Love your understated and dry sense of humour. Got me laughing quite often. Love your Sheppard how she checks in at the most appropriate moments possible when you're balancing a ton worth of motor or trying to move something that she figures she should help you with lol Great stuff. Can't wait to see this girl all fixed up and ready to dig :-)
Well impressed with your decision to tackle the control block. It definitely needed to be done. Cinematically impressed by the shot of you struggling to pull the block while the well sorted bulldozer shines in the background. Ive thoroughly enjoyed watching your skills develop.
Matt's patience and persistence shines.
Agreed. I always look forward to his videos!
Your courage to tackle such a big project is inspiring.
100%
I agree.
You're 1 smart cookie tackling this rebuild Matt hats off to you.
Genuinely a heart like a lion here, that or bloody mad
I am impressed by his courage and tenacity. My grandfather always said not a lot to lose in this situation. Its not going to get any worse by trying to fix it.
Matt you are incredibly patient. Your rebuild of the bulldozer was beautiful. I expect this will be the same.
I cant believe you dont have a million subscriptions. I love watching you work more that watching somebody getting their vehicle pulled out of the mud. Keep up the great work!
Another great video! I love that you aren't scared to tackle these massive projects, and that you're willing to take us along for the ride. You explain things well, have a methodical approach, and your sense of humor has really begun to show in your videos. Keep up the great work, and I'm looking forward to the D4 cold start video from your survey!
You are a brave man tearing into that thing. Great video as always!
There was a day I would have jumped right in, but my 70-year-old brain just can't let me now.
@@ClintsHobbiesDIY my 70 year old back agrees.
My 70 year old wife feels the same way!
The first tare down of an excavator I've seen on UA-cam!
Great episode Matt. I liked when you mentioned that it actually took you week to get that far. That's good insight as to how much time you really spend on each subsystem. I not been exposed to heavy equipment so everything I have learned has been from your channel. Looking forward to the winter videos. Happy Holidays.
*- YES, agreed, I heard That, too! I am glad you mentioned it. Thank you.*
That's one hell of a project you got! You seem to have the tenacity to complete this job.
You are definitely a glutton for punishment ! What a huge , nasty job. To not mess with it in the winter is the smartest decision you have made. Keep up the good work thanks for bringing us along. You are an inspiration for sure.
I see a forklift or a tele handler in your future, Matt. That poor tractor isn't really cutting it...
Amazing job!
yea he could use a telehandler real bad.
Well done, Matt! I've done similar tedious jobs with lots of electrical cables and used Panduit cable ties that have a white tab on the end that I can write on with a Sharpie.
I would never get that back in order again, I really admire your work! Love your videos ❤
This has got to be a labor of love for you. I'm SO impressed at your willingness to tackle the hard stuff. I can't wait to see this baby all cleaned up and purring like a kitten! I hope you have a hydraulic hose pressure testing rig set up so you can test all your new hoses before you put them back in. Staying tuned!
Your a brave soul. That valve block is going to be difficult that's for sure. Great video.
You are working like an old-fashioned millwright. Be glad it's not snowing !
Next step... 10 Gallons of de-greaser + a hot water pressure washer.
You are going to end up with a good machine.
It was obvious from the 'dozer series that Matt isn't one to shy away from big jobs...
However, I'm mildly concerned about his NEXT project once this excavator is back to pristine...
The +next_ is probably a nice 'simple' one such as building a track-loader from the ground up...
(And when I say 'ground up', I mean that Matt will begin by creating an iron-ore processing plant to produce the steel that he needs).
Impressive stuff sir... Keep up the good work!
Hats off to ya Matt, editing is already a pain so to edit out all the zip tying too, wow, thanks for a great video.
By the time you're done with this project, you'll be able to get a job in Kernersville, NC at the factory 😁
Electric motor is for the auto throttle function. Some machines have contacts on the joystick handles that speed the engine to the setting of the hand throttle position when you grip it and return to idle when released. Nice function for certain situations but not always needed. Libherr used it in the 80/90’s. Handles had gold rings around them that were the contacts. Make absolutely sure when making the 4/6 wire hoses with flange fittings that they’re aligned correctly before you crimp the opposite fitting. They don’t twist much and too much rotational pressure will cause the flanges to crack and break where they are welded. Not to mention you will have a hell of a time getting them connected. If possible you can crimp one end on and put it in place on the machine with the other fitting in place but not crimped to get the best fit then mark the fitting to the hose to get the proper position. Depending on the brand and type of hose and fittings you use you may have to skive the hose and you may need different dies for the crimper. 5000 psi hoses are more challenging than 3000 psi hoses for a dyi. Of course I haven’t made any 4/6 wire hoses in over 20 years now so I don’t know if anything has changed since then. I used Weatherhead brand then. Not familiar with any other but Parker 2 wire for the last 22 years. On the final drive motor the small hose is probably the brake release or a 2 speed function and the top is probably the case drain. Consult the hydraulic print if you have one. You can probably get a digital manual on eBay for the machine if you don’t already have one. At this point you should strip it on down and give it a good cleaning and fresh paint where needed. You should be able to disassemble the valve stack and clean and reseal it with no issues. Valve in back is for the thumb most likely. I enjoy watching and looking forward to the next show.
