits via the outer faceplate to turn the outer hub with the large sprocket. His previous video shows a similar (this?) unit being removed from a donor machine.
Question on torque #. Did you find out how much extra torque needs to be applied for the extension. ( Longer extension more torque is needed even if it is a few #) Even if it is rated for impact, it will twist also. At least I was told that in the Air Force????
In this case, torque in = torque out - the extension would add a tiny bit more rotation of the wrench due to the twist you mention but the torque would be the same. Yes there could be some perceived wind up due to the extension absorbing some of the input energy but the torque is the same. Impact wrenches impart energy differently and the torsional properties of the extension come into play- that's how "torque sticks" work (uniform input torque with differing cross sections to yield different output torques).
I hate being that guy but standing/working underneath such a heavy piece of steel is not a good or safe idea. OSHA would have a field day with how you rebuilt the final drive. The drive should have been supported on a stationary device, IMHO. BTW, I was crushed by a malfunctioning skid loaders bucket so I take safety very seriously as you should. What might your customers think of such unsafe practices? I mean you no disrespect of any kind. I'd hate to see anyone hunt or Worse, trust me...
Sorry sir. You are an partseller with quarantee! Andrew is an home owner repair guy. If he would have to buy all the specialised tools to do the job? I see other you tubers using hammers and rods. Why not comment on them. I am a quallified marine engineer. At this moment i have a car with warning lights that only the ,,dealer,, can solve. They charge 400 for the same service that another qualified garage(only not branch) wants 185 charges. But the light can only be ,,dissolved,, by dacia. But then the engine has to be flushed etc etc. And as part of the service we put a new filter on the bill but put the old one in this way that the levers dont function. Please dont go that way. I love youre content but dont lift yourself up by getting someone else down.
@@kennethbrown8723 yes i had the same. I live in a part of the world where we speak directly to people. If Quinten has some advice for andrew why not comment directly to him in andrews post?

Hope we get to see more rebuild great job guys

Enjoyed watching you and your team rebuilt this outdrive!
Watching this rebuild perfectly explains why heavy equipment cost so much!👍👍👍

I love to see rebuilds like this!
i liked everything other than painting the flange the segments mount to.
As someone who loved building anything with gears I truly loved watching the rebuild of that final drive. I never rebuilt anything that large.
Thanks to Casey, when he delivered the service truck, this channel is phenomenal. The different aspects of the different pieces of equipment is great. What's the weight of that final drive.
A thing of beauty is a joy forever!
Do you send a copy of the rebuilding video to your customers? Ill bet they are impressed. Keep on sending the great content. Bill
It was interesting to see the different layers of gears mesh into place with each other as you were lowing them into place.
Nice job.Great attention to detail.
Great video and great work. Very informative. I never knew that there were that many parts inside a final drive. I have never seen the inside of one.
Hay mate just some things I’ve noticed as I’ve built plenty of these the duo will not last long as there should be a mud ring the goes on the spindle underneath the duo to stop mud build up and also when u set the bearing u should also rotate the hub as u do it to correctly seat the tapered roller bearing still a good video just thought I’d let you know
Good job 😊
You need to put a tag on it, saying no oil.

Good description of that seal on CEE channel. Lots of Cat machining. Steve
Great video, thumbs up, that is not your first time doing that, thanks for bringing us along, I do not see Casey anywhere
Very cool. Thanks for the video
Great videos, how are the power strokes coming?
Nice job 👍
Good Job 👍.😊
Casey might need you to fix his truck. 👍😀
cool stuff
What you doing is thump up.i work in fort-McMurray on time with fluor and big dozer komatsu under rental broke down we this dozer back work due built pads huge cranes so we found wreckers in usa rebuild in house parts with OEM.i send private jet pick up parts yes.the dealers said take couples days well I got in 24 hours on shop floor.this video show people down time huge machine tied down lots around.thank you video calgary alberta canada
Expensive shipping 😬
When you for fluor you don't mess around with job 2000 men and woman you let sit and wait.the jet paid by himself serious.
Doing work to a quality that you can put your name and reputation on is just so rewarding.

Love the channel! Wondering whats the cost of that part ?
More than 30k so far on the final drive
Dont use impact or anything that rotates bolts with speed when using loctite, the inertia force will undress the loctite to all over inside the thread
Is there quite a bit of difference in price for the rebuild versus new, thanks 😊
Watched a lot of people work that big o ring in with a screw driver
All far east , ( duro cone)?
What is the oil type and volume.
I could use this as a transfer case for my Jeep.
I have put 30 or so in with out your pink little installer on D10 and D11 and cat scrapers never leak but if you have one use it😅
how much of what kind of oil does that take?
Strong work guys if yall hiring holler at me hahaha
That's no 1/2" bolt. More like a 7/8" bolt.........
how much does one of those things cost
Hello
garage door ????
Why do you call a bearing a cone?
It shape like cone. There other types of bearings - ring bearing, ball bearing
You might want to change your password now! Hahaha!!
Andrew "camatra" doesn't do anything like your supposed to. bwhahahahahahaha
