Flywheel Step Specification

[tekenaar]

I received this manual by Deutsche Luftpost a little while ago and promptly perused it, cover to cover. Though everything's in black-and-white, the manual is filled with photos and diagrams in much the same way my earlier Rekord PII factory manual is. It has the absolute best "blow-up" carb diagrams in it and two items which I had not been able to find information on in 30+ years.

The most interesting to everyone here is a dimensional flywheel drawing with the factory spec for the clutchface "step" . . . Opel flywheel clutch faces are stepped, not flat like most American cars, but the step dimension is not found in any factory manual . . . that I'm aware of anyway!

So, here it is: Flywheel step - 4.5mm +0.1mm (0.177" +0.004")
