My flywheel is grooved and needs to be machined.
-Does anyone know the minimum thickness of the flywheel surface where the clutch disc mates? -the thickness I get using my cheap calipers is 4mm thickness on the face. -what is the minimum thickness after a machine shop cuts the face? |

The image is actually specifically for the 914-6. There are no official specs for the 914-4 flywheels that I know of.
The specs should be OK as a general guide, but they are not actually for the four-cylinder flywheels... --DD |

I finally just bought a new flywheel (from Pelican, IIRC), and although I can't remember what the specks of the new one were, I know they didn't match what's shown in the diagram. |
