Repairing a leaking joystick control valve on a 2011 Doosan Dx 255 LC excavator.
hydraulic fluid was leaking past the O ring on the brass caps that plunge into the control valve allowing the machine to perform a hydraulic function.
I was able to get the correct seal kit with new upper components allowing me to leave everything inside the control valve body alone and successfully re seal the control valve.
I couldn't find a video on youtube referencing this repair so I figured I'd share.
