im not herer to argue with ya I had a qusetion I asked you didnt like the ansewer. The original question is this the releif valve and I got alot of ansewers but that one good day sir.
The relief is open when you dead head the boom. Thats the foundational basis of the test.
Your loader valve was available as 3 or 4 position and with or without regenerative dump. What position did you test and was it a regenerative position?
The help you got in posts #6 and #8 would have saved you tearing the priority valve apart. Its been helpful - you just ignored it.
What I am trying to politely tell you now is the chances you have 1300 PSI on bucket and 2000 PSI on boom is damn near zero. Something is probably wrong with your bucket pressure test just like the flow test you did in #5.
