901 Flywheel tolerance check

[Nditiz1]

I am confused by the flywheel tolerances.

I'm looking at buying a used flywheel and the numbers look decent, but I don't understand which value is good for C.

A = 23.01 mm
B = 39.3 mm
C = 9.4 mm

When new
A = 22.5 mm
B = 39.0 mm
C = Worn out when 11.000mm

So as A gets worn down, in this case the gap increased by .5 mm C would decrease from whatever it started as. How would C ever become greater than what it started as?

I assume this is for a 2.0L 215mm flywheel. I'm wondering if the number you're being given for C is correct. Had to look at a diagram to remind myself of the dimensions. 11 mm is the minimum. I don't see how this number could start out lower and increase over time, unless the flywheel was machined in a non-standard way.

Here's a link to the diagram I looked at.

Not sure if it's part of the puzzle, but the number being quoted for the used flywheel you reference seems more in line for thickness of a later style 225mm flywheel. I believe those start out at 9.5 mm and have a wear limit of 8.5 mm.

This is a 215mm flywheel. Does anyone know what C started as on a stock 215mm flywheel?
