Luk DMF177 Clutch Flywheel

LuK DMF177 Dual Mass Flywheel

The LuK DMF177 is a dual mass flywheel built for specific Jeep applications, including the 2002-2005 Jeep Liberty and 2003-2004 Jeep Wrangler. With a 10.157 in. / 25.8 mm flywheel diameter, 16.8 in. / 6.614 in. inner diameter, and 115 teeth, it is engineered to match the drivetrain requirements of the original equipment setup.

Key Features

• Part number DMF177 for direct catalog identification
• Dual mass flywheel design for OE-style drivetrain damping
• Flywheel diameter: 10.157 in. / 25.8 mm
• Flywheel inner diameter: 16.8 in. / 6.614 in.
• 115-tooth ring gear configuration
• Flywheel cup depth/step height: 0

Detailed Description

LuK DMF177 is a clutch flywheel designed around the demands of the original drivetrain, with the dual mass construction helping isolate torsional vibration before it reaches the transmission. LuK notes that solid flywheels can increase stress on engine mounts, transmission components, and even the crankshaft; this DMF is tuned for the vehicle application rather than using a one-size-fits-all approach. This part cross-references Sachs DMF91114 for the same application.

Compatible With 2002-2005 Jeep Liberty and 2003-2004 Jeep Wrangler, this flywheel is a fitment-specific replacement for vehicles that require the DMF177 configuration. Jeep Liberty and Jeep Wrangler owners looking for a LuK DMF177 replacement should verify the tooth count and diameter against the original part before installation.

Common Problems This Part Addresses

• Excessive drivetrain vibration at idle or under load
• Noise from a worn or failing dual mass flywheel
• Premature wear on transmission and clutch components
• Stress transfer that can affect engine mounts and crankshaft life
• Irregular engagement caused by flywheel wear or imbalance

Installation Notes and Tips

Confirm the flywheel diameter, inner diameter, and 115-tooth count match the removed unit before installation. Inspect the clutch assembly, release components, and related drivetrain parts for wear while the transmission is out. Because this is a vehicle-specific dual mass flywheel, proper alignment and torque procedures should follow the service information for the exact Jeep application.

Quality Assurance

LuK manufactures this dual mass flywheel as an OE-style replacement engineered for the listed Jeep applications. The DMF177 reflects LuK’s application-specific approach to flywheel tuning and drivetrain protection.
