Cylinder bores out of round - how much a acceptable?

[Thuppu]

Ok, I see that now more clearly, thanks. Isn't 0.08mm quite much?

I was thinking that was the wear limit of the bore..? But the manual don't say anything about the roundness(and about the shape if bigger in the other end and smaller in the other, don't know the word for this, conical?), so maybe the same specs is for that also?

Read pg 36/93 again. It basically says: Measure in 3 locations (as specified). Measure "A" and "B" in those three locations. Compare all six values. Maximum overall deviation between the narrowest and the widest values = 0.08 mm.

Done.

Is 0.01-0.02mm acceptable? Where goes the line?

Maximum is 0.08 mm as per page 36/93 in this:
