I did one at a time, took pictures, and didn't rush. I used a pipe wrench to loosen the end and all 4 were quite easy, spanner would have been preferred but I didn't have one.
The one I inside side seal was flexible and I used my finger to install it, the special tool wasn't necessary. The stiff seal that is a tough one, I heated to 200 degrees in hydraulic fluid, clamped the piece to the bench, and used an ice pick. It stretched but went back in shape by just working it with my fingers. It slid onto the cylinder pretty well because of the beveled edge. I got these ideas from the other videos and they worked out very well.
The first one took about an hour but after figuring it out the others took about 20 minutes or so without rushing.
I wouldn't hesitate to do it again. My tractor is the Kubota L3000DT.

There's on tricky seal to install. You'll know it when you get to it. I tried the boiling water trick I found online, but it didn't work. What did work was careful brute force. This leaves the seal stretched. Wrap it in electrical tape and clamp it with a hose clamp. Put it in the freezer for a couple of hours. Works like a charm. 4 hours for both cylinders, of which half that was figuring out how to conquer this seal.

Always start by cleaning the hydraulic cylinder before removing from tractor, with special attention to the hydraulic hose connectors. Avoid getting any contaminates in the hose ends. Loosen the piston retainer collar while the unit is still mounted on the tractor. This is easier than performing the same operation on the workbench. Removing the piston and end cap is easily done with a bench vice and proper wrench. Do not secure the cylinder body in a vice, as it may be damaged from over tightening. Put the mounting end of the cylinder in the vice, and support the other end with a block of wood resting on the workbench. Replace all O rings and seals regardless of appearance. The rebuild kit will have more parts than you will need for your unit, but that is because the kit is designed for more than one type of hydraulic cylinder. All rubber O rings are easily removed and replaced, but the difficult parts are the seal that goes inside the end cap on the piston, and the plastic like ring the goes between the two split rings over the outside of the same part. Work the plastic like ring over the body of the piston by stretching it as you work it on. Once in place, it will seem to be ruined and all out of shape, but in a few minutes, and with a little massaging, it will regain its original shape. The inner seal is a little more difficult, but can be installed with a little patience and a trick. Not the direction of the flange and think about how it functions to hold the hydraulic fluid within the cylinder. Bend the seal in the shape of a U with one end in the seat and the opening of the U at the other end of the seal. It will pop into place with the first or second attempt. Inspect it to make sure it did not roll. Think about how it operates. Assemble in reverse order, and do not forget the outer seal. It is crucial in keeping impurities out of the cylinder. Once again, think about its wiping action when installing. Good luck

Busted one of the seals when putting it on so i used the exttra black one to do the center of the three seal piece and it worked, second arm i have done in two years , the dealer wanted 900 to do the job and the part was 59.00 plus shipping

Take pictures before removing old seals, and keep everything clean.

The hardest part of this job is getting the caps loose it's best to leave the cylinder on the tractor and loosen the caps with a spanner wrench although one of mine was so tight we had to use a 36 inch pipe wrench to loosen it and a set of o ring picks are very helpful, it's best to get the plastic seal that goes inside the cap warm because it make it pliable and easier to install it's a very easy job if you are good with tools

Very easy (is that one star or five?) with the right tools but these cost $125. Watch Kevin Robinson's "Kubota hydraulic cylinder rebuild" on YouTube. Take pictures of seals in place, and, once removed, orientated correctly
