Installing high pressure pump
Prepare for the installation of the high pressure pump
Rotate the cam of the high pressure pump drive to the BDC position
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.
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.
- 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.
- Loosen cover (1).
- Rotate the engine with the special tool 0 493 380 (11 6 480) in the direction of the arrow until the cam of the high pressure pump drive is at the BDC position.
- Check the threads (1) on the high pressure pump flange for sealing compound residue: Remove sealing compound residue as needed.
- Clean the thread (1) with a thread cutter M6.
- Make sure that no contamination gets into the engine.
- Cover opening at the high pressure pump flange with suitable materials.
- Replace the seal (1).
Parts: Gasket
- Feed in and install high pressure pump (2).
- Replace the bolts (arrows).
Parts: Screws
- Position the screws (arrows) on the high pressure pump (2) and alternately
in steps of 90°.
Compliance with this specification is imperative to make sure that the piston will not break due to twisting.
