6-speed GT sports manual transmission (option code: 486)

Porsche 991 4.0L GT3 / GT3 RS 2017 - 2020
 * engine code: DGGA, DGGB

Diagram ref no 16

The LuK 415097010 cross-references Porsche OE 9P1105262D and is designed as a stock-replacement dual-mass flywheel for the high-revving naturally aspirated GT3 drivetrain.

Positioned between the engine crankshaft and clutch assembly, the dual-mass flywheel performs an important role in transferring engine torque while controlling torsional vibration before it reaches the gearbox.

This helps retain the smooth clutch engagement, controlled drivetrain response and transmission refinement expected from the factory Porsche GT3 manual drivetrain.

Designed for the GT3 Manual Drivetrain

The 991.2 GT3 combines its naturally aspirated 4.0-litre flat-six engine with Porsche's 6-speed GT sports manual transmission on manual-equipped cars. The dual-mass flywheel is specifically designed to work between these two major drivetrain components. Its internal damping system helps control the torsional pulses generated by the engine before they are passed through the clutch and into the gearbox.

Correct flywheel operation contributes to:
•  Smooth torque transfer
•  Progressive clutch engagement
•  Reduced transmission vibration
•  Reduced gearbox resonance
•  Controlled drivetrain behaviour
•  Improved low-speed refinement

What Does a Dual-Mass Flywheel Do?

Unlike a conventional single-piece flywheel, a dual-mass flywheel contains two primary rotating sections linked by an internal damping mechanism.

The primary mass connects to the crankshaft while the secondary mass interfaces with the clutch.

Internal springs and damping components allow a controlled degree of movement between the two sections, helping absorb rotational irregularities created by the engine.

This reduces the amount of vibration transmitted into the gearbox and helps maintain smooth operation throughout the drivetrain.

Why Replace a Worn Dual-Mass Flywheel?

A dual-mass flywheel operates under substantial rotational load and is exposed to repeated acceleration, deceleration and clutch engagement cycles. Its internal bearings and damping components can wear over time.

Possible symptoms of a worn or damaged flywheel include:
•  Rattling from the clutch or bellhousing area
•  Excessive vibration at idle
•  Clutch judder
•  Vibration during acceleration
•  Clunking when starting or stopping the engine
•  Increased gearbox noise
•  Excessive rotational free play
•  Irregular clutch engagement
•  Drivetrain vibration when engine load changes

Correct diagnosis is recommended because similar symptoms can also originate from the clutch, engine mounts or transmission components.

LuK Drivetrain Technology

LuK specialises in clutch and flywheel technology and is widely recognised for its development of dual-mass flywheel systems.

The 415097010 is designed to provide the fit and operating characteristics required by the Porsche manual GT drivetrain while controlling torsional vibration between the high-revving engine and gearbox.

For owners carryingut a factory-style repair, it provides a premium replacement alternative while retaining dual-mass flywheel operation.

Recommended Replacement Items

When replacing the flywheel, it is advisable to inspect the complete clutch system at the same time.

Consider checking or replacing:
•  Clutch friction disc
•  Clutch pressure plate
•  Release bearing
•  Pilot bearing
•  Flywheel mounting bolts
•  Pressure-plate bolts
•  Rear crankshaft oil seal
•  Clutch release components
•  Transmission input shaft seal

Because gearbox removal is required to access these components, replacing worn related parts during the same repair can help avoid duplicated labour.
