Depending on the engine model, the injection pump control rod will link two, three, or four injectors to the engine governor.
Screws 1 and 2 are pivoted on the delivery control lever of each pump/injector B, unscrew the screws and remove spring 3.
When refitting tighten the screws 1 and 2 at a torque of 1,1 Nm and make sure that they stop on lever B of each pump/injector and not on rod A.
