When ordering those new coloured zip ties, I'd also add a large set of plastic hydraulic hose caps, to stop dirt and critters getting into your hydraulic system
Squatch uses a set from Cat I believe. He can;'t praise them enough!
The cat kit is actually the cheapest kit i could find, does a good job and each compartment has a part number so when you run out you can just order more of the sizes you use
Can you tell me where I can get BSP and whitworth sized crescent wrenches- my best mates next door neighbours dog walker said that if you buy a chineesium tool with US dollars then it automatically claims asylum and becomes neutralised. Have a nice day from the sunny UK😊
You know you’re gonna pull the engine anyways, so you should do it and get it over with so you can fix everything related to the engine underneath it. This will buy you a big piece of mind. Looking forward to the next video.
Agreed. He has pulled nearly everything at this point. Just clean it up, seal it and call it a day. It will be a brand new machine at that point.
I was thinking the same thing
My cousin, Billy, from Alberta was help me with a hose disconnect. I give him a handful of zips, and I said ‘disconnect all those hoses and put matching colours on’. After he was finished, he called me over and said,”I put all the matching zips, but I can see how that’s gonna help with nothing.” He had put two matching colours on the disconnected hoses, and none on where they connected. 11:44
I’d pull the engine if it was mine.
I wanted to enjoy a few days of being deluded before reaching that conclusion, but I think it hit me right as I was filming the ending.
You've done a amazing job so far. To be honest, your best bet would be to pull the engine out. You'll be able to address any problems with ease and you wont be fighting tight spaces.
The best line, " this is a big project". It's a bunch of little projects in a row. Keep up the great work!
How do you eat an elephant? One bite at a time.
I loved that. Just that moment of seeing yourself from the outside. I know that feeling.
One handed zip-tie. Got to give props, like a pro
Any tool suppliers watching, could you please sponsor this gentleman’s channel and send him some tools to review while he restores this machine.
You should probably invest in a cap and plug kit for hydraulic hoses
It would keep dirt out of the lines
Having your own crimper for hoses will be a benefit in the long run as you have other items
that need hoses from time to time . Initial cost is high but worth the expense in the long
run and beats having to wait to get one from another supplier. I look forward to your
videos and the various items you repair and restore to function.
"This is a big project." Understatement of the series and I thought that bulldozer was ridiculous.
You can combine two zip ties colors and then you have a greater number of combinations to catalogue each hose. You don't specifically need 10 different colors. You can even use 3 and have even more combinations.
Color code like resistors...
BBROYGBVGW
He has 6 colors and likely black and white at hand
that is 8^2=64 using two. Sounds enough
Helpful hint for marking hoses is to use telephone wire sometimes called telecommunication cable. Usually has a bazillion color combinations and they stay on and don't break or get in the way. Plus you can leave them on permanently for the poor soul that has to replace the hose in the future
Super IDEA ... never thought of this before ... you can pickup a 2 or 3 foot second of phone cable for peanuts at the scrap yard!!
@@MikeBaxterABC yep it works great even for tagging wire connections for easy reference
Been using it for years and works a treat, plentiful supply and better than using more plastic.
Not "technically" a Brazilian colors only 25 and they are in pairs, so actually 50 colors total.
The pair colors are blue, orange, green, brown, slate, and the tracer colors are white, red, black, yellow, violet.
For cables with more than 25 pairs, each 25 pair group is bundled with a colored binder following the same color code, eg, the blue/white binder group is the first, containing cable pairs 1 thru 25.
Buuuut, with this said, it's a brilliant idea and so easy/cheap.
Thank you for sharing.
thanks for the details!! @@thaddeustroyer
You’re doing a nice job, Matt, there’s a TH-camr captain in Kleeman rebuilding an old backhoe in order to loosen the hydraulic lines. He’s using an air chisel with a blunt end to loosen or shock impact the threads on the nuts, Hydro lines, look him up and try it. It works for him.
