I have a 65 C30 it has a Daybrook (name on plate) hydraulic tailgate it works but not correctly there is a valve that you need to open to lower and close to raise. The valve looks to be a standard globe type valve. The is a push button type switch that does not work but it looks like it was used to control the unit it is a electrical switch. Not sure if any of this makes sense or not but what I a need to know is if anyone knows how this should work. 2nd question is there a way to drain and refill this system. I do not see a plug to refill it does have a relife valve on top and blew out some green fluid when I 1st ran it.
