I have that problem on my 8ns. Except for one 8n that I rebuilt the pump. It has good pressure. Iím thinking the engine was taken good care of by the previous owners. You canít put metal back on the cam journals or the crank journals. And just because you have good bearing clearance it doesnít mean the bore is round. Even when you hone the crank it will still be OS. The fix is to install an OS cam and Iím not sure you can get them for old tractors. Iím using a 7010 turbo diesel that starts at 25 psi and drops to 5 and wonder when it will break. It just keeps going. Good luck.
