G1355 Hydraulics

Quick question on G1355 hydraulics. With an implement hooked up to either set of hydraulic outlets, the outlets have little or no power. Not even enough to unfold the wings on a cultivator. The hydraulics worked fine one day, and then all of a sudden not the next day. The 3PTH and power steering still work fine, so I'm thinking the hydraulic pump is ok. Any ideas? Is there a relief valve or something that might be stuck? Just looking for some advice before I move forward on this.
 
I'm getting little or no pressure at the couplers. A couple of PSI if lucky. Is there a flow divider or relieve valve or something that might be stuck one way?
 
I am curious too. You might want to post this on the Oliver site.
They have some guys on there that really know these
hydraulics. Periodically mine will seem to not put any pressure
out (it will lock into the up or down position but when the
cylinder reaches end of stroke, the pressure just stops and
doesn't kick the lever into neutral???) the cylinder does not
drift, so I have not concerned myself with it, but it sounds like it
may become a problem??
 
I checked it with a gauge. Little or no PSI at the couplers. What adjustments can be made on this system? Seems odd that it would work fine one day and then suddenly not the next.
 
Well what reading did you see on the gauge? 2 suggestions #1. Check the speed restrictor on the inlet cover to the remote valve. I don't know if you can shut the flow off completely or not.#2. check the coupler. Remember the line that supplies oil to the 3 point also supplies the remote valves. You need to also check the compensator setting.
