PC200 Undercarriage Replacement
ฝัง
- เผยแพร่เมื่อ 25 ส.ค. 2024
- After about 7800 hrs, my undercarriage is getting tired. Rails are worn through to the pins, a couple rollers are seized, and everything else is close enough to done that I decided to replace it all. Along the way I got a few videos of a couple parts of the process. Wish I had gotten more footage, but I was on a timeline to get it done between jobs. The machine is a Komatsu PC200-6.

Chrome sockets on an impact you naughty young man
Worked at Texas Welding and Press in the 1960's and we did it much differently than you all did. Generational thing I guess. Lots of sledge hammer work with track press and welders on the job for rebuilding rollers, idler, replace/build up sprockets. A young man's game for sure. Thanks for the video.

This was My first job man... So nice to watch and remember
Deyvid Salazar I’m learning, replace buckets and cylinders
If you're going to use a cutting torch then burn the nuts off so you don't damage the pads.
Also try using a 1" impact wrench before cutting the bolts. I have a 250 Litre Air tank which suits the job.
97% of the jobs I do my air gun loosens the bolts.
I've got a 1" Aircat 1992 impact wrench that loosens 20mm bolts & slightly bigger diameters & a 3/4" 1770-XL for bolts 16mm & less.
I have a guy that assists me & we usually do a Pad Swap(roughly 84 shoes), 2 new chains, 4 top rollers & 2 Sprockets in 8-9 hrs but we're non stop from start to finish excepting the occasional swig of much needed water.
Cut the music
Good clip, suddenly I had an attack of vertigo that caused me to stop watching it. And the music was cruciating.
I'm just curious why you're turning your videos into music videos ...look at the context of your videos music has no place.
love the open air cab
You get a much better feel for the weather that way..😂😂
Help with the procedure of installing full undercarriage
Kelly nice video thanks for sharing was suggested to me by TH-cam must be the recent comments
Glad you stopped by. Thanks for putting up with the ridiculously shaky video, and the "terrible music"!
Thanks for posting. Helpful info
You're more than welcome
You need to fire the cameraman it would be nice if you would have actually showed us how to put these parts on.
Nice infomation ☺️☺️👍
As a retired welder I have to tell you you need to go back to school and learn how to set up a torch.
Your job would have been a lot easier had you set the torch up correctly.
I had a 1989 PC 200..komatsu motor..grey market..Humboldt County California
It's good but leave the music out
i second that, music was beyond awful
I turned it down.
The sound of those treads rolling was music
Agreed- the video was very informative. The "music" was terrible and detracted from the content. I turned it off.
Halo
How to install the idler
We can supply with pumps,valves, motors, reducers, reducing boxes of CCHC brand,for your excavators, loaders and rollers,from Shandong China.
She got some new shoes 💯
Music is great........mount camera on a stand.....I got sea sick watching
Me gusta..Mantenimiento y Operador Maquinarias Pesadas...gracias por la informacion.............
De nada!
05:06 is there a reason that the mud is left there? So much work, Restauration, cleaning but why always only this partly cleaning?
where is the air greaser for track tension
My komatsu pc 200lc_8nl has a totally hard start problem...what could be the reason.......I replaced with new injectors,new priming pump,and a new rail pressure sensor : right I got some change immediately but after a month the problem still persists.....I need help and advice please....thank you
Sorry, no idea.
Valve adjustment
Good video. When you pumped up the chain you left a lot of slack?
If ya like the music, turn up the volume, if you don't like the music, turn down the volume.
My method is to pull the pads while at a comfortable working height, meaning while the rails are still on the tractor and stack the grouser side down. Cut the rails, replace the rollers, sprockets and drive gear. Roll the chain on, lightly sand off the paint from the rails and the pads that are grouser side down. Throw pads on at a comfortable working height and install 320 nuts and bolts.
I have some tricks along the way but that's the basics.
Thanks! That's some real world advice right there. Greatly appreciated!
@@kellydklassen I forgot to add that I liked the way that you pulled the rails under. I usually just use another tractor or a truck but if nothing is available or space is limited I'll keep that idea in mind for next time. In fact, I think the next undercarriage I will do will be on another PC, but this will be a PC120. Stacking the pads on a pallet is really handy if you have a forklift available. Especially if you don't have a young buck around to do the lifting.
Very interesting video I like it.
How many hours do you think this took you? Looks like 3 guys helped?
Who cares how they did it the important thing is it's done and it's working.
Why didn’t you show how track was joined up with master pin
Hey, I liked the video perfect or not, thanks a lot.
Thanks!
I had a 94 case 9020. I sold it with just under 10,000 hours with the original bottom, which was still serviceable.I also had a pc200-5 with 17,000 hours, it was on its second bottom when I sold it and still serviceable. A friend of mine has a 200-3 and a 200-6. He replaced just the chains at 13,000 hours. I'm surprised that your machine needs chains so early. Do you work in a lot of sand? Rock?
