I’m looking at a 450c next week that will need an undercarriage, so this video was very helpful of what it will take to get squared away. Thanks for taking the time to make it.
i replaced mine 100% everything, I recommend get a good inspection at all the components and dont mix worn rollers on new chains, and definitely replace all the grease adjuster seals. I used 1/2 bolt hole dry chains that were much cheaper than salt chains because mine is a home use only machine that saved me a lot of money. if you need bottom rollers, I highly recommend just jack the machine up on blocks and pull the entire frame and flip it upside down to change them it would be a nightmare otherwise because all the bottom roller threads are exposed, I also recommend a full hardware kit because all the roller bolts are grade 8 fine thread and they are not common at any local hardware store. I ordered my entire undercarriage with all rollers and sprockets and all hardware and it was about 8500 dry chains, 1/2 bolt hole grousers and press fit top rollers. and be sure to put the oil zerk on the rollers to the outside of the rails for easier access if you ever need to add oil.
I replaced my sprockets, bottom rollers, and top rollers last week on my 450G. I like the ITR stuff never had a minute trouble, and any quality issues I've ever had I called them and it's handled immediately
I like the modern aftermarket rollers. Much better to service if they need oil or be checked. So far it’s holding up really well and pushes much better.
Nice! I’ve only helped do this once on a D8. We took the grease zert out of the track adjuster and feed steel rods in to the sprocket to bring the adjuster back to the minimum position.
On your final drive, remove the clutch set screw plug and check to see if the clutch cavity is filling with oil. You might have a leak on the clutch. These are wet clutches so should have some oil in it, but if you have a leak it will fill up the cavity faster than it can return to the transmission. We drill a piece of angle iron to bolt to the top two pinion bolt holes with a lifting hook welded to the top. Makes final drive removal easy. An anaerobic sealant is used to seal the final drive to the clutch case.
@@Paw95 I remember when i replaced the ignition system on my 1949 model B it cost me about 100 bucks and I went through through John Deere get them. I probably could’ve gotten them somewhere else but I wanted to go through John Deere because I trust them if you trust where you are getting the parts, the less headaches you have down the road
@@rudycarlson8245 yes true. I usually go to them for parts and I’ll also use Napa parts and oil filters. I try and take good care of it because they sure are expensive to maintain if you don’t keep up.
I can’t believe the track pin came out so easy. My 86 450c has great tracks and idlers with sharp sprockets which seems odd. I’ve owned it 2 years. I’m tempted to get new sprockets but they say it could where the chains worse. My old man who is a mechanic and fixed many undercarriages says run it until there’s a problem.
One thing I found out is that it’s expensive lol. Yeah all my stuff was just shot all to heck. That new undercarriage is very nice! It’s much quieter and pushes better.
if you get the specs and check the pitch on the chains you can confirm if your close to needing chains, and I would NOT put new sprockets on near outta spec chains it would wear them out very quick, My dealer that sold me my UC told me that info. if its pretty smooth and not jumping let that dog eat. keep the track sag at 5/8 from sprocket to top idler.
I was told that also. But I just got new anyway. It’s hard to find a good machine shop close to do anything like that and I don’t have the time myself since I work a lot.
Thanks you very much for the video👍 I’m trying to do same thing on my 450C, a mechanic told me that all 10 of my lower rollers are worn out and find it hard to believe that all 10 of them are worn out because they’re like 150 bucks apiece. I don’t use this machine to make a living just digging some ponds on my place. I measured my rails and they’re only 50% worn out so I’m gonna leave those on there and the previous owner put new sprockets and idlers on it so I guess I’m gonna have to change all those rollers by the way are you interested in coming to North Texas? Lol!!
Good job thank you for sharing now that it's over with would you have been better off buying a newer Dozer considering your material Time and Labor that you put into this 450c
I don’t know really. Newer dozers in my area are really high. Also people have been complaining about the electronics on the new stuff because it takes a technician to work on them.
Just so you know there is a check ball in the grease of the track tensioner. I have seen like 10 vids of guys loosing that check ball. In 1 vid i could hear that ball bearing fall and hit the track when the grease is released. Nice job!! So the new track pads and old pads are not interchangeable? that sucks.
You said you gave 5k in your John Deere chain rails is that what you ended up ordering is them? My dealer in ft worth told me about truckortrack and they are 1050 each side on the rails. My idler and sprocket are good but I need all 10 of the lower rollers and they are 145 each. Thanks for sharing👍 I’ll be trying all this the week after thanksgiving.
I tried that for a few weeks on Facebook but no one wanted them so I scrapped them. Wasn’t much good on them anyway. The right side had probably 1 inch left of grouser bar left though.
I'm looking at purchasing this model that is for sale locally. Maybe you have some insight for me... between this older JD 450c dozer and a 100hp skid steer with a tooth bucket, what do you think would regrade the slope of a steep rocky hill faster (clay and chert rock)?
Made in South Korea if I remember right. Funny thing is the John Deere parts I’ve ordered in the past was made in China!! John Deere doesn’t make much in country anymore. ITR undercarriage is holding up really well.
@@Paw95 , thanks for the follow up. Yeah, definitely hard to find things made here. As long as it works and lasts, doesn’t really matter where from. Cheers 🍻
@@BigBlockSpence a guy I know when I did a job for him only $80 an hour. That’s really cheap and it was my first job. The rate in my area is like $120 now.
Did you not see that I did put new bolt? Why would I use lock tight? They was already really tight without it when I took them out. Lock tight has its place and it’s definitely not on dozer undercarriage.
I did see you put new bolts on all the parts but didn't see you put new bolts on the sprockets. If I missed that I Apologize but I would still use loctite (blue) and wouldn't relief on rust to keep my bolts tight when I had just spent that much money.
If you can stand some constructive criticism, you should have sped through the boring bolting/unbolting stuff. The video would me much shorter and may have gotten you more viewers. Also, you should get a big-ass breaker bar. Other than that, nice job.
Well then big guys have videos that’s well over an hour. Like Matt on diesel creek. People like him video about everything they do when working on stuff. There is a lot of different factors that make a video be seen. Has to do with thumbnails, how many you put out and the type of video. Thanks for watching.
@@Paw95 yeah but for an instructional tutorial every step is crucial. Plus most people following the algorithm aren't watching a bull dozer undercarriage replacement

