I have a 3010 deseil and I put a new oil pump in and when start engine I hav 25 psi at pto speed and when I try to adjust up or down the
pressure does not adjust when the engine warms up I loose pressure to 15 psi at pto speed I hav checked the oring on the oil filter canister and
it is good, I think there is a oil leak internally some where was wondering if someone had any ideas
 
Because of low oil pressure took apart and the pump gears were worn pretty bad, this motor cane from a salvage yard and I put rods and mains in and plastic gaged the new bearings and tractor ran for about 8 hrs and then the oil pressure light came on and would stay on till you had about 1500 rpm and i put a gauge in and when the engine got warn it would be around 14 psi and not adjust so I installed a new pump and I still have same issues as before
 
look for a pressue relief valve on front timing cover , it has a spring and seat, spring could be broke or weak, or seat bad
 
Remove the tach drive and pressure relief valve assembly. Behind the screw you are trying to adjust, there is a spring that pushes a flat spring against a seat. The steel seat sometimes moves in the aluminum housing preventing the flat spring from closing properly. The shoulder on the seat should be even with the housing surface.

its not in the timing cover on the 3010. its in the tack drive cover on the right side of the engine just the diesel pump

I checked that and it is correct I plasti gauged the bearing when I installed new rod and mains and they were .004, so I wonder if a cam bearing isn't loose
