Kevin Thank you for taking the time to share your method of rebuiding a hydraulic cylinder. Your video is very helpful. I am also glad that you can ignore the negative comments from the couch potatoes that admonished you to hire a professional. They couldn't find their way around a tool box, and they are just jealous of people like you who fix worn out things on a regular basis. Capt. Art
I own a company with equipment that has many, many hydraulic cylinders,l. sometimes you can't wait to bring it to a professional shop and it's faster and easier to fix in-house.These videos help us do just that.Thanks for the video
I'm a certified fluid mechanic and I approve this video. Simple is best and this video hits the mark. (A hint to remember the o-ring orientation - the 'flat' ring is the back up ring to the rubber o-ring so it can't get extruded from its groove.. So...the o-ring always goes between the pressurized fluid and its back up ring...
Kevin, I very much appreciate your “how to rebuild a hydraulic cylinder” videos. Yesterday morning I watched the first video. With a much greater degree of confidence, I went out to my shop and began tearing down two 3.5” x 8” cylinders on an Artsway sugar beet defoliator. I struggled with the same o-ring you did, but after warming them up for a while they finally snapped into place. I had to use the washer and nut to get the piston on the shaft, and I mentally said, “Thank you Kevin! For that bit of wisdom.” This morning I reattached the hydraulic hoses, crossed my fingers, and pushed the hydraulic lever. The machine rose up with No hydraulic oil leaks, and stayed there! At lunch, I found your second more recent video, and have now ordered the additional recommended tools from Amazon. I was able to order the seal kits from Artsway through my John Deere dealership. I took lots of pictures as I disassembled the first cylinder, but still tried to put one o-rings in backwards. More pictures next time! Thanks again for the time you have spent creating these videos. You, and thousands of other wonderful people like you, are what makes RUclips such a powerful information tool.
Professionals do it every day, but they are not superhuman doing things that intelligent others can’t do with a little education and the desire to save money. Very good video showing every step, thanks for publishing this video.
Thanks Kevin for taking the time to put together a great informative video. All the best to you, from Perth, Western Australia. ....For all you haters out there, ....your comments are a true reflection of yourself! ...think about it before making a comment, if you have nothing good to sat ...say nothing, ...you know who you are. ha!
Thanks Kevin!! Your video was very helpful. I just picked up two small cylinders that I had rebuilt about the same size as the one in this video and the bill was $540. I wish I would have seen this earlier, but now I feel that I have more confidence in trying a cylinder repair after seeing your video. I believe I can probably make a spanner wrench like the one that you made. Thanks again God Bless I really appreciate it.
Oh man i do wish you would have seen the video first, that is a lot of money you could have save yourself, take pictures along they way so you can remember where things go and good luck on future rebuilds.
Great tips, my buddy did one but we put the gland seal in backwards so we need to fix that and the tools will be a big help. Locally we take our cylinder apart and take it to Hydraulic Supplee in Orlando FL. They get the seals in a day. Our cylinder's are used in a boat lift and there are no numbers to be found.
Thank you for this demonstration. You are a good teacher. Don't worry about the experts. There is at least one that always chimes in with their vast knowledge.
Awesome video Kevin! Thanks! I have the same cylinders that needs to be rebuilt. I didn’t want to spend the money or time sending it in to a shop. In am now confident I can handle this project!
Thanks Kevin, nice job explaining all this...will make things much easier for me. I recently took a similar size cylinder to a shop for simple rebuild, no machining or difficulties and they charged $240 cash/$270 credit card. I have another one leaking and doing this one my self, kit was $43. Again, you are much appreciated!
Thanks Very Much for the Video,I found it very helpful and informative,I’ll going to do my Cat Skidsteer 4 in 1 bucket Hydrulic cylinders now! Cheers Mate
Kevin is really good at repairing things and always does his best to show people how easy it is to do it yourself,like he said if you want to pay someone to do it for you go ahead but don't down someone for trying ,,he has saved us so much money over the years being able to diy.Good job Kevin
@@Robinson-Homestead I just resealed a boss plow cylinder (very small piston) with no seal tool and it was a total pain in the ass. Your video helped give me the confidence to give it a try. I had problems with the new piston seal stretching after putting it on. Maybe I should have warmed it up first? The stretch made it difficult to get the rod back into the cylinder. I had to push the seal into the groove with a flathead screwdriver during insertion.
G'day, i am a mechanic and have trained in hydraulics and the only suggestion I have is that to save one step the end od the rod that connects to your machine can be left in situ and may make it easier to undo and re tighten your piston nut. Apart from that you basically have done it the correct way. I have re sealed a number of rans myself and gave owned a number of earthmoving equipment aswell as repaired othes machines. Tgank you.
I rebuild alot of hydraulic cylinders, I enjoy it, I've got a machine shop,that helps, lol, I charge 50 bucks +seal kit it's not at all hard,great video man, keep'um coming.
