I work in a distribution center for a heavy equipment manufacturer, as a quality inspector. Watching these shop videos is allowing me to see where and how all the different parts I see on a daily basis are used.
I don't know why anyone would question you on the tracks but there are all kinds out there and in numbers. This video is telling me to do something as my right drive is weak and needs to be replaced or rebuilt. Thanks for another good one, Mike.
I’ve been trying to figure out how these work inside, and so far this is the best video I’ve seen. Notice the outer planetary carrier spins within the ring gear, but the second stage (inner, closest to the drive motor) planetary carrier is stationary, and the planet gears are the ones driving the ring gear from the inside.
You are an excellent technical instructor and at the same time you maintain humility ....when you mess up you admit to it! Error is to being human. .... That's why I come watch n learn from the best here.
The prop shaft(driveshaft) is a wear item made from inferior material to the internals. They make it that way so if the machine is dead you can easily remove the shaft to get the machine in the trailer.....at least that's what I was toukd by a old-timer.thanks again for the amazing family content.
I bet it takes more time to learn how to work on the equipment than it does to operate it the equipment. My winter goal this winter is to try and get some maintenance knowledge because I have none other than basic stuff. Nice video Mike.
She's ALIVE, just love your explanations on how things work. You would make a great teacher or guest speaker at universities and colleges. Gunner gets more handsome. Stay safe and thanks for the content.
While an old video, it was a Most Informative video, Mike. I'd long wondered if the tracks operated from electric motors, hydraulic or mechanical (direct) drive. NOW, I Know!!
Mike, you would make a great teacher for vocational training school if you ever got tired of sitting in the excavator. It is amazing the engineering of these machines and the abuse/use these machines endure over the years! Thank You for a most informative video, I liked it!
Loved it. Very informative once again Mike. I really like working on equipment too besides running it. That way you really get to know your machine. And when you here a noise you pertty much know what it is. Well some of the time.... Good job DP.
Mike since ur so good a building u should build a camera holder that u can use at ur bench and beable to move it with ease and move it to were u want so when ur videoing u can use both hands. Ur great at what u do. Thank u again.
You're right about that gear oil. It's stomach-heaving stuff. Can't help but feel that drive shaft was a pattern part made from Chinesium. A few years back some of the big aircraft jet engine makers found that pattern parts had found their way into their engines. Scary! One day, when you're long gone and your little boy has grandchildren, he might look at these videos and shed a tear for his old man.
Love watching these shop videos, my '75 JD 410 backhoe just started knocking hard and the oil filter is full of metal. Just ordered a engine rebuild kit and tearing it apart tomorrow! Keep up the good work!
Planetary gears: like the center of our world... what drives us, takes the most abuse. Good catch 👏 👌 on that wear. The fresh lube will certainly help as well. Nice vidja Mike. Cheers!
It amazes me how all these parts do something in all those gears. I love watching you guys work on your equipment but my favorite one was when you worked on your Mack truck.
There is something so satisfying about repairing and keeping the old equipment. I love new equipment. but I feel better when I revitalize the older tools. It's great to see the look on your face when you start it up and see it work like new.
thats what we learn to deal with when we run older metal! but i love that i dont have to deal with any emissions issues with my dozer that i do with my farm tractor and bobcat! enjoyed it! stay safe friend!
Just a tip. Next time you rebuild any hydraulic pump or motor, have a squirt can full of new, clean oil to lubricate all moving surfaces as you re-assemble. When you installed the new Rotating Group (Piston Block and Pistons) the Swash Plate was dry. The lubrication for the Piston Shoes to the Swash Plate comes through the Pistons, through the Knuckle, to the center of the Piston Shoes. Oil under pressure supplies this lubrication. Since this is a high speed, low torque motor it typically runs 600 rpm minimum. When you start up a new or rebuilt unit dry, the Piston Shoes are riding on a dry surface. Since the Piston Shoes are Brass and the Swash Plate is hardened steel, the Brass Shoes lose the battle of what wears first when no lubricant is present. Also rotate the housing to its side. This way the Piston Shoe will not drop out off the Piston. 53 years in the Hydraulics and Pneumatics business has been a tremendous learning curve. And I still have more to learn.
Excellent repair video Mike, great camera work, explanation of the final drive components, and their function. Sweet to see the old 120 back ready for work again! Work safe, enjoy your weekend bud. Doug@ the "ranch"
Great to see 5he 120 back on her tracks !! Nice bit of help from your boy. That second one that you put in looked a much better fit at the top as well the much better fit than the paper thin splines!. Should last you a good few more hours. Take care and be safe and see you back at the retaining walls! All the best Graham🇬🇧🇬🇧👍👍
I really enjoy the shop videos, especially when there's something to be learned. You seem to enjoy wrenching, even though it means something is likely "broke". thanks
Well done. I am proactive like that as well. My father says I waste money “hunting boogers” lol. We argue a lot lol. However I believe I’m saving time and money.
I haven't seen you smile like that since they Sunday Hyundai left you used to hit every day for the big smile on your face. Did you ever hear from anybody I remember you put a dirt perfect sticker on it and we're going to try and track it I was curious keep up the good work and a good videos. It beats the hell out of me how you can get good workers all the time. I guess the countries difference in the big city LOL peace out keep up the good work
"...test out the old light on the new Deere." Wow, I thought it was the new light on the old Deere, LOL! Good to see life in the 120 again. Thanks for sharing.
It sounds like the 120 is a dear thing 😉 one of the type before the electronc stuff becom common Great to see it running like a Deere Take care stay well
Your Mack training has really paid off for you, I would not have a clue where to start on this, and to boot I would probably end up with a box full of bolts etc. !!!! Good too see Gunner helping out, even if it was only for a short time, too busy driving his cart around!!
great video ,,2 things i seen when you hooked the track back together the pin was it installed all the way ?? and the 2nd thing ,, when you repaired the light you left a wrench on the boom ??? dont know if you left it or got it off camera .. that is how people loose tools ... or get hit on the head .. like when people leave a hammer on a step ladder .and you move the ladder ugh beep and a few choice words later ... keep the videos coming there great ..
Good tutorial on final drive inner workings. There is a large main bearing in this assembly that deserves attention. The adjustment is critical because if it is not within spec, the metal faced seal that keeps the oil in the gear housing could begin to leak. There is a large nut behind the primary planetary gear set. This nut adjusts the preload on the bearing. My final began seeping a little oil so I tightened this nut and it stopped the leakage. You can do this without splitting the track.
Good luck getting your excavator final drive back together Mr Dirt Perfect
Great video Mr Dirt Perfect and Matt
Great job fixing the final drive on the excavator Mr Dirt Perfect

