Product Information
Flywheel With Starter Ring Gear, 6 Bolt Type 215mm.
The OE Match Flywheel with Starter Ring Gear, 6 Bolt Type, 215mm is a high-quality replacement drivetrain component designed to transfer engine power smoothly to the clutch and transmission while providing the engagement surface for the starter motor. Manufactured to OE specifications for fit, balance and durability, this flywheel is engineered to deliver reliable performance and factory-correct operation.  

Fits:
  • Porsche 911 1965-1968 2.0L / 912 SWB (F)
  • Porsche 914 (1970-1976)  
Note: early 911's might need to change the starter motor to later type (part number 901604102DX)

Featuring an integrated starter ring gear and 6-bolt mounting configuration, the flywheel serves as a critical component of the clutch and starting systems. Precision-machined to maintain proper rotational balance and clutch engagement characteristics, it helps ensure smooth engine operation, consistent clutch performance and dependable engine starting.  

What This Product Does:
  • Transfers engine torque to the clutch assembly and transmission.
  • Provides rotational mass to smooth engine operation.
  • Supports stable idle and drivability characteristics.
  • Features an integrated starter ring gear for starter motor engagement.
  • Provides the friction surface for clutch engagement.
  • Helps reduce drivetrain vibration and harshness.
  • Maintains proper balance within the engine and drivetrain assembly.

Symptoms Of Wear Or Failure:
  • Clutch vibration or shudder during engagement.
  • Difficulty engaging gears smoothly.
  • Excessive drivetrain vibration.
  • Starter motor engagement problems.
  • Grinding noises during engine starting.
  • Visible damage or wear to the starter ring gear teeth.
  • Hot spots, scoring or cracks on the clutch friction surface.
  • Premature clutch wear.
  • Unusual noises from the bellhousing area.
  • Reduced overall clutch and drivetrain performance.

Why Replacement Matters:

  • The flywheel is subjected to constant torque loads, heat cycles, clutch friction and engine vibration throughout its service life. Over time, the friction surface can become worn, warped or heat-damaged, while the starter ring gear may suffer tooth wear from repeated starter engagement.
  • A worn flywheel can negatively affect clutch performance, causing vibration, poor engagement and accelerated wear of clutch components. Damaged ring gear teeth may also lead to starter motor engagement issues, making engine starting difficult or unreliable. If left unresolved, flywheel problems can contribute to costly clutch and drivetrain repairs.
  • Replacing a worn or damaged flywheel restores smooth clutch operation, reliable starter engagement and proper drivetrain performance. An OE Match replacement provides factory-style fitment, precision balancing and durable construction, ensuring dependable operation and helping preserve the driving characteristics expected from your Porsche.
