Luk DMF137 Clutch Flywheel

LuK DMF137 Dual Mass Flywheel

The LuK DMF137 is a dual mass flywheel engineered for direct replacement use in select Volvo applications. Built around the original LuK DMF design approach, it helps control drivetrain vibration and supports smoother clutch engagement in vehicles such as the Volvo C30, V50, C70, S40, S60, and V70.

With a 23.9 in. flywheel diameter, 15.2 in. inner diameter, and 144 teeth, this clutch flywheel is specified for precise fitment and consistent operation. The LuK DMF137 is a fitment-based solution for drivers searching for a Volvo C30 dual mass flywheel, Volvo V50 flywheel replacement, or LuK DMF137 for Volvo S40 and S60 applications.

Key Features

• Dual mass flywheel design for drivetrain vibration control
• Flywheel diameter: 23.9 in. / 9.409 in.
• Flywheel inner diameter: 15.2 in. / 5.984 in.
• Flywheel cup depth/step height: -0.299 in. / -7.6 mm
• 144-tooth ring gear specification
• OE-style fitment for select Volvo manual transmission applications
• LuK part number DMF137 for catalog and cross-reference lookup

Detailed Description

LuK designs dual mass flywheels to reduce the drivetrain stress that can occur when a solid flywheel is used in place of the original system. By separating torsional pulses from the engine before they reach the transmission, the DMF137 helps maintain smoother operation and supports the original drivability characteristics expected in compatible Volvo platforms. This part cross-references Sachs DMF91186 for the same application.

Compatible With: 2008-2012 Volvo C30, 2010-2011 Volvo V50, 2005-2007 Volvo V50, 2006-2010 Volvo C70, 2004-2007 Volvo S40, 2005-2007 Volvo S60, and 2005 Volvo V70. If you are replacing a worn flywheel on a Volvo C30, V50, or S40, DMF137 provides the correct fitment-focused replacement path.

What It Helps Address

• Excess drivetrain vibration during acceleration and shifting
• Harsh clutch take-up or inconsistent engagement feel
• Wear related to using a solid flywheel in a dual mass application
• Stress transferred to engine mounts and gearbox components
• Noise and driveline harshness associated with a failing flywheel

Installation Notes and Tips

Confirm the flywheel diameter, tooth count, and step height against the original part before installation. Inspect the clutch assembly, release components, and related drivetrain parts for wear while the transmission is removed. Proper torque procedures and manufacturer service specifications should be followed during installation.

Quality Assurance

LuK is known for OE-level drivetrain engineering, and the DMF137 follows the original dual mass flywheel concept used to protect the transmission and related components in the intended Volvo applications. Part number DMF137 is cataloged for accurate identification and replacement matching.
