I’m not a man who uses the word beautiful often, and we’re only talking about a Dozer, BUT MAN O MAN with most of the parts put on it that machine is one Beautiful hunk of machinery!!! I’m not talking about the paint. Seeing you take it down to the last nut and bolt and rebuilding it is what is Awsome to me. BIG BIG Congratulations!
Love seeing old equipment brought back to life and restored
45 videos and I've watched every minute of every one of them. I find the job completely fascinating, although I would never have the patients for it even if I had the skills. I know I'll be sad when they're all done.
I can't wait for the excavator, but you are definitely right about projects not getting finished. When you'll get there, we'll get the excavator content and until then we wait with patiently. The caterpillar is pretty interesting as well
I agree, at least he is finishing this first not just having ten unfinished things on the go
I forgot about the excavator. That will be fun to watch next.
Outstanding! Love the work you are doing Matt, your attention to detail and showing us all the Ooops and whoa's as you complete the work is as close to being there as anyone could hope for. Thanks so much for taking the time to bring us along on your journey, this is one of the best Cat rebuild series on the net and your calm, humorous observations as you move forward is a major part of it. Be well.../B
Matt....seriously bud, you truly are a bad a**. To think that just what 45ish videos ago you started a project that frankly looked almost impossible. You literally took it all apart and cleaned, fixed and replaced everything only to actually put it all back together and fired it up to be better than it has been since it was made. Granted, a few hiccups along the way but still.... Props to you sir. Major respect. Hell of a job. HELL of a job. Thanks for taking us along for the ride.
Seriously, you should be very proud of what you’ve accomplished. No easy venture at all. You’re going to have a blast with this thing. Heck yea! 👍👍
Iv put a flat oring between the lever and the seal to help make a dirt n water dam so the seal is protected better! You mentioned if t should fall out it would get caught in the filter- how woul or could it poss get to t he filter
Love the dog, so interested in the hole digging.
The word Hillbilly might be in the name young man, but the work, craftsmanship, and ingenuity says everything but that. You have done a very nice job of reviving the D4. Thanks for the video, stay the course, you are winning.
Is ye be puttin us hillbillys down?
I remember joining your channel when you first spotted the D4 broke down in the woods and you had about 1500 subs. You've come a long way Matt.
Well deserved and you'll soon have that 50k YT plaque. Congrats.
You are so right about finishing projects. I am really looking forward to the excavator, but also feel invested in this and really want to see it completed. What you have done is absolutely amazing! I love this channel!
As an observer, I've rarely commented, but as this series windsup, I must say that the "ride" has been good therapy for me. Your patience over matters large and smart have been remarkable and a constant lesson for me. I'm in awe of your style. This video series of rebuilding an old, worn-out tractor has a far deeper impact than merely another "how-to" on YT. Thank you for sharing your experience with us.
OMG MATT! That is a good idea, get a clapped out lathe and rebuild it. Or just buy anything and rebuild it, I don't care about tractors and I am loving this series.
My favorite part of this video was when you were digging out the arms of your dozer blade and your apprentice went from being curious to playful (by chasing the dirt you shifted with the spade) to determined - I swear he was trying to help you dig!
Thank you Matt for comprehensive filming of your journey in rebuilding the Caterpillar D4. It was of special interest to me as my father who served in WW2 in the Pacific in an airforce construction squadron returned to New Zealand and purchased a War surplus D4 and went contracting specialising in turning scrub land into farm land. Sadly he passed away in 1958 at the young age of 39 when I was only 3 years old. Once again thank you very much for taking us on this journey with you
This has been a great series, can't wait to see you using it when it's done.
The keyway slotting with a Dremel might be the greatest thing I ever seen.
Totally Right to finish one project before starting the next. Good job on the D4
You've done a amazing job restoring this tractor. If it was me, I would trim the blade before I cut the front guard.
Did my heart good to see someone use a proper seal driver! 11:25
Okay now I'm hooked I'll have to watch the next episode to see what happens to the blade brush guard issue! Pretty clever editing! Doggo was thinking finally the human is doing something interesting!
