Camshaft: Overhaul
Removing and installing camshafts
Preliminary work
1. Remove valve cover. Disassemble the cross panel to do this.
2. Remove camshaft controller.
3. Remove camshaft timing gears.
4. The high-pressure pump must be removed first before the intake camshaft for cylinder bank 5 to 8 can be removed. The drive coupling of the
high-pressure pump prevents the camshaft from being removed.
Removing camshafts
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.
1. 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.

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