Yes, lots of hard ground and rock, and mud packing into the undercarriage. And lots of rain to make sure it rusts while it's not working too.
Between the bad music and the poor camera work I had to look for something else. yuck
good work
Thanks Mike
donot cut surface nut of plat hurt the plat
Get rid of the music. It's terrible!.
Try the mute button. It works great!
Removing the music is even better!
It's a free world. Don't like it - move to China or Russia.
@@kellydklassen WTF!!! That music is 100 times louder than your voice!!! Face it you fucked it up.
What did it cost.
One question Kelly Klassen, how did you install the master link? Did you have to have a pin press to do it or anything.
I'm trying to remember, but that part's a little vague in my mind! I see in the video that I've got a sledge hammer and also an air chisel. I'm guessing from my comment that "a little bit of brute force worked" that I probably tried the air chisel and then ended up pounding the pin with the big sledge hammer. They make big fancy specialized presses for pins that the big shops have. I seem to recall that I called a couple local smaller mobile service outfits to see if they had a press and if I could hire them to come do the links and they said they just used a sledge hammer.
I was surprised you didn't replace the sprocket while you were at it. Or did you and I missed it?
Yes and no you didn't miss it. I replaced the sprockets previously so it never made it to the video.
@@kellydklassen Ah, makes sense! They looked to be in pretty decent shape so I wondered :-)
@@truthsmiles
Yep, they were in pretty rough shape before!
❤
cut the grouser bolts chain side, chains going for scrap anyway, will save you a heap of time ant the grousers wont get damaged good work tho .
Crap. Where were you guys BEFORE I started??!! Awesome advice, wish someone had told me that earlier.
#TeamWork
Yeah I was thinking, woulda sucked if the guy running the torch would have cut into the grousers by accident..
@@kellydklassen 5 years too late, but there are benefits to doing it both ways. By cutting the nut off, you save yourself a headache from gouging the tops of the pads with the torch. Downside to that is depending on how snug the shoulder of the bolt is against the chain and pad, it can be a pita to get the rest of the bolt out. Sometimes a half inch impact will be enough to just spin them out, otherwise you're in for lots of pad-beating.
The nice thing about cutting the bolt heads instead of the nuts is that the pads come off super easy almost every single time. Few taps and it pops right off.
It also might be worth looking into bringing your tracks to a track shop in the future. I know labour rates can be outrageous, but I have small tracks like these in and out (both sides) in 10 hours total. Makes it a whole lot easier when you have an electric wtc track torque wrench and bench in front of you + a skidsteer haha
Do you hear music
I would have tried rattling those pad bolts loose with a 1" drive impact before fuckin around torching them off, but oh well
these bolts will never come loose no matter what u try. they did it right. no fucking around and cut theme right away.
Have you ever used a 1" impact? With a proper sized air line? Those pad bolts would come loose like fuck all
Pc 200-6
Yes..Chào em
Camera is all over the place! Very hard to watch! And lose the music!
Most of it sadly is impossible to watch, even with the sound down. Shame, it looked as if it could have been quite interesting.
Actually the music was far better than most, especially that techno crap.
Talk about a shaky cam?
Sorry Bud, I work for a living and have bills to pay. The job comes first ALWAYS, videos second. I just thought I'd grab my phone and record a little while I did it. Before I started, I had done some looking around on youtube and didn't find much, so figured I'd post up whatever I managed to get.
When we watchers become spoiled with a tripod camera and near perfect sound and such, then see a video that shakes, well it was a knee jerk reaction. by no means pay attention to my silly comment.
LOL. No worries! There's some pretty amazing work going up on TH-cam for sure!!. One day I'll be rich and be able to hire a camera crew. For now, it's just little old me and my lousy phone camera!
Sorry but video is next to impossible to watch with camera mounted on someone head and POV changing faster than a hummingbird flitting around. Gave up watching and I really am interested in this type or work. Please use a tripod and back the camera back so we can see the job being done in full frame. OH yes the music just plain blows.
plllz what is Back ground music
I believe I used Dark by Breaking Benjamin, and Countermeasures by London Six Echo
Kelly Klassen 👍🏻thanxx
Another video ruined by bad music. Unwatchable
put some paint on thread of pad bolts keeps them tight god burn bolts on chane side and stand her up to get rollers off dont b killing u self
The music is just awful!
Do you have a part number for the top rollers?
For my machine, I believe it was carrier roller: 20Y-30-08030

No prob, that was easier to look up than I thought it was going to be 😁
Ive been asking a price for a package like you got and no one can give me one. I have a grey marker machine but it’s still a pc200lc-6
@@davidmorrison3100
Grey market shouldn't matter at all for a Komatsu. Sorry to hear you're having trouble. I am lucky I have a couple good suppliers that have taken good care of me even though I don't do a ton of volume. Where are you located?