Looking so good, i had an uncle who was a mechanic for a logging company when i was little about 60 years ago, i loved going into the shop and looking at all the dozers, and graders.
I realise you may have already solved the blade to pump guard issue, but the bridle arm brackets are also too close to the tracks and will interfere when the blade moves side to side and also when you use the tilt function.
I believe the only solution is to lengthen the side-arms, probably by cutting the trunnion brackets off and welding another 100mm onto the arms.
Another great video.
Yes. Not forgetting that when there isa load against the blade it will flex in the centre and still push back against the guard, even more so when dirt falls over the back of the blade and gets coagulated in the guard plate holes. Definitely needs at least 4" more clearance.
Thank you Matt,
I do enjoy your ways to improvise when the situation arises. Your a smart fellow to think outside the box with the tools on hand. I have many hours on this exact dozer minus the winch. Looking very nice and bet it will give you many hours of service. To steal a quote from IC welds channel. "This is not a video on how to fix it. This is a video on how I'M going to fix it".
Your hard work shows. Boe
Beautiful restoration of a remarkable old Cat. I had a 1949 D4-7U with ROP and a bigger blade in good working condition that I bought for excavation my homesite on acerage years ago. Not nearly as pretty as yours but a great-running dozer after I replacet what appeared to be the original engine clutch. Almost cried when the project was done and I sold it for what I paid for it. Thanks for the fond memory.
Not too shabby for a Hillbilly! Just a word on that shaft you fabricated: If you want some added protection from moisture try spraying the area above the seals with Fluid Film (I treated the entire inside of my Jeep frame is treated with it}. It is the best rust/corrosion preventative there is in my opinion and it's like $12 a can at most auto parts retailers and heck, you may find other areas you might want to treat. Nice work. Matt!
"not a lot of content" - Says the hillbilly with the most well presented, complete and condensed video series of this type on TH-cam! Epic content as always.
This has been a great series. You made it seem like anyone could do this. I can’t wait for the excavator to get started on.
Love seeing old equipment brought back to life and restored, Seriously, you should be very proud of what you’ve accomplished. No easy venture at all. You’re going to have a blast with this thing.

Thanks for the videos Matt, I have enjoyed every one, since the super sketchy day you got the Cat into your workshop
Thank you, for all of your dedication, on this dozer!It is , for me, an education! Really enjoyed all of your hard work! The weather is getting better, looking forward to you, tearing up some dirt!😀👌
Most Excellent! No apologies needed. Love your dog helping, too.
I've enjoyed watching your progress and particularly like that you clean and paint the components. So many TH-camrs never paint their work and it always looks shabby.
I've watched all 45 episodes maybe a couple more to go. Can't wait to see it in action.
Stay on the Cat till its at a point of satisfaction. It will never be 'done' but it can soon reach a point where you transition from restoration and begin maintenance and improvements. Its been a fun project to watch.. and I'll be here watching all the way.
Was just digging today, repairing a busted water line, and my German Shepherd, that looks just like yours was doing the exact same thing with each shovel of dirt!
Very nice. I agree completely on finishing the project before starting the next. Also, folks can just wait. Simply wait for your next project to start. It's not as if it's that hard to so compared with the amount of work you put in to not just the project but making well produced videos. So I'm writing to just say thanks, and keep it up. I really like the lack of hype and drama and the absence of stupid graphics or other nonsense on the video preview page. There's so much of that on YT and it's great to not see it on your videos. Keep up the deliberate, honest, hard, well researched good work. And, thank you.
Well said. 👍
Hey Matt, I want to just to let you know that I have seen this project from its Inception and you are an incredible individual, doing all of this work all by your lonesome with Charlie by your side sometimes, I am proud of you and if you say you are a hillbilly, I believe you are the smartest hillbilly I have ever seen, trust me I have seen a whole bunch of us out here. God bless.
Watched every video of this D4 it is a 100% credit to you
totally agree finish one job at a time ....
Staying true to the Hillbilly aesthetic. Good man.
