Excavator Repair, Swivel Joint Rebuild, Yanmar Vio-50.

I know it's kind of random to say it, but I really appreciate the fact you clean machines and their parts when working on them. Others take great pride in rummaging through all that mess as if cleaning it would take away their manliness or professionalism.

[@gbentley8176]

Yep gets my goat. Two minutes to clean makes a job much easier especially when dealing with hydraulic cleanliness. Often shows other hidden issues too.

[@guy7gsa]

The cleaning is much appreciated

[@danhard8440]

ya its good when they clean the oil that is preventing it from rusting🤣😂

[@silicon.alchemist]

ya pretty much don't have any choice when working with hydraulics. A little bitty bit of dirt inside any of those parts and the whole system can be toast...

YT videos are head and shoulders above the super low level of teevee. This video was a perfect example. I told the cable company to stuff it in 2007 and never looked back. Now I have Netflix and Prime for movies, and I figure I've missed about one billion commercials by now by never watching TV or listening to broadcast radio any more.

[@Pest789]

I just want to say I really appreciate you putting yourself through going under that excavator and taking that swivel joint apart *with a camera in your face* for my benefit.

[@simonrival1613]

We used to tell tank operators in the army that they could only rotate the turret 7 full revolutions either way before it unscrewed itself or bottomed out. It was pretty funny when they would forget to keep count and come up to us asking us how to fix it.

[@jonka1]

From what you say I take it that there was no indicator in the cab to tell the operator how many revs were left in each direction? Seems like an obvious thing to provide.

I hope you folks like the video, and have an awesome weekend everybody! Next week's video is going to be a fun one. I've almost finished it and it will be on Patreon either today or tomorrow. Here's a short clarification on this video: kzbin.info/www/bejne/mpCogWyaltBpndk

[@TheNikitis]

I have the Vio 27-3, same year as yours. It's the same machine exactly except for I'm lacking the enclosed cab. (Open Cab). I'm running into the same problem as you. The dealer wouldn't fix it, but I know it's this piece as they checked the valves, and the cylinder and are fine. I want to Thank You whole heartedly as I'm new to these things and I know this is what is wrong with mine. I now know what to ask for in repairing mine and I had no clue before. I also want to ask, do you notice an improvement in your travel motors as well as a result of this fix? I'm losing power there as well as in my blade. One other difference is, I have a plastic gas tank, and have no gas issues. Verified after your other video. For all of your caps, you used, what size hydrolic caps did you use while doing the project? Also KEEP DOING THESE! Every one of these videos helps me in fixing mine up as well as mechanically they are identical!

[@TheNikitis]

Also I upgraded the Lights on mine to LED's. HUGE improvement. I recommend the Sylvania 3" LED Light 2N1SP, part number 11920293 F1 for the boom light replacement, fits perfectly, and the Sylvania Lightbar 2N1SPBX Part number 12018818 F1. Both of these were replacement bolt-ons for mine, the light bar for the top may or not fit yours, but the boom light certainly will. I'd need to see your front top light to see if it has the same mounting bracket. They have 2 light modes, wide, and narrow on both. To use both modes you'll need a SPDT switch to switch between the modes, I can send you wiring diagrams for them and you can make a new video on it. Night time working is fun on the excavator.

[@lemmywinx]

Oh Man, I've done this exact same job on my Volvo EC27 - boy oh boy they don't give you any room to get at those swivel joints. Took me days! On my machine they have a little peg at the top of the joint which interfaces with a slot to allow it to swivel with the cab. The pin on mine had worn slightly, which meant when the cab rotated the swivel lagged behind slightly (as the pin had some slop in the slot). This meant that it would pull / push on some of the connected hoses, which caused them to loosen and leak over time. I thought this was worth mentioning.

[@SamStolpe]

Do the dumptruck and the excavator have names yet?

[@FarmCraft101]

@@TheNikitis No difference in my travel motors, but if those seals had been leaking then that would be the expected behavior, so it may fix yours. My caps were 3/8 BSP and 1/4 BSP, mostly 3/8. Thanks for the tip on the light, I'll check that out. Cheers.

[@copperclockmaker]

I figured they had something like that in there. I used to be a tank mechanic on the Abrams. It has something similar called a "slip ring" that is mounted in the center of the turret under the main gun breech. It has fewer hydraulic ports on it, but also has electrical contacts to transmit power, data, and communications between the turret and the hull.