Captain Kleeman, a fireman working on his southern Indiana homestead. Interesting channel, as is this one. 👍
I thought it was a cordless hammer drill/chisel. I'll have to go back to check to be sure. He got the tip from Clint on C&C Equipment TH-cam channel. Also likely to interest some here.
One trick is to use a rubber glove and a zip tie to cover the ends of the hoses to prevent contamination. I used to have a brass O ring pick to prevent scratches.
ok if 8:30 isn't the most impressive demonstration of single hand dexterity I've seen in a while, I don't know what is...
a true artist at work
I noticed that too. He had oily plastic gloves on as well. Maybe he is actually a surgeon🙂
You have tackled a big job here but I can see you are not afraid of anything. As a lover of good tools the OCD in me cringes when I see a Cresent wrench turned so the force is on the adjustable jaw instead of the fixed jaw. None of my business but sometimes I can’t help myself. Enjoy what you do and your positive attitude. Keep up the good work!
Hi Matt, I have the same machine but it might be in a bit better condition. If I were to take on your project I would ensure that the hydraulics were leak free and spotlessly clean inside all systems first.
The engine should come out if you have the time and energy because you are going to hate yourself if you fire it up and then have to pull it for some reason.
Electrical is very important but Hitachi does make a kit to change some of the valves to manual mode.
After that it is on to pins,bushings and track issues.
Paint,windows and upholstery can always be done after the machine is digging and moving.
I am enjoying the series and wish you luck.
You do want to pull the engine way easier for all the repairs you are now getting into. Loved your cat rebuild and by the looks of things, this is going to be super cool as well :)
Great job so far. Your "even temper" approach to problem solving impresses me... it was so different than mine. I think you should invest in your own hose making machine. I think it will pay for itself over time.
Thanks for sharing.
If you want to save some of your struggles with hydraulics use an air hammer or similar to rattle the nuts before you try to. Loosen them. Try it you'll be surprised how much of a difference it makes
Agree, airhammer is the best solution. Works very well in Sweden.😊
I was going to say use a air hammer with a flat end bit directly on the hydraulic nuts. but some one has already mentioned it. Believe me it does work. I use to be a heavy plant mechanic when I left school in 1975, and it was one of the first tricks of the trade I got shown.
Plus one. But use a flat chisel point to vibrate the nut on the swivel joint. It can bite in and start turning the nut.
I wonder if a hair clipper/buzzer/shaver or any buzzing construction tool might have the same effect,
or if the low frequency of the air hammer is just correct for that size range of connections and fittings.
(the magic frequency seems to be around 5 to 30 hertz/impacts per second with about 1 to 5 lbs (0.45 to 2.3kg) of rotational force input.)
@@world_still_spins you go get your ball hair clipper and I'll grab my Snap On air hammer and we'll see which loosens the fitting first. My money in on the SO.
@@SuperSecretSquirell
We might need to suggest to Project Farm to try several different impact tools on hydraulic fittings.
(Or maybe TylerTube. Unless Matt wants to go get sponsored by some "hair" trimmer company and test various things on hydraulic fittings.)
Did you intend Wahl's hair and beard?
I've been working in 95 degree heat with high humidity, and I feel for you! Sometimes I just stand there and sweat! You do amazing work, dude - and that's hard when it's so hot. or cramped, or dusty, or greasy! On the hoses, I'm interested to see your decision process. I wasn't rebuilding the little backhoe that goes on my tractor - I was using it - and hose after hose ruptured. The hoses on that little machine run inside the boom, so I had to take it off to route them - and there's a cylinder in there, too. After I removed the boom to route the hoses and got the machine back together, the seal on that cylinder failed - and I had to take the boom off again!!!! After about 2 hoses failed, I replaced all of them except the ones for the outriggers. After the first seal failed, every other one did in a short time, except for the cylinder that swings the boom. It was uncanny - as though I had used the wrong hydraulic oil or something - but I hadn't. I guess it's age? The hoses were small diameter and around 6 feet long. I think they averaged $70 each - some came from Kubota and some from the local hose maker. Not a lot of difference in the price, if I remember correctly. Keep up the good work!
