Diagram ref no 13

The LuK 415117509 directly cross-references Porsche OE number 9P1105264 and provides an OE-quality replacement for a worn or damaged original dual-mass flywheel.

Designed specifically for use with the Porsche PDK transmission and its wet-clutch system, the dual-mass flywheel forms an important connection between the engine and transmission. Its internal damping system helps absorb torsional vibration generated by the engine before it reaches the gearbox, providing smoother torque transfer and reducing unwanted drivetrain vibration and resonance.

The LuK 415117509 is an ideal stock-replacement solution when carrying out transmission repairs or replacing a worn original flywheel while retaining factory-style drivetrain characteristics.

This Porsche reference is associated with the 991.2 Carrera crankshaft / dual-mass flywheel assembly.

Designed for PDK Transmission

This flywheel is designed specifically for Porsche's PDK dual-clutch transmission.

Unlike a conventional manual gearbox clutch arrangement, the PDK uses a dual-clutch system to provide rapid gear changes while maintaining continuous power delivery.

The dual-mass flywheel helps isolate torsional vibration between the engine and transmission, supporting:
•  Smooth power transfer
•  Reduced drivetrain vibration
•  Reduced transmission resonance
•  Refined low-speed operation
•  Controlled torque delivery
•  Improved drivetrain comfort

Correct flywheel operation is therefore important for both transmission refinement and long-term drivetrain performance.

What Does a Dual-Mass Flywheel Do?

A dual-mass flywheel consists of two primary rotating sections connected through an internal damping system.

The engine-side mass is connected to the crankshaft, while the transmission-side mass interfaces with the gearbox.

Internal springs and damping components absorb rotational irregularities produced by the engine before they reach the transmission.

This helps reduce:
•   Gearbox vibration
•   Drivetrain resonance
•   Rattling and harshness
•   Shock loads during changes in torque
•   Unwanted vibration transmitted through the vehicle

LuK Drivetrain Technology

LuK is a specialist manufacturer of clutch and flywheel systems and has extensive experience in dual-mass flywheel technology.

Its dual-mass flywheels are engineered to control torsional vibration while transmitting engine torque effectively to the transmission.

The 415117509 is designed to match the original fit, form and operating characteristics required by the Porsche PDK drivetrain.
