This part is used with the PDK drivetrain on selected Porsche 991.2 Carrera models.

What This Part Does / Functions:
•  Connects the engine crankshaft to the PDK drivetrain assembly
•  Helps smooth engine torque pulses before they reach the transmission
•  Reduces drivetrain vibration, noise and harshness
•  Supports smooth power transfer through the PDK system
•  Helps protect gearbox and driveline components from shock load
•  Replaces a worn, noisy, heat-damaged or failed original flywheel
•  Provides correct Genuine Porsche fitment, balance and specification
•  Supports factory Porsche drivability and transmission refinement.

Why Replace This Part?
A dual-mass flywheel is exposed to heat, torque load, engine vibration and repeated drivetrain load changes. Over time, the internal damping mechanism can wear, the friction surface can become heat affected, or the flywheel can develop excessive rotational play. A worn or failed dual-mass flywheel may cause vibration, rattling, harsh engagement, drivetrain shudder or transmission-related noise.

Replacing it with a Genuine Porsche dual-mass flywheel helps restore smooth PDK operation and OE Porsche driveline quality.

Common Symptoms of a Worn Dual-Mass Flywheel
•  Rattling noise from the bellhousing area
•  Vibration at idle or under load
•  Drivetrain shudder during take-up of drive
•  Harsh or uneven engagement
•  Noise when switching the engine off
•  Excessive rotational play in the flywheel
•  Heat marks, scoring or damage on the flywheel surface
•  Wear found during gearbox or drivetrain inspection.

When to Replace This Part
•  During PDK gearbox removal if the flywheel shows wear
•  If excessive flywheel play or noise is found
•  If drivetrain vibration is traced to the flywheel
•  If the flywheel friction surface is heat damaged, cracked or scored
•  During major drivetrain or engine repair
•  If the internal damping mechanism has failed
•  When replacing related PDK clutch or transmission components

Where It Fits on the Car
This dual-mass flywheel fits between the engine crankshaft and the PDK transmission / drivetrain assembly. It forms part of the rotating drivetrain connection between the engine and Porsche dual-clutch transmission.

Correct installation requires Porsche workshop procedures, correct torque settings and inspection of related transmission, clutch and fastening components.

Dual-mass Flywheel
High-quality LuK dual-mass flywheel for Porsche 911 Type 991.2 Carrera models equipped with the PDK dual-clutch transmission.

Fits:
For cars with PDK transmission only
Porsche 991.2 Carrera / S 2017 - 2019

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.

Diagram ref. 5

The rear main seal seals the rear crankshaft exit point to prevent engine oil from leaking into the bellhousing or transmission area. A correctly fitted seal is essential for maintaining oil system integrity and keeping the clutch, flywheel, torque converter, and gearbox area free from oil contamination.

Functions
•  Replaces the rear main crankshaft oil seal
•  Helps prevent engine oil leaks from the rear crankshaft area
•  Supports correct engine oil sealing
•  Helps protect clutch, flywheel, and transmission components from oil contamination
•  Suitable for engine, clutch, flywheel, or gearbox service
•  Replaces hardened, worn, cracked, leaking, or damaged rear main seals
•  OE Match replacement for Porsche engine sealing repair.

Why Replace This Part?
Rear main seals are exposed to heat, oil pressure, crankshaft rotation, age, and engine vibration. Over time, the seal can harden, wear, crack, or lose sealing tension. A leaking rear main seal may cause oil drips between the engine and gearbox, oil contamination around the bellhousing, clutch slip on manual vehicles, burning oil smell, or failed inspection. Replacing the seal helps restore reliable engine sealing and prevents further oil leakage.

When to Replace This Part
•  Oil is leaking between the engine and gearbox
•  Rear main seal leakage is confirmed
•  The gearbox has been removed for service
•  Clutch, flywheel, or torque converter work is being carried out
•  The original seal is hardened, worn, cracked, or damaged
•  Engine rebuild or major service work is being completed
•  Preventative replacement is required while access is available.

Where it fits on the car
This seal fits at the rear of the crankshaft, between the engine and transmission area. It forms part of the engine oil sealing system.

About Flywheel / Torque

Porsche Flywheels & Torque Converters | Smooth Power Transfer & Engine Balance

Flywheels and torque converters are vital components in your Porsche’s drivetrain, ensuring smooth power transfer from the engine to the transmission. The flywheel provides rotational balance and stores kinetic energy for manual gear changes, while the torque converter in automatic models performs a similar role — transferring engine torque hydraulically for seamless acceleration.

At Design911, we supply precision-engineered flywheels and torque converters designed to meet or exceed original performance specifications. Each component is manufactured from high-grade materials, ensuring strength, balance, and reliability under all driving conditions. Whether you’re restoring a classic 911 or maintaining a modern PDK-equipped Porsche, our range provides the quality and performance your drivetrain demands.

What Do Flywheels & Torque Converters Do?

Both components play critical roles in the performance and drivability of your Porsche, acting as torque-transfer systems between the engine and gearbox.

Flywheels (Manual Transmissions):
Store rotational energy to maintain engine smoothness. Provide a friction surface for clutch engagement. Aid in gear transitions by balancing engine speed and torque.

Torque Converters (Automatic Transmissions):
Transfer torque through fluid dynamics between engine and gearbox. Enable smooth gear shifting without clutch operation. Multiply torque for efficient acceleration and smoother driving.

Together, they ensure seamless operation, smooth starts, and optimal power delivery from engine to transmission.

Why Do Flywheels & Torque Converters Fail or Wear Out?

Over time, both flywheels and torque converters experience wear due to high rotational forces, friction, and heat cycles.

Common Causes of Failure Include:

  • Heat damage or warping from clutch slippage (flywheels).
  • Cracked or worn ring gear teeth affecting starter engagement.
  • Fluid contamination or internal seal leaks (torque converters).
  • Bearing wear leading to vibration or imbalance.
  • Excessive torque or misalignment from modified engines.

Symptoms of failure may include clutch chatter, transmission shudder, vibration during acceleration, or slipping during gear changes. Ignoring these signs can lead to further drivetrain damage.

Why Replace your Flywheel or Torque Converter?

Replacing worn flywheels or torque converters restores smooth torque delivery, reduces vibration, and ensures reliable clutch or transmission performance. Upgraded lightweight flywheels improve throttle response, while performance torque converters enhance acceleration and drivability.

Key Benefits:

  • Restores smooth engine-to-transmission power delivery.
  • Eliminates vibration, slippage, and engagement issues.
  • Improves clutch or automatic transmission performance.
  • Balances rotational mass for smoother idling and shifting.
  • Available in lightweight or performance designs for tuned Porsches.
  • Ideal for clutch replacement, transmission rebuilds, or performance upgrades.

It’s strongly recommended to replace the flywheel or torque converter during any major clutch or gearbox service for long-term reliability and balanced performance.

Highlights

  • Premium Porsche flywheels and torque converters.
  • Precision-balanced for smooth, vibration-free operation.
  • Manufactured from high-strength, heat-treated materials.
  • Available for manual, automatic, and PDK Porsche models.
  • Enhances drivability, acceleration, and transmission longevity.
  • Essential for gearbox rebuilds, clutch services, and performance tuning.
