11 37 008 Removing And Installing/Replacing Right Eccentric Shaft (N62 From 9/03): Removal

WARNING: This page is about a different car, the 2005 BMW 645Ci and 2004 BMW 645Ci. 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.

Carefully tilt bearing shell (1) to one side and simultaneously remove towards top.

IMPORTANT: Danger of mix-up:

It is very easy to mix up left and right or front and rear on the eccentric shaft.

If necessary, mark the side on which the magnet wheel is fitted.

NOTE: Magnet wheel (1) is extremely magnetic.

After removal, place magnet wheel in a plastic bag to protect it against metal chips.

Release screw and remove magnet wheel (1).