Definitely needed replaced. Those Milwaukee 3/4 impacts are amazing. The mechanics have one at work. Great video my friend 👍😎
You got that right! Thanks for watching!!

Thanks!
@@user-tv5dt3nm9y thanks for watching.
Boy! You sure don’t mind taking on big projects solo! Kudos sir!
I hope that’s the last one for a while!!! Haha
Informative, thank you! Great to learn in advance of our 450 needing a refit. Cheers 🍻

That’s some good info to have! Thanks! I’ll remember that when I go digging into that job.
@@Paw95 when replacing the under cage on this dozer did most of the parts come through John Deere?
@@rudycarlson8245 all of them came from John Deere but it was ITR aftermarket.

Love the videos. New subscriber here. I have been trying to find a 450c that nice for my dad.
They cost money to own but it’s really handy to have around!! Thanks for watching
You can have those sprockets reringged and your new rails when needed can have pins and bushings turned
I was told that also. But I just got new anyway. It’s hard to find a good machine shop close to do anything like that and I don’t have the time myself since I work a lot.
😅wel wat a job,but you are the specialist.super nice video,mutch sucses with the dozer Preston. greetz:Peer.🍐🍻
Need to start on more big projects hahaha
😅@@Paw95 wel wat about 1 cartepillar D11?🤣you can do it.👍👍👍
Hell yeah man it looks much better
It works so much better also.
@@Paw95 I seen your short video and definitely much less clunking noises
I’ve got a big Miskito that will break the lose or break the bolts best battery unpacked I have ever used with to wire settings on the gun .
Stuff like that is really great for working on rusted or old equipment for sure!
👍
😊nice job to do.Preston.😅
I’m still wore out from it hahah
Thanks you very much for the video👍 I’m trying to do same thing on my 450C, a mechanic told me that all 10 of my lower rollers are worn out and find it hard to believe that all 10 of them are worn out because they’re like 150 bucks apiece.

