Just wanted to say thanks for posting this video. I have the same tractor, same loader, and what you showed was a big help in rebuilding my right bucket cylinder. Everything on mine was very straightforward and the culprit of my leak was the seal behind the wiper on the gland...very obviously bad. One thing I wanted to add for anyone facing the same job: My Kubota dealer told me that unless the bucket is bleeding down (not holding pressure), and as long as that hard flat teflon seal isn't worn down flush with the piston, he recommended just leaving it alone. They very rarely see it worn to the point of needing replaced. But keep it in case you need it later. He also said if you do need to replace it, you can put the new seal in boiling water to expand it enough to get it over the threads (without the special tool), then put a big hose clamp around it to compress it down when you have it in place, and then put the whole thing in a freezer for a while to get it to contract back to normal size. I left my teflon seal alone as I only have 443 hours on a 2008 L3400 and the existing t-seal looked perfectly fine. Great video, thanks again for the detail. Big help.
josh claxton Mine is a 2008 L3400 with the LA463 loader, serial number on the loader is B3305. Apparently there are different seal kits based on serial number/when yours was made. My local dealer was a big help. The seal kit I ended up with was 7J266 63402. It appears identical to what was in the video.
josh claxton I don’t know where the split is with the loader serial number. I’m sure I paid a little more getting my seal kit locally but it was worth it to have them confirm the right part number. There’s a very similar kit that’s only one or two numbers off but it’s got different seals, so you need to confirm what version your loader gets. It sucks that Kubota doesn’t make it more clear
I wish I had found your video last year. I had 2 bucket cylinders leaking on my Kubota loader LA1153S. I was under the impression there was a lot more to reworking the cylinders than what your video shows. After spending almost $1k on 4 cylinders and fluid for a professional to rebuild them and they still leak!! Yep all 4 cylinders are leaking again. One cylinder has been in 3 times because it leaks after he is suppose to have fixed it. I'm ready to try it myself with the help of your tool list and video. Thank you so much for posting this and going into great detail. The video is wonderful and I'm confident I can rebuild my Kubota cylinders and stop purchasing fluid because one cylinder just sprays out when I put hay out. Thank you again.
Sometimes I’ll run across a video that’s so well done-camera, sound quality, presentation, that I just have to go ahead and subscribe. Very well done Kevin. Thank you.
Kevin; just wanted to say that you saved the day with your video. You’re absolutely right when you said you hope you don’t spend 10 bucks to save just one, but when you have all the tools you need, with the exception of the O ring press tool, why not give it a try. You were very thorough and to the point in the video with simplistic layman’s terminology. Once again, thanks. My BX lives on
Great job Kevin. I hope you have convinced others to give stuff a shot, video and pictures is a great tip! I started fixing stuff when I was younger cause I couldn't afford nice stuff so most of it broke a lot. Then I couldn't afford to pay someone most of the time to fix it, so I figured I couldn't break it any more, so I dove right in. Now decades later I can fix or ruin almost anything all by myself:)
If you look at 3:27 of the disassembly the split bushing is toward the nut side of the piston. In reassembly at 23:30 he puts the split bushing on the gland side of the piston. It certainly didn't seem to effect the operation of the bucket! Interesting to see the update after the accumulation of the hours to see if it cuts down on the life of the repair...the oem cylinder was rebuilt at 9xx hrs. I also must say that this is the best and most detailed video I have seen on cylinder repairs...that detail is the only reason I was able to make my observation.
Thank you, thank you, thank you! I just did this yesterday…without that seal tool. As I was soaking it in hot water and trying to fold it for 45 minutes with oil all over it my brain was conjuring that tool. I bought it just now because that was the 3rd time I’ve rebuilt that same cylinder in the last 15 years.
It did but after incredible effort and a more incredible mess. It was so much easier with the tool. However, like carrying an umbrella prevents rain, this cylinder is still leak free.
Oh my God! You showed what I really needed to see for removal and install. A special thanks for showing the links for the special tools for removal or installation and how to use them, what a lifesaver. Good Job!!!😀😀
Getting that nut broken loose to get that one o-ring is always the hard part for sure. I have redone cylinders up to 10 inch and getting that 3" nut needs some serious power. We had a hydraulic nut breaker in a proper cyl bench. Doing them in the field was nearly impossible. Even the pro's stack em up like that. It is just too easy to get a seal in wrong. As usual cleanliness is next to godliness esp in hydraulics. You have all the tools you need bud. Aside from the castle nut wrench. A bucket of hot oil sure helps getting them back on. Thanks bud, good post my friend.
