Luk DMF016 Clutch Flywheel

LuK DMF016 Dual Mass Flywheel

The LuK DMF016 is a dual mass flywheel engineered for BMW applications that require precise drivetrain damping and smooth clutch engagement. Built around LuK’s original-equipment approach, it is tuned to the vehicle’s specific drivetrain needs rather than using a one-size-fits-all solid flywheel design.

Key Features

• Dual mass flywheel construction for drivetrain vibration control
• Flywheel diameter: 23 in. (9.055 in. also listed in metric/alternate reference data)
• Flywheel inner diameter: 14.64 in. (5.764 in. alternate reference data)
• Flywheel cup depth/step height: -0.197 in. (-5 mm alternate reference data)
• 113-tooth ring gear
• OE-style fitment for BMW 323i, 323is, 325i, 325is, and 525i applications

Detailed Description

LuK DMF016 is a clutch flywheel designed to maintain the damping characteristics expected in BMW drivetrains. The dual mass design helps isolate engine pulses from the transmission, reducing stress on related components and supporting smoother clutch operation. This part number, DMF016, is commonly referenced for 1998-1999 BMW 323i and 323is, 1992-1995 BMW 325i and 325is, and 1990-1995 BMW 525i applications, including 1990 BMW 525i built from 09/01/1990.

This part cross-references 21201223418 and DMF91110 for the same application. If you are replacing a worn BMW flywheel, DMF016 provides the OE-style dual mass layout specified for these vehicles and is a direct match for the listed BMW 323i, BMW 325is, and BMW 525i fitments.

What It Helps Address

• Excess drivetrain vibration at idle and under load
• Harsh clutch engagement or driveline shudder
• Premature wear on engine mounts and transmission components
• Noise caused by a worn or damaged flywheel assembly
• Stress transfer that can contribute to crankshaft and gearbox damage

Installation Notes and Tips

Confirm the vehicle’s year, model, and build date before ordering, especially for the 1990 BMW 525i with the 09/01/1990 note. Inspect the clutch system, release components, and related drivetrain parts during service so the new flywheel is installed into a clean, properly matched assembly. Verify tooth count, diameter, and step height against the original part before installation.

Quality Assurance

LuK is known for OE-level drivetrain components, and this DMF016 flywheel follows the brand’s application-specific tuning approach for BMW fitment. The dual mass design is intended to preserve the damping characteristics expected by the original drivetrain layout.