When it comes to replacing the hydraulic hoses I would definitely recommend buying a crimper and making them yourself. It's honestly very simple and saves a lot of money if you need larger quantities. Also saves a lot of running back and forth to the hydraulic shop because you'll absolutely forget some on the first, second and third try
If you compare the image @20:30 with the one @30:44 it looks like you'll have to do a 180 degree rotation to align with the body.
Hey, you can use an AIRhammer to loosen hydraulic lines Works quite good
Ground squirrels / red squirrels do the same things to motors here in Michigan. I had my Ram pickup motor packed with acorns. I smelled this woody burning smell after I was driving a couple hours. When I stopped for gas smoke was rolling out of my hood. They had packed nuts everywhere and on the exhaust manifold they were roasting.
It's nice watching your pragmatic way of analyzing the machine & the process to rebuild & fix it... you can cuss & get mad at it. 😂
Great job. I suggest you go ahead and replace/repair the wiring harness while it is near the shop. If any of it fails out in the woods, it will be much harder to repair and may even leave it stranded for the rust worms to eat away at it. Thanks for making the videos for us all to enjoy watching.
@1:51 - One should ALWAYS open a pack of zip ties like this. Brilliant packaging!
My wife dont understand why i watch stuff like this. I find it very satisfying and relaxing. One day im gonna buy a heavy machine and just redo the whole thing.
You have a beautiful farm, very picturesque. Nice drone shot.
Good luck with your project, looking forward to the next one.
I don't know if you need to pull the engine, but it'll make for great content all the same.
Definitely research making your own hoses. I think you could probably find a kit that would do a great job and save a lot of money. With the tractor, dozer, and excavator, you will probably be needing hoses in the future.
What to do next? There's so much to choose from, but this is nothing like the D4. I would look at your list of everything, and prioritize as you go. But write it down and keep it in front of you.
Looking great. Pull that motor, then you can have easy access to everything. Additionally, you can repair all the structure from the tree falling on it and repair the wiring as needed in that area.
“Might as well do it while I’m here” is pretty much the motto of your kind of channel 👍
With how expensive heavy equipment hydraulic hoses are, it almost makes sense to buy a crimper to make them yourself.
Keep up the good work! Really enjoying seeing this getting done in the PNW!
Simple Green is an excellent degreaser, just don’t leave it on paint because it’ll etch it. 18:15
Just be careful using simple green on aluminum. It will cause corrosion.
You don't know why? Having a working mid size excavator would be amazing... that's why!
Another great video! love this project and can’t wait to see it finished. Thought the drone footage at the end was awesome too! can’t wait for the next video, just pull the motor, its gonna need to be done anyway!
Your halfway from pulling the engine anyway if the wires are under it you should pull it
Last thing you want is wires shorting out
there's something cathartic about cleaning an old engine compartment. Getting dirty, making it clean. Positive results. Good job.
Definetly liked the way you got it out and restored it! Nice work!
Just for future use maybe, I saw that (Capt Kleeman) on YT uses impact hammer drill on those hydraulic connections and it works miracles!
Hey Matt, You can break the nuts loose on hydraulic line fittings by hitting one side on the flat with a hammer. You need to back it up on the backing opposite side with another hammer. It will break the threads loose. We used that trick all the time. Great video! 👍
If you can go to Home Depot…get the purple industrial strength degreaser….I work in a machine shop…couldn’t clean a machine without it…
Keep up the good work I really enjoy you projects!!!
Forgot to mention that it’s a Zep product
Take a glove and cut the fingertip ends off. Use those to cover up the hose fittings. Then secure the glove ends with the proper tie strap.
Pull the engine. Having it out will allow you to be more efficient.
Also, maybe renting a Hotsy hot water pressure washer for a day would do a better job of cleaning and quicker too.
