2004 Volkswagen Jetta Flywheels and Flexplates

LuK: New flywheels are a smart alternative! The flywheel is an integral part of clutch replacement. It must provide a smooth, flat surface for proper clutch operation. Pairing your clutch set with a new LuK flywheel is a smart, cost-effective alternative to resurfacing. All new – never remanufactured – every component is engineered and manufactured to OE specifications, including ring gear and dowel pins.

Converts Dual Mass Clutch to a Solid Flywheel type Clutch Assembly – Includes Flywheel. All the components necessary for the first time conversion. Valeo solid flywheel conversion kits are designed to replace standard fit dual mass flywheels by using a long travel damper system in the clutch friction plate. Valeo solution to replace the Dual Mass Flywheel Original Equipment ( ) This clutch plate replicates the movement and damping characteristics of a dual mass flywheel meaning driver comfort is not affected. If a standard clutch friction plate is used with a solid flywheel conversion, the damping effect of the dual mass flywheel is removed so could possibly cause damage to the engine or gearbox. Valeo conversion kits DO NOT use standard clutch friction plates. Contained in the conversion kit is a clutch plate that has been specially and specifically designed and tested for the application it is listed for.

Product Features:

• Full engine and gear box protection
• Noise and Vibration Dampening
• Excellent driver comfort
• Increased reliability and durability
• Increased clutch life (no wearing parts in the flywheel)
• Better thermal resistance
• Increased capacity for torque transmission

LuK dual-mass flywheels absorb engine vibrations before they are transmitted to the driveline where they can create gear rattle. These units feature a built-in damper designed to isolate engine torque spikes and prevent transmission damage. By design, dual-mass flywheels cannot be resurfaced. This all makes the LuK dual mass flywheel the ideal solution. With one drawback: the higher the mass reactance of the vibrating masses, the more excessive the resonance increase and associated torque peaks. With the dual mass flywheel, this would be easily perceived when starting and stopping the engine; much more easily than with a conventional clutch system. Additionally: the smaller flymass of the engine has less of a stabilizing effect on the speed fluctuation of the engine. Thanks to decades of experience in clutch building, the LuK specialists were able to find an excellent solution to this problem. An additional damping device effectively prevents resonance overload. In normal operation, however, this additional damping device has no function and the torsional vibrations of the engine are filtered out by spring dampers. Friction and spring rate – the correct ratio is important. For optimal vibration isolation and soft resonance passage when starting and stopping the engine, the ratio between friction and spring rate must be optimal. The length of the springs is a key factor: The softer a spring, the more efficiently vibrations are isolated. The extra-long springs of the latest generation of dual mass flywheels significantly reduce the spring rate compared to a first generation dual mass flywheel. In routine driving operations, excessive resonance increases are kept almost completely away from the gearbox.

Product Features:

• Top driving comfort
• Absorbs vibrations
• Prevents noise
• Enables comfortable, low-revs driving
• Saves fuel
• Relieves crankshaft and gearbox

LuK: Don’t gamble – stay with the original LuK DMF! The LuK DMF prevents damages solid flywheels may cause. The LUK Dual Mass Flywheel (DMF) is individually fine-tuned for every type of car. The risks of using solid flywheels are numerous – from increased wear of engine mounts through gearbox failure to damaged crankshafts.