I would much rather see you finish up the D-4 before starting on the Excavator. I think your loyal subscribers will hang with you. I sure will. Thanks for bringing us along.
Way to go, Matt! Been with you for most of the 45 videos and have enjoyed every bit of your work. Thanks for bringing us along!
I feel like your the kind of man many of us aspire to be!
I have a neighbor who pieced together a mid 80s D4. No pump on the front but the blade still contacted the radiator shell at full tilt/lift (obviously the wrong blade, but it otherwise fit). Just forward of the main trunnion, he cut the blade arms and sectioned in a 3" piece of solid steel, fish-plated it and got his clearance and then some. Worked fine even with the tilt leaned back to max position.
Love the “Hillbilly” in the title comment! Kudos, you’ve done some amazing work on the machine.
You may want to consider recessing the grille guard to the rear of the mounting tabs instead of on the front. This will provide lots of clearance and retain the appearance of the unit.
Thanks for taking us along on the rebuild. Very good video's and lot's of Hillbilly info. Lol. :)
I'll be waiting for the excavator rebuild.
I've been watching this entire series you've made. You are absolutely killing it, my friend.
You are no hillbilly Mat, you are a genius 👏🏼👏🏼👏🏼👏🏼👏🏼
What a journey. Nice job on the restore and thanks for taking us along
I’m so glad to see you back.
You tickle the heck out of me. Your sense of humor hits me right in the funny bone.
I know you are not a professional mechanic, but you are a lot like me when I was younger. Keep up the great videos.
Your Dozer seems to be a lot easier to move in and out of your Barn, You earned it. Nice to see it coming back together. Always a good watch.
Another day tomorrow my dad always said, I am enjoying watching you sort problems out. Brilliant content.
Congrats, Matt. You have that ole rusted hulk you found in the woods looking and running like it just rolled off the showroom floor! Excellent series.
Thank you for the journey to see you revive your dozer. Looking forward to your concluding videos on the dozer.
Being as I'm a welder I could have fun with that blade. For you, don't cut the pump cover. Cut the bracing on the blade where it's touching, an inch or more so you have room to get the blade all the way up and angled. Then add a couple more on each side where you have room, you could also add a couple more horizontal if your worried about strength. I wouldn't be. Damn nice cat, wish it was mine. Keep smilin. Nothin wrong with Hillbilly.
Hey man, love your videos so much! The double seal is meant for one to stop the oil from coming out, and the top one upside down to stop the water from coming in. My drill heads all have this double seal style above and below the chain case. For the tilt cylinder, it looks like you could put it on the other side to manage the hoses better. You are a really fun worker to watch, reminds me of me :)
I am so upset with myself for not thinking of switching the tilt cylinder to the other side.
I would cut the ribs of the blade back. To make up for the loss of strength I would fabricate additional ribs out of 3/8" thick steel (using plasma cutter) and add them to the remaining portions of the factory rig\bs. Great work. Kind Regards, Craig
There is another hilbilly like character that says: "Git 'er done!" a lot. You are right on track, finish this one, then move to the next!!
It might pay to extend the arms somehow. There is a chance you’ll flex the blade and it’ll eventually hit the brush guard. Then it’s done and out of the way. Great video mate! Watching all the way from New Zealand!!!
Another Kiwi. Yuss
Matt I’m a machinist where I worked they had a apprentice ship program for the new guys coming to the shop . In the beginning of the program they would make the guys file a 1 inch square block it had to be square and to size with in .005 thousands of an inch If they missed the size they would have to take it down to 7/8 . It gave them a good hands on experience. You showed it can be done even if you don’t have a lathe or a Bridgeport mill. Thanks for sharing your videos.
Don't be sorry. Thanks for another free video sir. U rock😎
Holy Cow dude! It seems totally amazing you were able to fabricate that part.
My favorite
Just compelling the thorniness with how he completes tasks.
Any way you can extend the blade arms to get clearance?? Just a thought !! Looks awesome. Did a great job bud !!!!!! 👍👍👍
That is a really good idea. You only need to go 1/8" or 3/16" to get enough clearence. The only thing that might be a problem is the lift cylender attachment.
