For the piston seal that is a real pain to install, what I do is put it in a pot of water flat side down, seal side up, turn heat up until the water boils, then install it. Takes me about 10 to 15 seconds. The heat makes the seal more payable for install, and heating this way will not damage seal as a heat gun can destroy it with blistering.

Years ago (late 60's early 70's) when I worked at a Harvester dealership we used fine (400 and 600 grit) emery paper or crocus cloth not sand paper (a different animal) for cleaning scuffs from shafts. As a teacher I learned how important correct terminology was when instructing.

Thank you sir I’m a maintenance man who tries to do almost everything for our plant. Just did my first cylinder in a crown fork lift with the help of your vid here. The shaft seal is a real mother but what I found most helpful was two real small pairs of vice grips set just snug enough to hold one side in the grove while forcing it down. Very helpful vid thanks for posting

[@aligarizamarnel3424]

Hello! Quick question where did you got the seals. Thank you

[@idadho]

The heavy roundpart that screws into the end of the cylinder tube is called the gland. The piece at the end of the rod is called the piston. Usually, the nut that holds the piston onto the rod is secured with Loctite 569 thread locker for hydraulics.

[@Robinson-Homestead]

Thank you for the information.

[@dianacudby7290]

Good explanation, very detailed. One observation I have is invest in a seal tool kit. You will never struggle with those internal seals again. They are a real timesaver and you wont risk damaging the seal. Do a search hydraulic cylinder seal tool kit. Keep those videos coming !

[@kiethwashburn8442]

Thanks for the video, I picked up quite a bit of information and I thought you did a good job of teaching a practical way of keeping things in order. There were a couple of other comments from some builders who must do this all the time, so I appreciate those comments as well. One thing I wanted to point out was using some harsh cleaners with no protective gloves. I have done this for years but I am now at a point where those harsh cleaners ie. lacquerer thinners etc will make me feel pretty lousy for a day or two afterwards. An industrial hygienist told us that if we wash parts in gasoline with our hands, within three minutes it will be in particles coming out of our breath. I watch it pretty carefully now and avoid the down time. I hope this helps some of your followers, who like me , may have been a little bullheaded about some of this. Again, great job and thank you for the video. I know it must be a hassle to work with the camera and oily hands, getting it turned on and off, but I do appreciate the lesson.

[@chucklynch8397]

Excellent video! the best I've seen on Cylinder repacking. A couple of helpful comments for your viewers. Some folks may not be as handy as you are so they can find the tool you made from various sources. The tool is a Spanner Wrench and many are adjustable to fit different size cylinders. Your cylinder looks like a Case. Other manufacturers use different types of connections instead of holes. JD typically uses slots. Also, the end of the cylinder may be called a Rod Guide or a Gland Nut. Some of them have small set screws in the side of the cylinder that must be removed first. The replacement rings for some manufacturers are very expensive. Repacking rings for two JD lift cylinders on a backhoe can run about $250-$300. You can find good repacking rings significantly cheaper from various distributors or from hydraulic shops.

[@BDBee81]

Thanks Chuck for a wealth of information...

[@johnoriel4241]

Even when I have a proper spanner wrench, I've found that the pin tends to pop out of the holes on the gland nut if you put a lot of torque on it. If that happens too many times, the hole gets buggered up and makes matters worse. I solved that problem by holding the handle with just enough force to keep the wrench in place and tapping the wrench at an angle over the pin so it puts torque on the wrench and also drives the pin into the hole. It's surprising how repeated light tapping will break loose a nut you couldn't budge with brute force.

[@danabbott2398]

In installing the main seal push the seal in so it holds in the groove. Take a dull smooth tool and buckle the uninstalled portion of the seal inward. This will shrink the diameter of the seal the you can pop it in place. Don't worry about pushing the seal to the corner the hydraulic pressure will do that. Also you installed the outer dirt wiper backwards. 16:18. The lip goes to the outside to wipe off dust and dirt. With the seal facing inward dust will enter around the rod etching the chrome causing a future leak. I worked on Case Construction equipment and have done hundreds over the years. Use Loctite 243 (oil resistant) on the threads if you don't replace the self locking nut. Loctite 242 is not oil resistant.

The chromed shafts vary depending on their diameter as to how thick the chrome layer is. The chrome is very hard but the shafts are quite a bit softer and will bend before they break.

[@Robinson-Homestead]

[@andrewstoll4548]

You dont have any use for it yet........

[@wxfield]

I think that larger internal ring you were struggling with is called the "rod-seal" ring. We boil or heat ours slightly to make them more pliable. Once they are softened up, they go in super-easy. You can actually do damage to the rod seal forcing it in cold.

[@doorguner01]

wxfield yep

[@1003freak]

Question? Which way does the seal go in Flat out? Towards the outside of the cap and grooved side in?

[@davidcruz-ku2zb]

good to know ; thanks

[@nidalaussiepies8367]

Makes sence.

[@rrc7t3]

@@1003freak Yes, the grooved side is usually a V or U shape, people often refer to them as U lip seals. The pressure goes inside this groove & forces the inner & outer sealing surfaces onto the rod and out towards the back of the seal groove. Sometimes you might have an O ring or a Quad ring pushed into this U or V lip on the seal, this is known as an energized seal. It just puts a preload onto the sealing parts of the seal.

[@SINSTL]

Literally everyone wears socks with holes. But I get your point.

