Luk DMF146 Clutch Flywheel

LuK DMF146 Dual Mass Flywheel Overview

The LuK DMF146 is a dual mass flywheel engineered for Volvo S60 and Volvo V70 applications that require precise drivetrain damping. Built around LuK’s original dual mass flywheel design, it helps isolate torsional vibration and supports smoother power transfer through the transmission.

For 2004-2007 Volvo S60 and Volvo V70 fitments, this flywheel is matched to the vehicle application rather than a universal solid-flywheel substitute. The LuK DMF146 is a direct choice for drivers addressing flywheel wear, drivetrain noise, or vibration concerns on these Volvo models.

Key Features

• Dual mass flywheel design for vibration isolation and smoother clutch engagement
• Flywheel diameter: 23.9 in. / 9.409 in.
• Flywheel inner diameter: 15.3 in. / 6.024 in.
• Flywheel cup depth/step height: -0.346 in. / -8.8 mm
• 144-tooth ring gear
• Engineered for 2004-2006 Volvo S60 and Volvo V70, plus 2007 Volvo S60 and Volvo V70 to chassis #3735358
• Part number: DMF146

Detailed Description

The LuK DMF146 dual mass flywheel is built to manage the torsional forces created by the engine before they reach the clutch and gearbox. That damping function is important on Volvo S60 and Volvo V70 models, where drivetrain refinement and component protection depend on the flywheel’s ability to absorb vibration. LuK identifies this DMF as application-specific, with dimensions and tooth count matched to the vehicle platform. This part cross-references NDMF146 for the same application.

Use the LuK DMF146 when servicing a worn or damaged flywheel on 2004-2007 Volvo S60 and Volvo V70 vehicles. The part number DMF146 is also useful when verifying replacement against OE-style catalog listings and interchange references.

What It Helps Address

• Clutch shudder during takeoff
• Excess drivetrain vibration at idle or under load
• Gearbox noise related to flywheel wear
• Premature wear on engine mounts from vibration transfer
• Stress on crankshaft and transmission components caused by a worn flywheel

Installation Notes and Tips

Confirm vehicle fitment by year, model, and chassis break before ordering. This application includes 2007 Volvo S60 and Volvo V70 only up to chassis #3735358, along with 2004-2006 Volvo S60 and Volvo V70. Inspect the clutch system, release components, and related drivetrain parts during service so the new flywheel is installed into a clean, properly measured assembly. Verify ring gear tooth count and flywheel dimensions against the removed part before installation.

Quality Assurance

LuK is known for original-equipment-style dual mass flywheel engineering, and the DMF146 follows that application-specific approach for Volvo S60 and Volvo V70 service. The design is intended to preserve the damping characteristics expected from the original DMF layout and reduce the risks associated with replacing it with a solid flywheel.
