New oil pump and bearings about 2 years ago. 40 psi oil pressure all the time.
Out using the tractor...40 psi while working. Dropped tractor to idle and got off to open a gate. As I came back, tractor was knocking a bit. 0 oil pressure. I shut down and checked the level...it was about middle stick. I put in an extra quart..no change. I tried cranking for a bit w/o ignition...nothing (normally would build full pressure).
I am thinking relief valve.
Anything to check before dropping the pan?
Thanks,
Dave
