Hi Frank, The reason why there is a weld bead on the cylinder rod is that the adjuster was leaking before you became the owner. Someone made a feeble attempt to fix the problem by extending the adjuster and then welding a bead on the rod to keep it from going back into the bore. This will temporarily hold the track adjustment until the job is finished or the machine is sold. However it will mess up the bore on the cylinder. You never know what you will find when you buy a used piece of equipment. One time I bought a used dozer and it had broken frame bolts. Someone glued the broken bolt heads back on with silicone to cover up the defect. "Life is like a box of chocolates".
@@Digginok Yep, previous set was run to destruction. Also, regarding turning pins and bushings, it is no longer beneficial to do this on a small dozer. The cost of the labor out weighs the benefit you get from extending the life of the chain. Run the chain you have till it destroys itself then get a new set of sealed and lubricated chain and install it yourself with new bolts. You will get two to three times the life out "SALT" chain plus you get a split master link. Always install new sprockets when replacing the track chain.
@@Digginok Definitely after market. Sometimes you can go a on Ebay and find some decent deals. Your chain looks pretty good. I would say you might get another 400 hours out of it depending on how much sand you run in. Sand and rock are track killers.
Wonderful video Frank! Your repair job was top notch. You shouldn't need to touch that idler assembly again until you have your pins rotated. Great video, we really appreciate it!!!
Frank it’s not your fault that someone has jiggered up the piston surface, what you plan to do will work as long as it’s not to long , a good second yolk is needed as you know, I have seen tracks way worse than yours they should last a good while yet (could be 1000hrs) they are hardly worn in my book and I’ve seen a lot tracks and turned quiet a few also, you are doing all the right things frank I hope it all comes out well for you , when I seen that idle leaning over I knew something was wrong now you showed me what it was, thanks frank for making the effort to show it, that little dozer will last you for years with a bit of t.l.c., TOP JOB Frank you did it, that repair could last for years.
Thanks! I hoping for 500-1000 hours to n them. Not feasible to turn pins and bushings, that cost 750$ per track, new track is 1,100$. I’ll run them till they are too long
You do what you gotta do when you are on a budget...... and HOPE ! 🤞👍 I worked for a guy one time that had three old, old dozers and the only thing keeping them going was a LOT of hard facing rod ! He told me that he went through 5 to 600 pounds of it a year ! Good work for what you have to work with ! 😊 Thanks for sharing and take care. 👍
Frank, back in 1988 I had an ACHD4 loader. When thru all that happy horsecrap with the tracks. Yahoo's will do anything to get something to work like that welding. You'll have to get another IH from a bone yard, or find a shop that can bore it out and sleeve it...if possible. Thanks for posting your hard work!!
Looks like you made lemonade out of that batch of lemons there! That fix should last a good while. I read David Morse's comment about why there would be a weld bead on there and it makes sense. I know I shouldn't be surprised at what some people will do to sell something, but yet I am. But it's great to see it back in action again! Thanks for another excellent video!
Yeah it worked out, the guy I bought it from didn’t do that to it. Had to have been done years ago. I have seen some weird stuff done to them, but that wasn’t even a decent weld!
Thanks for the video. I'm looking forward to more dozer operating and maintenence work, it sounds real sweet pushing. it's nice watching someone else work on this stuff and use a practical approach to use what you got. So much of what I do here is similar It's not worth owning some of the expensive tools, that only get used a few times in a lifetime. if you can build something with what you got that works as good or better. I see the guy commented about buying you an electric grease gun. You'd be smart enough to use it without blowing all the seals out of bearings. I worked on a Cat straight cut header for a guy replacing a drive belt. Every single bearing I had to pull to get the belt over shafts the seals were blown out with over greasing. My guess is the idiots have done that to every sealed bearing on all the machines he owns using those grease guns and being "trigger happy" ! Take care.
A lot of tiny victories in this job Frank... especially when grease didn’t squirt past the tensioner seal! Enjoyed the clever fixes for the piston spacer and wear pads... Hope she holds. #FarmallDozerRidesAgain
Good video my friend very good video took me a couple days to finish it started in Blyth California Second half in Phoenix Arizona And the last part here at home Fontana California 😂 Truck Diver life 😂 keep them coming Friend
i hate to make a plug, and i dont gain anything but telling you something that you may already know, but broken tractor.com still makes and carries most of all the parts that you are eventually going to need. the complete adjuster assembly is even a bit cheaper than you thought. i know we do what we have to do to keep these machines going, i just had to rebuild my d3 undercarriage, my boys and i did all the labor, but still cost a fortune because the rails were too far gone. its easy to see that you have it figured out and can do what you need to do to keep her rolling though! keep up the good work.....
