Tell me about it. Just got my car back from the shop... thought the tranny had quit but no, it was one of the CV axles - clean break where it passed through a rubber guide bushing!
That's why you always use axle stands when going under a car. The entire weight of the car is being held aloft on the hydraulic jack by a small rubber O-ring in the bottom of the unit 🤣
Hey! I'm a seal design engineer, so seeing you show a seal catalog and size gland was very cool! All the information you had on sizing new replacement seals was great! I spend a lot of time in seal catalogues, so nice to see em show up here
It's because O rings are dirt cheap and Back up rings are pretty spendy comparatively. If you really need a non-standard back up ring most companies can make em for you, but it doesn't make sense to always stock them
Adam, I have dismantled hundreds of cylinders with similar problems, aluminium glands are frequently a problem due to corrosion and subsequent galling of the threads. Applying heat in my experience seldom helps, as you found You only have a few seconds to remove the gland before the expansion of the aluminium gland catches up and then exceeds the expansion of the steel cylinder and then the heat softens the aluminium and makes galling/seizing inevitable. My most successful removal technique was to support under the gland on a block of hardwood and vigorously hammer all around the thread area on the outside of the cylinder with a heavy brass or copper mallet prior to attempting to undo the gland. This breaks up corrosion and loosens any cold weld in the thread. If the thread starts to get tight when unscrewing apply more mallet.
@@tedsaylor6016 The short answer, NO. I had LN available and found it too difficult to confine to a small area for dismantling tasks. It was indispensable for assembly of interference fit parts. A big mallet beats the stuffing out of LN for dismantling. I always smothered the threads in Never Seize on Aluminium glands on re assembly.
Hey Adam, Heavy equipment Mechanic here. If you ever have a pin stick like that either torch the pin center out a bit or air gouge the center of the pin a bit and often times they come out. Once some of the center material is gone and the pin cools its final od shrinks and many times comes free a lot easier.
He said he's going to try his hydraulic press first. If that doesn't work, I suspect he will use his milling machine to mill out the broken stud, as he's done in many videos before. Torching could easily deform the eye shape.
@@kindabluejazz If you do what I'm talking about and use an arc gouge it really doesn't heat soak as much as you'd think but does give room for the pin to shrink down. This process is well known by seasoned equipment mechanics especially in extremely salty environments and has a very low probability of deforming the rod end bore due to heating.
@@brucemadden1626 I enjoy his videos too! It works amazingly well to fillet out/off material, you just really need to be cautious to not shower yourself in molten steel accidentally.
I love, absolutely love, these actual machining videos. This is the "secret behind the curtain" that most Americans are utterly unaware of. Shops like Booth Machine Shop by the thousands, in cities big and small, working every day to fix the mechanisms that keep America going.
Seeing you applying heat to a hydraulic system like that, reminded me of a cautionary tale from my early days in engineering here in the UK. Following the Falklands conflict, during which we lost Royal Navy vessels, an emergency safety ‘flyer’ was sent out to all UK manufacturers. This was with regards to the use of Viton seals and what happens to them if they suffer an extreme heat event, such as being in a fire. Unlike conventional seals which char, Viton actually liquifies and being a Fluoroelastomer, it can release Hydrogen Fluoride gas AND, if you get that liquified Viton material on your skin, there was no other treatment other than to amputate the affected area! Whilst I acknowledge that Viton wouldn’t normally be used in the hydraulics you are dealing with here, everyone be aware - if you are dealing with any such equipment and you suspect it might have been in a fire (or you are going to use heat yourself to effect disassembly), take all precautions.
Funny, I live in the States but I remember a similar warning and it would have been about the same time frame (early in my engineering career!). I always warn the new guys.
@@kevinstark6329 Yes, I suspect the alert went worldwide, following the presumably unfortunate experience of either Royal Navy fire control teams and engineers during the conflict, or workers in dockyards attempting repairs or salvage.

That reed vise is the heaviest duty vise ive ever seen. The handle to tighten it looks like 2 feet long. insane. To buy a vise that size today would be every bit of $1500
Thank you for the explanation on looking up the seals! I am the new guy in a caterpillar hydraulic shop and what you just showed was a much simpler way than i have been shown. We often have people carry in a gland or piston from something they are working on asking for seals. I have learned many things from you over the last few years. Keep up what you do!
There is skill in using a catalog. Nice to see you teaching this stuff. I've fired a bunch of new guys through my crash course on looking stuff up in catalogs and it's worth every bit of my time and the student's time!
We found that the best way to remove the aluminum glan was to lay the cylinder on an anvil and use a pneumatic hammer to rattle the tube against the glan to free the threads.
I just rebuilt eight tie rod type hydraulic cylinders. When I got the the 7th one, I found out it had a bent rod. I had to break down and turn out a new one. The guy that built all these cylinders retired and is out of business. Looks as if I'm going to start making them in home. With supply chain issues and the fact that a lot of guys are retiring, I find myself having to make more items in house. That's OK, that's what I do best. I enjoy your video when I get a chance to watch them.
Keep a steel bucket full of cold water, heat the barrel till the aluminum head expands then dump the whole thing in cold water, repeat 2-3 times then unscrew head. Bobcat cylinders, and Kubota cylinders are made the same design, standard seals American threads. If the pin type spaners don't move it right off put them back in the drawer and break out the pipe wrench, but only put one set of marks in the head! 37years in the same hydraulic shop
Got here 50 seconds after upload! This is the kind of machining I’m used to seeing Adam complete. The new stuff is good too. I’ll take either as long as the filming remains this good.
FYI, the ASTM/SAE standards for O-ring grooves max out at 5000 psi. If you very carefully choose your back up rings, and design your gaps to the absolute minimums and increase the o-ring crush, you can extend the pressures to well over double that number.