SQUEAKINESS IS GONE. YOU HEAR THE MACHINE SQUEAKING WHEN IT'S MOVING ON OTHER VIDEOS AND THAT SQUEAKING IS METAL ON METAL WITH NO LUBE. PEOPLE WHO OPERATE EQUIPMENT DON'T UNDERSTAND THAT, THEY THINK NORMAL WHEN THEY HEAR SQUEAKING.
Cut the music...
Would have been lot more instructive with the camera on a solid stand. Instead of a head cam. Sorry.
you can do without the music
call that crap music
Doesn’t look like you guys cleaned the paint off the mating surface between the pads and chains? You will be retightening those pads a few times before they stay tight I bet
No, we didn't clean off any of the paint. Haven't had any problems though in a year and a half since we did it. That's a good point though.
Mad Man Marine stop
Tadas G stop what?
@@Mad.Man.Marine Evidently you should stop giving good advice. I got lucky and learned that lesson on a cutting edge. I think I tightened it back up 3 times in 2 weeks before it stopped haunting me. It was on the loader of a backhoe so it was not hard to access. But it was still a valuable lesson learned!
tdej80 ya. I’ve just always been told if you want it right and tight it needs to be metal on metal.
How much did that cost
I put about $30k (Canadian) into it
not the quickest way to do it.
first cut the old chain and remove the track pads, then place the track pads on the new chain whilst on the ground leave 4 track pads off to assemble the chain on the excavator its way easier then doing it on the excavator
Its better to cut the nut off on rail side so you dont mess up the shoes
That's a great suggestion that a few people with way more experience than me have mentioned. Wish I had thought of that before
I work on tracks everyday. I learn from others and pass it on when i can.
done that a few times now. cat 235, d5 and a hitachi EX100. track work is so fun. not
I am from Iraq and I have experience in heavy equipment and would like to go to America. Can you help me?

Why do people add music to their videos? Just don't do it!
nice hai bro
music toooooo loud ....
first timers i see after the guy holding the torch, cut the bolt, why damaged plates will come loose 100%, cut the nuts chain is scrap anyhow.
Johan Mulderij
That's a way better idea. Why didn't I think of that!? Next time... Thanks!
yeah, did several chains, >50
Also your chain lays on te wrong way, normal busing enters sprocket first, pin turns in busing save sprocket and lesser wear on your under carriage. know a lot had an old mechanic who learned me the ins and outs, now i even overhaul hydraulic pumps and diesels, work for a Liebherr service center
One inch air gun is even better, faster and cheeper.
Horrible music
Wow you have caught a lot of shit! I used to be a heavy equipment mechanic blah blah blah. I did used to be a heavy equipment and everything you did was not perfect. But you were working on your own equipment to save a few bucks. At the end of the day the job is done and you have been using the machine without problems related to the work you did. People wonder why they roll up on videos where the comments have been disabled. If people want to give pointers it is great, but there is no reason to be rude or insulting!
Yah, no kidding!! For some reason everyone seems to think it's really important to share that they have a different taste in music, and that there's better ways to do things!
This was my first undercarriage job and I was learning as I went. Before I started I did some searching and hardly found any videos on the process. As I was doing the job I grabbed my phone to grab a few clips for myself, more for my own records than anything. As an afterthought, I threw it up on TH-cam thinking that maybe someone else one day might get a bit of a handle on what's involved if they were searching for some info on the same.
This isn't entertainment, it isn't an instructional video, I'm not telling anyone how to do this, I'm not telling anyone else they're doing their job wrong and that my way is better. I just threw a collection of crappy, jerky video clips together for a record of what's involved, and how I bumbled my way through the job and got it done. Oddly, this has become my most watched and most commented-on video. It's comical, really!
Maybe someone can watch it and decide if this is something they want to tackle themselves or hire the job out (to a professional - there certainly seems to be a lot of them here on TH-cam!).
So here's a thought for everyone else: If you've been doing this for years and know better ways to do things, instead of sitting on your butt behind your keyboard pounding out not-so-constructive criticism, take a video of the way YOU do it and post up. As I said, I was looking and didn't find much when I looked. I look at this an opportunity to learn, that's one of the best things about TH-cam. If a guy honestly wants to learn, there's almost no end to what he can find here. Just use your own head and take everything for what it's worth.
Sorry to rant on your comment tdej80!!
