Camshaft: Service and Repair
Removing and installing camshafts on 4.8-liter DFI engines
Preliminary work
1. Remove camshaft controller.
2. Remove camshaft timing gears.
3. 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 then 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.