I have been able to repair a damaged cylinder bore on a rare item that was scarred in disassembly. Sounds crazy but jb weld. It is a pain. Honed down damage, added small layer of jb weld, used a mild cylinder hone or oil sanded with fine paper. Takes a while but cost a few bucks and time. No leak so far. Maybe delay the inevitable replacement
Yep that’s the way frank ,get the most out of them,in the meantime look around for a track adjuster spacer rod and yolk and maybe sprockets that depends on wear though so when it comes time to replace the track chains you have the rest of the gear you will need for reassembly,
Ive got a td7 that did this about a week ago, gonna try start on it soon, trouble is its gonna be too easy, its at my sons place, all outside work, be alot improvising done
You already have aftermarket rollers on there, the factory ones were solid in the middle and yours I noticed have the hollow spot between each rail which is what my replacement roller look like. I got mine from a guy in Texas. When you decide to do it I would love to see a video of it to see if you did it different.
all the years i worked as a welder in the logging bush camp, and when that bore got messed up i would have the woods garage back in town bore out a new shaft and bore it out for the piston, cut the old one off and weld the new one on when it came up on the daly road runner truck, even though it was a huge company i worked for, they didnt buy new parts if we could make them
Hi Frank I hope by the time you have 400hrs on that dozer and Finished them tracks off you will be still fit and strong enough to wrestle the new ones on 😂 enjoyed vid thanks 👍
Frank, I saw what happened to your track adjuster on a video Brian Vanduyn did last spring. Someone had problems getting it to hold the track tight, so they welded a brace on it right in that area to jerry-rig some bolts to hold it open farther. Maybe, someone welded a piece across there to keep the adjuster from going back in any more, then had to weld that back up after the dozer knocked it off after 10 minutes ;)
Looks about like when I did my highlift. Think just pop a seal in it and be working but end up fixing a dozen more things and still feel like you could had done more. In my case lots more. No telling the history behind the past so called repairs but it's fun to try and analyze it. Makes for good conversation over a couple cold ones or a cup of coffee. Lol
frank, I had a tensioner on my case 650 h that was cracked at the junction with the fork and was leaking. I cut it off and welded it back and it still leaked. However, your welding skills are better than mine so that might work for ya
Oh hell I forgot one other thing Frank the import rollers sometimes do not have seals and you have to modify them to be able to Grease them what I’ve had to do to make them take grease is to cut a groove in the retaining washer at the end of the shaft you will have to pack the center housing with grease first otherwise it will take you a week to get enough grease in it to fill it Good luck buddy the cheap roller seem to be OK as long as they have grease you know like a lot of things
I just rebuilt my track adjuster drove about 10 feet and heard a metal pop sound. sounded like a track bushing or sprocket slipped then the tensioner seal broke again lol. what you think that could be maybe my bushings are so worn that it binds up seemed like that grease seal can only take so much force
Must have been some time back. You were in a t shirt. The tools will be all back in their proper place because it looked like you had every single one out and then some! #dozerman
Looks like the tube bore is a sleave. And some one welded a bead on rod to wedge it to the sleave to remove it. You have to have the sleave turned out of the barrel and install new sleave. And replace the piston and rod..
Nice job..I plan to reseal my tensioner and rebuild blade lift cylinders ..by chance do you have the part numbers for the seal kits..Thanks for the videos .
Do you think some one just tried to put a bush fix on that idler arm? Looks like to me they pulled it out until the track was tight and then put a weld on it to keep it from sliding back in. It almost looked like they tried to weld it on the sleeve itself, I noticed a little slight difference on the end of it when you held it up to the light. Oh well for what ever reason it was you made it work. Great job again!
A TD-15 was my first dozer to operate. Your right about driving a pin on one. It had me hating myself for convincing the boss that we could swap the chain and sprocket out.
I wonder if they didn't put the weld on there to hold the track tight for a cheap repair. The weld was'nt tall enough and it worked it's way into the cylinder end under the pressure. Just a guess without being there to see it.
Looking at the end of the cylinder, it could already have a sleeve in it. The damage to the end of the cylinder could have been where they welded the piston to the cylinder flange.
the name of the game in a big company, was do what you could to get it back working yesterday, worry about fixing it right on shut downs, were were not to worry abut what other parts may need to be replaced later, time is big money
@@Digginok i dont think they forgot to go back and fix it right, more like they did what they could to get it to work, then sold it off, many things are done as well to just get it going to sell it off
@@Digginok i cant agree, as i had said, i worked in a big company logging camp, and i have welded up many to get it back to work, until parts could be shipped up 500 miles from the town shop, thats why i said, when a unit gose down they want it back working yesterday, you do what you have to do to get it going, and worry about fixing t right on a shut down, or until it fails and the parts are sitting in the camp shop, no i dodnt take your coment as any sarcasum, as i thought if your into running a busniess with heavy eqipment, farming eqipment, you would know that you do what you have to to get it back to work, and worry about fixing it right when parts are in hand, time is money..