[@Rob89139]

One of the reasons I keep coming back is because you take the time to explain why you are doing what you do in these videos. I'm certain I'm not alone. Okay, back to the video

[@TheNikitis]

UPDATE! - Guy who has your similar excavator again. I just finally replaced my swivel joint seals. I got my blade working and holding again, and tracks tracking again! THANKS FOR THIS VIDEO! I finally worked up the gumption to take this on myself thanks to you, and now have a working excavator. Runs like new except have same issue with tracks not riding evenly as you do and pulls to the left. Very messy job! My seals were worse than your old ones because mine were MISSING!. They had disintegrated. Out of like 7 seals, only 2 where there and the rest destroyed, the rest no longer existed, amazingly it still functioned at like 20% power even with them missing. Enough to drive it onto a trailer. And my blade would go up, but not stay up. My swivel joint was exactly the same as yours, and same part number for seals. Anyway, I don't know how many people have your excavator, or similar models and could take this on, but I wanted you to know I did! Thanks for the help again, and looking forward to seeing your LED Light upgrades, you won't regret it. (Hint those sylvaine part numbers I sent you before have 2 modes each, so get 2 SPDT switches, and wire it the switch so you can switch between wide angle and focused angle.)

[@Wornout1]

Farmcraft101 is one of my favorite videos. John has a funny sense of humour and he makes me laugh. He gets himself into some tricky situations and eventually he fixes them all. I am older than 75 and will not get involved with big machinery but his solutions keeps me interested. Keep up the good work.

[@Locane256]

Wow, that was great. I watched every minute of it and I feel like I gained 10 years of hydraulics knowledge in about 45 minutes. The most ah-ha! moment for me was when you took us on a short tour of other equipment that all had similar looking hydraulic pieces in them - I'd been under the impression that hydraulics were bespoke and specific to the machine and had just never thought about how generic and similar it might actually be. I was thinking they were more like engines where there's so much variation in how they're done (small vs. big, 2 vs 4 stroke, # of cylinders, etc) that it was almost specialized knowledge per piece, but I get it now. This is one of your best videos IMO - thanks for making it!

[@TheNikitis]

The pumps themselves are a little more complex, but the rest of the system is just checks and valves, and pressure build up. If it leaks (due to those clumsy seals) you lose pressure and thus functionality of your device.

Hey there! I want to share an other trick with you. If you don’t want to run oil down your arm use a multi use rubber glove, not one of those super thin one time use gloves, and fold the rear side one time to outside. So you have a channel which catch the oil! Thanks for your awesome videos. Greetings from Germany

[@nerfinator03]

Since I've started working on dirty stuff with dishwashing gloves I had such a better experience doing stuff. Great grip, harder to cut and tear and multiple use for the nasty stuff. Extra points if you wash them by just washing your hands while you still have them on!

You are the first person that I have seen actually protecting the seals as you were putting them on the fittings!!!!!

[@williamburrows2755]

Real high pressure stuff. Great master tutorial - bet the local hydraulic shops are snarling.

[@GAMESHREDDER27]

At our shop we actually use old telephone wire because the wires are all different colours with stripes and you cut the wires in 2 pieces and tie them to the fittings. Works pretty good when you have to take the valve blocks out

[@Locane256]

30:50 Ahhhhhhh I get it now - I was completely mystified by how a swivel joint could possibly work, but after seeing the holes in the cylinder and your U-shape explanation, it makes perfect sense. You are right, it is a simple solution to what seems like a really complex problem.

[@martinruetzler2856]

Yes, seeing is understanding in a second. Thank you so much!

[@CGT80]

I was also unsure of how the swivel worked, but I operate equipment and repair and build many things. My guess was that it was laid out horizontally or radially. It makes sense that they built it vertical, so I was close.

[@glenpaul3606]

Great job rebuilding that swivel joint. You replaced all those seals as good as any professional. It's nice to see someone fix things themselves as good or sometimes better than had they hired a shop to do the job. Very gratifying I know because I'm the same way.

I literally am tearing my Bobcat 323 apart on Monday to rebuild the Rotary Manifold... couldn't ask for a better video today.

[@markbacker7862]

Maybe other people might agree with me. A swivel joint to me looks at least structurally very much like a distributor cap. A distributor cap is round, the spark plug wires wind their way around the engine & end up on top where they plug into their individual locations. A swivel joint is round, hydraulic lines wind their way through the engine compartment & end up on top where they connect to their assigned locations. Just like a distributor cap is vital to the operation of a vehicle, a swivel joint is vital to the operation of a piece of earth moving equipment. Great job again & thanks for taking the time to capture your work on video.

[@jazko]

Damn, I kid you not - probably a week ago I thought, how do they make the seal between the drive motors and the upper part, if it can rotate endlessly. Now I know. Thanks so much for taking the time to explain everything in technical details.

