Luk DMF081 Clutch Flywheel

LuK DMF081 Dual Mass Flywheel

The LuK DMF081 is a dual mass flywheel engineered for specific Mercedes-Benz applications, including C320 and SLK320 models. Built around the original LuK DMF design, it is tuned to the vehicle’s drivetrain requirements to help maintain smooth power transfer and reduce stress on related components.

Key Features

• Dual mass flywheel design for Mercedes-Benz transmission applications
• Flywheel diameter: 24 in. (9.449 in. metric listing also provided)
• Flywheel inner diameter: 15.5 in. (6.102 in. metric listing also provided)
• Flywheel cup depth/step height: -0.469 in. (-11.9 mm)
• 144-tooth ring gear
• Part number: DMF081

Detailed Description

LuK DMF081 is a clutch flywheel built as a dual mass flywheel for select Mercedes-Benz rear-wheel-drive passenger cars. It is listed for 2003-2004 Mercedes-Benz C320, 2001-2004 Mercedes-Benz SLK320, and 2001-2003 Mercedes-Benz C240 with engine number note 31757521 on the applicable C240 listings. The DMF design is used to isolate drivetrain vibration and support smoother engagement than a solid flywheel in the same application. Part number DMF081 is also referenced for interchange with 1120301305, 4150118100, and NDMF081.

What It Helps Address

• Drivetrain vibration felt during acceleration or shifting
• Harsh clutch engagement in manual transmission service applications
• Excess wear on engine mounts caused by torsional vibration
• Gearbox stress associated with improper flywheel design
• Crankshaft damage risk linked to solid flywheel substitution

Installation Notes

Verify engine number and vehicle application before ordering, especially for 2001-2003 Mercedes-Benz C240 listings that note engine number 31757521. Confirm the 144-tooth specification, flywheel diameter, inner diameter, and cup depth/step height against the original part. Professional installation and inspection of the clutch system, release components, and mating surfaces are recommended during flywheel replacement.

Quality Assurance

LuK supplies OE-style drivetrain components and the DMF081 follows the original dual mass flywheel concept for application-specific tuning. This part is cross-referenced to 1120301305 and 4150118100 for the same application.
