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.

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.

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.

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!

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.

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.

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.

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.

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.

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.

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!

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.

Fascinating repair video. Great job on the repair.

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

As someone who has worked with tractors and plant and repaired myself all my life, I found this video very interesting and enjoyable to watch. You made a mucky daunting job very clear for us all to see and should encourage people who have viewed to have a go themselves. Great filming too.

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

You've given one of the easiest to understand explanations of hydraulic control systems, and in particular swivel valves, that I've ever seen. Watched the whole video end-to-end. Good job. YipYipYip!

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.)

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. The actual Rotary Union was under the cover where you were describing the electrical Swivel Joint is. The giveaway was the hydraulic hoses leading into it. Your explanations of how systems work is excellent and much appreciated by people who may be mystified by some of these mechanical systems.

Another one, teflon tape in hydraulics is definitely common but Loctite 577 is preferable. When installing teflon tape to fittings never go over the last thread otherwise it will be cut on installation and pieces of teflon will go through the hydraulic system a cause issues such as block valves or filters

Your videos are a huge help to provide some understanding of to resolve potential issues.

the hardest part (other then the contortions to work inside the belly of the machine) is getting the new seals in. other then that its cake

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. ??

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.
