1. O-ring: in the cylinder head cover; replace after removal
2. Copper washer: replace after disassembly
3. O-ring: replace after disassembly
4. Injector: re-installable injectors and high pressure fuel lines may only be installed on the same cylinder; consider catalog number
5. O-ring: replace after disassembly
6. Fuel return line: to the fuel tank; prevent kinking, damage or blockage; do not disassemble; after replacement, fill the fuel system with fuel / remove air from the system
7. Pressure plate: Re-installable injectors and pressure plates may only be installed on the same cylinder
Carefully! Risk of engine damage. After installing a new cylinder block and mounting the high-pressure lines, it is absolutely necessary to tighten the pressure plates of the injectors to the prescribed torque -pos. 8- for aligning nozzles when installing high-pressure lines. The pressure plates are hand-tight only when shipped from the factory.
8. 9 Nm + tighten by 180° (½ vol.): replace after disassembly
9. Pressure line, 28 Nm: between the fuel rail (pressure accumulator) and nozzles; observe all instructions for the installation of high-pressure pipelines; install without mechanical stress
10. Reducing sleeve: in the cylinder head cover; replace if damaged
Mounting position of pressure plate
One pressure plate fixes respectively two nozzles. The seal -arrow- of the pressure plate must point downwards.
