Section 193 (Clutches - 5-Series (E60)): Description

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2005 BMW 545i, 2005 BMW 530i, 2005 BMW 525i, 2004 BMW 545i, and 2004 BMW 530i. However, it is still accessible from the selected car via links, so may be relevant.

A specially developed Dual-Mass Flywheel (ZMS) is used with the H-gearbox. Because the 6-speed manual transmission has more gears, the flywheel is modified to compensate for vibration and noise. In this flywheel, the 2 masses are connected via inner and outer dampers (rubber like damping material). The masses are now supported by a plain bearing (no longer in a ball bearing). The plain bearing requires less space and enables an additional inner damper to be used. The transmission input shaft is supported through the flywheel in a needle bushing with a roller pilot bearing. The flywheel is connected to the crankshaft flange with Torx socket bolts. Beginning 3/2003, BMW introduced new heavy metal-free friction linings which satisfy the requirements of used car regulations.
