  Caution
When installing a new base engine, it is essential that the clamping pieces for the injectors are tightened to the specified torque → Rep. gr.23 after installing the high-pressure pipes. The clamping pieces are only secured hand-tight at the factory so the injectors can be aligned during installation. If these instructions are not observed, the engine could be damaged.
