touch control and oil pressure problems

[4evr fixin]

I was having problems with my touch control loading the engine when lowered. When i lowered the plow the engine had to work pretty hard until the pump stopped. So i decided to rebuild it. In the meantime I checked the compression and decided to rebuild the engine. Now that both are done and the tractor is back together its worse. When i lower the blade it almost kills the engine and keeps straining until I raise it a bit. Also when I start the engine I have good oil pressure until it runs for about ten minutes and the pressure starts dropping to about zero. It takes a few minutes but it steadily drops.

Did you plasti-gage your bearing clearances? (Addressing the oil pressure problem)

The engine loading is normal behavior while lowering an implement. There was nothing wrong with your hydraulic system before you started. You now have a mal-adjusted stop for the lower end of the control lever movement. The procedure for adjusting the stop is in the Touch-Control Serviceman's Guide.