@@kellydklassen Not a problem at all and no need to apologize we feel the same! Some of my friends are trying to get me to start a youtube channel. I might just share this video with them. What you are facing on this video is what is stopping me. I have more certifications in welding than most people have teeth, have worked as a mechanic on heavy equipment, do automotive repair at my own shop, change tires on tractors, semi trucks and heavy equipment, I have decent skills on manual machine tool, plumbing, electrical and appliance repair. I could share a lot with many but why do I want to slow down my working to record it just to spend time editing and posting to have keyboard commandos run my video down because I like Chris LeDoux and they don't? The world seems to love buffoons like chuckie2009 not men with real skills! Sorry for my rant, but it is nice to find someone who understands how you feel! Stay cool Brother.
@@kellydklassen After this I had to subscribe, you are spot on man!
@@melaniew77msn
Hey, thick skin brother! You can't be here without it. Some people take this way too seriously! Lol.
By all means, start a channel!! Sounds like you've been around the block, learned a thing or two, and have a lot to offer.
I hold no extraordinary insight with this, many have observed that we have a huge demographic gap in the workforce. We have a lot of older, very skilled, very experienced, and very talented guys on the verge of retirement, and then a gap (that I identify myself in), and then whole pile of eager, young guys starting out with very few of us to generationally pass that baton to them and mentor them. In my industry (construction) I see a crisis of that whole accumulated collective knowledge base being snuffed out in 1 generation.
In my day when I was graduating from high school there was a huge push to pursue higher education and get a degree. Honestly, that was my goal too and I never thought I'd end up in construction, but yet I did. Very few of my peers followed a "industry" or "trades" path. I consider myself lucky to have worked for and learned under masters. Others whom I worked for didn't teach me a thing about construction, but taught me immensely about HOW to work, and how to THINK at work, and how to LEARN. Talk about things that have been lost on a generation!!
So now as a business owner, I take mentoring of my guys very seriously. I make very poor "business" decisions and "waste" a lot more time/money than I should mentoring kids that I'll never get a dime back out of because I'm passionate about this stuff. I'm very good at my job, and I'm always learning. I'm fortunate to have been blessed with people in my life to teach me, and I believe it's my honor and responsibility to pass that along.
I'm not going to pretend for a second that I'm one of the masters in the area of machinery maintenance, nor was it my intention to make this into an instructional video. But maybe someone else can learn from my mistakes, and from some insightful tips from others here in the comments. At the very least I hope it inspires someone else to not be scared to jump into a project that they've never done before. Not blindly or stupidly, but jump in without being afraid to make mistakes and to learn from them.
So long story to say, go for it! Start a channel, share what you've been blessed with, expect to be flamed, and continue on. To be honest, this video aside, most of the comments on my videos have actually been extremely positive. If this is something you've been thinking about starting, I'd like to really encourage you to do it.
Oh, and Chris LeDoux is awesome and highly underrated, so don't let anyone give you crap for that either!
@@kellydklassen I am not as old as my level of experience, I am 38 years old. I started working on everything young. We did not have any money when I was a kid. My Dad fixed everything of ours and stuff for other people to make a few extra dollars. Before I was 10 anything he was doing I was right in there helping. I am lucky my Dad is super smart and working together was how he chose to raise me. In today's modern world people would say my Dad is wrong. I don't feel like he was wrong, he passed his knowledge on. I am a Father and I know now how much he did for me. When ever you are teaching something while you do it that makes things go slower. My Dad is 65 and now sometimes he needs my help. It feels good to be able to pay him back. My Grandpa also taught me a lot not to mention we lived in a poor rural community. So there were a lot of friends and neighbors that were incredibly crafty at trades. You know you were raised right when for help you traded work with people. Where I work overtime comes and goes and being decently skilled at many trades has made me and mine a good living there. I will do any job my boss wants during the week so if the place is open on the weekend he finds ways to get me in. The Lord has blessed me in so many ways and I am grateful and thankful for it! When I was young lazy young was becoming a popular trend so many old timers would teach me just based on the fact that I would work. One friend of my Dad's welded for the gas company. I spent a lot of days earning some knowledge by working for it there.

Use a tripod. The camera movement is sickening/\
Video was OK, but the music is terrible!
it's look's to me you guys did everthing the hard why if you just did 1 side at a time it would have been easier that way you could have just took a chain on the buck and hooked it to the new track chain and put it on the drive sprocket it would have been a lot faster that's just me
Had to stop watching, I got dizzy
Lose the music
bad camera man
Blablablabla
You guys are all old and are making so many rookie mistakes lol... You said you did sprockets last year. Should've done the chains then. You never change one without the other, otherwise you're 100% going to have pre mature wear on your chain bushings. Always cut chain bolt nuts they're scrap anyways also just take one pad off and cut the chain. No need to be wasting time cutting out or beating out the master link pin when you're installing brand new chains with a new master and always clean eating surfaces new or old. Paint and rust creat let small gap which over time wears down and causes your bolts to loosen up and have the potential to snap, stretch or bend if not caught earlier enough.
Can't trust a man who can't even get the terminology right. SMH