This is a great channel. I really look forward to watching you tackle all of these projects.
My dad and I used to use a kerosene steam cleaner that got rid of every bit o grease. Not sure if they still make them, but they were like a pressure washer that propelled steam.
@@mikeswiney5317 The Hotsy's came in two versions I think, hot water or Steam pressure washers. I used both many times over the years in many different manufacturing plants. They just melt dirt and grime away. No need for degreaser with a Hotsy.
Fascinating to see this and what is inside one of these machines. The problem is if you do everything it will cost a fortune. I think a plan would be to pull the engine and anything else relatively easy to remove then sort the wiring, bodywork and cab interior. Finally rebuild it from the bottom up starting with the tracks and undercarriage.
I'd buy the hose crimper. If you plan to use machines with hydraulic lines it will pay itself in the long term, as you will burst one from time to time. As for now this excavator will need lots of new hoses, better to replace them while you have more space to work. I'm loving this new excavator series!
The easiiest way to loosen those fittings is to wail on them with any kin d of impact hammer. Just litely impact the fitting and it will loosen with no problem.
All those hoses and connections, you are a brave man!
Nice update 😊
Replace the wiring cos it'll prolly be as crusty as the hoses
I hate that foamy engine degreaser, I only use the regular stuff, not the foaming. Glad to see you used the zip ties on the hoses, it'll save you time later when you put everything back together. I know the hydraulic hoses will be expensive but it will be worth it down the road, just imagine trying to replace them with all the components in place.
For foaming degreaser, I’ve found the dollar store oven cleaner works just as Gunk. But ultimately diesel/kerosene mix in a handheld pump sprayer or good old break clean works the best over all.
yes love oven cleaner its the best
Always amazing to see someone who isn't in the business restoring a dozer and excavator. It is true that the right metric tool is an advantage, the metric system is another big advantage over the imperial system, which is much simpler, especially for very small dimensions. Otherwise a seamer, when you have two big machines seems to me a good idea and certainly quickly amortized.
Definitely buy a crimper, and then you can make your own hose. It is much cheaper in the long run.
Pull engine since your being so thorough. It will make everything SO much easier. Also, those cylinders are ready for resealing when you feel like it.
Everyone has their favorite degreaser but Purple Power Extreme has always worked great for me. It works amazingly well when you spray it on, leave it for 15 minutes or so then pressure wash or hose it off. Never was very happy with the results using WD-40 Degreaser. Anyway, great work on the Hitachi so far! 👍
Great to see that you have found a steel frame under all that grime. It's such a big task I would pace your self, and don't rush it. You will know your machine better than any operator when you finish.
If you're going to work on mobile or industrial hydraulic's do yourself a favour and get the full set of Mac offset angle wrenches.
Without them it's the struggle is real to impossible.
Love the channel and the projects you tackle amaze me.
Absolutely Buy yourself a crimper. A friend of mine finally bought himself a cheap crimper and has said he wishes he'd bought himself 1 when he first got his machine. He's got himself out of a hole a few times by having one. His even re-used a used pre crimped end by cutting off the crimp and tigging on a new piece of tube then re-crimping it as a temporary fix (2 years ago😂) their totally worth getting especially if you've already got a hydraulic press. Look around they sell pretty cheap ones as your not looking to make hydraulic pipes as a business
@PacificNorthwestHillbilly Matt, when I replaced most of the hydraulic lines on my machine, I picked up a line crimper at and auction for like $50. The dies were under $125 each. Spent about $600 all said and done... highly recommend!
Keep up the great work man. Love the way you clean and paint stuff you fixed.
If you are at all concerned about the wiring, go with your gut and replace it. Especially in a spot underneath the engine where oil/debris naturally builds up the LAST thing you need is suspect wiring. I had a tractor catch fire underneath the cab caused by an electrical short. Incredibly difficult to get to to replace the harness, but even more difficult to get to to extinguish the fire.