It is
Love your shop videos
Thanks
Must be a great feeling to get the old girl working again! Great work Mike!
Yes it was
Great video Mike y'all have a great weekend and stay safe 👍

These shop videos are almost as awesome as the dirt flogging videos! Thanks for sharing!
That Campground Guy
Thanks Michael
@@DirtPerfect I managed to adjust my profile.. now for a video!
Enjoyed this video bro. Safe travels
Great video....thanks for posting
Thanks buddy
Glad ya got the JD goin!!!
Like the shop sessions DP.
Thanks
What an informative video. Gunner gets quality time with dad. Stay safe
Thanks Bruce
Good job Mike.
Thanks

Another awesome video!
Thanks
Nice to see the 120 with her shoes back on. Can't wait to see her get back to work! Great job. Thanks!
Thanks
I'm so glad I'm not the only boring dad in the shop. It used to hurt my feelings when I was younger
Those tracks are on backwards🤣 Great informative video!
Glad to see her going again!
I have been wanting to see that done since I got my mini excavator thanks for putting that on here.
Thanks
fantastic job.loved the way you explained the final drive gearing
Thanks
Great Video
Wow! YOU MADE THAT LOOK SO EASY. I think I will keep to my job of teaching Middle schoolers that is a lot less confusing.
Thanks Brad

Lots of knowledge on this repair. Gunner is getting quite a lot of education-he knew when it was time to play !!
Thanks John

