How do you set injectors on a Nh220 cummins engine?

To set the injectors on a NH220 Cummins engine, first ensure the engine is at top dead center (TDC) on the compression stroke for the number one cylinder. Then, using a dial gauge or a feeler gauge, adjust the injector heights to the specified clearance, typically around 0.020 inches. After setting the injectors, tighten the injector hold-down bolts to the manufacturer's torque specifications. Finally, recheck the clearance to ensure proper adjustment.
