muz123 1,192 #1 Posted April 3, 2016 Had a big hydro fluid leak on my 520H under about where the Assembly Valve is located. After losing all the hydro fluid, I took off the two rubber hoses to the Assembly Valve but did not notice anything obvious. Does the Assembly Valve ever leak? Thanks, Dave Share this post Link to post Share on other sites

All valve assemblies have "O" rings to contain the pressurized fluid while allowing movement. The only way to know where the leak is would be to put the hoses back in place, thoroughly clean everything, fill the system and run it until you see the leak. 12 hours ago, muz123 said: did not notice anything obvious If one of the hoses has a leak it could be a pinhole and pass a tremendous amount of fluid under pressure. Good luck and let us know how you do. Share this post Link to post Share on other sites