Zep purple degreaser from Home Depot in a 5 gallon container with a weed sprayer is the best way I’ve found to degrease large areas like that. I would run those hoses. Replace the ones that are swollen or obvious leaking. Your going to spend some money on having to make those hoses. Orilleys auto parts sells their brake parts cleaner at a case price as well. It’s way cheaper in the case than by the can. Give Charlie dog some love for me. I can’t wait to see the next episode of the Matt and Charlie fixit up show!!!
Nice bit of CAD work 😂. Glad you invested in the big wrenches, makes life so much easier👍. You said it’s a big project but take inspiration from you dozer, it’s amazing, such a good job and the excavator could be too. Not sure about hydraulics in your part of the world but round here (UK) there are smaller businesses that look after the farmers, if you are not in a rush they do good rates maybe you can get a bulk discount 😂😂. Keep the faith, you will triumph 😀👋🇬🇧
Use a roto hammer on the tight fittings,works amazing. . You got some serious patientce to deal with this old iron.
Hydraulic hoses and fittings is probably going to be your biggest expense, it is so expensive for this stuff today especially if you go to a big brand place like Parker. But there may be a cheaper way if you can find a local repair business, such as a heavy equipment repair shop or a forklift repair shop or anything Ag, you may find one that will do some work for you at a much cheaper cost. I used to use a local heavy equipment repair shop for my hydraulic needs at half the price of a Parker type place.
double up the zip ties on each fitting instead of just one tie and that will give you 12.
I got tired of paying for replacement hydraulic hose, so I purchased a 100' roll of hose, and field replaceable fittings. This has saved me a lot of money. Might work for you
For your ziptie color problem just start using multiple ties to make color combinations like automotive wiring. 36 different color combinations with two ties.
I've certainly done that. But now I've switched to colored twist ties (like on your bread bags). They are available in so many colors and patterns now... lengths too. You can re-use them if you just need to make a quick change and they are SOOOO much cheaper to acquire.
good idea
Yeah, all those spray can degreasers have different instructions. Most say to spray a warm/hot engine, let set, then hose/pressure wash. I am not one to read instructions (you know real men don’t need instructions or manuals), hahaha..! Then a friend enlightened me. Another friend enlightened me on using the proper tool(s), I see you discovered it on your own with those new proper sized wrenches. It really does make a job easier, and you are young enough, you will most likely be using them again.
Great video series,
Thank you sir.
Zep degreaser works the best on build grease
you need to buy and use pipe blanks! made me cringe all those open hoses- great videos - very enjoyable to sit and watch others work :)
you should give a try to "over cleaner", i like the Easy Off yellow can... so strong and all the parts come brand new... lot more effective than any degreaser and cheaper! i really enjoy your series!
whitewall cleaner works well for what your doing.A 5 gal. pale is cheaper in the long run.If you have trouble finding it ask your local car wash where they get it.
you are gonna pull the engine...i've seen enough of your work (what about 100 hours or more now) to know you want the wiring done right and want the machine to work perfect...now is the time
pulling the engine also gets you a better look many other things...yeah it sucks, but it's worth it in the end
You do Great projects. You can do this!!!!! I look forward to this project AS WELL!!!!!!
Made in China ? Is it metric too 😳😉
I have to hand it to you Matt, You take on some mighty big jobs and work your way through them one step at a time.
I've been watching this channel since the purchase of the Dozer. It is always good to watch.
You are so thorough and you think everything through way in advance. Thank you for spending the time to put the videos together for us.
my brother inlaw is a diesel mechanic he uses Super Clean degreaser and he said try a Rotating turbo nozzle on pressure washer... pull engine now get it done.... good job!
Great video, Matt!
For anyone looking for wrenches and socket sets , check out yard sales and auctions. I find them regularly because when someone passes away most people have wrenches or have no use for them. I once got a beautiful set of wrenches with Royal Air Force inscribed on them (with an inscriber machine, so not worth much) … I like to think a aircraft maintenance mechanic immigrated to Toronto (where I am) after WW II and worked on the AVRO Arrow (and on to NASA) project or DeHavilland Aircraft.
