Heat up a sewing needle or a really small drill bit and poke it through you get a little blood coming out your release the pressure and it won't throb like that you may not lose your nail ,
Small drill bit works best
We used to use a small piece of wire, heated red-hot with a torch. It melts right through the nail, and doesn't hurt. That bruise is right at the cuticle; he's gonna lose the fingernail.
I always have the wife drill thru the nail, provides immediate relief.
Yup... went to ER 60 years ago and a heated paper clip.slipped right thru the nail and released the blood... and the pain...
You have tripped something in the youtube algorithm. I think your channel is going to take off. Finger gore, crazy wrenching on heavy equipment, good lighting, scaring the dog, excellent stuff. Dog play sequences interspersed are also a big hit with viewers.
Matt, I'm new to the channel and like what your doing. I could be wrong, but I think I hear you justify stripping the engine down to its bones like you think you shouldn't be doing it or someone has said something that you shouldn't do it. It's perfectly fine to strip it down to it's smallest component, it's your personal project and you can do whatever you want. It also means its getting restored right and your learning how it works too, there is nothing wrong with that.. And we get to go on that journey with you as well without getting our hands dirty or hurt our fingers. Because you are the one doing the work, none of us viewer have the right to say anything about anything what you are doing. Keep it up and do whatever you want to do, I'm really interested in seeing what you eventually end up with. I hope your finger is ok.
Matt, my kind of guy, may not know what you are or should be doing yet but keep going as the learning curve will start to flatten out. Just think how easy your next dozer teardown will be.
*- Thank you so much for saying just what you said here.*
*- In the deep future, you will have come to see the pride and sense of self-accomplishment Matt has grown into as he continues to paint each finished part as it gets done.*
*- I am please for him and that you had the good sense early on to encourage him.*
*- Again, thank you.*
Great comment. Yeah, he might not need to, and it would definitely be cheaper and easier than a full teardown. That being said, my first experience wrenching was as a teen, on a barn find, $400 (oddly enough) 1972 240z. My dad and I rolled it into our barn and with his help, me made me take that thing completely apart. Best mechanic lesson I've ever had..... And it let me know that I will never tear one down completely again, unless I HAVE to! 😂
I subbed after the first dozer video. As others have said, the content is great and the quality is even better. I'd prepare for a lot of new subs if you keep this kind of quality to your videos. Don't forget- the best time to clean and paint is when it's in pieces! And don't skimp on gaskets and seals.
Made an effort for o watch the first set of viggies! Since you he engine / transmission rebuild ones were so good!
Great work & Effort!
From Somewhere in SWMO-
Started watching the excavator rebuild. Thankfully the back catalogue is here to fill the time in between videos.
As a fan of old tractors , I’m finding your series interesting . It’s amazing how heavily built everything is
Thanks for the video. Ive restored several dozers, the latest being a full resto of a john deere 440. Youre doing good work on the disassembly. If I may give good advice, spend the money and replace any parts that are questionable or suspect. Dont half measure anything and take your time putting it back together. Take good photos and notes. Dont pay attention to the nay sayers. They can talk about how they would do this and that, buy you can bet they dont have the balls and perseverance to attempt to restore a machine like that.
Those old Cat engines were built tough with cro magnon engineering/ reliability. If you do it right, that dozer will almost outlast a brand new cat bought today.
Best of luck,
Find an old cat knuckle buster , and get input there other guys that overhauled theirs on line too.Locwashers were used before loctite chase all bolt holes with bottom taps and cheap spray lube wear goggles !! Spring is for clutch handle to return to disengagement by itself.Do all clutch service now,other way is much worse to do between your legs.Drill and use ease out kit on broken studs , sometimes a little heat -dull gray and a shot of water heat again and should back out..Or tap with small hammer and soak with a rust buster and repeat for a day or two let sit over night.
I just wanted to say: viewer count is not indicative of quality when it comes to content. So just keep up the interesting vids, and eventually the public will catch on.
Haha, thanks for the comment! I'm really just joking about the viewers...I'm not here to be famous, just to keep a record of my projects. Coming back a year or two later and watching a video of yourself doing something is highly entertaining: you feel nostalgia, you laugh at yourself, and you cringe at your old bad jokes and ideas.
Small channels often deliver much better content, because they can focus deeply on something. Keep it up :)
Absolutely true, I just found this channel and subscribed 1 minute into part 1 of the Bulldozer videos. 😁😎
Click on the like button and the YT algorithm ,the really important thing, will start recommending the channel. There are several billion vids on YT and there are even similar vids but because of low 'like count' the algorithm pushes them into dark corners,only to be discovered by accident in the distant future.
You should've drilled the fingernail right away. It relieves all the pressure which is causing the pain and if done soon enough, could prevent from loosing the nail.
