ehhh maybe 20. I just had a new blade put in my snapon screwdriver inherited from grandfather in law, it was worn down and rounded out to the point it looked like these seal tools. the snapon dealer estimated the screwdriver to be from sometime in the 50s
I mean yeah knowledge is freely available everywhere college is a formality at this point, I like it so far though but I'm just a first year at community college so maybe I won't soon.
Same, I briefly learned about these in college as well. They definitely didn't go into the small details like the seals. (We only touched on them for about 2 days. And mostly how they operated not the internals).
I work maintenance at a plant that manufactures hydraulic cylinders, we call the gland the "rod guide". Crazy how one part can have so many different names.
I took a hydraulics class in junior college supposed to be a 8 week course turned into a week course after i found out all we would be doing is building a can crusher out of junk around our house and buy a entire book to do only 4 chapters in it waste of time
My farher has a hard chrome shop, he strips the old chrome off, repairs the rod surface and rechromes back to within specs. Hard chrome is used to protect the rod from scaring from trash and particles to prevent leaks.
I fixed balers and trash compactors for 10 years professionally and never new the name of any of these parts. Thanks for teaching me lol. I was great at it but it was too much for too little money so I moved on but glad I finally learned lol.
10/10 for explanation. 5 points extra credit for explaining the proper orientation of the seals. Like that thus cylinder has no gland nut. I ran out of room for all the custom tools I made to tighten those damn things in confined areas where rookies failed to tighten all the way.
@@motoredbikemadness2061 Nope, that is the industry standard terminology for a polymer or elastomer lip that cleans the shaft of a hydraulic cylinder as it slides back into the housing. That's not the worst one though. A short section of pipe that is threaded on both ends is called a "nipple". I mean ffs basically all plumbing and electrical connections, except for welding and soldering, have a "male" and "female" half. And technically speaking when connected they are "mated", although that one isn't used often anymore (at least not for these types of things).
I use a forklift everyday at my job and I was curious on how a seal could hold back hundreds of psi of hydraulic fluid, thank you for the brief explanation.
Little bit of trivia, double acting cylinders move faster in the retract direction due to less volume from the rod on the piston, they move faster but have less hydraulic force than the extension side does. Fluid power is simple but everyone wants to treat it like rocket surgery, the leaks leak and the squeaks squeak just like the customer likes.
Wow, Driving and operating for about 17 years,v I've had mechanics try to explain hydraulics to me a few times over the years, never as clear as that. Thank you.
Ah I used to rebuild these pretty often when working maintenance. I always had a fascination with the inside of everything and you did a great job packing lots of info in such a short video!
That's probably one of the most educational minutes I've ever had on the internet. All I knew about hydraulics is how the pressure works and that hydraulic oil is stupid slick.
I repaired these for a long time, pick sets quite often hooked and sharp picks to use getting out old seals, don't leave scratches in the metal and no worries. If you put your new seals in boiling water theres a fair chance you won't use the pick to put them back in, makes them much more pliable. As an aside never put the barrel in a standard vice as you can warp it. O - rings occasionally have a backup on both sides if groove spacing requires. The gland is called a Head in Australia and the rod is commonly called the shaft, the holed end is called a clevis. Rotary oil seals can be used in lieu of a wiper as long as it has the wiping lip.
There is some useful bits in this one. Lol. I appreciate general knowledge over specifics on a micro scale .. like when you explain," this type of seal looks like this , does that, and goes here most always for these reasons...."
"Pressure from both ends" made me chuckle too easily. Thanks for you guys always coming out to the jobsite to fix the equipment we beat the absolute dogshit out of.
i love this type of videos , can u please keep posting more videos about forlifts mechanics and tricks , specialy hydrolic part , im a begainner forklift technician , specialised in Electric forklifts , thank u
Dude I love to watch a master at his craft. Please make as many of these videos with as much information as you possibly can before you die. The youth depend on you.
I build these all the time. From tiny to mega. Very informative video. 9 times out of 10 your problems ( leaks, low power, sluggish engagement, settling) are found here. The rest is bore condition and rod condition.
Thick music wire is great small tool making stock. It's hardenable, comes tempered to a pretty tough and bendable but you can aneal it and pound it into whatever shape, or just bend and grind depending on what you need. I have a ton of small handled tools from picks, drivers, carving tools, sculpting tools etc so having a big coil of rod that's a good diameter for that kinda stuff is sooo handy even if its a bit more hassle than buying straight sections of ground tool steel.
Killed it! I've been known to soak seals in hot water to make them more pliable to get them seated inside the gland nut. 👍 Edited due to me being a dumbass.
If for whatever reason you're struggling to get the piston out of the barrel you can use an air compressor to force air into the barrel and it will force the piston out, something i learned working construction, helping the mechanic repair the massive heavy machinery pistons when they would leak oil, just please make sure not to stand in the direction of the piston when you force the air into it.
15 year hydraulic tech You nailed it.. Make sure you get your o-rings and Polly seals in Viton material when possible. Less corrosive with biodegradable hydraulic fluids (when used) and higher heat/ pressure capabilities. A little less flexible than standard materials but wells worth it for longevity.
A good way to remember which way they open end on a seal goes is to know how it works. The oil inside of the seal applies pressure against the lips, forcing it against the surface it slides along and it's seating groove, preventing leaks.
Kick ass explanation brother! I'm a sparky, and totally dig this video, although I'll probably never use it, I've always wanted to know this! Thanks man!!
As an electrician who has to dabble in various other areas from time to time this was so nice the seal positions get me every time this helps, would you be able to do a video like this explaining the LP engines various components on the forkems? Thanks for the info.
@@NDC1115 well that makes sense then that that was where I was taking them. I’m back down south now running in the warm. I’ll come back that way when you guys throughly thaw out. I spent last winter in Minnesota and Iowa also for Deere and I learned my lesson. It’s too cold for me, my truck, my wife, and my sanity. 😂
Dang that's way more simple than the ones I work on. So many less wear rings and cup seals. I kinda envy you. The last one I rebuilt was a 400 ton shear cylinder where the center is a piston but doesn't move then a U shaped piston that moves then the barrel. It was confusing until I was told how it worked.
Also the wiper seal, a good analogy are the crank and cam oil seals in ur “car” engines. Like u said only seals dust. No pressure or load bearing. So now u know the crankcase in ur car, doesnt hold pressure. Fact:its the air is under slight vac normally to vent the gases and the oil is under vac sucking into the oil pump
Love cup seals ! Ordered up a cheep Amazon tool for installing them on smaller cylinders works amazing folds it up drop it in and unfold especially good for the packing on bobcat bucket cylinders