As a child, when my parents wanted to shut me up they used to give me a bundle of string to untangle- I used to love it. With all those pipes I think you are definitely out of the same jar.😊
The little valve under the boom is the crossover relief valve block. The blue electric valve back by the pumps would be for the thumb, generically called a DO3 valve.
Here is a trick when filming welding grinding paint ect.Use old trypod from light what have you.Place piece of window glass in front.Important :use zip car wash soap to wash glass 1shot glass to ice cream bucket soapy water.Dust particles ect will not stick to glass also nonscented baby wipes work great if you do need to clean in between shooting.Enjoying your series.
Bravo Mat...It is a HUGE undertake this "renovation".. Too many problems to solve but I'm confident, you'll successfuly finish it.. Many thanks for this video also...I hope we'll be able to see some other videos regarding the other pieces of it, like the motor or other parts during the winter.. Hope you to be well and to see your videos, soon again..
You're the only channel I don't watch straight away, instead I wait until I'm settled and know I won't be interrupted, so I can relax and enjoy a delightful glimpse at a truly dedicated and knowledgeable craftsmen at work. It always makes me smile when you thank us for watching, I wouldn't miss it for anything.
Same here. Never watch one of these until settled in in the evening.
Man the struggle bus ride was good this week. This is a turning point once you get it clean and sorted out
And then Matt said "I'm feeling lazy" yeah, while were all sitting around with our feet up watching you bust your a**... Your a very hard working man, great video's and much respect sir!!
I always like to take things apart to see how they work, and i can usually get things back together. But this! Holy crap! what a complex system. I admire your ability to tackle this beast.
Great job sir. As a millwright best long handle 1/2 inch drive ratchet for me has been Armstrong brand. Only one I ever needed after all the other crap ones. It was no stranger to a pipe snipe
A daunting task, Mr. Matt. Thanks for another great video! Moves along nicely.
I think you need to change your name to: Harbor Freight Hillbilly! :) Love your work Matt, no job is too big or too small!
Those old Williams tools are the real deal. And the company is still in business! Boy, I don't envy you the cleanup on that gunked up chassis Matt.
Thank you Matt. Always enjoy your content and videos. Looks like you’ll be a little busy this winter. Hope you have some heat in there. Take care.
Holly Smokes Matt! I was impressed with the D4 project. This is next level. If you actually manage to get this beast back together, you'll get the award for most complex project ever completed on UA-cam.
It's a big "if" on that one, lol
Matt, I think you did an outstanding job recording your disassembly. Seems to me to be a tedious task and to add cameras and video recorders is a whole added dimension. Although it does help in the reassembly process. Between the engine and hydraulic manifold,
it should take a good bit of the winter to finish. I enjoy watching your videos.
Thanks for sharing Matt, good to see you my friend! Looks like it’s going well as expected brother, at least you have almost everything disassembled and moving forward! Good luck with everything and stay safe, warm and healthy throughout the winter my friend! Kirk from Louisiana sending prayers and good vibes to you and your family throughout the holidays and winter months! Take care Matt and thanks again!🙏🏻🙏🏻🙏🏻👏🏻👏🏻👏🏻👌🏻👌🏻👍🏻👍🏻🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸GOD BLESS AMERICA 🙏🏻🇺🇸🙏🏻🇺🇸🙏🏻🇺🇸🙏🏻🇺🇸🇺🇸PRAY ALL THE HATE IN OUR GREAT NATION ENDS SOON 🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🙋🏼
Wow, what a complicated nightmare of a job. Hats off to you Matt.
PNW Hillbilly - The World's hardest-working nocturnal heavy equipment restorer!! And don't feel bad about the cold. I moved FROM Portland/Beaverton and this a.m. it was 7 degrees BEFORE the wind chill factor.
I do some little things and shudder at the thought of taking apart a pendulum clock, man the guts and courage to tackle that block is way beyond words. Thanx.
Great videos. Thanks for sharing. You're dedication to the depth of this rebuild is amazing...here's to your continued success. Merry Christmas & Happy New Year
You have big cajoneies…..taking on this project! What a nightmare it’s gonna be matching those hoses up! Very brave ! The world is watching you…..don’t drop the ball!! Enjoy your vids.
