This is my shop assistant - Aw Geez! - Cracked me up!
My dad is loving this series. As a former Cat mechanic now in his late 70’s, this era of D’s was still quite common in the shop during his apprenticeship. When he retired, the machines were heavily dependent on computer modules which caused the older techs to struggle a bit. That’s when he decided to retire.
None of the new techs had the insight into the machines that your dad had. He could stand alongside one of the dozers and look at it and know every bit and piece going on inside of it. He didn’t need computer programs….his program was his keen instinct. They don’t make them like your dad anymore. And we wonder why all the stuff now is junk.
Well if your dad still misses them I have a D-4 dozer that runs but could use some love, And a new owner.
@@beboboymann3823 Yes, junk... That's why things move SO much faster these days, and the operator is infinitely more comfortable...
These comments are just idiotic. Things weren't better in the old days, far from it. Things may have lasted longer because they couldn't calculate anything accurately so they just overbuilt everything, it had nothing to do with craftsmanship or quality, it was purely lack of knowledge. Oh and the old mechanics knowing every bit of a machine? Of course they knew, by the time you met them they worked on just a few types of machines for their entire life, and the machines were incredibly simple compared to these days. Anyone who did that would have an in depth knowledge of those machines...
Seriously, I get the nostalgics, but be realistic... Things weren't better in the past, that's just what people say when they can't keep up with modern day things anymore.
I designed and built tools for inhouse use, welder for 30 years, and while your tool might not have been pretty it got the job done, so good work Matt
Charlie is ready for his close-up at all times.
To line up your clutch disc, disengage the clutch so the disc is loose, slide on the flywheel fully so the disc goes in the notches and then engage the clutch to put pressure on the disc and remove the flywheel.
After the dozer is done and in working condition, you should grab another older picture of equipment, excavator or loader maybe, and go through it and the same rebuild like this. This series has been awesome!
Can't wait to view the D4 out working...
Know nothing about rebuilding machines spent my whole career in a pharmacy. But that homemade socket is pure gold
That socket is a credit to "Hillbilly" ingenuity, "pretty" don't count having it work is a 100% win....
Great work.
Sending Encouragement....
Also, your confidence level has grown 100%, you can hear it in your voice.
Great job with the transmission.
Shop assistant has perfect timing!!!!!!! lol
Let us know in advance when the huge spring is being changed - I'll make sure to have on my hard hat for that episode ...
LMAO ! And Face Shield !
The spring tension is adjusted with a huge long threaded rod going through it so the tension can theoretically be removed. The question is how rusted on and how rounded off is the nut on it. An 8 foot cheater bar is what I eventually needed. What I don't understand is how all those pieces come off Matt's machine without a lot of sound editing and beeping g.
iio
Fifteen seconds in and I am in tears. Good going Charlie! 😂
I'll have to come back later and finish watching your video. I can't see through the tears of laughter.
Matt, that socket solution is a victory for everyone who cobbled something together to get a job done with what you have. You should be proud of that socket and put it on special display in your shop, that's a conversation piece for the ages!
If you don't have shop/home made tools you are not trying Hard enough !
Nicely done!! It was bugging me so I looked it up. Try spanner nut socket.
FYI when adjusting the clutch. Do not cam it over (lock it) without first tightening the "pinch nuts" or you can damage the adjusting threads on the drive shaft. My father bought a D4 in 1982. I was pretty Green , made a lot of mistakes before an 80 year old farmer taught me a few tricks.
The track tension-er spring isn't too bad. As I recall I knocked a pin out of the track to create the space to remove the assembly off the idler wheel. All I had was a 3/4" socket set, pipe wrench and a post maul, not the best for driving hardened steel.
Also, I thing when you put the spring tool on the steering clutch assembly, you put it on upside down. I think the groves around the holes go towards the springs, to retain them, so the springs don't slip off.
Thanks for posting these videos. They're bringing back memories and I'm learning a few new things too.
Glad I was here to hear the first click of a torque wrench on this. Waiting to see it go back to work again is the best part.
You should feel proud to have gotten back to this point! Looks great and all the little mods you’ve done were definitely a way to get it done! It’s gonna be great. Congratulations!
Good afternoon, you are one smart dude. You remind me of my younger brother, he will tackle anything. Thank you so much for taking the time to video. Steve from N.B Canada
I've learned so much from watching these videos. I know you've saved me tens of thousands of dollars by making me realize I'm not capable of rebuilding old tractors.
