How to Replace Excavator Hydraulic Cylinder Seal Using a Homemade Tools

Replacing arm cylinder seal for Hitachi EX120-1.

[@danagrey3534]

Coming from America, most mechanics would have a fit say doing this type of "field repair" in the dirt would contaminate the rebuild.But you guys got it done! I commented this on another of your videos and it is worth noting again. Regardless of where we are in the world, or race, color, language, income, religion and all of that, it is video like this that brings us all together to share our passions, our information and how the people of the world can get along, despite some governments or nations don't get along because of their leaders. I find your video very inspiring as well as educational. So keep up the awesome work and hopefully you can get more folowers, be more successful and we all can watch you grow and expand to more equipment! Awesome job and I learned a simple but better way to change or rebuild an dipper stick cyclinder!

Good job guys. Just a hint for putting the seals/o-rings on, leave them in a pot of hot water for a bit as this softens them up and they become more pliable. Thanks for sharing

[@MXHEAVYMACHINERY]

Wow thanks for the information. Gonna try that soon.

[@mapalomobileautodoctors1031]

What role did the ring squeezer play

[@MXHEAVYMACHINERY]

@@mapalomobileautodoctors1031 to let the seals fitted. Squeezing the middle seals before mounted in cylinder case.

Thanks

Good honest field repair. Not everybody can get a machine into a shop with controlled conditions. There have been many repairs like this up on some sidehill or logging road to get it done. Hot water or oil helps a lot to make the seals more pliable.
