looking for further advise on this dump ram...there are some I.D. tagsa with numbers on them. No visible manufacturer name other than the name Chelsea on the knob that is for the pump activation in the cab and the name Thermo King which is on the knob for the PTO. I have looked into the vent cap tube(about 1 1&2" dia) and saw no fluids. My confusion comes from, if I need to add fluids, from the info provided can someone tellme what type fluids should be added? This device is about a 1 square foot cube, with a small diverter valve on the top of it which has the hydraulic lines(2) that go to the ram cylinder. Also the knob in the cab which is marked Chelsea has a cable connection to this valve. Lastly if there is no knowledge re this can some one suggest a link?????? :confused:
