11 37 008 Removing and installing/replacing right eccentric shaft (N62 to 9/03): Installation

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2005 BMW 745i, 2005 BMW 745Li, 2004 BMW 745i, 2004 BMW 745Li, and 2003 BMW 745i. However, it is still accessible from the selected car via links, so may be relevant.

Installation of eccentric shaft is described separately from removal.

IMPORTANT: Danger of mix-up:

Version up to 2/03 of cylinder bank 1 to 4: 

In the version up to 2/03, the eccentric shafts are different for cylinders 1 to 4 and 5 to 8 and must not be mixed up.

The eccentric shaft of cylinder bank 1 to 4 has the part number 7 513 754 stamped between cylinders 3 and 4 and a "flat area" on the collar between cylinders 1 and 2.

IMPORTANT: Danger of mix-up:

Version up to 2/03 of cylinder bank 5 to 8: 

The eccentric shaft of cylinder bank 5 to 8 has the part number 7 513 755 stamped between cylinders 5 and 6 and has no "flat area" on the collar between cylinders 5 / 6 and 7 / 8.

IMPORTANT: Danger of mix-up:

If none of the markings described above are present, then the eccentric shaft will be a new-version shaft.

The new-version eccentric shafts are identical parts.

Depending on the side on which the lever for the torsion spring and the magnet wheel are fitted, the eccentric shafts are used for cylinders 1 to 4 or 5 to 8.

NOTE: Lubricate eccentric shaft at bearing positions.
Replace needle bearing (1).
IMPORTANT: Needle bearings break off very easily when installed.

Carefully press needle bearings (1) apart at split position only to such an extent that they can be fitted over eccentric shaft.

IMPORTANT: The position of the eccentric (3) is crucial to fitting the lever (1) and the installation direction in the bearing bridge described later.
Incorrect assembly will result in engine damage. 

Cylinder bank 1 to 4: 

As shown in the illustration, the machined surface (3) on the eccentric must point left and the groove in the eccentric shaft must be pointed upwards at an angle.
