OUT-STANDING! Hearing that cat purr to life and then seeing it move under it's own power was awesome! Great work, and great perseverance Matt!!

I have enjoyed watching your journey getting this D4 up & running. I do hope you'll continue producing similar content - your laid back / non-commercialized style is something a lot of older channels are losing in favor of "shorts" & how-many-ads-can-stuff-in-oh-and-I'm-endorsing-this-so-buy-it-now. Seriously - your channel is great and this 61 year old guy has learned a few tricks from ya along the way.

We screw up & try to hide it or deny it, you screwed up and posted it for us if you edited it, we wouldn’t have known, thanks for being a Man of integrity ☕️🏍❤️

Way to go Matt. I'm 70 now , played on D2's, and other dozers, and just about everything made at that time as a kid in the excavation field. It was a great pleasure to watch you resurrect a great piece of American history. Can't wait to see it make it's first cut after it's rebirth.

Outstanding work Matt. Absolutely fantastic seeing it run after all your hard work, it sounded superb.

Thank you so much for sharing us this beautiful series Matt. Your work experience, technical expertise, and attention to detail is truly inspiring. I can't wait to see when your D4 is fully restored and taking commissioning works.

That start up smile was priceless. Congratulations. It’s awesome to see it roll in on its own power. Great job and thanks for bringing us on the journey

Ive been watching this rebuild since the beginning. I can't believe how much painstaking work goes into a small dozer. Hats off to you Matt. This is one of my favourite channels.

Best series on KZfaq keep up the hard work! Engine sounds amazing👌🏻

you deserve that Matt, you've done a brilliant job on it. you can't help but smile when it bursts into life. well done

In a hundred years this video series will continue to be highly regarded content. Really enjoyed this series Matt, thanks for taking us all along your journey.

I've been watching this rebuild for the last 12 months and that was awesome to see it fire up. I live in Papua New Guinea so you've got fans worldwide, can't wait to see it finished, but don't know what I'll watch after that!!

So nice to see all your hard work come to life .. been watching this from the start I didn't think it was possible from when you first found her great work !

Hard to believe its been 16 months. I've watched them all. You must be stoked up. Great job.👍👍👍

Matt, you should be super proud of yourself. Not only do you have yourself an awesome dozer that's basically new, but you know the ins and outs of the entire machine. Looking forward to seeing your new CAT in action

It is such a great feeling when a motor fires up after a rebuild.

Nicely done Matt. Big project with a great outcome. Hope you get many years of service out of the old CAT.

Man this brought me back! Excellent video! My dad restored an old 1952 D2 from ground up. Pony motor, and man that thing would BUCK YOU OFF if you weren't paying attention to the drop in front of you. Lost him back in 2009 and had to sell his stuff so mom would have some $$ in the account to live on. Brought tears to my eyes to see that dozer go. Strong work on this restoration. Strong work indeed!!!

Way to go, Matt! Like so many others, I’ve been watching since the beginning. So happy for you with all the hard work and learning you have done to get here.

Congratulations! Wonderful build. Enjoyed every minute of it!

16 months, Awesome viewing Matt, it has been great to watch this all happen

Somehow all the pain of restoring something like your D4 is all forgotten when it's moving on its own. Congrats!

Matt, congrats... What an enjoyable trip I took with you... Thank you...

What a treat, just discovered your channel a couple of months ago and binged on it. A real pleasure to see the engine start so smoothly, considering the state in which you've found this dozer. Congratulations!!

Great job on the rebuild!!! Next time, try sliding a piece of sheet metal between the radiator core and fan before removing the water pump - it lowers my anxiety when I do so...

Wow. What a euphoric feeling to get that old girl to chooch once again! Reminds me of my younger diamond drilling days. Great video, a pleasure to watch you work

I'm one of the thousands who are HAPPY FOR YOU Matt. Congratulations. It was awesome to see and hear the engine start and see the Cat move on it's own power. Does not seem like 16 months.

Dude!! Congrats Matt!! That was so epic to see it finally fire up!

It’s been a long road but I’ve loved watching this thing come back to life. Excellent work!

I grew up wanting to restore an old car but one day it hit me restoring an old machine like that brought me more joy and when finished it's much more useful my loader paid for itself 10 times over in the last 3 years, never needs to be registered, only needs fuel and maintenance!

RE; the winch gearbox, I am a retired mechanic, I used to work for a food processing co. We used a bunch of gearboxes that used square-cut gears, (also worm reducers), we filled the gearboxes with 100% STP. makes them quieter, and extends life. (Doesn’t stop leaks). Have also seen 5-gal cans of STP put into 16-278 GM DIESELS, on submarines in the Navy. Love ur videos! Maurice in TEXAS🤠

Congratulations! I've watched this from the start and enjoy every episode very much. Your low key manner and the way you edit and explain things makes this my favorite channel. Thank you.

