Kubota L2500 with a LA450S front end loader. I started this project with zero experience and about zero knowledge of hydraulic cylinders. Most of the time was spent researching what seal kit to order and what tools I'd need. Turns out I didn't need any of the specialty tools. I was able to loosen the head gaskets with a pipe wrench and install the inside piston seal with fingers, surprisingly easy. The rigid yellow Teflon seal was the trickiest. I tried heating it but ultimately found massaging with fingers and using an O-ring pick did the trick. I used a hose clamp to compress the seal afterwards (as several people suggested in videos). Don't know if it was necessary. A mistake I made that added a lot of confusion and time to the project was that I didn't realize the piston wiper seal included a rigid ring that I had to pop out with a screwdriver (I scraped the rotting rubber clean and thought the ring was part of the piston). After that light-bulb moment everything made sense and went well. Replaced seal kits on both bucket cylinders. No leaks after 3 weeks. Hopefully another novice will find this helpful. I sure relied on the internet to get through this project.

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.
