Installing high pressure pump

Further information is available.

NOTE: RISK OF DAMAGE
Damage to the engine.
If the engine is manually rotated in the wrong direction of rotation, the engine can be damaged.

Only rotate the engine manually in the correct direction of rotation: a) clockwise when looking at the damper, or b) counterclockwise when looking at the chain drive, b) applies only if the timing chain is installed in the rear.

NOTE: TECHNICAL INFORMATION
Only G05 and G07
On vehicles with an active stabilizer (ARS), the fan cowl must be removed to crank the engine.
For additional information see: 17 11 035 REMOVING AND INSTALLING/REPLACING THE FAN COWL WITH ELECTRIC FAN

NOTE: 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.

Place the depth gauge (1) flat onto the high pressure pump flange.
Turn the engine on the central bolt in the direction of engine rotation until the camshaft has reached the BDC position.
The depth gauge (1) is in the deepest position.
