JD 955 implement pump (gear pump)

   / JD 955 implement pump (gear pump) #11  
Can I simply plug a gauge into one of the SCV output quick connects and check the pressure that way (by operating the valve of course)? Or do I need to tee into a line somewhere?

If you do not have a QD fitting, you can also just disconnect a hose from
a FEL cyl and put a guage there. Those fittings are cheaper. You do
need to have the work circuit you use at the end of its cylinder's stroke
(extend or retract) so the RV opens. I also cap the open fitting to avoid
spills. Then start the tractor and operate the FEL valve.

I dont' have a loader (yet) so I'm just going to plug the gauge into one of the QD's. I have a bag full of the male QD's that I can just screw a gauge directly into.

Here is a picture of my gauge, couldn't post it earlier from work:

Well, the pump appears to be fine. I got the tractor running tonight and took an open ended hose and attached it one port at a time and flushed out all the SCV lines. Then I plugged my gauge into one of the ports and the gauge peaks a little over 2500 psi before the PRV opens and pressure starts to bleed down. If I continued to hold the valve open, the pressure would bleed down to about 2200 psi.