Matt - Like you, I am a white collar guy (retired) whose stress relief was wrenching on old cars & motorcycles - a gear head. I have restored old motorcycles and 60's muscle cars. Your coverage of your project is top shelf. I don't know if youtube has awards for excellence in story line (content), photography or direction but your journey on this project deserves an award on all three counts!
Here from snowball engineering, he's just repaired a clutch actuator for one of these and I was interested to see how it worked in the vehicle. Now I know, thank you!
Isn't it the most satisfying feeling, when you spend all that time and make a tool, get to the objective and change the part the tool was made for....and then assemble it all correctly? It's one of hundreds of small battles that need to be won, in order to win the war, that is completing this machine. Good on you dude!
Another way to hold the gears and spacers in place is as you retract the spline shaft follow it with a wooden broom handle that is small enough to fit
That’s a great idea.
When you showed the 36mm socket before any welding, I thought you were going to grind notches in the socket to fit the nut. After seeing your modification, I understand what you meant in your message earlier in the week. Anyway, it worked and no one got hurt so that is a win.
I'm glad to see the assembly work started. A journey of 1000 miles begins with one step.
It has got to feel good putting parts back together ! When ever I weld on something next to a bearing , I cover the bearing & shaft with tape to keep splatter out of the parts . Good JOb !
Love the progress in this episode! Can't beat Charlies timing...Intro and the😁 cue to "clean house"!
Matt Tool presents "The Cobble Wobble Shaft Nut remover". Great Job! It doesn't matter how pretty it is only that it does the job. I do enjoy your channel. Thank you!
Should patent that name. lol
You are doing what I used to do. I worked for U.C.C. (Utility Contracting Company) in Jefferson City Mo. We had, argh 146 pieces of equipment. We had up to D-7 dozers and Caterpillar had everything we needed to repair with. This was years ago though. Thank you for posting (seriously, brings back memories) !!
Something to consider.. More than a few of your viewers are in the Pacific Northwest.. When this is all back together, it would great fun to have an inaugural gathering of viewers to come see her run, and have a little pot luck meal.
A dog, a Cat and self made tools. Best video yet. You will be in the dirt before you know it. Those crusty rollers were supposed to be lubed with transmission gear oil. Nobody does it, so your sealed bearing idea is genius.
I’m in my 70’s. My generation ran those not so sophisticated machines and built marvelous things with them. My generation thinks no one now appreciates the contributions the equipment and men made to building things for this country that still serve us all so well today. You do so much to honor those men, machines, and effort in your journey to ride atop a piece of construction history. You are a fascinating guy taking us on an awesome journey and I am addicted to your channel. I hope, when this is complete, that there will be another piece of equipment from our past that you bring to life. God bless you and guide your hands and your mind in this wonderful restoration.n
thank you
I've restored old cars for 40 years. I'm always looking for cool stuff that's different to explore. Having a Cat in your basement qualifies. Dozens are mysterious to the unfamiliar. How cool to demystify the black magic. Super cool series.
Making your own tools is the most interesting part, especially when they work. Nice job!
You must have felt so satisfied when that clutch was in. Well done
those sparks will mess those bearings up
that was my first thought, should have covered that area, with all that flying sparks.
If it's stupid, but it works, then it's not stupid! That fabri-cobbled spanner socket was so just-barely-not-stupid, it was glorious! Bravo! Good work & clever problem solving.
Great to watch a mechanic doing complex tasks! Gutsy to take the transmission apart. Fascinated by the excellent closeups and procedural video! Well done as always!
Why I like your channel. The Cat dozier rebuilds I've seen mostly concentrate on rebuilding the engine and leave the rest of the mechanical assemblies as great mysteries. You let us look into the rest and I like that.
I’m paying close attention as I have an eye on a old D4 and it runs.
0:15 Love how your assistant, Charlie, gets right to work before you did!
Animals and children!!!
The hone was the best tool for that job. Truly enjoy your videos. It's an adventure!
Kind of amazing how you keep overcoming obstacles and inventing tools.
Your toy has come a long way through persistence and creativity.
Really enjoying your channel and triumphs.
Thanks for sharing.
Good to see the dog polish his gear before the day starts greetings frpom oz
You say ugly jerry-rig socket. I see a thing of beauty. Ingenuity and perseverance, along with a healthy dose of tolerance for imperfection. All things I'm learning from you. Thanks.
Slow and steady! Love the kludge socket - as long as it works! Great job and demonstration of patience. I'm enjoying this rebuild. Thanks and I look forward to more. Cheers!!
The Hillbilly socket = " necessity is the mother of inventions " you got build what you need sometimes.
would it be safe to say " this is the turn point to REBUILDING?"