Was going to ask that about the ram arms. So I asked chatGPT:
The length of rams on a bulldozer may be adjustable, depending on the specific bulldozer model and manufacturer. Rams, also known as hydraulic cylinders, are essential components of a bulldozer's hydraulic system that are responsible for providing the force needed to move the blade up and down.
Some bulldozer models may have adjustable rams that can be extended or retracted to change the length of the blade stroke. However, not all bulldozers may have this feature, and it is important to consult the manufacturer's specifications or a qualified technician to determine whether this is possible for a particular model.
In general, adjusting the length of the rams on a bulldozer requires specialized equipment and technical knowledge. It is not recommended for inexperienced individuals to attempt this on their own, as it can be dangerous and may cause damage to the bulldozer if not done correctly.
And Bard:
Bulldozer rams are typically not adjustable. However, there are some cases where it may be possible to lengthen a bulldozer ram by adding a sleeve to the end of the ram. This would increase the overall length of the ram and allow it to travel further. It is important to note that this is not a common practice and should only be done by a qualified technician.
@@BrettCooper4702 the commenter said to lengthen the ‘arms’ not the rams.
Lengthening the arms will solve a couple of issues. Notice the bridle brackets are also too close to the front of the tracks and will hit when the blade moves even slightly side to side. Also when Matt uses the tilt function, the brackets and the pump guard will hit. Lengthening the arms by about 100mm will fix any clearance problems, both to the tracks and the pump guard.
Can you put in a1/2 inch half round bushing on the front of that push post?
Great Job! I would do 1 of 2 things to resolve the blade clearance, 1: Cut the brush guard down(The angle looks to be to sharp), or 2: cut the support ridges on the blade by 1/4 to 5/16 of an Inch! But it is your Cat., the bottom line is you do what you think the Best!
What a nice surprise to get your video this morning. I feel so bad that you do not have a helper. The parts are so heavy. I am glad that you have taken the time to fix things and to paint. It has been a huge project but soon it will be done. I am real proud of you for sticking with the project. I know that you are excited to have it done and excited to get to the next project. Thanks for the great video.
Charlie was doing a great job of supervising the digging.
Not enough content in this production?
Man, there is load for guy who likes to fix things till they brake (me) !
A great start to my Saturday morning and looking forward to the next one !!
I'm subscribed to about like 100 channels and for some reason watching you build this Cat is my favorite thing to keep tabs on. Its like some oddly satisfying personal victory over something I don't get it but I wish you would put out more videos. I Hope you continue to restore old equipment that still has life and purpose left in it.
thanks
You put a lot of work into that Caterpillar. It's looking great !!! I hope it does a great Job for you.. All you need now is lights..
Matt, I hope once you get the dozer finished you keep making videos of you clearing your property brother, I’d love to see all of your hard work! At work actually my friend, clearing your property and I can’t wait to see the videos of you bringing the excavator back to life! Just saying it’s always nice watching your channel my friend! No matter what video critics say I think you’re an amazing mechanic and very intelligent brother! Thanks for sharing Matt and Kirk from Louisiana waiting for your next video! You might have to modify more as you go brother! I enjoy every video brother! Take your time my friend! Finish one project and then you’ll have time to concentrate on the next! Thanks my friend and I’m always praying for you and your family! I love your dog too brother, he’s definitely a addition to your videos! 🙏🏻🙏🏻🙏🏻👏🏻👏🏻👏🏻👏🏻✌🏻🤙🏻🤙🏻🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸
In the early’70s I worked doing electrical work in a machine shop. They had tubs full of various sized hammers with mushroomed heads marked Caterpillar. These were used for the assembly of the tractors. This may help answer some of your reassembly questions. 😊Steve
haha
Another awesome video Matt, your so close, nice fix on hydraulic shaft, hope the key ways last you many many moons, exciting seeing the blade on,,,,,,
by all means finish the D4. also the d4 project brought me to this channel. 👌👌
Matt you have done a fabulous job on the rebuild ,I have enjoyed every episode you have put on for us all .
