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

Lol thank you so much for the comment and watching.

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...

Sean, thank you so much i appreciate the great tips on the o rings, thanks for watching.

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 KZread such a powerful information tool.

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.

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.

@@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.

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. 👍✌

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. 😡

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

Well done walk-through. A bit too much apologizing and equivocating. Anyone wants to gripe, let them.
