Luk DMF017 Clutch Flywheel

LuK DMF017 Dual Mass Flywheel

The LuK DMF017 is a dual mass flywheel built for BMW 318i, 318is, 318ti, and Z3 applications with the correct OE-style fitment. It is tuned for the specific vehicle application to help reduce drivetrain stress that can occur when a solid flywheel is used.

• Dual mass flywheel design for smoother drivetrain operation
• Flywheel diameter: 21.8 in. / 8.583 in.
• Flywheel inner diameter: 14.64 in. / 5.764 in.
• Flywheel cup depth/step height: -0.197 in. / -5 mm
• 113-tooth ring gear
• OE-focused replacement for BMW manual transmission service

Fitment Details

Compatible with these BMW applications: Fits 1995-1999 BMW 318ti, N/A, Air Conditioning; Fits 1996-1998 BMW 318i, N/A; Fits 1996-1998 BMW Z3, N/A; Fits 1991-1997 BMW 318is, N/A, Air Conditioning; Fits 1991-1995 BMW 318i, N/A, Air Conditioning.

LuK DMF017 is engineered as a direct replacement flywheel for the listed BMW 318i, 318is, 318ti, and Z3 fitments. The dual mass construction helps isolate engine vibration from the transmission, which is important in vehicles where driveline smoothness and component protection matter. This part number, DMF017, is commonly selected when replacing a worn flywheel on BMW manual transmission applications that require the original dual mass design.

What It Helps Address

• Excess drivetrain vibration at idle and under load
• Premature wear on engine mounts from torsional shock
• Gearbox stress associated with solid flywheel conversions
• Crankshaft damage risk linked to reduced vibration damping
• Noise and harshness from a worn flywheel assembly

Installation Notes

Verify the flywheel diameter, tooth count, and step height against the original part before installation. This DMF017 application is specific to the listed BMW models and years, including BMW 318i, BMW 318is, BMW 318ti, and Z3 fitments. Always inspect the clutch system, release components, and related drivetrain parts during service so the new flywheel is installed on a clean, properly matched assembly.

Quality Assurance

LuK is known for OE-level clutch and flywheel engineering, and this dual mass flywheel follows the original application-specific design approach used for the listed BMW vehicles. This part cross-references Aisin (e.g., 50-2785) for the same application.