I've been following this rebuild from the get-go, I'm amazed not only with your skills but the patience you have had. Simply AWESOME!

No better feeling after all that work! I’m proud of you!!

*- Thank you, Matt, for the striving you have brought us...& getting rain to christen the first start, too !*

Matt, you should be super proud of yourself. Not only do you have yourself an awesome dozer that's basically new, but you know the ins and outs of the machine. Looking forward to seeing your new BEAST in action.

It's great to hear the old girl fire up, she's sounding great. All your months (years) of hard work have paid off, congratulations.

Turned out way better then I thought it would….Looks great!

HOORAW!! ya got yaself a runner there matt - you go son!! v that is too cool matt- thanks for taking us along for the ride. been a good one.

I've been binge watching this story to get caught up with your content. I am not a mechanic (at all) but this has been so entertaining. I actually clapped when the dozer started running in this episode! Your smile at about 41:30 told the whole story. It was nice to get 43 episodes in a couple of weeks, rather than 16 months. :)

Congratulations, Matt! First start was beautiful! Can't wait to see the D4 work soon!

The moment we’ve all been waiting for. It’s been a long ride and a bunch of us have been here since day one. This right here makes everything worth while. Thank you for taking the time to document and bringing all of us along on your journey.

You absolutely deserved that smile at the camera. Ive been following since the recovery. A hearty well done!

Matt you should be proud of your accomplishments bringing this project to this step.

So amazing to hear it run and see it move under its own power!!! Congratulations!!!

Yay now working on the excavator is getting closer.

You have to be very pleased with yourself for such an enjoyable result. Having that engine burst into life was music to the ears. Thanks for the video.

That is such a northwestern winter day!! I can just feel the cold

There was nothing "downer" about your video! What an amazing job you did to get that dozer restored and back together. It's almost ready to use. Pat yourself on the back for the determination to bring life back to that dozer! Well done!

I'll bet all the mechanics at CAT are watching this.!

it was a treat just to hear it run its smooth

I was not prepared for this 😯 Thought that it would takes at least another 6 months to see it driving by its own. Love your work and learned so much. Thank you for sharing!

Great series, great to see it start and restart and move under its own power, a restoration/rebuild well done, I salute you sir, thanks for the update.

SO PROUD of you Matt!! What a wonderful project you have shared with us. I SO LOOK FORWARD to seeing you push some dirt with this. Time to bend your homestead to your will. What a GREAT TOOL to do that with!! =) CONGRATULATIONS

The smile on your face says it all. Congratulations and thank you for sharing your journey. Couple of final tune up jobs and a battery box where the old pony was and you are going to be pushing dirt or snow.

Watching again, three weeks later. Your pullers remind me of my former work: High School Band Director. When brass players would inadvertantly slam their palm against the rim of the mouthpiece, the mouthpiece would stick into the brass instrument they were playing. The mouthpiece puller is most reminiscent of your smaller puller. Just a nutty memory. Hope you and my fellow commenters don’t mind.

Great work Matt. Been watching you struggle for months and it is exciting to see the D4 running so smoothly. Now on to a salvage D6!

Matt, here's an old trick to protect a radiator core from fan damage. Before loosing any bolts put a thick sheet of cardboard or sheet foam (better) under 1/4 inch plywood as space allows between the fan blades and the core. You won't have to worry about damaging your core. So friggen cool after all the struggle bus issues that you had to work thru that big beautiful beast fired up after a couple of oops and she ran so smooth. A couple of more episodes and it'll be pushin' dirt. Then it's on to the excavator series. You're definitely right up there with Squatch253, Watch Wes Work, Diesel Creek and Mike Dirt Perfect quality to watch your wrenching and the work you put in to get your dozer running again.

I was hooked to see it run again when it was in the woods. Way to go Matt.

GREAT JOB MATT!! This has been the most interesting time to watch! Ive never done a CAT but plenty of gas tractors. First start up is great to see your smile!!

Man I'm grinning ears to ears to see this finally running. I can only imagine how happy you are at this moment! This has been one amazing restoration!

Great job Matt! Been watching this project from the beginning and gotta say I enjoyed every minute and the care you've taken to do everything right. It was very satisfying to see if start up and boy it sounds great! I appreciate you letting us come along on this journey with you and taking the time to record and edit all the videos. Can't wait for the next one!

congratulations! I know the immense sense of relief and elation that follow the initial start-up. It's like counting your newborns fingers and toes to verify they're healthy.

