Installing the two high pressure pumps

Installing the high pressure pump for cylinders 4 to 6

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
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 at the central bolt in the direction of engine rotation until the camshaft is in the BDC position.
The depth gauge (1) is in the lowest position.

Clean sealing surface (1).
Insert and install the high pressure pump (2).
Replace the screws (1).
Parts: Screws
Position the screws (1) on the high pressure pump (2) and tighten them in alternating order in 90° increments.

Compliance with this specification is imperative to make sure that the piston will not break due to twisting.
