I love this stuff. You explain things and I'm thinking....yep, yep, uh huh, yep, yep, ....wait a minute.... oh yeah, yep......
CAT parts man 74-09.
I have touched each of these past. They were brand new and covered with Cosmoline.
Matt, we have been experiencing withdrawals waiting for your new video. Thank you for the posting. Another great video.
Ole School mechanic myself, you are doing a great job identifying the causes n related problems. In today's shops, most are misdiagnosed n just parts replacement mechanics. Not many mechanics could go as far as you have without guidance imho. If a guy doesn't understand how equipment works especially under load, they can't accurately determine the cause of the problem. Enjoyed watching your video, n probably the first time I've watched one that doesn't involve cuss words every other word.
"if we survive...." Well it's great to see you working on something to keep your sanity, then be able to watch the dog go insane attacking a sprinkler. Absolutely enjoy each episode!!
A bearing went bad on that left side final drive. That's what chipped those teeth. A discussion was probably had about plenty of mating surface left on that gear, and just the bearing and seal were replaced. I've seen that before with older machines. Like how much do you really want to spend on this old machine ? was the question being asked.
I has thinking the exact same thoughts when Matt posted the initial photo. It was probably an expensive part pack in the day, plus you had the cost of down time.
I've been waiting for another video! So glad to see another post!
Thank you for the posting.
Well there is a new appreciation of how those things are built.
I have had a bearing failure in a final and the gear picked up a bearing and took out teeth on the gears. Might be old damage and it was put back together with that damage to the pinion gear which it would still work with the small pieces out of the teeth.
I think you hit the nail on the head.
That's what I'm thinking also.
That's what I thought.
Maybe they replaced the big gear from the outside? Removing the track, drive sprocket, etc. They couldn't do the small gear from there, so didn't change it?
Wow what a Christmas present , another video from Pacific NW Hillbilly and on top of that Im the first view. Hey Bud, what is your German Shepard's name?
Charlie
@@PacificNorthwestHillbilly cool
I am enjoying the failure analysis in addition to you making tools you need. When you said that you have new seals that fit, it reminded me of Carl the Bushwood assistant greenskeeper: "...when you die, on your deathbed, you will have total consciousness...so I got that going for me."
Was stoked to see a new video! It’s coming together nice! Also - I just bought a box of 100 black HD nitrile work gloves off of Amazon for like 25$. Worth it for sure to have quality work gloves especially when handling heavy grease/oils and cleaners.
A trick I use. I wear 3 layers of blue nitrile gloves. If top layer breaks I can easily swap out the glove without fighting sweaty and grippy hands. When I finish the work, I toss outer layer and leave inner two layers on corner of the table. Next day i first put on pair of clean new gloves and top them with yesterdays two layers of cloves. I like clean fingernails...
That gear damage is old and was probably caused by the small bearing failing. The original repair cleaned out most of the bits, installed a new bearing and re-used the damaged gear. Given that the dozer will probably not do 10,000 hours in future that gear would have held up.
Well done. Waiting for the next film. I always manage to learn something new in each film.
I don’t know how much experience you have with those machines but you are doing a great job
Have yr selves a great Christmas, seasons greetings from NZ
NIce job on this video. Excellent explanations and thought processes while you disassemble and then reassemble.
I just can't get over all cast parts on this dozer. Cat must have had a great foundry or vendors who cast all those parts in an economical manner.
Great work glad I am armchair doing it 🙂. Merry Christmas.
Thank you for your willingness to be through. While I am 60 now - I may have a communal rebuild in the next 20 yrs. Your detail allows my revisit to this - 40 yrs after we acquired our Dozer. Cheers to you SIR - and your willingness to document this!
Love these videos. Merry Christmas
The amount of force on the spring packs is just crazy! A one dog treat job, ha ha ha. Things are going fine, thanks for posting.