That's how we used to do it and some of us still do it. If you need it and don't have it, you make it with what you have on hand. People are so wasteful now a days.
I sure hope so
👍 making a special tool, always seems to be a hit or miss the first time and is hardly ever "pretty" as long as it works!
Metrics a trip? Try working on a British car. 😖
@@stevenr8606 'smatter, Whitworth tools confusing?
@@mikeznel6048 Yep !
i know you didnt really want to replace that gear ,but take my word you wont regret doing so, also working on big machinery you will find making your own tools work best and better than a tool you only use once, also torch is your very best friend
I am glad that my brake hone idea worked. Before you remove the old track spring relieve the pressure by cutting the coils with a torch while the spring is still caged on the tractor the replacement looks to be assembled already.
I was going to suggest a reamer but the hone is a better idea, and less expensive! Nice job on that fabricobbled tool!
Fabricobbled. I'm stealing that one! 👍
@@carmudgeon7478 LOL! I stole it too. Can't remember where I heard it years ago.
@@mattthescrapwhisperer I wrote it on the last post too!! Definitely the right word for the job!
@@ruaraidhmcdonald-walker9524 LOL!
I a knob here recommended by Snowball Engineering he repair one part of similar that the you installed in that clutch.
I am a fan of mechanics and I enjoy the video and you Sr got me on board.
If the shaft is hollow with tapped ends, a common way of getting the nut on and off on large equipment is to thread in a connector and run liquid nitrogen through the shaft. The shaft will then shrink as it cools, allowing the nut to be spun off easily. This is common on large equipment that have nuts to large to be practically removed with tools.
Yep. Most everyone got some liquid nitrogen layin aroun somewhere.
@@woodhonky3890
Common enough from a gas or agricultural supply. Can also just use nitrogen gas from a welding supply house, just takes a little longer to cool down as it is not going through a phase change. Suppose you could use a 5 gallon bottle of propane with a high pressure (10psi) regulator, and outside without any open flames or sparks within 25 feet.
If there is a doctor's clinic in town, there is a very good chance they have a 20 liter Dewar flask of liquid nitrogen. Could be you buy some from them,or buy from the supplier when they come to refill the flask.
I'm so glad to see things going back together. And staying back together.
Matt, it’s a pleasure to watch your dedication and skills to accomplish your rebuild, best to you on your project.
Hey Matt, when you went to give Charlie his grand intro...he thought you were photographing him for the November Issue of PETHOUSE....lol...great vid...learning alot...I don't have the time, age, or skill set to rebuild a D4, but I am going to purchase a used one for my property up north and your video series has provided invaluable information for me to consider when purchasing a used one...best part...knowing what I am looking at when I see it and what it does and how it fits together...when I started this series, I knew nothing...I know a ton and can probably sound like I know something to someone who doesn't....amazed at the engineering of this machine, so simple, but timeless...the old adage...keep it simple ...stupid...imagine working on a brand new one...its like my 67 Pontiac, 283...could crawl under the hood and get in their with a cooler of beer and work on it...I look under my truck hood now....not a chance...when I was a teenager in the 70s we all wrenched our own cars...so much for progress...thanks for all of the info in your videos...PS I am glad you replaced that lower gear, I almost couldn't sleep when you didn't at first...thank you...
Sweeeeeeet !! Looking awesome brother. Love that your taking your time and getting it right ! Can't wait for the drive line and brake assembly to be all put back together and painted ! Love the videos Matt.
Excellent bit of fettling, can't wait for the next episode.
Good to see some more work doing on the dozer. You wanna use a couple of sizes of hole saw for the brake pads you're making ? Jack two bits up together and put the guide drill though the seam between. Those adjustments are probably crucial? In the clutch I mean. It should drive really nicely once you are finished. I'm doing a repair on a machine at present where all the bearings and seals collapsed. So , hoping both of us have pleasing success with the refurbish. With tool steel you are supposed to anneal the steel and then retemper it. Your socket should respond just as well as the rest of it, if you find it worthwhile at all. Cr.moly seems to be pretty sweet with welding very often.
Methodical mechanical minds are amazing!
Thanks😂😂
I binge watched all of the episodes over the last two days. You are a courageous and industrious man to take on a project of this magnitude. That thing will run another 50 years when you’re done…
Snowball Engineering got me here😀
Best advice I received on running dozer was to do small adjustments constantly instead of trying to do large adjustments less for the blade. And when back dragging, drop the blade all the way hard, when it hits the ground, stop lowering it and then flick it up ever so slightly.
