Crimping and installing all new pilot hoses on an excavator - Hitachi EX120-2

[@robertneilitz4926]

This is the most amazing home video I have ever seen, what is not seen, is the studying and planning and the patience and perseverance you've endured at your will.

[@TYSuggested]

Love this series. I'm an excavator mechanic and there is no way I'd attempt this in my backyard! Hats off!

[@TheMadJoker87]

hey matt, former forklift mechanic here, we had the exact same crimper machine in our workshop, dont waste time trying to calibrate it, when you change dyes for a different size it will all go to waste. the way you use it is how you did it the first time... crimp the first hose to the chart size and turn the knob until the light turns on, a couple tenths over is perfectly fine, but never go under the chart size or the metal sleeve will split and/or crush the hose. as long as you do this it will work 99% of the time with no leaks ...also, the lube is for the tip of the hose to slide the fitting easier, not for the dyes, we just used the same hydraulic oil to lube them

[@janudholm]

What a job. You are the best and most structured mechanic I have ever seen on KZbin. Glad you made 100K. Fully deserved. The best Channel I have ever seen.

This is going to be BETTER than new with all your attention to detail and the protection you are adding! Superb!

[@AdelinoGambiarras]

I think making your own hydraulic hoses was the smartest idea and also labelling every hose it was time and money saved. I am enjoy this excavator rebuild process thanks for sharing the experience 👏 👏 👍 👍 Merry Christmas everyone 🤶 🎄 🎉

Mango Bango and I thought reinstalling the main rotor transmission and GE T58 turboshaft jet engine on a Sikorski HH52a Seaguard amphibious helo was a b#@ch. What Matt took on is way more complicated. We had Polaroid picts to refer to making it fairly easy to hook up the various types of hoses and wiring harnesses. Plus every connector and assembly were match print labeled or stamped to the various assemblies. Kudos to Matt for doing such a excellent job restoring his Dozer and excavator. I'd fly in any aircraft he decided to restore because I've absolutely no doubt he'd go the extra mile to educate himself on what he'd be doing and his work would easily pass API inspections.

Patience, perseverance and organization…The absolute necessities for this job 😮🤩👍🏻

[@benediktpaul157]

Hi, I really enjoy seeing you rebuild these projects entirely, piece by piece. Keep it up! I have done lots of hydraulic hoses at my current job with one of those handpump crimpers, and it keeps you fit 😅. Couple tips: If you have two 90° and they don't quite fit, you can put some vice grips on the ferrule and twist it, even after crimping. It's not perfect but works perfectly fine. Secondly, it is extremely hard to over-crimp the hoses in my experience. Doing it by hand, you can feel it getting exponentially harder quite a while before doing damage, and with an air pump, you will hear it slowing down massively. No need to worry too much about it! Thirdly, bigger hoses are harder to line up in the crimper, but generally easier to crimp since the metal is a lot easier to move than in the smaller ferrules. It will be interesting to see how long that crimper will last. The one we got at work doesn't look all that different and is over 10 years old and has probably done well over 10000 hoses, and only now you can see it getting tired.

[@wigf173]

"Try to keep the poop off there....ohhhhhhhh :(" This whole series is excellent, Matt. You should be proud of yourself!

[@Matthew-f1l3q]

Crimping the hoses gets your arms ready for torquing the bolts. The box on Charlies head gave me a good laugh. Safety first.

[@chipsatterly4902]

$1200...and YOU had to REWIRE it yourself to get it to work?? ????? Crazy stuff.

[@terryrogers1025]

Having a field service background my appreciation for what you are accomplishing and some of the conditions you are working under could never be overstated, you are doing an incredible job on the excavator. This a fantastic series of videos and your assemblies are just sweet looking. Looking forward to seeing this project come together for you. Thanks for the update, really enjoy watching

[@draco7891videos]

Matt, in order to test the accumulator, run the hydraulic pump with no parts moving, with a gauge on the output. If you have pressure, that's a good sign. If you have normal system pressure when a control is moving but it drops to zero when nothing is moving, the accumulator is bad. Hydraulic pumps don't create pressure, they create flow. Pressure comes from the resistance to flow, either from work being performed, resistance to being pushed down the lines, or from the pneumatic charge in the accumulator. If the diaphragm is bad or the pneumatic charge has leaked down, the accumulator will be solid oil and provide no resistance, and thus no pressure. Loving the series so far!