I've always had pretty good luck with getting the gland nuts to come off by using a little heat and break fluid as a lubricant on them. Laugh as you want but it works.
Thanks for your lecture! Very interesting. The stuck gland, would it perhaps get loosened if You tap the tube over the threads? Oxide and grime fill the treads and is pulverized by hitting outside the tube. I believe You to have more luck with this method than just heat! Regards PeO
I know its seems easy to you with like hundred years of experience , But its fun to watch your hands on knowledge of simple things like seals and how the "interact" , like what they seem to be and what they are :)
Assuming you go to all that trouble of finding seals because you had first checked with Mahindra for factory replacements? Now you machine things to fit, and the next guy that needs to work on this will try to use factory seals and they won't fit. So hopefully he has the same knowledge and resources that you do.
Wow, four actual machining videos in a row! Maybe new shop building and new tool acquisition time is leveling off and it's time to get back to the work that made me subscribe. Fingers crossed...
Thanks Abom, I enjoy this type of video. I know it may be unnecessary for some of your viewers but I have never worked with this so if I do want to attempt my own service at least I have some chance of not sounding completely useless at the hydraulics shop! I am in Australia so unfortunately can’t use suppliers suggested. Cheers Mark
FarmCraft 101 did the very same job see his videos, Mahindra's answer when asking about seal kits was to recommend buying a new cylinder, they are cheap, however generic seals are available from any seal supplier quite easily.
1-5/16 wrench through the left side of the spanner wrench, and boom you got where to put the cheater bar on, holding the wrench with wright hand and cheater with left until enough force lock em in place for you to apply necessary force with that last cylinder 5:43
I've conquered a few cylinder glands that were that tight before and just applied a steady lower heat to the gland itself for several minutes, then just let it cool down for an equal amount of time, and loosened them. The heat will soak away from the gland into the cylinder letting the gland contract while the cylinder expands.
Probably a dumb question, but if it's a Mahindra tractor, doesn't Mahindra sell a factory reseal kit for the cylinder, so you don't have to do all the measuring? Love your channel as always.
Probably so, but ordering your own via a distributor is probably much much cheaper. Not to mention the value of this video is the knowledge to find any seal you may ever need, no matter the use.
I have several old vises and anvils. That reed vise is nice. I have one just like that Im getting ready to restore. I have a pat. Date Dec 24, 1912 105 reed I use daily in the shop. They are bullet proof!

Adam, 4 anni fa hai riparato un cilindro idraulico molto simile SNS 217, e hai utilizzato un kit di strumenti Seal Twistor, perché questa volta hai preferito usare le dita con qualche difficoltà? Comunque molto interessanti i tuoi video, grazie
You need a pipe wrench, put some heat on it and spray water on the threaded side to shrink it fast. A trick I learned from an old timer at Chevrolet school
The two gland nuts that came apart are steel i bet. There is a special place in hell for engineers who design aluminum gland nuts. Bobcat does that to.
Given that aluminum expands much faster than steel, you just added to the problem by applying heat. A little shot of liquid nitrogen may have been the solution.
I'm interested in building a hydraulic ram for a project. Were do I start? Let say i need a ram that has 18 inches of travel and can lift 800 pounds. Any resource I can turn to for guidance. What I what to build is similar to your content in this video.
They often do, but as parts get aged they not that often stok them anymore. Sometimes quicker and cheaper going directly to some well known general seal manufacturer
If that was an alu gland in a steel barrel, would you have more luck freezing the gland instead of (or addition to) heating the barrel, because alu would shrink more than steel.
I know Adam is capable of machining anything to make a seal fit, but not everyone has that ability. Seems to me the right seals **must** exist somewhere. The mfg didn't make them up custom in their own factory. Maybe they're metric; maybe they're newer than that 2013 book. I'd have gone online and used 'modern' technology to search for the parts, maybe even contact the tractor manufacturer.
Very possible but what is done ... is done. What he should do is make some kind of permanent mark or engrave on the piston or somewhere on the cylinder that the piston has been modified because the next person that rebuilds that cylinder ... if it isn't Mr. Booth ... might just order factory parts only to find out they won't fit.
putting the cylinder in the freezer would shrink the gland about .0015"more than the steel tube. Unlikely this would have been a great help for a severely corroded thread. You could have melted the gland out and machined a new one for good video content.
I am glad you know what the heck you are talking about because I am lost completely lost. I have fixed CAT cylinders seals but CAT had seal kits at their parts dealers.
Last year I had to design a custom pneumatic cylinder. What I would have given to have a catalog like that. It was incredibly tedious to find the right seals and o-rings. I only need it with metric sizes.

You can tell you have spent a good part of your life working on hydraulic cylinders by the way you work through that book.
Only cylinders I get are the ones the hydraulic shop couldn’t get unscrewed so it blew my mind to see they are supposed to unscrew somewhat easily.
Very useful information Adam. Thanks.
Surely Mahindra, or a tractor repair vendor, has an all inclusive seal kit sitting on the shelf somewhere so you wouldn't have to machine the pistons.