I've seen you strip down and rebuild that beast of a Cat dozer, and I'm convinced you'll be succesfull with this machine as well :D
Your doing a great job. If anyone wants to complain about you not working In the cold, let them deal with the cold. I'm like you. Work in a warm location... Sorry I was one that questioned your working in the rain Thanks for explaining it...
Matt, Excellent work and especiall on the organizing and marking those lines! Looking forward to the next video!
Where’s the other video we voted on. I can’t get enough of your videos! It’s motivated me to get off my butt and start fixing stuff around the house!
Keep up the great work!
I've worked on some filthy trucks and boats before, but that thing is nasty! I hope it is more clear in person than on video, but that is a maze of hoses and paths they have to run to avoid damage. Wishing you all the best and admire your work ethic. What you need is about 3 or 4 old coots like me to be standing around giving you advice. That would really make it better!
Good job, keep it up. I am still in awe of you courage and ability to take on these projects. 😀👋🇬🇧
Man,
no need to apologize for not putting out a video that was supposed to be one thing, and then you end up with a different video…, I think we all just love getting to live this rebuild vicariously thru your work.
Was great to hear some of the tools you are using, are handed down to you by your “gramps”… I am 60yrs young.., and ain’t got no “gramps” around no more (miss him everyday).
Great video,
Thank you sir.
When I was an apprentice back in 74 I used to clean a lotta machines prior to paint, was damn hard work! I’m sure you’ll get that machine running and looking like new! Or close! 🇦🇺🤣🤣
What a nice guy Matt comes across as. If you want to clean all that dirty electrical stuff. Remove all the larger bits of crap from around it then use a vac and brush to clean it out then spray it all down with lots of brake cleaner or isopropyl alcohol.to dissolve all the oil and grease.
It is good to get that spiders nest cleaned out for just the cleaning. That block need inspection. We all look forward to the next go round. Thx for the vid. High^5
Your color coded tie wrap reference reminds me of how we keep track of the count of the 25 pair binder groups of PIC telephone cables. Good idea, Matt!
Wow Matt!! I never thought I would see another color chart Prang would be proud of you right now. Okay that was more for old Art Majors like me.😄
I commend you 100% for tackling a project this big yourself 👌🏼🤘🏼🤘🏼
I was exhausted by the end of this video. I just kept thinking “thank god I don’t have to figure out how to put that thing back together “. You are a work animal.
Really looking forward to the next video Matt. Joe.
i hope youtube paid for this re build. the most solid rebuild i have ever seen tyvm, im so happy i found your channel
No way I would ever be able to tackle a job this big! Hats off to you Matt for taking us along for the ride! I have watched your D4 rebuild as well as Squatch253’s D2 and those actually made sense to me, but this excavator………………..no way!
This will end up the cleanest digger ever..can't wait till the summer when you roll it out !!😀😀😀
*- Matt, I don't know how to get across my appreciation of all the challenges you take on.*
*- Trying to do the block removal sure would spook the heck out of me.*
*- I hope my encouragement works as support to you.*
Parabéns teus vídeos são muito bons e bem explicado. Abraço aqui do Brasil 🇧🇷🇧🇷🇧🇷
I know what its like to work outside in the cold, Maybe its just a Canadian thing lol. Good work though keep up the great vids.
A cinch. Only took 34 minutes.😁😁
Attaboy Matt.
Great work, in awe of it. The lives of many zip ties could have been saved with a label printer :), I have just bought one after spending the last week digging in my USB cable box looking for the cable I need....
I will tackle most anything but this one’s giving me anxiety. 😂
Nice work as always, here's a tip for hydraulic lines, if you have an air hammer hit the fitting on the line with the air hammer and it loosens them right up.
I can't believe you are taking on such a complex project. Good for you!
Very inspiring that you tackle this huge project, I think its a big job to strip a motorcycle lol
You comments are great. I learned a lot. Not just not just grease monkeys. A project like this is very curious too all. Thanks
"I'm feeling lazy now" says the man who is completely rebuilding an excavator!🤣 Love the videos and how you aren't afraid to tackle such a huge project!
Invest in a golden rod to put under the tarp. It will help keep it dry through the winter. 😊 Big job ahead on this project. Interesting indeed.
Thank you Matt that you sharing with us with these great stuff.
You need to wash the grey down with something, I agree. It's pretty filthy but it'll stand until you are ready to refit everything. In fact until such a time; it's better having all that oily muck all over! Well done. It's tough in the dark and damp even without cold. Keep it indoors! Until next time.