Kevin, I'm rebuilding a 30 year old backhoe. Got the price to have the leaking cylinders replaced and after watching your 2 videos, I think I'm going to give it a shot. Nice explanation, clear video work, understandable instruction. I appreciate you posting them both. Thanks!
I've been in the industry for over 15 years, you did fine. If I am getting paid to repair a cylinder I take a few extra steps and make it like new, but that should work just fine.
@@Robinson-Homestead your welcome, since you replied I will tell you the extra steps. I would usually test for leaks (and test electronics) weld any leaks, hone the inside of the cylinder to remove any scratches, sand blast the gland and outside of the tube, make sure not to get any inside the tube, and repaint it. I work with electronic sensors and connectors for the cylinders so that's a whole different story but you did good. Only thing I would do different if you dont have electronics or care about the looks is hone the inside of the tube.
Great video Kevin. I have a cylinder that has started leaking on a backhoe and after seeing your video I feel like this is something I can do. Besides the closest shop is 50 miles away. Thanks!
Excellent video Kevin. I've wondered for awhile if rebuilding a cylinder was not just replacing some O-rings and seals. I can hardly wait to try this. Thanks for the lesson.
Great job - it’s a great help. even if we had the money there is not a skilled engineer in place that has repaired a cylinder. Having taken over 3 months to get the replacement seals I was nervous of doing the seal replacement myself but this video has skated my concerns. Many thanks
Very Helpful just did two Gannon cylinders about an hour a piece, got it done without the seal binder but it would have been a lot easier with it seals were totally shot definitely was time
very good step by step video kevin. i wish every one i watch was as informative as this one. i am now going to try to rebuild one of the lift cylinders on my skid steer myself. thanks
This is an excellent video, and I appreciate you uploading it. I have a Kubota with a bad steering seal, and now I know I can fix it if I can just get it out of the tractor.
Nicely done with lots of tips.. The only thing I would add is to spray down every component with brake cleaner as micro-grit it the number one enemy to pre-mature wear. The other thing to do is once the rod clevis is installed, spin the rod several revs to remove wrinkles and seat the O-rings. 👍✌
Ignore the haters. No need for a professional on this job, just some common sense and basic tools. These videos are exactly what youtube is for in my opinion.
Nice job! FYI, I never take the clevis off. You cant slide seals over it anyway and many are welded . It also gives one an advantage to pull apart a stubborn cylinder. Thanks!
I have in my hand, bought at Walmart, a "waterproof" pill bottle. In 1860 this would have been a MIRACLE, same with a hydraulic piston in the twelfth century. We take so much for granted now a days. Another helpful video. I see you got 35K subscribers !!!! :-D
I am trying to find out if my lift cylinders are the same as my bucket tilt cylinders. I replaced the tilt cylinder seals and I love the response of the tilt and now I'm want to reseal the lift cylinders . I'm trying to figure out if they are the same Seal kits for the lift and tilt cylinders. After 60 years my Massey tractor is due for new cylinder seals..
Did my apprenticeship in a small hydraulics shop and rebuild hundreds of cylinders like that, only things I would add is I would have put a bit of anti seize grease on the main gland on assembly might save yourself a lot of time in a few years
HI Kevin, this coming summer I may have to do this repair. Good tip using the warm water & that tool. First time I saw this tool being used. Full view & 👍 # 804 Wow Looks like you helped a lot of us. Thank you & stay safe, Joe Z
To find seals other than from the OEM is find local seal supplier. Take everything, the gland nut preferably removed and the piston to them plus whatever has a seal or o-ring on it. They will need to measure so as to match. Bobcat Australia wants nearly $200aud for the seal kit for a lift arm ram where as I paid $39aud for a seal supplier all matched plus the seal supplier is closer to me than bobcat. Whos not to say Bobcat don't buy the seals from the same manufacturer. For the hour it took to change even if they fail in the next few years big deal will change again. Thanks Kevin great video.
I think you should ignore the bitter negative comments. I really enjoyed the last video on Hydraulic Cylinder. I was wondering how you overcame the issue of that difficult seal inside the top component. Thanks for what you do
good info thanks for takeing the time to make vid. I have rebuilt many ag cylinders . Alot of people will not mess with them .. It is broke what you can go wrong roll the dice :)
Thanks Kevin, I'm hoping to rebuild the stick ram in my 89 JCB Backhoe. Its leaking badly. I think your video will be a good start. I do know that there are aftermarket kits for many pieces of equipment including mine. I think a shop would charge $500-$750 to rebuild this $750 if the "head" (the part you took off with your homemade wrench) is badly rusted and has to be replaced... Thanks again.
