Product Information
Full details
This LuK Dual Mass Flywheel (DMF) is designed for manual transmission vehicles, specifically compatible with various Mercedes-Benz C-Class, E-Class, SLC, and SLK models. It offers a direct replacement for OEM part numbers including 274 030 05 05 and A 274 030 05 05, featuring 8 mounting bores and including a pilot bearing for essential clutch system function. While it restores smooth engagement and reduces drivetrain shock, a key consideration is the recommendation to replace the clutch kit simultaneously for optimal longevity and cost-effectiveness.

FAQs
What is a Dual Mass Flywheel (DMF)?
A Dual Mass Flywheel is a complex component designed to absorb engine torsional vibrations. It consists of two masses connected by springs and damping mechanisms, which significantly improves driving comfort and reduces stress on the transmission and other drivetrain components compared to a traditional solid flywheel.
Why is it recommended to replace the clutch kit with the DMF?
The clutch disc, pressure plate, and release bearing wear down over time. When replacing a DMF, these clutch components are already disassembled. Replacing them at the same time ensures that the new DMF is not subjected to uneven wear from old clutch parts, and it prevents you from having to perform the same labor again soon if the clutch wears out shortly after the DMF replacement. It's a matter of long-term economy and reliability.
How do I know if my DMF needs replacing?
Symptoms of a failing DMF include excessive vibration or shuddering during acceleration, rattling noises from the engine bay (especially at idle or when the clutch pedal is released), rough clutch engagement, and difficulty shifting gears. A professional inspection is recommended for accurate diagnosis.
What is the function of the pilot bearing?
The pilot bearing (or bushing) is located in the crankshaft and supports the end of the transmission input shaft. It ensures the input shaft is properly aligned when the clutch is engaged and helps reduce wear on the input shaft and crankshaft.
Is this flywheel compatible with my Mercedes-Benz model?
This flywheel is designed for specific Mercedes-Benz C-Class, E-Class, SLC, and SLK models with manual transmissions. Please verify compatibility by checking the OEM part numbers listed in the product description against your vehicle's existing part or consult your vehicle's service manual or a dealership.
Can I replace a solid flywheel with this Dual Mass Flywheel?
This DMF is intended as a direct replacement for vehicles originally equipped with a Dual Mass Flywheel. Replacing a solid flywheel with a DMF, or vice versa, may require significant modifications and is generally not recommended without professional guidance and specialized kits, as the entire clutch system and engine management may need to be adjusted.
Troubleshooting
Excessive vibration or shudder during acceleration.
This could indicate a worn or failing Dual Mass Flywheel. Ensure the clutch kit was also replaced simultaneously, as worn clutch components can contribute to this issue. Consult a professional mechanic for diagnosis.
Clutch engagement feels rough or jerky.
Check for proper installation and torque of the flywheel and clutch components. A worn pilot bearing or an incorrectly installed clutch disc can cause rough engagement.
Noise during clutch pedal operation (e.g., grinding, rattling).
This may point to issues with the release bearing, pilot bearing, or internal wear within the DMF. Have the clutch system inspected by a qualified technician.
Difficulty shifting gears.
Ensure the clutch is fully disengaging. Check the hydraulic clutch system for leaks or air. If the DMF or clutch disc is damaged, it can affect clutch operation and lead to shifting problems.
Pros and Cons

Setup, Compatibility & Care
Compatibility: This LuK Dual Mass Flywheel (415088110) is specifically designed for manual transmission Mercedes-Benz models. It is compatible with vehicles using OEM part numbers: 274 030 05 05, 2740300505, 274 030 06 05, 2740300605, 274 030 07 05, 2740300705, A 274 030 05 05, A2740300505, A 274 030 06 05, A2740300605, A 274 030 07 05, and A2740300705. Confirm your vehicle's specific requirements and VIN against these references before installation.
Setup: Installation requires specialized tools and knowledge of clutch and flywheel replacement procedures. It is strongly recommended that this part be installed by a qualified mechanic. The flywheel must be torqued to the manufacturer's specifications and the pilot bearing must be properly seated. Crucially, it is highly advised to replace the entire clutch kit (clutch disc, pressure plate, and release bearing) at the same time as the flywheel. This ensures optimal performance and longevity, as all components will have a similar service life remaining.
Care: Dual Mass Flywheels are internal components and do not require routine user maintenance. However, their longevity is dependent on proper driving habits and correct installation. Avoid excessive slipping of the clutch, especially under load, as this can generate excessive heat and accelerate wear. Ensure that the clutch system is always properly adjusted and that the correct clutch kit is used during replacement.