Great content. Thank you for sharing your project.
Thanks for putting as much effort into your vids as you do on the restoration. I know it adds a lot more time to the project but your content will be invaluable to those of us attempting a similar restoration.
btw don't know a caterpillar restorer who doesn't mangle a finger or two in the process - welcome to the fraternity!
THERE IS NO WAY - NO WAY - you could ever start that engine as it was without causing total destruction and catastrophic failure! This is good that you're finding all the issues as you remove parts.
Good bless your channel for showing people "how things were made 'back when,'"
Quality content, no adds. You sir are very humble. Not a know it all. Very enjoyable.
You're going to have a nice reliable dozer when you are finished. It reminds me of a a project I did many years ago when I thought I had bit off more than I could chew. An old guy could see my frustration, smiled and said," It's like eating an elephant. One bite at a time."
A red hot needle works great for a nail full of blood. It just burns down through the nail and releases the pressure.
Take a very small, clean drill bit and using just your fingers, drill a hole in your finger nail. You can't believe the pressure that builds up. Trust me, it will feel a whole lot better. I'm a retired machinist and had to do it several times. Enjoying your project. keep up the good work.
I think you’re right up there with Diesel Creek and Camarata, maybe even better in some respects. Good lighting and play by play descriptions. People will discover your channel as I have. Myself I’m not interested in ducks.
Really like your taking on the rehabilitation of the D4. Obviously, you, as well as more than a few of your subscribers, have injured fingers,or thumbs, that can slam the brakes on. Ive found my go-to remedy for those types of injuries, is a aluminum expanded metal splint, found in some higher end 1st aid kits...or Amazon. Dress the cleaned finger, then cut a section of metal half an inch longer than your finger, and wide enough to encircle the finger one and a half times. Tape it securely around the finger, gently fold the end in ,covering the end, and go back to work. You can keep working and not worry about hitting it and launching you into low orbit. You can shower with it on, depending on whether its a crush or laceration....take it off to inspect and replace it as it is a custom fit. Just sayin'!
.White shirt ... oil grease and hydraulic fluid , plus 40 years of dirt. Enjoying the series Thanks
it's funny how you talk to the camera exactly like how I talk to myself or the dogs- like they would answer
I love watching the grease and oil art developing on the concrete floor.
I watched the next video first so I was anxiously waiting for the finger injury! 😬 Is it going to be the fuel tower? The mallet? The chisel? The suspense! Hope it’s healing up. 🩹
I am a viewer too, and I have put in my time working on old machinery. Lived for 26 years in the PNW, so know the rain and all as well. Don't give up, you will get 'er running again.
Your cat showed up on my feed so I started watching. As soon as I get caught up with the cat I'm curious if your car was on your channel. Your cat seems in good shape other than sitting in the woods for years. I like the idea of this taking you months to get it to run. Some youtubers get them up and running quick and then you never see the project again. I like watching old iron saved. And for the love of god PAINT IT!!! No such thing as character in old faded paint!!!!
I have the same Cat . My great grandfather bought it new in 1951
Heavy equipment is like airplanes , They eat money ! Very nice project .
I agree with the previous viewer, you are doing something that most of us can only envy, your skill and and dedication, to bring this Cat back to life.
Great project, man... I'm thoroughly enjoying watching it.
Just discovered your channel today, I must say that I love it! I watch Diesel Creek, Salvage Workshop you are right there as entertaining. Love your videos and don't give up, I am looking forward one day when you crank it up!
I believe a large parts washer tank is in order, you’ll never have a better chance to find small cracks then while it is broken down.
Next time you smash your finger like that, get a small drill bit and drill through the nail BY HAND. The second you go through the fingernail and the blood comes out, your finger will feel better. Instant relief. I’ve done it dozens of times. Keep doing what you are doing.
Keep up the good videos. Don’t give up. Going to be interesting to see what you find.
I think that CAT was submerged at one point. But keep going. I'm loving this project.
Good job.Nice to see old machines but back to work.
Just found this channel. Love the content and the production. One thing to think about. If the engine is sleeved, you may want to pop the sleeves to clean the water jacket cavities around the sleeves. If the cooling system is that mucked up you will want to clean those areas out, right where the heat is generated.
I would go further and boil the block and head.
Thanks for the addiction.
It's fascinating watching you struggle to figure out how to get it apart, figure out what's salvageable and what needs to be replaced.
You've an excellent ability to track down sources for parts and knowledge as well.
Found your first video on the dozer this morning and subbed you straight away mate, Watching from Queensland Australia. You are in my opinion doing a great job. Thanks for the effort you put into the videos. Cheers, Rob.
