What This Product Does

Mounted to the crankshaft, the flywheel stores rotational energy and provides the contact face against which the clutch operates. It forms part of the mechanical connection carrying engine torque through the clutch to the gearbox.

Functions

  • Provides a working surface for clutch engagement.
  • Stores energy as the engine rotates.
  • Supports torque transfer into the transmission through the clutch assembly.

Technical Details

  • Part number: 93010220403.
  • Additional supplied reference: 93010220400.
  • Application: Porsche 911 SC, 3.0L, 1978–79.
  • Internal diagram: crankshaft 911 1978-83; model designation SC; application note -79.
  • Supplied application information quotes 180–188 hp

Symptoms of Fault

Judder during initial clutch engagement, vibration under load or clutch slip can warrant inspection of the flywheel. These symptoms do not establish a flywheel fault on their own: clutch condition, contamination, mounts and other drivetrain components should also be assessed.

Why Replacement Matters

Cracks, heat damage and excessive surface wear can make a flywheel unsuitable for continued service. During clutch work, assess its condition before fitting replacement clutch components. OE Match focuses on Porsche replacement applications, using original references and specification checks to identify suitable parts.

FAQs

Does clutch replacement always require a new flywheel?
No. The decision depends on inspection findings and the applicable service limits, rather than clutch replacement alone.

Can the existing flywheel be resurfaced?
Have a specialist assess whether machining is permitted for the particular component and whether it can remain within the required dimensions.

What about the retaining bolts?
Follow the vehicle-specific workshop instructions for bolt renewal, tightening sequence and torque. Check related bearings and mounting components while access is available.