Great video! You passed the mechanics test with flying colors. You never once asked for a "bigger hammer ". Way to go.
Thanks buddy
Bad your boys smart to supervise at work
Interesting Job Good work
Thanks
Good job you know what you are doing D P ace 👍
Good for you!
Thanks
Love your repair videos Mike
Thanks buddy
While an old video, it was a Most Informative video, Mike. I'd long wondered if the tracks operated from electric motors, hydraulic or mechanical (direct) drive. NOW, I Know!!
Glade you enjoyed
You know you got to have man behind the scenes helping with repairs. But it looks like you knew what you were doing. Liked watching Gunter help.
Thanks
👍 Somebody's doing his happy dance!
Glad to see the 120 back to work fancy braking it in the first place love gunner helping you out making shore you doing it right lol
Nice dash WOW!
Good job Gunner!!!... Pickin up the slack. (y).. :)
Mike, you would make a great teacher for vocational training school if you ever got tired of sitting in the excavator.

Love the shop videos 👍👍
Thanks
Another great video. Makes me think I can rebuild mine when it take a dump.
Awesome that you got your baby fixed
Thanks
Enjoy watching you repair the equipment yourself. Not only saving money but learning so much about your equipment.
Thanks

Wow you got a smile on that one

Its good to see people who know how to fix their own machines well done DP 👍
Thanks
I think you can’t wait till Gunner is a little bigger and he’s on the job site with you. I can hear it in your voice❤️👍🇺🇸
I am constantly amazed at the breadth of your knowledge of these pieces of intricate machinery. Keep the videos coming.
Thanks William
Always love the shop videos! It’s all part of the job and I think it’s cool you do your own work on equipment!!
Thanks

Thanks
Great job Mike. To see it all go back together is amazing. Thanks for sharing 👍
Another outstanding job well Done Mr. D. P. .
No matter what, that gear oil can't possibly smell worse than that skunk's spray did 😝
I don't know, those two smells are horrible, not sure which I hate more
The smell of burnt transmission fluid mixed with metal and clutch material is pretty close to old gear oil. 🤮
Looks like you the first Brake Disk (and the others) that you installed @ 6:23 was off a couple of teeth. Love your channel. Cheers!
I really enjoy the shop videos, especially when there's something to be learned. You seem to enjoy wrenching, even though it means something is likely "broke". thanks
Lol thanks
The smile on your face is like that of a new dad in the delivery room!!
😁
Nice job
Thanks
Really good job. Skilled work.
Thanks
Well done. I am proactive like that as well. My father says I waste money “hunting boogers” lol. We argue a lot lol. However I believe I’m saving time and money.
Always entertaining!! Good stuff1
Thanks
Yea Gunner helping Dad
Nice 👍 job
Thanks
Poor Maggie. She still showed up to sweep the floor though. What a trooper!
Good morning Mike. Well your baby is going again. Can't wait for your next video to see her working. Take care and don't work to hard.
Thanks
I haven't seen you smile like that since they Sunday Hyundai left you used to hit every day for the big smile on your face. Did you ever hear from anybody I remember you put a dirt perfect sticker on it and we're going to try and track it I was curious keep up the good work and a good videos. It beats the hell out of me how you can get good workers all the time. I guess the countries difference in the big city LOL peace out keep up the good work
Lol thanks
U-max excentrik! Won lots of races on one of those ol karts
Nice to see those safety crocs.😁 Another tip is to fill through the vent hole so it's easy to see when it comes out the level hole.
I hope you still have the 120 come the day you retire. I think you have feelings for the old piece of iron!!
Thanks
"...test out the old light on the new Deere." Wow, I thought it was the new light on the old Deere, LOL! Good to see life in the 120 again. Thanks for sharing.
That gear looks like a big ole clock. Like the way you explain how things work and go back together.
It sounds like the 120 is a dear thing 😉 one of the type before the electronc stuff becom common
Great to see it running like a Deere
Take care stay well
Your Mack training has really paid off for you, I would not have a clue where to start on this, and to boot I would probably end up with a box full of bolts etc. !!!!
Good too see Gunner helping out, even if it was only for a short time, too busy driving his cart around!!

So that is how a final drive goes back together - its not magic after all! Thanks for the great video Mr. DP!
Lol