[@snappingbear]

How long do they last? That one looks original which means it's decades old. It might be worth it to replace it given how many others things he's replaced with brand new parts.

[@jefflary5457]

Can you imagine buying a machine that has had this kind of care and attention to detail. Matt, you could teach the industry a lot about how things should be done. Great work. JeffinMaine

[@michaelwalsh98]

Matt you are amazing, that looks like a pit of snakes, but you are getting them one by one. Well done, that is seriously excellent workmanship!!!

Matt, I'm very impressed with your ability to get all the wiring and hoses hooked back in the correct places. Nice work my friend.

[@qabsoloff3252]

Wow! Just Wow! The work you have done to this point is simply amazing. Just contemplating the complexity of a job like this leaves me in a cold sweat. I seriously agree with the other comments mentioning your extensive mechanical, organizational and planning skills. I probably could have taken the excavator apart....but getting it back together would have left me scratching my head. Wow, well done.

[@swallowinn4410]

Well done Matt. Taking the time to lable your hoses a big dividend. You have already saved a lot of time during install Now you have a list/ ref. Book. to make a replacement hose if you use the machine enough when put back into service. Good job protecting Charlie, glad the protection not needed.

[@magilla9792]

Wow Matt, that ex is going to be better than from the factory. That was a huge bite out of the elephant. You keep making them, I'll keep watching them. Tell Charlie hi for me.

I got mine last week from Temu for $600. The red button is a battery test switch. The blue chart at the back has the offset values. Matt, you can put the fitting on, turn it upside down, hold it by the hose close to the fitting and bump it on a block of wood to seat the fitting. Great job Matt, keep hammering away at it. I just ordered a foot control for mine too. I haven't used it yet.

[@finjonz]

You are very talented Matt, you always find a way to do things and take no short cuts. I'm a Heavy duty plant fitter myself I love my tracked gear I get to work on a lot of big mining stuff and I don't know why but I get a lot of satisfaction watching your channel. I started way back when you first recovered the D4 and haven't missed a eps. The Hitachi build is going great by the way, I can't wait to see it fire up.

[@phatcowboy76]

In the Aluminum plant i worked at about 10 years we had a hydraulic shop with shelves with all the fittings. We had a table with a chop saw and on the bottom shelf of the table a hydraulic pump. There was a big old die crimping part bolted to the table which did the crimping. I've never seen a hand crank pump for this kind of thing. But you have your own portable crimper now. I'm an electrician but occasionally we wanted a hose that wouldn't be damaged as easily as flex conduit was so a 5000 psi hydraulic hose came in handy so we learned to crimp our own hoses. Nice video Matt.

[@HOWEARTDOTNET]

Thanks for making that video - this DIY hydro-hose thing is quite a conundrum for many guys not happy about paying the normal Napa hose rate and never finding direct solutions. At least I never have. Kudos Sir NW Hillbilly.

[@laughton57]

Another fun and interesting video. After watching you pump the crimper by hand I thought: There must be a better way! I didn't know what - but certainly a pump. Well, you found a way. Good job! Next year the ENERPAC manufacturer will have an integrated air pump. I'm sure they'll see your video - maybe already have.

[@TomYoureDoingItWrong]

One of your best videos yet, Matt. I have often wondered why more KZbinrs don't invest in a hose crimper, all the while they are lamenting the price of new hoses. Seems like ten or fifteen new hoses and the investment pays for itself. I haven't played with hydraulics since I fixed F-15s for a living in the Air Force, but watching this makes me want to jump in again. I bought an old non-operable Toyota forklift for $215 over the summer from the Bidadoo auction up here in Kent, Washington, and I don't doubt it will require some hydraulic work. I am thinking a crimper will be a cool new toy to have. One could have a decent side business making and selling hoses it seems. Have a great holiday!!

[@turnerg]

If you ever do a hydraulic system again i would recommend using small metal tags and stamp them for the line identification, that way you wouldnt need to worry about fading colors. Enjoying the series Matt!

23:55 We used to call it "CLOCKING" .. make sure to CLOCK your fittings before crimping the second one. There are of course swivel crimp or thread on fittings available. They cost more though, and make the hose longer

[@Brian-wy7ts]

Could use a normal torque wrench with a crows foot wrench for the hose fittings, if you keep the crows foot at 90 degrees to the torque wrench handle you can still use the specified torque value for the fitting, any other angle needs an adjustment to allow for the altered leverage. You are doing a great job restoring this machine
