Twin Mass Flywheel - E82 E89 E90 E92 E60 - N54 8-Bolt Crank (before 1/2009)

OEM replacement flywheel for early N54 cars: 2008-1/2009 E82 135i, 2007-1/2009 E9X 335i, and 2007-2010 E60 535i.

Modern BMWs use a dual mass flywheel (DMF) to dampen driveline vibrations and help make clutch operation smoother, but as many BMW owners realize, they don't last forever. Sachs, an OEM supplier to BMW, recommends replacing the DMF with every other clutch. But in some cases the clutch has been abused so much that damage extends to the flywheel. If you're planning a clutch job consider also buying a new flywheel to have on hand.

There are symptoms of BMW DMF failure and needs to be replaced: build-up of clutch material or damage to the clutch contact surface, excessive play between the two halves of the DMF (if the outer flywheel section can rotate more than 20mm in either direction), and grease leaking out from inside the flywheel assembly. A worn DMF does not just impact performance or clutch operation, it's a big safety issue as well. A DMF that breaks apart can be catastrophic to the transmission as well as dangerous to the driver and passenger.

Includes new pilot bearing (BMW #21207536792). Does NOT include new flywheel mounting bolts, which are required (BMW #11227520706, see below).

Only fits cars made before 1/2009 production date.