It’s refreshing to see genuinely knowledgeable people on CZcams.
Isn't it? Made me think-"wait, did i smoke somethin"?
Absolutely
Buddy, you need to do more of these. I’ve learned more about hydraulic cylinders than what I used to in college in a day!
I mean yeah knowledge is freely available everywhere college is a formality at this point, I like it so far though but I'm just a first year at community college so maybe I won't soon.
💯
I got an industrial certification and this one minute video probably explained more than an entire 40oage chapter on cylinders 🤣
Pick a real major next time
Same, I briefly learned about these in college as well. They definitely didn't go into the small details like the seals. (We only touched on them for about 2 days. And mostly how they operated not the internals).
I learned more useful information in this 60 second video then i did in 14 years of school
Definitely wouldn't argue this lol
Every time
Because you were smoking in the bathroom and drawing an eye.
Wow. You weren't paying attention then.
As someone who deigned hydraulic cylinders for living. You're spot on.
At the company I worked for we always called the "gland" the "head" instead.
I work maintenance at a plant that manufactures hydraulic cylinders, we call the gland the "rod guide". Crazy how one part can have so many different names.
Rod end and cap end
Hmmm
Rod, gland, head🤔
Now wheres my wife at. I have sumpin I want to discuss.
I thought it was the glans... oh wait, that's another type of rod end/head.
Had a full semester college course about hydraulics and pneumatics and learned less than in this short. Then again, I actually showed up for this.

@@FunkFPV definitely old school. A pot of hot oil? "Get back to work and stop asking stupid questions"

Man had enough time for a tool review at the end. Amazing 🎉
The backing ring enables the O ring to take a higher pressure without forcing the o ring down the gap between shaft and bore.