Its looking very smart ,well done my friend
Well it's time then to extend the push arms. There is no common sense alternative unless the pin on the track frame can be moved to the next pair of holes. Excellent bullie 🐂 Matt. Looks gorgeous in the half light. Highly visible which is quite a feather in your cap and Caterpillars.
I would grind off the support, it shouldn’t hurt the structure. Great job, sir.
Your all time lows are our all time highs. Love all the ways youre able to skin a cat......
Anytime you restore/ rebuild something you have no personal history with you will run into the issues you have been having. The attribute that gets the job done is the dogged determination to complete the project. Well Done!:)
For what it is worth, your videos are excellent. Don’t apologize for lack of content. It takes a long time to build a pyramid!
Always good to see a 'seat of the pants' solution work and it ended up with a working pump control fix! The blade geometry will be a real puzzle - hope others have some good suggestions!
Induction hardened chrome bar is what you’ve made the new shaft with it looks like. Good stuff. And yes only a small outer layer is hardened
Ya. Same stuff they use on hydro cylinders. Welds great.
For a Hillbilly, you are a master mechanic!
I agree I would like to see the Cat finished before you start the excavator, I learn a lot watching your video and look forward to them. Thanks
The ribs on the blade are for reinforcement, if you trim them it will weaken the blade. Maybe try moving the pump guard back? You are doing great work, keep it up.
I see what you are saying but I personally don’t think shaving a 1/4” off the backs of the ribs is going to do anything. Gotta remember. This crawler was built back when everything was over built by a lot. These day’s companies are trying to skimp anywhere they can to save a buck. So I prob wouldn’t do it on a 2020 dozer. But on this old girl you could probably shave half the part away and it still wouldn’t bother it 😂
Move the pump/radiator guard to the inside of the mounting tabs. Looks like you would have trim a little off each side of the guard to make it work.. Also it would give a little protection for the radiator by moving closer and closing up the gap at the top. The tilt cylinder is going move the blade in and out also side to side. Keep up the good work, you will enjoy it the end.
Regarding the front guard plate. It looks like you could just flatten that angle out some, relocate the bolt hole at the top and that would give you the clearance. You could put a reverse bend at the top to realign the holes after flattening out the lower bend. I don't know how much clearance you would need. Too much and a good size rock/stone would get trapped and cause some damage. So, maybe just enough to clear when it's tilted so that a small rock getting caught won't do much but cause a dent.
Beautiful restoration. It’s been fun watching
Farmer repairs , ya gotta love it what the hell if it works what's the harm ,I can see Matt with a machine shop in His future He really likes making stuff and I have to admit he's been successful and for someone who lack the experience necessary to take on a Job of this magnitude he's done very well for himself ,the More he does the more he'll learn what works and what don't all in all a damn fine job
That Dozer is so nice I wouldn't be able to get it Dirty,with all the parts you've held in your hands, nice job.
29:10 Charlie is being such a good helper ❤️
My grandfather had a D4 when I was a kid did a heap of work with it on tin mines. Brings back great memories. To get a bit of clearance for the blade you could weld in a couple of inches blocks to the push arms probably wouldn't change the geometry of the lift too much.
Great to see the progress ! Thanks for taking us along :-)
"This is going to be a new low for the channel" You are hilarious!
Hillbilly is just fine! Enjoy watching you work on stuff!
What your doing is great! Doing it all by yourself: very impressive. No need to ever apologize. It’s great your keeping that old iron from the scrap heap! Thank You
Just my contribution: I would cut the ribs on the back of the blade. I would cut them back by about 3/4" or more and then add a couple more ribs to counter the loss of rib strength. Great job on the restoration! You are far more meticulous than I would have been.
Finish it up man and don't apologize for your time you put your heart and soul into your work fine job
I have been waiting for this for some time!! Thank you for taking us for this ride. This is just a suggestion for the future, but maybe you won't need it. The front pump pan is the perfect size to catch all the hydraulic fluid that drips when you are taking lines apart.
29:25 the dogs like, you digging up critters let me in there.