I found a couple of your recent vids now I'm going back and watching them all in order
Drill your finger nail to relieve the pressure, will make it feel better .
It will squirt blood and pus.
Hello from Siesta Key Florida
small drillbit and punch a tiny 1/32 or 1/64 hole through the back of that nail to relieve the pressure.. I realize this is 16 months too late, but future reference.
Tremendous video, love your mechanical work and video editing. I could never tackle a project as big as this, but I'm learning so much with your project. What has me stumped is, "how on earth do you know how it all goes back together?" All respect to you. (John in Sydney, Australia)👍
Thanks John!
At approx 3:23 Matt answers that question. He plays back his recording(s); the unedited disassembly recording(s).
They show/remind him how to reassemble anything he can't remember.
Thanks Dan, I missed that part.👍
@@SydneyTowne // Sure thing.
I found it much easier to remove the equalizer spring under the engine. Then the machine can stay level. Much easier to install the engine too.
A set of impact wobble sockets will help a lot using the impact driver!
Keep it up Matt. You’re doing awesome man. We are watching these videos. Pretty interesting! 👍🏻
Man you got guts tackling a job like this. Keep the faith
Love it.
Every project starts having the guts to begin.
Good on you to dare.
Painful, these nails squeese. Next time (there will be) glow a thich needle over a gas flame, and carefully melt a hole through the nail. If its fresh, if not, dont bother. The blood will gush out. Instant relief. Great uploads, nice channel, thanks!
You are brave, hope you can put it working together, good luck
Great channel and content. Keep up the good work. Oh, and the fingernail, get a needle and heat the end to red hot and then melt through the nail to relieve pressure under the nail. It will bleed a little but with the reduction in pressure under the nail, it should feel better.
Matt you now have 9 viewers. Love watching your project.
Anyone that has ever worked in a shop knows the pain that comes from a smashed finger nail. You can take a straight pin and heat the head up with a blow torch and push it through the nail. It will certainly relieve the throbbing pain... Thumbs Up!
Enjoying your project.
To make things a little easier sweep the floor every evening before you quit for the day. Clean floor makes finding parts you drop easier and sucks less to work in a clean environment.
Matt, love the videos. Beautifu workshop with the new lights. Keep up the good work.
Good job. Thanks for doing what you do.
A fascinating project. Thanks for sharing. Subscribed.
About the finger nail. Try drilling a small hole in the center of the black area that will take away the thumbing and you might save the nail.
That's a real owieee! Hurts up the entire arm I bet... It's been a long time since I smashed a finger that bad. Maybe doctors have some other remedy for the pain by now. But my doctor used to drill a small hole in the nail to relieve the pressure - thus a good share of the pain. That blood would just shoot out of there.
Nice work - it's past this old man's bedtime. Maybe just one more video...
I always love seeing these comments on this video, knowing what happens in the next video 🤣
An old timer bush remedy for a black nail injury like that is to heat a needle up cherry red and use it to slowly bore just through the thickness of the fingernail to relieve pressure behind it!
I've lost fingernails before...as I recall, the painful part is before the nail comes off. After that, it's really crucial to keep the fingertip cleaned & bandaged.
I used to be a Cat mech & training instructor way-back. Never worked on a D4 this old. It grieves me to see HB using standard extension bars & sockets with an impact wrench, as well as using a hammer--even a soft one--on wrenches. I don't think that parts catalogs are available for these machines anymore. When I was training instructor all those books were available only on microfiche. I would try to see if shop manuals can be found online on the Cat website. I enjoy watching you solve tear-down problems.
I’m a new subscriber too, I like this guy. I used to live in Portland, I wander just exactly where he’s located.
Too late now but when I smash a finger nail like you did I drill a hole in the nail to relieve the pressure, A paper clip heated red hot also works. After you heat the paper clip red hot very carefully tough the nail just enough to melt the nail and the blood will cool the paper clip. Not for the faint of heart. Good luck. you are doing a fine job.
Cats have 9 lives. You're probably bringing it back for number 3 or 4. Good job. Enjoying it.
Because of this video I ordered a book !!!👍😊
Thanks for the videos! Very interesting content.
it will hurt like hell, but relieve the pressure behind the nail with a tiny drill bit. After pressure is off, finger will feel much better. Have been a cat mechanic for years and have many smashed fingers and nail drains. good luck
Hi, I just came across you series of video's on this dozer. Have been working my way through them. Watched them out of order though. So I have been waiting to see how you smashed the finger.
Great videos Matt
New subscriber. Excellent video. My dad purchased an almost identical Cat D4 up in Alberta Canada years ago. It too was a bush dozer with the same winch, roll cage and blade. I had a pup motor.
We never got around to working on it like you are. Enjoying your project a lot.
