D-12 Hydraulics Not Working

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I have an early D-12 (serial #1555) with Traction Boost hydraulics that have not been used in several years.  It is plumbed with one ram cylinder and looks original compared to the IT manual.  I get no action moving the hand control lever.  Since the pump is cam driven off the pto shaft I have had the pto engaged.  It does not matter if the flow control knobs are all the way in or out.  The fluid is full and very clean.  Would like some ideas on what to do before I start breaking connections.  Some thoughts are a fluid chjange or maybe just running the pto for a time and maybe the cam actuated valves will free up.  Looking for some experience based advice.
