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

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.

Removal of eccentric shaft is described separately from installation.

NOTE: The work steps are only described on one bearing position. The procedure is identical for the other bearing positions.
