4020 Hydraulic Issue

I have a 64 4020 power shift that has dual hydraulics. One set works but the first set on right side does not release pressure. I put a gauge in
both ports and one port builds pressure to just over 2000psi and releases it and the other builds to the same pressure but will not release it.
Any idea on what the issue is would be appreciated.
 
It would appear that your valve needs to be overhauled. If you don't have a manual it would be good to get one (not an I&T please) or get it shipped to Tim S who will probably chime in here soon. (No charge for the plug Tim!)I would do it here for you but shipping it to and from Canada does get problematic. BTW your standby pressure should be closer to 2300 psi
 
Those dash hydraulics are a different animal to work on,,first check the linkage,if the holes are wobbled out it may not be moving far enough to make the valve work in that direction..and it may be in the float hole on the handle...
 
I will check that out, also if that is not the case are you the Tim that works on overhauling these? I won't be able to take the valve off the tractor until after mid May when I am done planting with it. If this doesn't work we will just have to use manual markers for planter.
 
Yes I do repair and bench test valves and pumps,,"but" the old style are not friendly to work on, if yours is acting up I would suggest swapping it out with a used one...
