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? |

I used to post that pic, then found out that brand new German flywheels were out of spec (dimension C) according to it. (IMG:style_emoticons/default/wink.gif)
If I had 4mm, about .160" I'd tell the shop to remove just enough for clean up, Then you may likely have to grind the raised part of flywheel bolt heads off flat. Depending how much you had to take off the flywheel face you may have to put a shim under the release bearing arm pivot bolt on the trans. (note the 4mm you measured is likely dimension C but I'm guessing you are measuring in the wrong place compared to the chart.) |
