Luk DMF040 Clutch Flywheel

LuK DMF040 Dual Mass Flywheel

The LuK DMF040 is a dual mass flywheel engineered for 2002-2006 Nissan Altima and 2002-2006 Nissan Sentra applications. Built around LuK’s OE-focused DMF design, it uses a vehicle-specific tuning approach to help control drivetrain vibration and reduce the stress that can occur with a solid flywheel conversion.

Key Features

• Dual mass flywheel design for smoother engine-to-transmission operation
• 11.811 in. / 30 mm flywheel diameter
• 0.28 in. / 7.1 mm flywheel cup depth or step height
• 15.4 in. / 6.063 in. flywheel inner diameter
• 125-tooth ring gear configuration
• OE-style fitment for Nissan Altima and Nissan Sentra manual transmission service applications
• Cross-reference part numbers include AMS Automotive 167302 and Sachs DMF91140

Detailed Description

LuK DMF040 is a clutch flywheel built as a dual mass flywheel for specific Nissan passenger car applications. The design is tuned to absorb torsional vibration and maintain driveline refinement, which is important in vehicles such as the Nissan Altima and Nissan Sentra when replacing a worn flywheel. Using the correct DMF helps preserve the intended behavior of the clutch and transmission system, while the 125-tooth layout and listed diameter and step-height dimensions support proper OE-style replacement fitment.

This part cross-references AMS Automotive 167302 and Sachs DMF91140 for the same application.

What It Helps Address

• Clutch chatter during engagement
• Excess drivetrain vibration at idle or under load
• Noise caused by a worn or damaged flywheel assembly
• Premature wear on engine mounts and transmission components
• Driveline stress associated with improper solid flywheel replacement

Installation Notes and Tips

Confirm flywheel diameter, inner diameter, step height, and tooth count before installation. Inspect the clutch, release components, and related hardware for wear while the transmission is removed. For Nissan Altima and Nissan Sentra fitments, verify the vehicle’s model year and transmission configuration against the application listing before assembly.

Quality Assurance

LuK states that its dual mass flywheel design is individually tuned for each vehicle application and developed to support OE-level driveline behavior. The DMF040 follows that application-specific approach for 2002-2006 Nissan Altima and 2002-2006 Nissan Sentra service needs.