Congratulations, I have followed you from the recovery of this lucky bulldozer and enjoyed your comprehensive restoration along with detailed explanation of the work involved. Thank you sir. From Australia.

Very enjoyable the whole process. Each video giving us a detailed account of your progress must have stretched out the rebuild. I know you will have this as a record but sharing it with all interested viewers like me appreciate your efforts. looking forward to you working on the finishing details and giving that D4 awork out.

Congratulations Matt you deserve this success. Your patience is an example to us all and your film making makes this one of the more satisfying videos on you tube.

Nice to see an old machine like this preserved. Well done.

I was your super cheerleader when it fired off. Great work Matt!! She almost ready from some grunting work.

Great to see it running! Congratulations 🎉

There aren't going to be any mounds or holes that don't get smoothed out pronto on Matt's place anymore! Nice! Thanks for letting us look over your shoulder on the project.

You performed a miracle. That cat was hurting every way. Good Man

I've operated plant for over 36 years and I must say you have done a brilliant job of that old girl, congratulations Matt 🍻 cheers..

Awesome job! I especially like the tip on using air pressure to prime the fuel system, file that under “why didn’t I think of that “. Brilliant!

All that hard work paid off it runs great. I don't think you could wipe that smile off your face. great job

OMG ! Hard to believe it has been 16 months . All of the hard work has paid off in a Epic way ! It just Purrs . No smoke when running is a Great sign ! Coagulations ! Thanks So Much for sharing your Videos with us .

Ah the sweet sound of success , she sounds great . A long way from abandoned in the wild but you got her there , congratulations man .

I was with you there Matt.grinning ear to ear ,when she start up and start purring like a new cat. good job.glad iam here form the start to the finish

Matt, you beat yourself up waaaaay to muck, 500 points for showing up and 500 points for making that CAT purr. I'm a fan . . . Thanks for the content . . .I learned . . .now push some dirt young man. . .

Excellent. Maybe we should call this its Birthday? Thanks for bringing us along.

Thanks for doing these videos. It’s been a pleasure to watch the journey and see her start up. Pitt Meadows BC

Glad I got to hear it run before I left for deployment

Excellent! I would have been grinning from ear to ear just like you were. You looked like a proud new papa when that engine took off and purred. :)

Matt, I’ve watched all your videos. I’ve worked on many tractors and dozers but never took the time to document it with a video. Its fun to watch and helpful. I had a d4 that the left steering clutch would get stuck open if the dozer was leaning downhill to the left and was able to diagnose the problem from watching several times your video when you rebuilt the steering clutch levers. So many thanks. Michael

That engine ran perfect. That had to be very rewarding. Good work Matt.

It's GREAT to finally see the ole CAT come to life!

Great job, Matt. That was a lot of work, thanks for taking us along. Now go get that thing dirty!

Bravo sir! Great sound isn’t it?! Remember: keep your hand clutch handle pulled back/engaged when idling in neutral - your throw out bearing will be much happier!!! You have been doing a great job on this.

Who knew a four cylinder diesel could sound so good 👍🏻🏴󠁧󠁢󠁳󠁣󠁴󠁿

The first start smile you had said everything. I really enjoyed this series, thank you. Looking forward to the video seing this work.

Purrs like a kitten! Beautiful work. Reminds me of my youth when I worked on these.

That tire tube for pressurizing fuel system is awesome. Great idea man. Definitely gonna have to use that next time.

That’s so awesome Matt, the smile on your face says it all👍long time coming you should be proud!

That’s great dude! So exhilarating when you light something up for the first time after a big rebuild.

Matt, I've watched this video several times now and it always makes me smile to see that beast turn over and start. It appears that you got a really good engine there. Thank goodness for that after all the heartaches you've had with this machine. Congrats on a job well done. You put in the extra effort and expense to do it right. I'm sure it will provide many years of use and enjoyment for you.

Nothing beats that first start.

Great example to see you stay calm and think things through successfully.

Wow after all this time the Cat sounds better than new .What a great achievement ,you should be proud of yourself, great work.

Moved under it's own power!! Not a downer ending at all. Great work! Can't wait to see it pushing dirt

Been following since the beginning of this cat project. I have to say I'm impressed and elated over your success. Kudos to you. With such heavy parts in a small garage, you made do with the simplest of solutions to an outstanding success. I thoroughly enjoyed following you, watching you overcome problem after problem. You got it done!

Subscribed from Australia. That is a work of art! Thank you for saving yet another Caterpillar from the scrap yard. 5 stars!
