I don't understand how your videos don't have more views. They're great.
Thanks Man me either it's a very frustrating game
nice timing D-Boss! heard the ole squeaky squeaky yesterday on the mini cat and then noticed the top roller hanging off the shaft so i appreciate the tips, gonna stuff a jack in there and get it done.
Awesome good luck remember to slack the track off before you put the jack under there so you can get to the bolt
It costs money to make money! But you'll spend a lot more if forced to replace such items on the job site so KUDOS on this video of not only HOW to get the roller change done but SAFELY get it done. That's great safety information and if only ONE viewer is helped out or tells someone else, then great job! Hey, that track reminded me of an old cheap 'watch band' then came the "Twisto-Flex"! Thank you BOSS! Sonny
Yes little key points could save someone's little digits hopefully it gets to the right person!
Like the repair vids as much as the site work
Awesome good to know
It's the DirtBoss 😎 yeah buddy Back in the yard changing them rollers to roll out on a new site 😁 thought we'd like to see it of course we wanna see it cause it's the DirtBoss 😎 yeah buddy DirtBoss I asked a friend who's a equipment mechanic he told me he said soak it with old oil or diesel and run it eventually the kinks will come out 🤔 I believe the trick there is soaking it with oil Thank U DirtBoss 😎 for the great video
Yeah budd thanks
Enjoy this beautiful weekend!
Mrs Elite was complaining that the vibrator was out of her roller... I’m a thinkin’ that she’d love driving those kinks out of your tracks!
Did it get any better yet?
You do a nice job showing and explaining your repairs... If I ever have to change my first excavator roller this is gonna be my go to vid!!!
😂😂😂 too funny
Appreciate you showing us more plant maintenance Mike , always worth watching .👍👍🇬🇧
Thanks man
Nice work and like you said, it really wasn't bad. The safety tips (aka how to save you hands from being mangled) were excellent. I thought sure you'd grease up that rusty top roller bolt!
I know I said the same thing when I watched it back "Grease the bolt" ! 😆
Really like this type of content Boss, so many don't do maintenance or preventative maintenance.
Thanks
Thanks Dave
Mike, try a a couple gallons of used engine oil dripping onto the track chain from the top, while it is slow turning up in the air...spray some penetrating oil into it also then go run it out as you said.
Yes I use PB blaster and the kinks are out
You make it look so much easier than it is Thanks for sharing Dirt Boss
Thanks Frank
Great you put up a video now people will stop watching mine and come over here 😏🤣🤣 just messing with you buddy
Haha Fake News... I'll be over in a minute !
We made a cradle at work that fits on a forklift so you can put the roller up and not have to hold it while you start the bolts.
Yeah that would work
Mike, nice educational video for those that have never done something like that. I found myself doing something similar last week. I threw a track off of my trackhoe and you might know it was in a rough spot to work on it. Never comes off on a cement pad where you can easily jack it up. It had to be in a ditch with all kinds of trash around me. Just my luck.
Yes that's always when it happens! Hope you made out okay..
@@DIRT-BOSS I did and I tighten the other side too. LOL
Mike I had a Dozier one time at the tracks kink like that and we sprayed them down with diesel fuel and marvel mystery oil and running back and forth and they freed up that may work
Yes I will give that a try
Thanks for showing.
Thanks Terry
Looking good. Lots of nice paperweights!
Exactly
Love these mechanical vids.Worked in trades for years.Hey Boss,just a suggestion.Start using ANTI-SIEZE on your fasteners.Anything subjected to dirty,wet conditions is prone to rust and siezure.LOCTITE makes a good product,brush it on your thereads and bolt shanks.it can save hrs of headaches down the road,and it doesn't wash out over time like an oil or grease will.FYI
I understand about the anti-seize I use it on a lot of stuff but this actually calls for loctite on the bolts because of all the vibration they will come right back out
Don't know where you got the sunny weather from, unless the video is from awhile back but up by Glens Falls NY where I am we have had nothing but rain and more to come...LOL. Good vid.
Yeah I hear you about the rain yeah it was shot a day or so ago The sun was out
@@DIRT-BOSS Lucky you...LOL. How far are you from Glens Falls?
@@kidhenderson8260 40 minutes North Greenbush
@@DIRT-BOSS Cool not far away...take care. Enjoy your vids.
You can also use your grease gun to pull out your kinks I've done it a few times good luck love your videos
Thanks
Nice job mate I also interested to do this types of work 🥰
Nice
Changing rolls as well as other part can be a coure or ez depending on size
Very true
Jeez Mike, Clear That Lot in the morning, Do The Rollers, Cut The Lawn. Maybe when you get finished you could throw an other story on your house and re pave the driveway. Friggin Energizer Bunny🐇 Bet You Sleep Like A baby👶
Lol 🐇
Maybe soaking the tracks pins with ATF.
That would work too
Not bad at all. Try putting some oil on the pins where it's froze up might help loosen them up.
Yes I did for 2 days penetrating PB blaster and hot water pressure washer tracked it around a bunch and i got them freed up
@@DIRT-BOSS That's good news
Hey Mike spray the chain with diesel fuel and run it.