Looking forward to the next year
Wow. Matt. Its incredible how far this has come...to tear dwn, evaluate, replace and reinstall. WOW
He says I don't want to hit it with a hammer because there's a bearing in there.
A few frames later he brings out the dead blow and starts hammering on it. 😆
Wow big brother, your really doing it right... all those parts are mind boggling... Kudos.. 🇺🇸 I have no doubt it will be running soon...
Matt, I was so happy to see this post as I just knew that drama was waiting somewhere for some dang reason. Its like no good deed goes unpunished. Charley must be close to one of the most happy dogs in the world. You really pay attention to the littlest things that could hurt him... very impressive. Merry christmas
Thank You for the info on the 938 bar and grade 8 all thread, keep up the great work!!!!!!!!
Merry Christmas! In Finland we say hyvää joulua! I enjoy waching your videos about this d4
Great work. Thanks for sharing your adventure.
Real progress - Merry Christmas.
I've been waiting for this update on the DR project.
You're doing an outstanding job with the rebuild and it's nice of you for sharing it with us.
Thanks Matt.
Merry Christmas to you and your family.
Great progress Matt! Merry Christmas!
Good to see you and Charlie thrashing on the bulldozer. Charlie is a good helper hound. Merry Christmas from Texas y’all
I lost my helper about 2 months ago. I miss him.☹️
Thanks for all the great videos. The repairs are really coming along. Merry Christmas to you and your family from the East Coast.
Thanks Matt,
Happy holidays!!
Your efforts are very great in conveying the idea, thank you very much
I really appreciate the good job you are doing!
Good luck on the build, its looking great.
Matt,
A little trick to remember when that final clip (eye gouger) will not seat properly from uneven thickness or just a hair too thick.
Take a pane of old junk glass and rub on an area on the glass with - valve grinding compound-. Now lay the ring on the glass and relax to music while doing “figure eight” patterns to even the ring and reduce thickness. Also a good way to polish off old crud. Push down evenly and move your hold down area often. Use plenty of VGC.
Good Luck Matt, & Merry Christmas!
Good to see it going back together ! Hope you and your family have a great Christmas!!
Excellent progress!
As soon as you said that my mind said “Cotton Eye Joe”. Great!! I suspect this is all prior damage. Hertzian (contact) stress causes pitting even without foreign bodies being present. It’ll be fine for a hobby dozer. All looks very clean indeed.
Another GREAT video, thank you sir!
You are doing a nice job. Take your time, and enjoy the process. Looking forward to seeing it under its own power.
Found your videos late in the rebuild. Have enjoyed watching and have also had a few laughs from them. You have sparked my interest in doing one myself. Most enjoyable. Thanks, Donald
I really admire your do it right ethic. Stay well and enjoy the holiday season.
Great job fun to watch have a merry Christmas
its rebuild is moving along thanks I enjoy watching your progress! Merry Christmas
Coming right on along, be running before you know it. Great job
I have been watching you from the beginning & this is some very interesting & exciting stuff. You sir are one of those rare stone.
And one hell of a mechanic, this project is way cool, way cool, can't wait for the next installment/video. Here is wishing you & yours
A Very Merry Christmas & A Very Happy & Healthy New Year's !
Glad to see your project is getting more together with time and wish you well with your D4 learning skill.
Matt, enjoy watching your videos. Keep them coming. Have a Merry Christmas, and a Happy New Year.
Wow, what a lot to do, but it looks simple when you do it. Hope Santa brings lots of goodie’s for you..
Nice to see it coming back together. Hilarious to see to see Charlie attacking the sprinkler.
Merry Christmas, Matt.
Your project is turning into a labor of love.
Slowly, with attention to detail, it will all come together.
Thanks for sharing.
Better get on over to
western truck and tractor repair
and give Warren a hand with his D4 steering clutches and bands!!
looking good Matt- keep up the good work - i can tell you're excited about this after the interminable teardown.
Pulling together nicely , merry Christmas to you and yours and a happy new year thereafter.
Absolutely beautiful shop!
