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 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.
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.
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.
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 $$, your video was not for nothing...your saving fellow fans $$
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
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..
Thank-you! hopefully this has saved many people thousands of dollars doing it themself too.This cost me basically nothing . I had bought the bottom half of a same machine that had burnt but only had 860 hours on it. I bought for the track parts cheap,and the bearing was just a bonus.
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.
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!
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
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 !!!!
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!
+skadill Yeah I was thinking that or the timbers like you see used to drydock ships and such. Regardless, cool to see it can done this way. I'm not sure I can free spool my final drives though. I've never opened up the motor to see what the insides look like. I guess if I just disconnected the hydraulic lines it would free spin at worst case.
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
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?
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.
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
How did you use the arm without sucking air into it with the recirc disconnected? I seen you capped the one side but how did you get flow back into the system using the arm?
You can never add enough grease to this unit . We had an older cat 320D and i put in a waste oil and grease mix into a welded bin and attatched a air connection so i could pressure the container and had 2 pipes going dow into the ring gear itself . Every so often we would then use compressor r to squeeze more oil and grease into it and it lasted 10 years afterwards but messy if a hose went on the swivel unit . Thise were the days 6am to 9pm for pennys
seen lads smear gerase all over the teeth of the s ring gear when they put it on before they drop the house back down on the gear .........also u can grease through the nipples on the gear rotate 20 degrees and grease again till u get around all the way ............
We did a few of these and you use 3 longer bolts and put blunt point at other end and lower down on the 3 bolts and then manouver the ubdercarrage with another machine front to back or side to side and after a bit you get the 3 bolts lined up and then fjnishe the rest . Takes a bit of patience
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.
the part he lifted off is the bearing, big balls that fit between an inner and outer race, they load through a plug in the side, at least on the ones I've done...after you've done a few really a pretty easy job....
Why is there no hole to evacuate water and debris collected in the ring's inner diameter ? All this water and mud is certainly not bearing or gear friendly.
there is/was.It is a light guage plate held on with 2 small bolts,but you have to take the belly guard/plate off under the rotary manifold to get at it.Didnt know it was full until this time.
water got in because the rubber boot cover around the rotary manifold was torn up,but yes,it wouldnt hurt for moisture to be able to escape.this machine got sold right after this.Was machines ago now.
The reason they don't drain is for use in urban or construction areas where grease residue leaking out is not desired and they are also designed to be mostly closed system with just a condensation drain so that dust ingress is minimized (why the hole is proportionally small). In the forestry industry this doesn't really matter however mud and dust protection is a plus. As a side not during normal active use with regular slew ring greasing the water never really has a chance to contact the metal and cause corrosion as the slew ring is a grease pit of doom and usually has about 4 liters+ (1 gallon) of grease stuck in there after a few years of operation.
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 work. Great job using the machines to work on the machines. Bravo!
Halo
That was very interesting! Good team work too!
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.
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 👍

I have been working on 450 lots of time it's so easy work u have done this without cranes.
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.
Well heck that was easy , les than seven minutes start to finish lol.
he actually did have it done by first coffee lmao

So, the ring gear is fine? Is it just the bearing surface that is refinished on a huge lathe?
Nice job guy. Very smooth
Reminds me how I once tightened these bolts on a Leopard 2 MBT.
that was really smooth, so the gear is considered the Bearing ? or is the actual bearing another part?
Did u find out what the answer was? Mr. Bond
@@ferenzi7741 I did not
And I thought you cracked the bolts loose with an 8 inch rachet, until the "five foot bar" comment.
Which and what size bolt you use to stop the flow of hydraulic oil from The pipe and Rotary Manifold on 6:01
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
Awesome! You have helped over 1M people fix their own......excavator😃.... If I only had one 😞
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?
Excellent video bro!!!
That was cool never seem that done in the field before
Very impressive 👍🏼
Wow! Nice job. Thanks.
Halo
looks like the slewing ring gear, not bearing (roballo or plain?)
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 !

Мне понравилось!Классно сработано!
Gracias por tu vídeo 👌👌👌
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
saved a ton of money
What came first? The excavator or the egg?
+ skidill you made that look to easy there bud hahahaha cool video as always
Slickest way I have seen!!
How did you use the arm without sucking air into it with the recirc disconnected? I seen you capped the one side but how did you get flow back into the system using the arm?
All the lines to the swivel are capped off.
Machine will function normally with all other controls.
Very impressive
👌 Good Work!
So what would make the bearing wear out what i assume is prematurely? Lack of grease?
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
I once unscrewed the ring of a Leopard MBT. Memories...
Nice job!! You my friend have guts!
No,just cheap and brave enough to save 8 to 10 thousand dollars
That gear is the bearing?
My greatest regret is that I have but one "like" to give
Great reply, I feel the same.
Good one 🤣🤣
To cool guys . Nice job.
How much grease did you put back in? Ive put 40 tubes in my EX200 and doesnt seem to be enough.
@ike fun lol
You can never add enough grease to this unit . We had an older cat 320D and i put in a waste oil and grease mix into a welded bin and attatched a air connection so i could pressure the container and had 2 pipes going dow into the ring gear itself .

Thise were the days 6am to 9pm for pennys
How did you grease the swing gear?…before you set the machine or after you bolted it down and grease through the inspection plate?
seen lads smear gerase all over the teeth of the s ring gear when they put it on before they drop the house back down on the gear .........also u can grease through the nipples on the gear rotate 20 degrees and grease again till u get around all the way ............
Very good job I am sure you have a good business.
Haloo
Did that have a bearing in there?
how did you get the new ring and gear to line up again?
We did a few of these and you use 3 longer bolts and put blunt point at other end and lower down on the 3 bolts and then manouver the ubdercarrage with another machine front to back or side to side and after a bit you get the 3 bolts lined up and then fjnishe the rest . Takes a bit of patience
Damn, nicely done! Did you knock this out in a day?
Good job. How did u line up the swing gear so easily?
You can just take it off and clock it last if it is a big problem to get to.
Nice job, glad I never had to do one of those.
How much do you pay for a used bearing instead of a new one?
Nice work
you made it look too easy , good prep work you were ready
I am going to ask, what was the actual bearing?

I expected to see roller bearings somewhere. Is the bearing just flat steel against flat steel with grease in between? Thanks.
There are balls inside. The inner geared ring is stationary. The outer ring rotates.
@@troybolton4055 Keep them greased, thanks!
nice road builder in the back ground
I learned something today
Your dad giving you a hand? I've never seen it done using the machine to lift itself off the car body.
+Graveltrucking Borrowed a neighbor for a few minutes
how many hours did you get out of the old swing bearing??
only around 8 or 9 thousand hrs,think one of the race car drivers that used it for a while beat on it hard.
Courage. Great video.
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.
+Powder River The bolts all line up as long as the two small line up dowels fall into place,which wasnt any effort.

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？
How difficult was it to line up the bolt holes?
Easy,the turntable spins,theres line up dowels
First that was impressive I estimate about 5 or 6 hours.
Second is there a seal to keep water out of the turntable?
There's a dirt seal. Our mechanics are mad bc of the battery operated grease guns having blown all these seals out.