You were a little mistaken at the 42:30 mark, when you pointed at the Slew Motor and gearbox and said it was the Rotary Union.

[@gittesilberglarsen1262]

@7:50. An interesting observation is that the oilpressure scales with the piston area as this: force = pressure * area. So if the seal breaks in the piston, the area involved is no longer the area of the piston but merely the area of the rod. Now say the diameter ratio of these two is x2 well then the new pressure will be: force = new_pressure * area/4. Which amounts to 4 times the original pressure! So if your hoses suddenly ruptures it is likely a leaking seal. Like your videos.!

Growing up on a farm since 11, you tend to learn about a wide range of things mechanically, simply out of necessity. FF to working construction years later, and get deemed the company mechanic when things broke or simply needed maintenance. FYI... Replacing the hydraulic lines on a boom lift from the basket down the boom is quite possibly more of a PITA than the center swivel rebuild. That swivel never did look like fun. Great video!

You have much more patience than I. I have a vio55 so now I know how to remove the swivel thanks to you. I just reciently rebuilt the air swivel on my Grove RT65s and it was very difficult and heavy. First I had to remove the electrical swivel which had 34 pairs of wires which had to be labeled. The service manual said to remove the electrical swivel cover, seperate the paired wires and label, but they show only one pair of wires so imagine my suprise when I removed the cover. As it turns out I may not have needed to repair the air swivel because when it was reinstalled there was still an obvious air leak just adjacent to the swivel. It was an old air line with the leak it a difficult location to detect. Today I purchased an old dump truck similar to yours except it is a ford. It has issues also but watching your videos has encouraged me so I will tackle each problem one at a time. Keep up the good work and thanks for the tutorials.

[@denjhill]

Those coyotes remind me of when I was younger and worked on an Oregon sheep ranch. We would trail packs of 1000 sheep 50 miles cross country to summer grazing areas. Inevitably, the yotes would find us at night. Their howling usually meant we would find a dead doe in the morning. This was before the age of high intensity flash lights so it was impossible to find them at night. But during the day a .308 lead pill would take care of business. Now I'm old and still in a rural area and they still howl. My neighbor thinks it sounds romantic. ??

[@dpeagles]

There is definitely a reason why coyotes and wolves were almost wiped out Seems Americans have forgotten.

[@mattfleming86]

I think it sounds like "what am I going to find dead in the morning" The problem with coyotes is the litter size. WITHOUT some management the populations explode. Without coyotes, the deer population will explode (and subsequently be obliterated by disease) When the coyotes stay away from my livestock I have no problems. But enough bodies will change anyone's mind.

I am now much more educated on the subject 😊. And your editing and camera skills are superb! All in all, it was quite a video- educational and very humorous to boot! Thanks for sharing. I can’t wait for your next video.

A clean workplace /maschine is half the job 👍 im just in progress to rebuild my case cx 28 excavator and see the videos of @ farmcraft101 with big interest- lots of informative stuff! Thanks a lot

I felt your pain working in cramped quarters with oil dripping down your arm. When you walked to the field I thought you were screaming at the sky, but it was only coyotes.

This was a real treat to stumble upon. Your presentation, filming and voice make this work very well! I loved the education on hydraulics and how to test this problem. The funny thing about the timing of this is that I just told an engineer at work to look into this very thing of how excavators can turn round and round with hydraulics going through there in order to glean some ideas on how we can make something work for our project on a much smaller scale.

Man that was a fascinating look into your world and a few problems most of us would never come across let alone have to think through. One thing that does come through is the respect you've gained from me for this process. You've also shown that the necessary ingredients for tackling a job like this include perserverance, patience, ingenuity and stoicism to name but a few. I was as happy as larry when your job finally came together successfully. It also caused regret that I'm not likely to need to utilise this. Thank you for your time and efforts. PS. Those bloody coyotes would drive me mad. Do they ever keep you awake with their constant noise?

Man, I truely respect your courage. As I saw, it must have been a hell of a job to disconnect all the hydraulic lines, taking care that you don't mix them up and working on the square inch. Not a lot of people would have done the same, especially from the group that are not doing this kind of work on daily basis. As we in our country say: "I will lift my hat for you".

Awesome video!

A newbie to your channel. I must say as a novice to equipment repair, your video was very helpful and informative. Understanding hydraulic in 45 minutes!!! Thank you for taking the time to video that repair!! Great video!

i actually learned something from a youtube video and i wasn't annoyed the whole way through ... earned my subscription!
