Gentlemen. You are all very helpful.
Transit: Thank you very must for your story/information Did you also replaced your loader lines? And to a more flow PRV or just the PRV line size ?
J_J: Thank you for your explanation and the chart. My intention with the pump upgrade was to get the increase in speed not the force. According to the dealer the only difference between the pump is the flow out put, pressure rating is the same.
AKKAMAN: Yes the pressure test is next on the to do list of mine.
No, that would have caused clearance problems between the muffler and arms. Although there are some minor issues, I can live with them.
The joy stick for the loader has a built in prv, up grading the lines reduced the back pressure.
BTW, larger lines are harder to bend.
