Dual-mass Flywheel. Porsche 991.2 Carrera 2017-19 PDK  ❭  9P1105264

Dual-mass Flywheel
Genuine Porsche dual-mass flywheel for Porsche 991.2 Carrera models with PDK transmission. This original Porsche flywheel is designed for Porsche dual-clutch transmission applications, helping smooth drivetrain operation, reduce vibration and support correct factory power transfer.

Fits:
For cars with PDK transmission only
Porsche 991.2 Carrera / S 2017 - 2019
Porsche 991.2 Carrera 4 / 4S   2017 - 2019
Porsche 991.2 Carrera GTS/ 4GTS   2017 - 2019

Diagram ref no 13

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.