Well I’d have to say they are better ways than destroying a track tensioner to get it back up and running, that is expensive. More so than making a common sense repair, I have watched my dad take a piece of pipe, cut it to the length needed and split it and wrap it over a track tensioner to get back up and running, and when we had time the pipe was removed and no damage was done to the rod or barrel. I’m sure things are done for various reasons, and I probably shouldn’t try to suppose the intention or the person who made the weld. It could be that the repair was made so the machine could be sold as a working machine, or the other reason you mentioned before. We will most likely never know. I meant you no disrespect as I’m sure when you are in extreme conditions you do what ya gotta do.
Dry ice or a CO2 fire extinguisher will work too. Also I didn't believe this until I saw it but on very small parts turn a can of aerosol keyboard duster upside down and spray. The propellant will super cool things.
@@Digginok Thanks will give them a call. Keep the how to's on the dozer coming, they are helpful. I have a 125C which is the loader version of the TD8C. Doesn't look like a lot of difference between the C's and E's.
I also have a TD8E. My top roller is frozen. It looks like the bracket is welded on. Do you know if there is a press that will fit behind there or do I need to cut it off to press it out?
Put a jack between the roller frame and the underside of the track chain and lift the weight off the top roller. Then remove the bolts on the front of the roller. Under there is a round plate that holds the roller onto the shaft. Remove that and you should be able to slide the roller off the shaft. It might take some doing since your roller is seized. Once you get it off, look at the shaft to see how damaged it is. If it has a heavy groove cut in it then it will need replacing. To do that you need to unbolt the support from the roller frame and take it to someone that can press the shaft out of the support bracket. If the shaft is undamaged you can either put a new roller and seal on or try to fix the old roller with new bearings and put a new seal on the inboard side of the roller. It must be able to hold oil in the reservoir. Clean around the base of the support bracket and verify that it is or is not welded to the track frame. There should be two big bolts down there holding it to the track frame. If it is welded on then someone broke the bolts off so then you would have to cut the welds loose and remove it that way. This bracket only needs removal if the roller shaft is toast. Good luck!
Frank, My guess would be that the previous owner couldn't get the track to stay adjusted. they must have pumped it full of grease then welded the shaft to the cylinder. after years of running it that way the weld broke and the rod slid back into the cylinder.
And now you know the 2 reasons why it was for sale in the first place. One, it is an International product and two, it was broke down, as an International product is pretty much expected to stay. Do your best to put a bandaid on it and dump it for a real piece of equipment, Caterpillar or Case..........
Frank, I have a shop Manual for a TD7, and some roller seals, and some bolts for the blade cutter bar, all new, (if I can find them, you can have them). How can we communicate?
Email me cunningham2442@gmail.com. And thanks! I have a shop manual, and I’m not sure if the 7 and 8 use the same undercarriage, will try to figure that out.
I realize the job is done now. But what about boring the adjuster out to the minimum you’d need to to get it clean. And then have it sleeved? Punch the. Ew sleeve in with some bearing retaining compound. Done deal
That's true. A friend of mine had a lot of used equipment. It kept me busy for almost 20 years. One of the best machines he bought was an old AC 715 C backhoe. Just a simple nice little machine. The biggest breakdown was an injection pump. Not bad for an old machine! Love watching the Vids!

Nice thinking on spacing that cylinder out Frank. I guess we are both learning more about that dozer as you go.
Yes sir, spacing the fork would have worked I bet. I wish it could talk, probably has some cool stories to tell.
@@Digginok It might tell us things we didn't want to know lol
Frank, I saw what happened to your track adjuster on a video Brian Vanduyn did last spring.

Most likely was the case
That looks like a sleeve in the track tightener tube.
A machine shop could clean the bore out and put a new sleeve into the bore for the piston
Pretty sure it’s not sleeved, would be nice if it was.
@@Digginok ok when I saw the opening there was a lip just inside the opening.
Nice work enjoying all the repair videos you share
There is a groove for a seal at the end of it.
Hi surgeon
They say machines make life easier ( well ) until they breakdown then life gets just a little more frustrating?
A TD-15 was my first dozer to operate. Your right about driving a pin on one. It had me hating myself for convincing the boss that we could swap the chain and sprocket out.
We would put the pin on the sprocket I would hold the drift and my dad would swing the hammer. Lucky for me he had a good aim!
I wonder if they didn't put the weld on there to hold the track tight for a cheap repair. The weld was'nt tall enough and it worked it's way into the cylinder end under the pressure. Just a guess without being there to see it.