P.s. the Degreaser in large jugs that Home Depot sells is pretty good.
5 gallon bucket of super clean and a 1 gallon garden sprayer will do wonders!
Damn brother… every day I’ve been checking your channel to see if any new videos posted! You made my day today!
Dude, light is a Godsend but if you were down here (12° N latitude) you'd be eaten alive! Glad you don't have the bug problem, makes outdoor work so much more enjoyable =)
You should get a set of nice 1/8" split point drill bits to make a pilot hole for the stepper. You don't "NEED" a pilot hole for a stepper, but it sure does make things go faster. #30 bit is common for 1/8" rivets and are cheap and easy to come by in bulk.
Matt, get yourself some Super Clean. Works better than degreaser.
Use an air chisel on those hydraulic fittings to knock them loose, use a blunt chisel
I know someone may have said this already but get an air hammer or a battery powered one, put a flat faced tool on and give a few braap's to the stuck nut hydraulic fitting and it pop's open. Guy called Captain Kleeman here on YT is fixin an old Ford backhoe and he has had luck with that method.
That tracking issue may also be because the other side's track drive motor is going out. You can get those as rebuilt units and sealkits also. Dirt Perfect had that issue on his 120 that is in JD colors.
If you gonna pull the engine you might as well fix or at least check the wiring since you have access to it. Least it would greatly reduce the change of a fire and electrical issues later on.
Some people have used surpluscenter for their hydraulic needs. Others have made a deal with a local shop for larger quantity of hoses. If you are planning to replace all the hoses that crimper could saveyou some money plus you do have other machines with hydraulics...
Also if you want more things to do. You could always think about changing bushings and/or line boring the boom and bucket and changing worn out pins. There are company's that do that and if remember correctly Dirt Perfect has a video where he does that to his JD 120.
But yeah great video. Keep doing your stuff.
You can buy a cheap crimp tool for a few hundred dollars and also the ferrules for the fittings. Then buy your hose in bulk reels. It will be a lot cheaper than having a hydraulic shop make up those lines. Especially handy when you have fittings that have to be "clocked" a certain direction to each other. It will pay for itself over time just in not having to take a leaking hose into town to get if fixed while your machine sits idle.
JIC hydraulic fittings only need to be firm to seal, not super tight. BSP also only need to be firm, but they tend to be over-tightened and they deform and then need to always be over-tightened to seal. That’s why they’re not as good as JIC. O’ring fittings are excellent and also don’t need to be super tight, but losing or dropping the O’ring is always an issue, plus you never seem to have the right sized one to replace the split or worn one you have just removed!
I absolutely love your content. The best of luck with this project. I’ll be cheering for you.
Looks like you live on a tree farm. (hillbilly type), gr8 progress, lots of work ahead. Best of luck:)
Super Clean is the only degreaser you need
Use a air chisel to brake the fittings loss . Use a blunt punch in it. So simple
Take a air hammer and beat on any fitting you need to take off and it'll come right off
Tech tip, Oven cleaner works great as a Degreaser and Coffee filters make a great lint free rag.
You have the patience of a rock. 👍👍
Just a tip for those stuck hydraulic fittings, use an air hammer with blunt end or I’ve seen someone use an SDS drill with cut off bit. Seems to do the job loosening the rust.
Another master class in rebuilding - your doing a great job -
I like the Pride zipties! :D
I really want to buy a crimper. Hoses really started to catch up with me. I ended up just leaving my machines sitting. I try to replace all my wireing. Make it so nice to have a turn key machine at the end. Excited for more of your videos!
15:19 Ha ha, yup, it is
I didn't own a diesel heated pressure washer, so I bought a Chinese instant water heater off of Ebay (around $200), hooked it up to a propane tank and connected it to my electric pressure washer and BOOM "Steam Cleaner".
