NH 1037 Bale Wagon Hyd. pump pressure?

So with the 2nd table struggling to lift with a load and the 3rd table (load rack) wont even hardly move when loaded, I checked the pump pressure and it is only 1500 psi. Does anybody know what the pump pressure should be? I myself think it should be more like 2500-3000 psi.
 
Not really sure about the pull types. Pretty sure our 1069 relief pressure is set at 2000psi. Wouldn"t think the smaller wagons would be higher than that. Did this just happen all of a sudden like? If you get a valve that doesn"t center, this will be the result. On ours it"s usually the push off feet. Try working all the levers back a forth a couple times and see if it will get better.

A AG mechanic said about 2500-3000 PSI. I been through it from front to back and everything is perfect except the lifting of the tables. I"m going to order a shop manual that will tell me for sure how much GPM and PSI that pump should put out so I can make a winter project rebuiling the pump. Kits are avialible but first I need to tare it down and see if it will take a kit first. New pumps are $1750, reman pumps $1000, kit $170.....Thanks