Great job with the disassembly Matt. I know that you needed to strip out that valve block, but man what a time consuming task!!
You are doing a great job mate, keep up the great work. 👍
What a mission. Doing an amazing job + filming. Hats off Matt
You did a great job on this video, Matt... no worries. Your spreadsheet idea was genius... you must be an IT or accountant nerd. 8-))
I know Matt is NOT doing this for the clicks, but can we all send his channel to 100,000 subscribers already? I've been with him since the first video of the Dozer. I send his vids to friends that would be interested.
Appreciate the content, Matt. Thanks for taking the time to film it and edit it and post it for us. I work on my own cars and motorcycle (I have 6 kids and 5 cars) so I enjoy seeing someone like me that just researches and works on their own stuff.
"...why am I DOING this... that's a deeper question..." LMAO. I love your honesty. Here's a thought, I've always admired this kind of equipment and never had a chance to use any, let alone work on it. It might seem like a nightmare now but you're living my dream brother. I envy you so much the first day you put this thing back to work - THAT will be an episode! Hang in there Matt, we're all rooting for ya!
It looks more complicated than heart surgery. We all hope your patient lives & works again. As well as getting all the hydraulic hoses connected correctly, I guess the path of each hose & position of each hose is important too.
Top spannering as usual, you've reminded me I need to attend to the leaking swivel housing on my mini excavator, ah the joys of second-hand equipment. Keep up the good work Mat 👍
You're kickin' ass and taking names Matt
This is going to be a next level full restoration by the time ur done mate holy moly
You sure will have a ton to do this winter . Lots of scraping and grease cutter around The sensatine electric and it should be fine ! Also with some Break Cleaner - Steam Clean in a can- . Excellent video and great job . Looking forward to the next one . Thanks for sharing !
Hi Matt. Don’t forget to find those two electrical connector retaining clips that flew under the machine before winter and more rubbish from the clean up hides them :) Cheers Ray
If you open your adjustable wrench all the way you can put the short end of your allen wrench in the hole of the adjustable jaw of the adjustable wrench. It's hard to describe but it will give you more control of your allen wrench than just putting it in the jaws of the adj wrench. If ya want me to send you a picture of what I'm talking about, happy to.
Wow valve block is a big job, I think I'd rather do a head gasket job than valve block lol. I wish I lived closer I would definitely stop by and give you a hand. I look forward to the engine rebuild, take care.
Good Luck, The only thing that comes to mind is Humpty-Dumpty ... At least you can look back at unedited video for help in reassembly as even with the color coded system the path the lines take to connect correctly and not rub or fray is very challenging. Ray Stormont
I don't blame you stay out of the cold and do your shed work!
I'm with ya Matt..i know you cant hear me but i'm cheering you on , i watched all the tractor vids too...great channel..
Keep up the great work! I understand that this may not seem like a lot since you're the one that is struggling through the process, however you have a lot of us "rooting" for you to succeed in your endeavors.
Till next time.
Stay safe & Healthy.
Peace. ✌✌✌
You're lucky that you had a metric crescent wrench, you also need an adjustable imperial crescent wrench HA HA thanks so much for the video
Finally, the subtitles were quickly available and I was able to follow your work. You definitely have work to do all winter!
I also would want to clean that area. It’s a heck of a job but worth it to clean that dirt and oil mess. That would make me crazy… good luck. Love your channel
Thanks Matt for another great video watching while eating dinner... Between the treats of Pacific Northwest Hillbilly new releases and letsdig18 nearly daily releases I've had a lot of dinners watching great talent and content.
I really, really wish I could pressure wash the Excavator for you! I enjoy cleaning messy machines so much, almost like a fetich of sorts. I bought a 4000 psi Craftsman with a 9hp engine over 30 years ago and still have/use it today for what that's worth. Rebuilt the pump 2 years ago. Still works great 👍. I do wish I could have bought one that heated the water but mine can handle using up to 150 degrees water from my water heater so stuff comes pretty clean! I live on the Iron Range in northern MN. Love the Videos, work except I wish I were assisting you. Thx, stay safe and please give Z a belly rub for me..😊
If the people that designed these machines actually had to work on them, you know they would come up with a better idea and solution to routing and terminating all those hydraulic lines ! Instead of that snake pit they have created now ! You are a braver man than most tackling that job !
Love watching you struggle as its so relatable to us mere mortals without flash workshops and toolboxes full of every tool on the planet, I just can't get out of my head the fact that fitters have to repair these things in the field with the engine and turning piece etc still in place, impossible
Awesome Matt.The drive you have to take on such a huge project.And it looks like it all after you've done a hard days work already. You Matt are a machine and i salute you
❤