This is a great video. I use it every time I repair a hydraulic cylinder on my BT751 Backhoe. So, thanks so much for taking the time to make it. I would only add one thing, besides the fact that the little seal setter assembly you spoke about is on back order, I used a different method to get that particular hard seal back on. First I lubed it up in Hyd fluid. Then I put the o ring on the piston where it goes underneath the thin hard seal that's the problem. Then, I hooked one side of the seal into the seal slot on the piston and pushed the seal opposite edge over the side of the piston with a little effort but easily doable. So try it like this. You just hook one side of the seal into its slot than push the other side of the seal over the edge of the piston and down into it's slot. Now in the process the seal my have twisted a bit, so work that out. Also when the seal is in place it may have one edge raised up higher than the other. What I did is put the piston back on the rod and screwed on the nut a ways. Then I pushed the piston into the cylinder (lubed up of course) . May be a little hard at first but drop the whole assembly cylinder end first on a carpet piece or some thing on the floor and the cylinder and shaft will proceed into the cylinder. Then just take the piston back out of the cylinder and you can see the seal is seated perfectly. But, make sure there is no twist in the seal before you do this!! Do this only when the seal is correct in the slot (but the o ring maybe is pushed to one side of the slot so it raises up one edge of the o ring more than the other.) Seems to work for me.
I have rebuilt tons of hydraulic cylinders and have never used such a tool to install that seal on the piston. They are very stiff and fight to go on but with the use of a tube of Parker lube, they go right on with no problem.
Hey Kevin, excellent video! I learned a lot of good stuff from watching it and your other video in preparation for rebuilding the 4 loader cylinders on an older Kubota B1750D small tractor with a 1640/A loader and backhoe. The Amazon link for the "Piston Rod Seal Up U-Cup Installation Tool" was priceless as I had one hell of a tough time installing the U cup seals in a pair of Bobcat 4 in 1 Bucket cylinders a few years ago. That tool, which I did not realize even existed, would have saved me hours of frustration trying to get those seals in properly and they are well worth the price!!! Thanks again!
Very good and very helpful video. Nice job and thanks for doing this for us. One thing that would have been nice would have been an initial review of the seal rebuild kit just to kind of set the stage for what all needed to be replaced. Just a suggestion but all in all great video. Thanks.
I just resealed both boom cylinders on a LA211 loader. Seals went on fine and everything was smooth but each end piece that has the 2 blue seals (not o-rings) (the piece that screws into the cylinder housing) when I pressed it back onto the cylinder the very end of the seal pealed off. And that happened on both of them no matter how lubricated I made the seals/cylinder for it to slide on easy. I don't think its leaking but should I be concerned?
Thanks a bunch! Just did a loader on my 3031. Dust cups were rotted to hell. I was an inch away from ordering that tool for that hard seal but fought it to the end and got it on. Real pain in the butt but it can be done. By the time I got the seal kit, 27mm and the u cup seal wrench I was in it about $200(I bought an impact socket set). Seal kit was a little over $100. Dealer wanted $280 to do it. I'll probly order the other tool for next time, that hard seal was a monster and theres 3 more cylinders I'll have to do eventually. Great video!
Really enjoyed this video. Job well done. Another day in Kevin's Classroom :) Looking forward to the update in the future. Thank you for sharing. Be well.
Thanks Kevin. As usual the proper tools sure make doing the job easier. Thanks for the links in the description. All the best to you and yours! Norm in Arizona
Hello Kevin, Thank you very much for your video. I think i can replace the seals on my L48 Kubota boom cylinder after watching your video. Few questions, If the hard telflon seal is ok? why replace it.? Instead of a spanner wrench would you use a pipe wrench or a cloth spanner .? I thank you for your time and i will play it foward. Best to you, Mike
If the hard seal is ok that would be up to you if you want to replace it but you are in there and will come in the kit. I do think the pipe wrench would work fine. You owe me nothing I thank you so much for watching my video and the comment.
Great explanations. We uploaded a similar video to our channel not long ago. I had a good friend who runs a truck and equipment shop help with the rebuild.
@@Robinson-Homestead went well. One top you shared that I didn’t do but would have been helpful was loosening the collar on the cylinder before removal. He told me to just bring the cylinders to him and we were able to get them loose, but it definitely was tougher to hold still.
@@Robinson-Homestead Thanks, I've been researching other videos about rebuilding hydraulic cylinders, as well, because I recently bought a 1981 Kubota L245DT loader and need options for parts. PS; when u r trying to show the inside o-ring u might want to try flashing some light from below to see better from above. Good presentation.
Did you use Kubota parts? I have a tiny steering cylinder in the shop right now, and I was hoping they could use aftermarket parts. Kubota wants $130 for a set for this cylinder. I would have ordered the seals and O-rings myself, but I don't know how to measure the old ones and decide what to buy.