That’s most likely what they did
Nice repair. What's next?
Hopefully nothing, I could use a small break! Lol thanks for watching.
Other side.🙂
At $800 for the adjuster might be worth checking with a machine shop to see if they could bore and sleeve that torn up one.
Looking at the end of the cylinder, it could already have a sleeve in it. The damage to the end of the cylinder could have been where they welded the piston to the cylinder flange.
Stiff nylon seals sometimes go on for me better if I use hot or close to boiling water.....yup.
True
Sure sounds good
Thanks
Possibly rebore the cylinder to a larger size then go with an oversize piston and rod?
jeff ledlow I think a salvage part would be the cheapest route, for now it’s working just fine though. Thanks for the suggestion though.

A TD7 has the same size track adjuster on them.
Do you have a how to on the upper roller
No not yet.
When ever I do the track pin I put it in the freezer for a few days The steel shrinks and the pin goes in a lot easier .
Good tip thanks!
My father used to do the same thing.
Dry ice or a CO2 fire extinguisher will work too. Also I didn't believe this until I saw it but on very small parts turn a can of aerosol keyboard duster upside down and spray. The propellant will super cool things.
Where are you sourcing those top rollers from? I need some and that sounds like a good price.
Under carriage specialists inc. in OKC
@@Digginok Thanks will give them a call. Keep the how to's on the dozer coming, they are helpful. I have a 125C which is the loader version of the TD8C. Doesn't look like a lot of difference between the C's and E's.
I also have a TD8E. My top roller is frozen. It looks like the bracket is welded on. Do you know if there is a press that will fit behind there or do I need to cut it off to press it out?
I’ll have to look in the manual, not sure.
They are definitely an awesome dozer.
Put a jack between the roller frame and the underside of the track chain and lift the weight off the top roller. Then remove the bolts on the front of the roller. Under there is a round plate that holds the roller onto the shaft. Remove that and you should be able to slide the roller off the shaft. It might take some doing since your roller is seized. Once you get it off, look at the shaft to see how damaged it is. If it has a heavy groove cut in it then it will need replacing. To do that you need to unbolt the support from the roller frame and take it to someone that can press the shaft out of the support bracket. If the shaft is undamaged you can either put a new roller and seal on or try to fix the old roller with new bearings and put a new seal on the inboard side of the roller. It must be able to hold oil in the reservoir. Clean around the base of the support bracket and verify that it is or is not welded to the track frame. There should be two big bolts down there holding it to the track frame. If it is welded on then someone broke the bolts off so then you would have to cut the welds loose and remove it that way. This bracket only needs removal if the roller shaft is toast. Good luck!
Looks like that adjuster bar has a bend in it.
It’s pretty straight, I had it on the lathe. The piece I welded on is a bit out of center but it should be fine.
I would try an old hydraulic cylinder, it is the same concept, modify an old hydraulic cylinder to do the same thing.
I think so too!
Frank, My guess would be that the previous owner couldn't get the track to stay adjusted. they must have pumped it full of grease then welded the shaft to the cylinder. after years of running it that way the weld broke and the rod slid back into the cylinder.
That’s probably right on. The rod was not that far out when I bought it so I think it was on a previous set of chains.
And now you know the 2 reasons why it was for sale in the first place. One, it is an International product and two, it was broke down, as an International product is pretty much expected to stay. Do your best to put a bandaid on it and dump it for a real piece of equipment, Caterpillar or Case..........
Lol
Frank, I have a shop Manual for a TD7, and some roller seals, and some bolts for the blade cutter bar, all new, (if I can find them, you can have them). How can we communicate?
Email me cunningham2442@gmail.com. And thanks! I have a shop manual, and I’m not sure if the 7 and 8 use the same undercarriage, will try to figure that out.
what should be a simple fix almost never is
Boy ain’t that the truth!
Buy a dozer it will be fun, kind of like buying a boat. Hurry up and fix.
At least a dozer can make some money? That’s the plan anyway.
@@Digginok I like that tractor, it has a lot of life left.
👍🇦🇺👍👍👍👍
Check with Ryan at track hut for parts I'll pm you his number
Thanks!
I realize the job is done now. But what about boring the adjuster out to the minimum you’d need to to get it clean. And then have it sleeved? Punch the. Ew sleeve in with some bearing retaining compound. Done deal
Hillbilly engineering to get it through a job or two then get it sold
No hills around here, but I’m making money with it. Used machines are a gamble, but if you stick it out they eventually pay. Thanks for watching!
That's true. A friend of mine had a lot of used equipment. It kept me busy for almost 20 years. One of the best machines he bought was an old AC 715 C backhoe. Just a simple nice little machine. The biggest breakdown was an injection pump. Not bad for an old machine! Love watching the Vids!
