problem started when the pump keyway sheered off and tractor quit running(distributor drives off hyd. pump) took it all apart found some pitting but no debris. got it running again and now no hydraulics and pump gets super hot in 1-2 min. lines dont even get warm (no flow). removed and cleaned the filter.(was partially plugged).didnt help.but now know problem must be in pressure side(blew through all lines and cavitys) removed the valve bodies and took all apart and found nothing wrong no debris, nothing was stuck or broken and everything was installed correctly according to manual. we have had trouble in past with the flow control valve blowing out but beleive its because the snap ring groove is so erroded away, we built a plate to help hold it in and always were able to just fill it back up and it would work.
can anyone help i am stumped, dont know what to do next
with lines cracked loose i"ve cranked engine and know pump is pumping but dont know if enough.
