- 1 - Nozzle, always replace with combustion chamber O-ring (teflon), replace O-rings, ensure correct installation position
- 2 - Support ring
- 3 - Fuel rail (Rail)
- 4 - Mechanical 1-piston high pressure pump with fuel pressure control valve -N276-. The fuel tank contains an electric fuel pump that delivers fuel at a pressure of approx. 6 bar for high pressure mechanical pump. When installing the injection pump, it is necessary to prevent the ingress of dirt into the fuel system. To mount the injection pump, relieve the pressure in the fuel system, install the fuel line without tension
- 5 - Roller pusher
- 6 - Fuel pressure regulator -N276-
- 7 - High pressure pump bolts, replace, 10 Nm
- 8 - Fuel line fitting, replace, 22 Nm
- 9 - Union nut of the fuel supply line, 18 Nm
- 10 - Charge air control flaps
- 11 - Gasket, replace
- 12 - Intake manifold
- 13 - Vacuum reservoir for charge air control flaps
- 14 - Throttle valve unit -J338-, throttle valve actuator -G186-. Throttle valve actuator angle sender 1 -G187- and throttle valve actuator angle sender 2 -G188-. After replacing the throttle valve module -J338, it must be adapted again to the engine control unit -J623-
- 15 - Intake manifold bolts, pre-tighten to 3 Nm and finally to 9 Nm
- 16 - Intake manifold flap potentiometer -G336-
- 17 - Fuel pressure sender -G247-, 22 Nm, lubricate thread with clean engine oil