Thanks!
Good work man i love those old cat machines i own an old cat 920 wheel loader keep that old girl alive 👍👍
Your ratio of views to subscribers looks pretty good. Much better than mine! Good content; keep em coming!
put all the nuts and bolts in plastic bags , mark where they came from , so you don't have some left over when you put it back together, good project !
If you take a paerclip straighten in out 1/2 way heat the point witha lighter until it glows and then brand your way through the nail into the blood it will releive the pressure and pain. My peditrition did this for me when I was a 10 yr old boy.
Good job
Heat a sowing needle red hot and burn a hole in the nail to drain the blood out. It’ll feel so much better. Do not push too hard or you’ll go into your finger and that hurts. You can also use a small drill bit.
Water cooled Generator! Nice!
Subbed after first video. Great content.
12 in blocking under rear sprockets, level out engine block, remove spring. much easier
block trans
It looks like the dozer may have been sunk. That would explain the rust throughout any place water could have gotten into it. A possible explanation.
New to your chanel & I can feel your "what have I got myself into" here. You know, when your done with this, project, you are going to be a changed man. Hoping you see it through to the end & set up a Patreon account if you haven't yet, your going to need it if your wife sees how much green you will end up plowing into this Cat, trust me!
Also, forget the poking a hot needle into your nail. Chuck up the smallest drill bit you have in your drill. Mount it in your vise & turn it on w/the anti fatig button. Carefully move your nail into the bit while its running till it goes through. Your pain will instantly quit and the nail will not come off unless it's too late.
^ What he said ^
Think you from Cheboygan MI
Next time you get a smashed finger with a nail bed doing what yours did, get a small drill, like #52 or smaller. By hand 'drill' down into the quick of the nail. The blood will gush allowing you to know you went far enough and more importantly, release the pressure and thus relieve your pain.
I just subbed. Cool build. Don't worry about views. You have cool content
I always use a sterilized hot needle to relieve pressure under the nail.
Great channel. One thing missing I believe is a good Cat maintenance &Repair manual.
You have now got 9 viewers, an interesting project.
Just subscribed!! I have a 1950 d4 7u its allways nice to see these videos, specially cause it seams that i use my d4 for an hour and it allways breaks so then i gotta figure out what to do to fix it. I think My generator just got seized up so im thinking of just removing it and putting a cover plate in its place . Hopefully it will work. Anyway keep the videos coming !
I’m not a mechanic but I do enjoy what you are doing. Keep it up, you have another subscriber. Oh, the ducks? Too random, but nice. Saw your finger in the next segment. So sorry, but glad it’s over now!
should done the hot needle poke relieve the pressure, would of felt hell of allot better. Not bad, learn by doing, it only way to go, don't give up, if before you think it's wrong check your facts with other, internet is great. not always correct but it does get you heading in the right direction, Nice work.
Timing cover fuel pump must be in sync to squirt diesel ,pump is gear driven in timing cover bolts hold drive gear to pump also time cam all time marks must be in specific sequence or pattern with crank .
Great real videos highly entertaining bing worthy Nice Job!
Realy hard working lonely... Woow n keep becarefully mat
Matt, You are on a great learning adventure. You need to get famitiar with a tool store called Harbor frieght.
De por si se debería considerarse interesante ya que el mismo trata o busca llegar a lo más profundo de los detalles y no importando la opinión negativa de cualquier persona que pueda tener sobre los videos, yo estoy seguro de que algo positivo le podrá encontrar a los mismos.
Pero hubiera sido muy bueno un número o capítulo en él principio por cada video para poderlo seguí en todo su desarrollo.
De por si encuentro interesante el empeño y dedicación que le presta a su proyecto y por mí parte esto es un 10.
Thanks!
Wow, thanks man!
Other TH-cam creators have injured a nail. They have posted many ways to relieve the pain.
I nipped two of my fingers like that some years ago, OUCH! an army medic heated up a needle to red hot and pierced the nail to burst the blood blister under the nails to reduce the swelling.. I got a bit ill watching it, but couldn't take my eyes of it. Lost both the nails but they re-grew over the next few months. It'll continue to smart for a while yet but you should get the swollen finger pierced to save your under-nail.
Drill a very tiny hole (can use hot needle) through the based of that finger nail to release blood pressure under it and it won't pain any more - from experience. But yes, you will loose it. Congratulations on getting the motor disconnected.
Drill a small hole in the nail to relieve the pressure behind it and the pain should decrease. A very small drill bit turned by hand should work.
For the YT algorithm, your title needs something like “Rescued after sitting 10 years. Will it run?” Similar wording got me subbed to WatchWesWork, Mustie1 and MartyT.
Don't forget to capitalize random words in the title too!