Lol!!
Wow Texas is a long drive lol I’ve been there before and as far south as Corpus Christi lol.
great channel I've I jd350 and now know how to change the sprockets I'VE SUBSCIBE ! 👍
Thanks for that! Glad you liked it!
I did

Yeah I still have the check ball. Yeah the new and old stuff use different size bolts unfortunately. Thanks for watching!
you are the first ive seen to not loose the balls lol great work @@Paw95
Great Video, Gives me confidence I can change out my under carriage Thanks again , By chane did you record any of the head gasket you changed?
Yes I did. I have it on the 450c playlist.
Why did you not replace the rolls?
@@Camera1931-p5v rolls? Rollers you mean? Because they didn’t need to be and they was an extra $3,000.
Didn't show us the best bit, getting the track back together!
That was a hard job right there. Probably the hardest part
You said you gave 5k in your John Deere chain rails is that what you ended up ordering is them? My dealer in ft worth told me about truckortrack and they are 1050 each side on the rails.

That's not for the faint hearted!!!
Big job for sure!!
you selling the grousers per chance from your old tracks?
I tried that for a few weeks on Facebook but no one wanted them so I scrapped them. Wasn’t much good on them anyway. The right side had probably 1 inch left of grouser bar left though.
@@Paw95 id be very interested in quite a few of them as i have c channel cut up to replace pads on mine that wore through
@@Paw95 how do i find you on fb?
@@robertlaplante8043 I took everything into the scrap yard back in December after several attempts to sell. I don’t have anything left anymore.

I’d go with the skidsteer if I was you. A dozer is great but you can do so much more with the skidsteer.
@@Paw95 Thank you. That’s what I was feeling.
What was the cost difference between JD and Chineseium?
Made in South Korea if I remember right. Funny thing is the John Deere parts I’ve ordered in the past was made in China!! John Deere doesn’t make much in country anymore. ITR undercarriage is holding up really well.
John Deere was double I think. That’s coming from the John Deere sales rep. He said aftermarket stuff they sell is just as good.
@@Paw95 , thanks for the follow up. Yeah, definitely hard to find things made here. As long as it works and lasts, doesn’t really matter where from. Cheers 🍻
What do you charge /hr to run that dozer?
@@BigBlockSpence a guy I know when I did a job for him only $80 an hour. That’s really cheap and it was my first job. The rate in my area is like $120 now.
Thanks. Good info.
Is your idler wheel bearing no good?
One of the front ones was going out.
You want the best torque when backing bolts out STOP using wobble heads lol I’m a snap on guy other than your choice in tools nice vid 😂
I try to buy the best tools lol. Thanks for watching today.
Can u send the link on where u bought the parts
I have to do the same to my 450c
I don’t really have a link. It came from my nearest John Deere dealership. Do you have any near you?
@@Paw95yes I’ll call them up
your investing 10,000.00 why wouldn't you use new bolts and Loctite them on for the sprockets?
Did you not see that I did put new bolt? Why would I use lock tight? They was already really tight without it when I took them out. Lock tight has its place and it’s definitely not on dozer undercarriage.

Y wouldn't you do the work on this thing either in your garage or atleast close to it instead of out in the field
Because I don’t have a garage. Did it to the closest power pole for lights and tools. Not everyone has a garage
@Paw95 thought I seen a shed in one video
@@rondierckens6618 you probably did and it wasn’t mine though. Will get me something soon.
