I just bought a 1979 Porsche 911 Turbo and had to replace the belts. Does anyone on the reflector have a Porsche Workshop Manual that can tell me what kilogram (Kg) tension is specified in the Workshop Manual for setting up these belts using the Porsche V-belt tension gauge (actually the Gates Kricket V-Belt tension gauge).

I have not yet been able to find a reasonably-priced copy of the Porsche 911 Workshop Manual for the 72-83 years to buy. Thanks in advance for your help.