Been watchin your videos for a while now, love seeing these old machines rebuilt and getting a new life.
One thing I can say is I enjoy your videos about this model of cat. If I could suggest something if you were to jack up one side of the machine, shore it up possibly, you could rotate the tracks by hand to make it easier than pulling or pushing the the machine back and forth.
You got the good clutch too from what I’ve heard those last a long time and don’t rust stuck as easily as the factory style hopefully it will be a great machine I’ll keep watching buddy thanks for sharing
Thank you Matt. Everyone of your videos is interesting. I am a chef by trade, but I can’t stop watching your episodes……. Great job and total respect
Merry Christmas and a happy new year 👍🏻
Fantastic Matt thanks.
Oh, My. That final drive is almost mint. Very good.
Can't wait to see this thing riding around. You've come a long way. Merry Christmas and a Happy Newyear from Holland.
I have enjoyed all of your rebuild videos. I love bringing things back to life myself! Good to see there are other people that don't mind digging into things, and getting their hands dirty. Kep the videos coming. Tim in Kentucky
Well done. Wishing you a Merry Christmas and all the best for the next year.
Thanks for the video!! Project is coming right along. I'm learning things and I'm an old dog lol. Anyway, thank you and have a Merry Christmas to you and yours!! Looking forward to see this baby run
Hi Matt.thanks for sharing this video with us. Merry Christmas and a happy new year to all. May God bless us with another great video from you.
This may be the most mechanically sound D4 in existence by the time you get done.
Super interesting. Well done.
Merry Christmas and Happy New Year, Matt! You WILL get this baby running and it will be your pride and joy. I look forward to your videos of this machine working your land. No hurry. The rebuilding videos are also fascinating. Thanks!
Ooo there's reasons there's always reasons but no one knows what they are🤣😂😂🙃
Really great stuff. I'm looking forward to the next installment, just like I looked forward to this one. Oh, and Merry Christmas to you, the Cat, and the dog. 😃
This tractor just keeps on giving surprise after surprise!
Here's wishing everyone a merry Christmas, & a very happy New Year!
Thank you and merry Christmas. I am watching your videos and not the stuff on tv. Not only do you have great mechanical skills, you have great improvisational skills and video editing skills! Keep them coming. Stay safe.
Slowly coming together! Take your time and do it right. Merry Christmas!
I just wish the so-called experts would give you a break from the negative comments, it’s Christmas and your good enough to share this with us Matt! I appreciate everything you do and you’re trying, I could do this and the ones that can should help and respect you or haul a###s outta here! I apologize for my temper but I can’t stand video CRITICS! As always I enjoy your videos and appreciate you sharing with us Matt! Waiting for your next video brother! 👌🏻🤙🏻🤙🏻

Thank You.....
I enjoy each video.
Merry Christmas Matt and Charlie. Glad to see the new video. Was missing the content from you . Hope you have a great New Year as well .
*- [MATT] Great tutorial about how the hug clutches work to engage drive torque.*
*- How come the left side did not pop at **28:40**, like the right side did at **29:07**?*
*- And, yes, the paint does look great. That makes all your hard work and effort feel rewarding for me.*
Merry Christmas great Video. Thank you for Sharing... :)
Hi Matt, I started watching one episode of rejuvenating the D4, so I naturally checked the channel and went to your playlists and found where you started this project. Wow what a ride. I could not stop watching video after video. It was the attention to detail that kept my attention. This looks like a manual on how to rejuvenate a 1950 D4. I am now checking daily for any updates. Cheers and congrats on your project
Merry Christmas. I am learning along with you and when I get my D4 I’ll known what to do and what not to do, such as losing my nail! 👍 Happy New Year!
Your an a amazing man. Very talented. I am so looking forward to finish this journey with you and watch you drive it for the first time. You should be very proud of yourself. Merry Christmas. Hope ypu and your family have a great start to 2022. See yo then. Take care Andy perth Australia
