Luk DMF019 Clutch Flywheel

LuK DMF019 Dual Mass Flywheel

The LuK DMF019 is a dual mass flywheel engineered for BMW applications that require precise drivetrain damping and smooth power transfer. Built around LuK’s OE-focused design approach, it helps maintain proper clutch engagement and reduces the stress that can come from using a solid flywheel in the wrong application.

Compatible with select BMW 323i, 325i, 328i, 330i, 525i, 530i, X5, and Z3 models, this LuK DMF019 flywheel is a direct-fit transmission component for vehicles that rely on dual-mass construction for driveline refinement.

Key Features

• Dual mass flywheel design for smoother drivetrain operation
• Flywheel diameter: 24 in. (9.449 in. listed in alternate units)
• Flywheel inner diameter: 14.65 in. (5.768 in. listed in alternate units)
• Flywheel cup depth/step height: -0.362 in. (-9.2 mm)
• 113-tooth ring gear specification
• OE-style fitment for select BMW manual transmission applications

Detailed Description

LuK DMF019 is built as a replacement dual mass flywheel for BMW vehicles that were originally equipped with this style of flywheel. The dual-mass construction helps isolate engine vibration from the transmission, which is important for preserving clutch feel, gearbox operation, and overall driveline smoothness. LuK notes that using a solid flywheel in place of the correct DMF can contribute to accelerated wear in engine mounts, transmission components, and even the crankshaft.

This part cross-references AMS Automotive 167019 for the same application. LuK DMF019 is a practical choice for BMW 325Ci, BMW 330i, and BMW X5 service work where OE-style flywheel geometry and damping characteristics matter.

What It Helps Address

• Excess drivetrain vibration during acceleration and shifting
• Harsh clutch engagement or inconsistent pedal feel
• Premature wear caused by an incorrect solid flywheel setup
• Transmission noise related to flywheel damping loss
• Stress on engine mounts and related driveline components

Installation Notes and Tips

Verify transmission type and vehicle build date before ordering, especially for 2004-2005 BMW 325Ci and 325i models marked non-sequential transmission, and for 2004 BMW X5 applications listed through 09/30/2003. Confirm tooth count, diameter, and step height against the original part before installation. Because this is a precision drivetrain component, installation should be performed with proper flywheel and clutch service procedures.

Quality Assurance

LuK is known for OE-level clutch and flywheel engineering, and the DMF019 follows that standard with application-specific tuning for the listed BMW models. The part number DMF019 is used for direct replacement identification across multiple catalog references, including BMW 323i, 325i, 330i, and related applications.