Hey Kevin, my first cylinder of course was the single boom cylinder on my 307 Cat and a bit of a monster. It took a come along to extract it just as an example of the task along with a small sledge. Leave the gland in just shy of the threads because you must keep it perfectly aligned. I had to have a machine shop break that 3-5/16" lock nut loose because I couldn't break it loose with a pipe wrench and 14' pipe. (they didn't even have a socket that big and used a huge pipe wrench and machine table and fork lift). Today I am faced with reinstalling it in the cylinder. Yikes. Btw I think the seal tool is less needed on the big cylinders. I used it but felt it was unnecessary. Yesterday I put everything back on the 3" shaft and I had to use the nut to press the gland back on while keeping it lined up. I'm sure I won't get it back in without compressing that main seal with tape and hose clamp. Wish me luck guys. Btw I made a nice gland wrench out of a BMW suspension part my son donated with a 6' handle. Worked great. Carved it out with a cheap HF grinder and cutting disk. Cat gets $350 for that sucker and the Proto spanner wrench I foolishly paid $130 for was a total joke but handy once it was broken loose. One more thing I must mention is be sure to shop around for seal kits. I paid $75 (a US company) and I have seen it since ranging from $55 to $310 so beware. That Proto spanner starts around $55 but it wasn't until I had the Proto name and model # in my hand that I easily found ii for $55. I'm tempted to return it and repurchase it at half the price I paid. 😡
Let haters hate Your videos ARE GREAT. If I was a rich kid I would have it done for me of course but with prices of everything being so expensive I end up taking and fixing the best I can my own stuff. I bought a land without understanding fully the zones so any money I get I try to add it to the land so someday I can live on it . And i can not afford luxury I need solar and a well and road so THOSE HOUSE PRICING OF EXCAVATORS either live in one of them or buy old equipment with no luxury.
@@Robinson-Homestead quite welcome yeah the expenses are crazy and I don't think I can even do it they say the well that I have to drill is 300 ft that's probably why I got the land as I did without knowing
When you are bumping the piston onto the msin rod from the bottom, why not screw the fork piece back on to it's thread on the end of the rod then there is no danger of damaging the thread itself. Just a thought.
There are other types' for instance hook spanners, and adjustables with a hinge as someone noted below. And with a hole instead of a pin for fire or water hose, etc. Also face spanners with two pins at an angle usually. hinged like a nut cracker.
Thank you after watching this I’m going to try on my own to repair mine . Talked to a couple places near me that repair theses and they both acted like this was a lost art . I asked them to give me a best case scenario $ and a worst case . You would have thought I was asking for there social security number. I’m all for a business making money but like the guy in the video said at least put alight coat of oil on it .
@Robinson-Homestead I am so glad to have a teacher like you when I draw the systems. I really appreciate your work that you do and thank you for teaching me how to put them together when mine breaks
So when given a disconnected cylinder like this. You crack the top off with the spanner. Any pressure to worry about or everything is already safe to disassemble?
Hello sir I am from India... I am working on hydraulic cylinders manufacturing and rebuild it Can you please suggest a book for manufacturing hydraulic cylinders and standard size

@@Robinson-Homestead quite welcome yeah the expenses are crazy and I don't think I can even do it they say the well that I have to drill is 300 ft that's probably why I got the land as I did without knowing
Thanks dude. Yeah i don't have 500 bucks to pay the Shops to do something i can do myself
You can do it just take your time and take pictures.
Thanks for the comment and good luck.
When you are bumping the piston onto the msin rod from the bottom, why not screw the fork piece back on to it's thread on the end of the rod then there is no danger of damaging the thread itself. Just a thought.
Good info thanks
Thanks for the Video Keep em coming .
Wish I had seen this last week. Had 2 rebuilt, nothing to it, thanks

Don't listen to the naysayers. Keep rebuilding cylinders and you'll be very good at it. :-)

There are other types' for instance hook spanners, and adjustables with a hinge as someone noted below. And with a hole instead of a pin for fire or water hose, etc. Also face spanners with two pins at an angle usually. hinged like a nut cracker.
thanks for the info
Good demonstration. Thanks.
Thanks for watching Thomas.
Thank you after watching this I’m going to try on my own to repair mine . Talked to a couple places near me that repair theses and they both acted like this was a lost art . I asked them to give me a best case scenario $ and a worst case . You would have thought I was asking for there social security number. I’m all for a business making money but like the guy in the video said at least put alight coat of oil on it .
Lol take your time and take pictures you will get it my friend.
Thank you

So when given a disconnected cylinder like this. You crack the top off with the spanner. Any pressure to worry about or everything is already safe to disassemble?
Thanks for the info.
I’m asking cuz I was doing a Cylinder for the first time n had no one to help me 😂 not being a safety nerd
THANK YOU.
The tool is called "Gland Nut Wrench/Spanner". There is an adjustable one that can covers different cylinder sizes.
Thanks for the information Bader.
