Information
- During removal, note the installation position and allocation of the camshafts and bearing covers on a sheet of paper in such a way that they cannot be mixed up.
- Protect camshafts and bearing covers from dirt and place the components on a clean surface according to installation position.
- Slowly and uniformly loosen and unscrew all M6 screws (according to cylinder bank) -1 and 6-3 and 5-
on the camshaft bearing covers -2, 4 and 5-2, 4 and 6-
.
The bearing covers are marked E for intake camshaft and A for outlet camshaft. The bearing covers are numbered consecutively by cylinder.
The bearing covers are seated very securely in the cylinder head because of a dowel sleeve -3-1- . Jiggle free using a pliers if necessary. Place on a marked, clean surface.

Information
- The intake camshaft for cylinder bank 5 to 8 has a plastic loss preventer to prevent the high-pressure pump's drive coupling from falling off.
- If for some reason the plastic loss preventer was not installed, the drive coupling would fall off when the camshaft is removed. The high-pressure pump and its drive mechanism will still work even without the plastic loss preventer.
- Remove camshafts (according to cylinder bank) -1 and 2-3 and 6- and place on a marked, clean surface. Turn the intake camshaft for cylinder bank 1 to 4 so that it can be lifted up and out of the drive coupling for the vacuum pump.
