changing seals in a hydraulic cylinder

[jinmared]

I need to change a bad seal in my dump valve cylinder on my jinma FEL JM ZL-30.Can anyone give me advice on how to do this?
A cylinder schematic would be nice also
I ran a check on both cylinders and only the top hose on the right side leaked fluid by.
Thanks

If you are just changing seals on the lines that's quite easy. If you are changing seals within the cylinder it's still pretty easy. I took mine apart for the first time abput a month ago. You can use the stands to prop the FEL. I only took the upper end of the cylinder. Disconnect the lines. It will slide off. Make sure to keep it all clean. dirt will tear up the inside of the cylinder and system. Put it back together and bleed the air out. Question do you have seals already hoses or cylinder and where did you get them I'm still waiting on mine.
