How is the output pressure of a diesel engine lubricating oil pump regulated?

We need to make an adjustment.

Any LO pump has a relief valve or pressure regulating valve.

The supply pressure of the pump is changed by the adjusting screw, which in turn, sets the tension of the valve-pushing spring.

Turn the adjusting screw clockwise to increase pressure and counter-clockwise to decrease.
