TECHNICAL INFORMATION
The high pressure pump is preloaded by the piston spring and must be removed by alternately unscrewing the screws without tilting.
Before installing the high pressure pump, the cam of the high pressure pump drive must be turned to bottom dead center.
If necessary, turn the engine in the direction of engine rotation on the central bolt of the crankshaft, otherwise there is a risk of piston breakage of the high pressure pump.