I did that before with diesel fuel doesn't have enough lubricant so I use PB blaster for 2 days and it broke it free
Great explaining how too buddy an with safety advice too got the 88 lookin pretay do you keep the old ones that were still good for a back up dirt boss
Yeah the old ones are in the stockpile but probably will scrap eventually
🔥🔥🔥WOOOO!!! Gettin’ that DIRT BOSS fix 🎉🎉🎉
Thanks bro
Nice work mike, yeah can't even imagine how heavy rollers would be on a d11 or d12 man thanks for sharing
Yeah at that point you need equipment to put those in
@@DIRT-BOSS yea fo sho you're videos Rock
Track on a hard surface& put hard blocking where knks are.. Good video.
Thanks
Would putting some kind of lube like oil or PB blaster or something like that on the hing points help break them free?
@@dustinsnyder6977 Yes that's exactly what I did for 2 days it's all freed up
Sweet can't wait to see the next video
nice repair mike, when you removed those old roller bolts with an impact you should use an impact socket, ive had chrome ones explode. i dont want to sound like a jerk, just looking out for your safety. ive been a school bus mechanic for 32 years. also when installing the rollers you could put medium strength loc-tite on the bolts to ensure not loosening, but being able to remove again. could you soak track with diesel fuel and oil mix maybe.
Yes for sure I agree Thanks for the tips. The only short socket I had so I could reach with the gun was that chrome one I didn't want to use it but I was trying to go easy on it
That’s a nice looking scrap pile you have going on prices are up now!!! Mike how come you don’t use anti seize on the roller bolts????? The job came out awesome 😎 as usual!!!! What about your old engine oils on the pads???? Maybe not a good idea cause dirt will stick to it just something I thought of maybe oil them with the WD for the down months of winter 🥶!!???? See you on site!!!!
Yes I used PB blaster It worked great and I will oil them this winter too.. The bolts if I use anti-seize will back out You can actually need to put loctite on them too much vibration
Get some liquid wrench chain oil. Maybe that will keep the pins lubed up when it sits for a while
Yes I did hot water pressure washer then two days of PB blaster straightened her out
@@DIRT-BOSS great stuff, they make PB in Garfield Hgts OH near me Used oil also helps
Well I’m sure glad you showed this that’s exactly what I do with my rollers when I change them… Bro come on how many people do you think actually do this.. haha , I watched the whole thing, thanks
I thought everybody did that 😁
Great video 👍
Thanks
Pour diesel fuel on the pins and bushings and track it around do it a couple of times and good to go.
Yeah I got her all worked out !
Thanks for the video. Very informative especially with pointing out all the extra safety stuff. I'm dreading coughing up the money for new tracks on my machine. Going to do the dipper stick bushings/seals/collars next weekend. Fun times!
For sure Good Luck !
@@DIRT-BOSS I know right lol. Thanks!
Great video! I’m going to have to re track my Volvo Ecr 88 in the next month or so undercarriage is in pretty bad shape
Thanks man yeah it shouldn't be too bad with the 88 same scenario
@@DIRT-BOSS worst part is going to be paying for it lol. I got to have chains, bolts, sprockets, and all the rollers possibly idlers 😓😓.
Do the old rollers get rebuilt or just scrapped
Scrap pile
Was a mustang skid steer in the back ground? I used to have a 940 strong little machine , but a real pain to work on.
Yes that mustang is a powerhouse I have videos of that thing working in my earlier RUclips days.. Hey guys supposed to come by at this Saturday though
Great vid Boss Man!!!!!
Thanks
Great video as always!!
Thanks buddy
Great video and great info. Mike
Thanks
Surprised you didn’t use never seize in any part of the installation.😎
I don't like to use never seize on those parts that are vibrating a lot
Awesome job Mike
Thanks
Good job . Not sure if it will help but sometimes I poor transmission fluid on things to free them up 🤷♂️ some old me dude told about it years ago
Yes tranny fluid does work I used PB blaster for 2 days and sledgehammer I got her straightened out at least she's scared of me now !
@@DIRT-BOSS 👍 yeah my wife says PB blaster is my Cologne 😂. I guess I stink
Great video Dirt Boss, Love watching. Great content.
Thanks
Is there a core exchange for these rollers? Wondering about cost.
No core
Great video brother, the top rollers are just a little more pain in the a&$ than the bottom ones lol
Thanks bud
Reminded me of the song Rollin' by Limp Bizkit, LOL
Lol love that song
Try spraying some diesel fuel along the chain and then track around and keep spraying diesel fuel on them
Thanks
@@DIRT-BOSS some times you might have to smack them with a sledgehammer but I think if you douse them pretty good and track around it should work
Nice video.
Thanks
Hi, we can replace the 18 under rollers of a komatsu 210 excavator. 9 rollers per side. In 8 hours. 1 man.
If, everything is going normally.
Nice The key phrase is if everything goes right !
👍👍
Thanks
How’s those elbows holding up Mikey?
Elbow s are feeling good I actually was swinging a sledgehammer on those tracks for hours yesterday
Badass
i have kinks in my Link-Belt 135 track...they drive me crazy
I got them out hot water pressure washer then two days of PB blaster watch my story
👍🏻
Thanks
Waste a bottle of wd40 on the track chains then track it around.
I hear you
I always said
If you own equipment better learn how to turn wrenches!
💯
Chrome sockets on an impact driver???? Come on man :-)
Yeah I know That's all I had for a short socket was hoping someone would send me the correct ones! 😂😂😂
& cheaper
Yup
Nice work and like you said, it really wasn't bad. The safety tips (aka how to save you hands from being mangled) were excellent. I thought sure you'd grease up that rusty top roller bolt!
