I did this same bearing/gear in a machine much larger. I removed and extended the hydraulic hoses in the center and drove the tracks out from underneath.

You made that look waaaay too easy. Awesome work

My family goes back almost 100 years in the excavating biz, seen it all, very well done.

You made a tough job look easy. What we do is every week or so we attach an electric grease gun to the swing bearing and then do a full 360 while greasing it. We've never replaced one. And of course we grease it every day, but the grease doesn't go right around, that's the problem.

Great vid - and I'm sure it wasn't as easy as it looked there!

I did one of these a few years ago myself on a 307 cat. By far the nastiest, messiest job I have ever done in my life. Disconnecting the swing motor hoses through the tiny access hole underneath the machine leaves nowhere for the fluid to go but down your arms, in your hair, and face. I had an oil catch pan underneath that gave me even less room to work. I threw out everything I was wearing after disconnecting those hoses and it took me three days to get the hydraulic fluid out of my hair. I used rr Ties on top of the tracks and 4 bottle jacks to lift the machine straight up, your method was easier and probably much cleaner.

Great job, letting the machines helping you, a lot faster that way, bet you we're ready for heading home after that one, really impressive work, thanks for filming

always wondered how that part worked, good job.

Thanks for the video. I've a Yanmar b50 that rocks a bit after 7500 hours. I've wondered how to do this job for a while. Impressive!

Whaouh ! Had never seen before that type of maintenance ! Thx for sharing

Cool how that one little gear is keeping it from rolling!!!

You made it look easy.

That was very interesting! Good team work too!

Oh that’s a fun job ! Great job and great use of those cut off logs for cribbage! Whatever works to get it done! Thanks for sharing 👍

Well done lads, an outstanding video of working on site, completing a seriously heavy piece of maintenance, without the need of specialised equipment and facilities. I watched entranced at how this was achieved and loved every minute and learned so much too.. Well done all..

Nice work. Great job using the machines to work on the machines. Bravo!

Well done. You made it look so easy

Fascinating video to a nerd like me. I would have thought a replacement like that would have been about 10X more complicated than it actually was.

Trabajo fino!

This is a super awesome video! I too have always wondered how this mechanism works. Many questions answered in this video. I probably will be dismantling a John deere 35D soon for the undercarriage, Thanks for the insight! New word learned, rotary manifold!

Good job Love the vid

Good to see you capped and plugged the hoses and fittings on the rotary manifold. I know guys who would have left them to collect whatever contamination felt like working it's way in.

we used to do the same with our old O&K in the scrap yard , never had logs , just used 45 gallon oil drums and blocks of wood.

Good Job! You make it look easy!

Fastingating. Thanks for letting us watch! :-)

Very impressive. You made it look easy

Thanks for the video. I learned something today! ;) Really informative and gives you really practical solution to perform this task. You "just" need to know how everything works and that's it.

well damn that was pretty impressive. here I thought a crane would be needed to pick it up.

That's impressive! Well done.

Well heck that was easy , les than seven minutes start to finish lol.

I have been working on 450 lots of time it's so easy work u have done this without cranes.

That was a big job to do on site.....impressive.

Great video. Just goes to show mans ingenuity.

And I thought you cracked the bolts loose with an 8 inch rachet, until the "five foot bar" comment.

Resourceful and cheap! Nice, I like it! 👍

+ skidill you made that look to easy there bud hahahaha cool video as always

Excellent video bro!!!

Nice job guy. Very smooth

Reminds me how I once tightened these bolts on a Leopard 2 MBT.

Cavolo.... sei stato un genio, complimenti, ottima tecnica, nel nostro lavoro c’è sempre da imparare, il motivo per che amo questo lavoro, è perché non si finisce mai di imparare... compimenti !!!!

That was cool never seem that done in the field before

Very impressive 👍🏼

nice job man !!

Well done! I never realized you could pick yourself up off of it either. I never ceases to amaze me how much these machines can take care of themselves. And how such large imposing machines can be broken down so easily with a few (sometimes a LOT) of big nuts and bolts. Hope I never have to do this on my link belt but if I do I guess the biggest challenge may be finding stumps that big!

Slickest way I have seen!!

saved a ton of money

Made an absolute nightmare seem easy. I think I would have sent it to auction. My Deere has the ring bearing zerk in the cab, and if I skip any greasing, its not that one. I consider a worn swing bearing a finished excavator. Your ring gear should have been packed with grease, not water. Made it look easy - the JD book says fill 4 55 gallon drums with cement and set the unit on them with a crane! But it also wants 3" depth of grease around the gear, and that part is correct.

Wow! Nice job. Thanks.

