zetor 7711 clutch adjustment

[cra82]

Hi
I need some help to adjustment the clutch fingers at my zetor 7711. Can anybody help me what is the correct mm for pto and driving fingers?
Also, I not sure where to Measure the mm from? The clutch has like 2 surfaces. A high outer surface at where mounting blots are placed and a and an inner lover surface close to the finger.
Thanks Carsten
