Bosch fuel injection pump
Warm up the engine.
Set the pump lever to the maximum speed position.
Connect the tachometer according to its instructions. Loosen the lock nut and, turning the adjusting screw (arrow fig 255), set the required maximum speed. Tighten the lock nut again and secure it with paint to prevent it from loosening.
Adjust the maximum speed to (5450±50) rpm for a diesel engine and (5100±150) rpm for a turbocharged engine.