Well, this one came up in my feed and it looked interesting so.
New sub I am.
I'll have to go back to the beginning of this D4 Cat restoration series and get caught up.
You will succeed. I know because you are like me. We think "outside the box". We can see "Go" vs "No Go". We see options others cringe at because we are not adhering to the original engineering. We make improvements (when we can). We understand physics. It is so awesome to watch your progress (in this project) and know that it will work very well. Remember to pause and walk away for a bit if things don't seem right. Your mind will find the right answer. (I know; Preaching to the choir). Love this build, Matt.
It might be your worst welding but that is the best nut remover EVER!
Hey Matt, Love the project and look forward to your updates. Looking good so far!
That old girl is going to be like new when you’re done! Glad to see it’s not just scrap
Matt, you are going to be sooooo happy you fixed that second gear. From an operating standpoint.
Matt, so cool to see pieces go ON the dozer. Loved your homemade spanner tool.
Another way that you can bore bearing seats from the housing, is to use an adjustable reamer. It has 3 blades and a nut at one end, and if you tighten it, the blades move away from the center increasing the diameter.
I’ve just been watching some of your older videos waiting for an update. Love this series & cannot wait to see this thing in action after all of this hard work
Great video Mr Hillbilly. Really enjoying the series. Your camera angles are spot on and you've got decent audio. A few other TH-camrs could learn a lot from watching these vids. Cheers
I think Charlie wants to be known as shop Foreman not shop Assistant, and what you saw there was his form of protest.
LOL !
Hey, Matt! Thanks for your videos! You'll have this gem running before you know it. You will also be one of the few people (comparatively) that know this machine inside and out.
Your doing great. Learning and improvising as you progress through the rebuild.
Holy smokes! She's starting to come together! Another great vid in the series Matt! Thanks for sharing your journey with us.
Flat out impressive job. Really enjoying it.
Impressive!
i think you did accomplish a lot - considering the condition and what you have to do to get to stuff. keep up the good work.
Awesome, you can see it starting to take shape now!
The tear down was something, the re-assembly is something else, how satisfying it must all be for you, I trust you enjoy the earth moving as much when the job is done . great job, lovin' it Matt thank you for sharing.
your dog should be the opener to all your vids thanks for the laugh
Thank you for sharing your work and life with us, we enjoy the show and pray for you, if you do not mind please rebuilt the old engine, thank you again.
I am enjoying the series. Re: the lock tabs on the bolts. You need to lock the bolt head as well or the bolt will back out of the nut. I use loctite in place of those.
Love the ingenuity and the patience you show. The fact you show failures which become successes make this compelling viewing and something many of us can relate to. This baby has fought you the whole way but you keep on progressing - great stuff!
The number of guys who have removed that nut is probably under 100
And only one guy to use a homemade socket , that was sweet
Really enjoying the project. Good stuff
Love seeing Southern ingenuity being applied in the pacific northwest. Good job from south arkansas
Exceptional accomplishments as you continue to overcome obstacles with that ever more rare commodity “common sense”and planned forethought!!! You deserve major acknowledgment for getting this far, and I’ll eagerly await subsequent chapters.
WELL DONE
It's nice to see it going back together again. Good work!
You are doing a great job and I'm looking forward to seeing this machine as it's coming together nicely, I've got all the confidence that you'll get it done as well as can be expected being that it's a major undertaking, already looking forward to the next episode. Cheers from Jacksonville Florida 🌞
I can only imagine what your IQ is trying to keep all those parts in the proper order is amazing love your videos and look forward to the next one take care 🙂
Really enjoy the show. Thank you for sharing how to do this stuff.
I was expecting a really bad tool, what I got was a socket that worked. Thinking on the fly. 👍
Excellent work of disassembly and reassembly for that worn gear replacement. Amazing that we could see the breaker bar bending with that stubborn nut...but the impact drill made short work of it.
Im never in my life, ever gonna touch something like this, but i love watching this!
Keep up the great work, from Norway :)
I am really enjoying this series-Thank You!
Great video and great progress on getting this machine running again!
Intense Engineering and attention to detail... wow !
Impressive and way cool,
I'm so looking forward to the running of this old beast ! Kudos my friend !
🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸
Looking good bud! Can't wait to see it pushing some dirt!
Nice progress! Fun to see how this thing works.
Good Job! Keep up the great filming and Narration!
That is the funniest drill bit I've ever seen lol. If you take your time though, it'll work just fine. Great idea with the hone.
Brilliant job Mat home made special tools are the most valuable in the box.