Great vid. But the tools are over $200. I wonder how much your local Kubota dealer would charge to replace the seals on a disassembled cylinder. Surely not more than an hour of labor?
That piston seal is a Teflon seal. Pretty common in automatic transmissions. You actually stretch them to put them on and then the tool resizes them to proper size. The tools make it nice to size them. You can usually use the old bushing around the Teflon and then use a hose clamp around the bushing and tighten it until it stops.
Great video Kevin. How in the world did you find that tool (and in the correct size) from American Racing? I checked it out and the tool is actually listed for a transaxle repair but it sure worked slick here! I really like how it got that seal on without damage. The price is a bit of a bummer for a one-size tool - my Kubota B21 TLB is getting old and there's many different size cylinders on it. Any additional info you may have on how you sized the tool to the cylinder would be appreciated! I'm about to dive into a boom cylinder rebuild on the backhoe attachment. It's a Kubota BT751 backhoe. I will soon know if I will be needing a similar tool for it. Thank you! Larry
There are definitely different size tools for different cylinders I will be calling freedomracingcom and seeing if they have different size tools. I have one right now that is a different size so if I get the tool I will do the video. Thanks for the comment and watching.
@@dony.9014 a fernco is a rubber connector with a clamp on each end to connect 2 pieces of pipe together. I didn't want to use just a hose clamp out of fear of grooving the seal. The 1.5 inch is the size that fits the piston/seal. Just tighten the clamp down. I put the metal clamp over the seal and it closed up great. Good luck
You reinstalled the piston onto the rod backwards. the wear ring should be at the bottom of the cylinder. It's not that big a deal, but it is still wrong. You can soak the teflon seals in 180-200 degree water to warm them, wipe them dry quickly, oil and they will stretch right over the piston.
Everything was fine but you put the end where the nut goes on backwards , maybe it worked but take a look at your video . In the beginning it was on one way and at the end it was on backwards .
I will have to do that for my case Skidsteer no leak outside but maybe internal, forks will drop down over night EDIT now have added an old kubota with a bad seal for the bucket cylinder L402 loader
Hey Ed, I saw your comment here. I have a Case 1835C Skid steer and I will be pulling it into my garage to do a complete overhaul on. Going to do all four rams, run new hoses, pull the radiator and send it to get flushed and checked, etc etc. My dad had it for many years and I basically inherited it. It will be a little bit of a challenge - but looking forward to it.
Another video recommended heating the teflon seal in oil, I assume hydraulic oil, to 200 deg F (no hotter), then remove from oil bath and hand install. Looked easy on the video. The seal should shrink as it cools.

no i don't but i will try and get them for you,it's my friend's machine
Contact your Kubota dealer.
Great video, very detailed
Glad it was helpful!
Great job! I'll bet it cost a fraction of what a dealership would charged to do it! Thank you for sharing!
You got that right thanks for watching Paul.
I couldn't get a rebuild kit for my L2650gst from the local Kubota dealer.
I have the same tractor and loader. Can you give us the rebuild kit number? I did not see it in your writeup
We picked the kid up from Kubota
Are all kubota cylinders the same? As far as rebuild and sequence of seals...
Sorry but i don't know that was the first one i did.
Did you use Kubota parts? I have a tiny steering cylinder in the shop right now, and I was hoping they could use aftermarket parts. Kubota wants $130 for a set for this cylinder.

I used all Kubota parts sorry for the late comment.
@@Robinson-Homestead seals for the steering cylinder are outrageous, but the big loader seals are cheap. Strange.
where did you get the seal rebuild kit?
Call the manufacturer of your machine
This is awesome thanks for posting this. Question do all 4 cylinders use the same seal kit even though they are different lenghts.
Not all of them
Great vid. But the tools are over $200. I wonder how much your local Kubota dealer would charge to replace the seals on a disassembled cylinder. Surely not more than an hour of labor?
Not sure I have 2 Kubota and lots of cylinders rebuilding cylinders can get expensive thanks for the comment.
They charge $175. per cylinder plus the seal kit.
Good video, but did you put the piston on upside down on reassembly? I'm waiting on parts to do this same job.
That piston seal is a Teflon seal. Pretty common in automatic transmissions. You actually stretch them to put them on and then the tool resizes them to proper size. The tools make it nice to size them. You can usually use the old bushing around the Teflon and then use a hose clamp around the bushing and tighten it until it stops.
Thanks for the info!
I was think hot water to soften and expand it, then hose clamp to resize it
I am pretty sure that you put the piston on bk wards
Thanks for watching.
Kevin, very good. what about putting the piston back in the cylinder? Also would like to see more b-roll face shots.
Next time thanks for the comment Steve.
