Loader Tractor D14 Hydraulic Control Valve ?

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

   My 1960 D-14 tractor with a Superior Mfg. (Chicago) Loader has the original 2 handle control valve, with lift and tilt.  The system works off the front mounted pump and the tilt circuit has had a slow leak down for while now.   System is full and clean.  Cylinders are not the culprit.. it is the valve/tilt circuit.    REPAIR OR REPLACE?  Is it likely seals or usually worse? 

Although fairly competent to wrench on all my old tractors and equipment,  I am COMPLETELY without experience on control valve/hydraulics.   REPAIR OR REPLACE?   I see several basic 2 handle control valves offered for a few hundred dollars , although I would have to sort out what I need.  Are they plug and play or require setup and flow gauge type pressure measuring tools etc?  

I sure don't want to take the tractor out of service for a long time while and try to learn how to "fix" the valve unless it is fairly simple.   My guess is a repair done professionally (if even possible on a 1960 setup) will cost about the same as a new control valve but I have no idea?     Looking for some basic insight experience .  

Thanks