You made it look easy I would have liked to see how you got all the bolt holes lined up. Neat job, It appears you have been to that rodeo before.

Had to drop a super swivel out of a big Hitachi excavator once. Can't remember exactly what model. Dropped it out through the bottom, wasn't fun!

looks like the slewing ring gear, not bearing (roballo or plain?)

What came first? The excavator or the egg?

Мне понравилось!Классно сработано!

This week a Volvo excavator, next week an Abrams tank turret ring thingy! Enjoyed watching this job you have done, I’m impressed! Right I’ll go back to non stop coughing ! Damn virus, take care....Phil

Nice job!! You my friend have guts!

Very impressive

Your dad giving you a hand? I've never seen it done using the machine to lift itself off the car body.

Sure would of liked to see a new or rebuilt bearing for all that work. Oh well they can do it again in a few months

If that was your first rodeo I'm impressed

So, the ring gear is fine? Is it just the bearing surface that is refinished on a huge lathe?

Best presentation, thanks for the video

I once unscrewed the ring of a Leopard MBT. Memories...

awesome video, should do more how to videos haha

👌 Good Work!

Anyone know if it komatsu PC 220 lc3 is a good excavator? And how much would a good price be if it had this bearing replaced in it and runs good just has some links and also has a thumb

great video, learning curve question: Did the machine get swamped as I am not familiar with how watery thin the oil was once you removed the carriage?, only way to learn is to ask. They had to take the gears out to move the burnt buncher they didn't like the speed on the downhill haul:) Thanks for this interesting share sure it was a lot of work.

nice road builder in the back ground

you made it look too easy , good prep work you were ready

wondering if that ring gear is repairable

Gracias por tu vídeo 👌👌👌

Nice job brother

Thank you, I APPRECIATE your video...I Have always done my own work on my equipment and my Swing Bearing is shot, I lift up cab a few inches before tracks lifts, any way I was considering paying for this work just because I had never done one...after watching this it reminded me it’s just nuts and bolts not rocket science and 1 1/2 hours after watching this I had my machine in two pieces...I just need to pick up parts tomorrow and back together...seriously thank you! I saved $1100 in labor my children can benefit from this $$, your video was not for nothing...your saving fellow fans $$

Good job! Amazing watching this

To cool guys . Nice job.

Nice work

Very good job I am sure you have a good business.

Nice job, glad I never had to do one of those.

finally a life long question has been answered, how many excavators does it take to fix and excavator. the answer? 2, the first is the machine being worked on to lift itself up and the second is a smaller on to pull the tracks and the ring.

Which and what size bolt you use to stop the flow of hydraulic oil from The pipe and Rotary Manifold on 6:01

Courage. Great video.

Do you also have to cap the rotary manifold hoses once removed so they don’t spray hydraulic fluid out or they should be fine as long as you don’t that function?

Very interesting to see,never had the chance before! Since the cabin can rotate 360 degrees, how is the connection of the hydraulic lines from the upper part of the excavator to the drive system solved?As far i know,the excavator can rotate and drive at the same time,so.....

Good Job!!

First that was impressive I estimate about 5 or 6 hours. Second is there a seal to keep water out of the turntable?

Damn, nicely done! Did you knock this out in a day?

Would like to have seen more of the rig-up for lifting the top off.

Never seen it done that way wee drop of diesel to rinse out gearbox’s might be a good idea oil looks mighty black

I learned something today

Awesome! You have helped over 1M people fix their own......excavator😃.... If I only had one 😞

3:58 god DAMN. dude has skills similar to a waiter carrying a huge stack of beers at october fest. You gotta anticipate the angle of the dangle. then respond with a stick movement timed JUST right to not enhance the swinging motion but negate it entirly.

If only it were that easy lol. Miss doing that shit tho. Been on the big trucks for a while.

hello sir, i am very interested, what connection allows to turn excavators top ? is it giant bearing or just sliding oiled surface ? watched attentively but didn’t see

So what would make the bearing wear out what i assume is prematurely? Lack of grease?

Good job. How did u line up the swing gear so easily?

磨盤牛油唔打，行機牙箱牙油都唔入牙油，老闆要養部機先得，連偈油，水都唔加，連做保養都唔做？？？部機能替你賺錢嗎？

Nice, I think i would have took the swivel out though to make it easier.

that looked way easy!

hey I know its been a while but do you remember the cap size to the rotary manifold ? and the hose size also if possible thanks !

Very nice...!!!

I am going to ask, what was the actual bearing? The internal ring gear and material acts like a big thrust washer? Mechanically described I am a bit confused on the technology and scale of size.
