323i flywheel minimum thickness

Post by bflan2001 »

I'm having a hard time locating the factory specs for the 323i flywheel. I'm in the US and all the info I can find only pertains to the 325i since we never got the 323i here. I'm sure the runout is within spec, I just need a minimum thickness.

Does nobody have a service manual with this spec in it? I've searched through the factory US manual, the Bentley manual, Haynes & Chiltons and none of them have it. I know the factory european manual has to have it, I just need someone to look it up for me.