[@cbmech2563]

The 2nd ring on cylinder head is a backing ring and goes away from the hydraulic pressure . (To keep the oring from getting cut ) the second ring inside is a polypack v-ring . Do NOT Use a screwdriver , use piece of 1/2 inch rod with the end smoothed (I weld a nut on the back end to have something to push on) . I work on trash trucks and have worked in shops where I rebuilt 4 &5 a week . On the piston outer 2 are wear guides . The middle one is the seal. The white is the seal and and the black is the expansion ring . For the seal and the polypack on the rod drop them in boiling water for a minute , they'll go on a lot easier . You need to compress the white (piston) ring , I use a hose clamp . To get the head back on the rod a socket and a hammer works well . When reusing a nylock nut a little locktight helps .

[@cbmech2563]

Also make sure that the rod rings are the right direction . The polypack keeps oil in and the outer keeps dirt out , so the lips need to face the correct direction .

[@Robinson-Homestead]

Thanks for the info.

[@cbmech2563]

Your welcome . I started rebuilding cylinders as an apprentice operating engineer heavy equipment mechanic and have probably rebuilt several hundred since then (most on trash trucks). When I started most rod packing was multi v stack fabric , the polypack is a hell of an improvement .

We did have to know how to operate them, once we had them fixed/repaired, & I for one enjoyed putting the equipment through its paces, to test out our repair work, ... lol, ... had to work properly, 1st time, everytime, ... and doing it the same way (repeatedly), always had the same result, ... you either did it right, or it was wrong, ... no other outcome, ...

Thanks for watching.

Thanks Mr you give us every detail of this job 👍

[@williammcguire3rd]

Good job! Looking for function not fashion.

[@Robinson-Homestead]

That's right.

Great video but you put the Wiper seal in upside down, that's why you were struggling with it. The thin wiping lip faces outwards. This would also be the reason for the Head bush not going back over the rod easily as the wiping lip would be pointing down below the groove where there is no clearance. You might have found a bit of the seal left at the base of the rod end. With this type & size of Cylinder I would expect to fit the Head bush back over the rod by hand, maybe little tap with a dead blow hammer might be needed. When assembled, you should be able to turn the rod with one hand, if it's much tighter then generally there's a problem. One tip for people who might be resealing Cylinders that somebody else might have tried to do previously is lookout for marks from screwdrivers etc. in the rod seal groove. They can be hard to spot but I've resealed lots of Cyls. that have been resealed by somebody else but are still weeping past the rod seal. These can be polished out in a lathe or make a sanding disc to fit into your drill. A Dentists type mirror, the little round ones on the end of a rod, are ideal for checking seal grooves. Hope this helps somebody, Rich.

Thanks😊

Great video but where do you get thr rebuld kits from? Thanks

[@gadsdenviper7149]

Yep, I was talking to him while the video was play, hey turn that seal over the lip goes out.

[@learndiesel528]

@Daniel 045 Try finding a fluid power book by Parker Hydraulics or John Deere intro to hydraulics books. They will do you justice.

[@luischacon6211]

rrc7t3 how do you know what seal kit to buy ? If you have a cylinder unmarked or old ,

[@ericisawesome5725]

"It doesn't have to be pretty, it just has to work" Best advice ever! Thanks

[@Robinson-Homestead]

Thanks for the comment Eric.

[@TheDiscoPaul]

Great video. Gonna try and rebuild one tomorrow. THANKS

[@Sluggo01]

I use plastic tools to reinsert all gasket/rubbers, less likely to disparage the rubber or put gouges on them..don’t use sharp steel screwdrivers, one little nick and high pressure finds the least resistance!!!!! Merry Christmas

[@Robinson-Homestead]

thanks for the comment.

[@davewright3088]

I use bamboo chopsticks as removal tools for O-Rings and seals. Pretty tough, and you can sharpen or carve the ends to get into the grooves and clean out the gunk. Won't scratch no matter how pissed off you get..!

[@albertojaime7821]

Where did you buy the seal kit?

[@enriquealvarezcastrejon5291]

Thanks Kevin very thorough and to the point.

[@Robinson-Homestead]

Thank you.

[@clivestamp1891]

Many thanks for videoing this. It’s a great service to us who have never done this before and in the middle of no where.

[@Robinson-Homestead]

Thanks for the comment and watching Cllive glad to help.

[@rocksandoil2241]

I've had 6' cylinder where the rod bent. You have to replace the rod and packings as well. Sucks cost wise but cheaper than a new whole cylinder

[@Robinson-Homestead]

Thanks for the comment and watching

@@Robinson-Homestead Do you have rebuild kiits for a 2 1/2 ton Ausco floor jack? I do not know how you respond to me about this questions.

[@chadfinley899]

Good job man, but it'd be nice to see you wearing nitrile gloves. I know a good mechanic that died from liver issues because he never wore them.

[@Robinson-Homestead]

Thanks for the info.

[@BDBee81]

Safety 1st is priority No.1 Had my share of countless hydraulic oil bathing adventures only then to learn Hydraulic oils enters skin pours rather effortlessly though our body has difficulty removing any. As I was told from memory it cannot..

[@BDBee81]

Kevin any chance you could pin Chad's post to the No.1 as this deserves it as much as everyone deserves the OHS tip.. Thanks

[@AlphaBobFloridaOverlord]

This was a huge help for me! Thank you!

[@Robinson-Homestead]

Glad I can help thanks for watching.