Perfect job bro 👍👍
Thanks for the comment.
How did you find out that tool was the correct size?
we measured the plunger
Great video, I have to do the same cylinder on a 1153 kubota loader, hope its the same.
Make sure you measure the outside of the seal before you order the tool.
You'd think this was a JD cylinder rebuild with all the special tools...damn Kubota

The price is a bit of a bummer for a one-size tool - my Kubota B21 TLB is getting old and there's many different size cylinders on it. Any additional info you may have on how you sized the tool to the cylinder would be appreciated!
I'm about to dive into a boom cylinder rebuild on the backhoe attachment. It's a Kubota BT751 backhoe. I will soon know if I will be needing a similar tool for it. Thank you! Larry
There are definitely different size tools for different cylinders I will be calling freedomracingcom and seeing if they have different size tools. I have one right now that is a different size so if I get the tool I will do the video. Thanks for the comment and watching.
That nut is Called a Packing Glan nut.
Thank you Charles.
Instead of buying a 144.00 tool, I used a 1.5in fernco and that compressed the hard plastic yellow seal from. the piston.
Cool thanks for sharing.
What is a 1.5" fernco?
@@dony.9014 a fernco is a rubber connector with a clamp on each end to connect 2 pieces of pipe together.
I didn't want to use just a hose clamp out of fear of grooving the seal.
The 1.5 inch is the size that fits the piston/seal. Just tighten the clamp down. I put the metal clamp over the seal and it closed up great.
Good luck
Hello could anyone by any chance be able to tell me what the names of the 2 special tools for taking it apart please and thank you
How much is it for a professional to rebuild four hydraulic rams on the front of your LA272 kabota
Sorry James but i don't know
Around $500.00 per pair…
Where can I find the link for the spanner wrench and O ring tool? Thanks
I have a link in the description
What is the name of the tool you used?
Nice... say how or can I order seal kits on line?
Check my description there should be a link.
Messicks. They’re 25 bucks. Screw a dealer.
Not snug but dam tight is best 😊
Thanks for the comment.
Anyone notice he put the gland in backwards?
Still working fine today thanks for the comment.
Very cool video
Glad you enjoyed it
A vise and some poly baling twine will install piston seals in 10 seconds.
Can you explain how to do the baling twine? Thanks.
Say no to gloves kids, it feels better without them.
Thanks for watching
Kevin, on the cylinders did you have to cap the lines on the tractor to keep air out. When you took the lines loose?
Know Jim.
Trying to order these seal and rings for the same tractor do u have a parts number where I can order these at please and thanks u
Find a Kubota dealer in your area they should help you.
You reinstalled the piston onto the rod backwards. the wear ring should be at the bottom of the cylinder. It's not that big a deal, but it is still wrong. You can soak the teflon seals in 180-200 degree water to warm them, wipe them dry quickly, oil and they will stretch right over the piston.
Thanks for the comment and watching
Thank you . Very helpful)
Thank you for watching and the comment.
Everything was fine but you put the end where the nut goes on backwards , maybe it worked but take a look at your video . In the beginning it was on one way and at the end it was on backwards .
Thanks Alezandra Espinoza.
Kevin, thanks but can’t find the expanding tool. Someone said to try hot water.
I tried hot water didn't work for me.
The hot water worked great. Did 2 cylinders in no time.
@@mikemagoo3352 how hot did have to have your water Mike.
I got the water to a boil.
@@mikemagoo3352 thanks Mike.
yikes. lol came for the part number on the seal kit. witnessed a sjit show.
I will have to do that for my case Skidsteer no leak outside but maybe internal, forks will drop down over night EDIT
now have added an old kubota with a bad seal for the bucket cylinder L402 loader
It may be the valve leaking off I will do a video that may help us Ed.
Most leak down,Don't suspend things overnight
Hey Ed, I saw your comment here. I have a Case 1835C Skid steer and I will be pulling it into my garage to do a complete overhaul on. Going to do all four rams, run new hoses, pull the radiator and send it to get flushed and checked, etc etc. My dad had it for many years and I basically inherited it. It will be a little bit of a challenge - but looking forward to it.
@@keigan9006 let us know how it goes
You want to loan me your tool? Freedom out of stock
State you in?
@@Robinson-Homestead Rhode Island
@@Robinson-Homestead I have to do my kubota bucket cylinder could I rent that tool from you to put in that hard Teflon seal? I am in N.W. In.
@@Robinson-Homestead What is your e-mail address
Another video recommended heating the teflon seal in oil, I assume hydraulic oil, to 200 deg F (no hotter), then remove from oil bath and hand install. Looked easy on the video. The seal should shrink as it cools.
Having to get that special tool is BS my friend. Oh well.
For sure not cool.
